Prostitution Through the Functionalism Essay Example For Students

Prostitution Through the Functionalism Essay All through America and the whole world, prostitution thrives quickly. Prostitution is another ceaseless war like fetus removal, which society feels is improper. This unethical behavior drives functionalists, who apply functionalism to this social issue, on a pursuit to make sense of why prostitution is the thing that it is today. Functionalism is the best hypothesis for taking a gander at prostitution. It permits us to perceive how prostitution changes alongside different parts of society. Some inquire as to why prostitution spreads out of control through our urban areas and lanes. This is a simple inquiry for functionalists, prostitution prospers since it fulfills sexual requirements that can't be met elsewhere(Henslin 51). Whores nearly appear to fill in as an outlet for explicitly disappointed men. At the point when a man can't discover an accomplice he generally holds the alternative of paying for sexual joy. A functionalist, Kingsley Davis, reasoned that whores give a sexual outlet to men who: experience issues in building up sexual connections, can't discover long haul accomplices, have a messed up relationship, need sexual delight that is characterized as indecent, want brisk sexual satisfaction without connection, are interested, and are explicitly disappointed in marriage. From this it is indicated that by addressing such needs prostitution capacities as a type of social power over sexual conduct. This is advantageous on the grounds that it brings men with sexual wants from reluctant accomplices to accomplices that are willing yet at a specific cost. This without a doubt cuts down the quantity of assaults and rape for some random society. Additionally it acquires trashy hookers or whores that appear to corrupt any given city or society. The functionalist hypothesis is the most ideal approach to see prostitution through a sociological viewpoint. Functionalists consider prostitution to be a methods for controlling or diverting sexual practices (Henslin 53). Whores address the issues of men who in any case don't have ladies consistently accessible to them. Additionally it addresses the issues of a man since it is cheap, non passionate and a short lived relationship. Through taking a gander at prostitution we see that it continues since it serves social capacities. This works by overhauling individuals who are explicitly disappointed. Whores mitigate pressures that in any case may be set on individuals who are reluctant to take an interest. Without the guide from whores invigorating the un-animated, there may be other social issues that become greater issues, for example, assault rape, seize and some more. Functionalism permits seeing each capacity that prostitution serves in a general public. Since prostitution fills in as a capacity in a more concerning issue there are a couple diverse vital methods of handling this social issue. The principal way is the most evident and that is legitimize prostitution. Authorizing prostitution would have two or three effects on society. Much equivalent to it is today men would be fulfilled at a cost, however that is better than men attempting to get fulfillment from the reluctant. Second the administration could burden the business similarly as it would some other business in the United States. Third the ladies or whores could have real employments as opposed to watching and run from the police as they work their activity. In spite of the fact that this appears as a decent arrangement, it might reverse discharge. With this being such a significant social issue it is difficult to cause it to appear to be OK to the bigger society. On the off chance that prostitution was sanctioned it would permit all the more drab ladies to wander the roads. Which at that point prompts lower class guys amassing these territories, which prompts more debasement and a higher crime percentage. This at that point prompts another social issue made, an apparently endless predicament. The main arrangement is to leave prostitution at the spot it is at today. .uac9405da5211e852714050109dec8bd7 , .uac9405da5211e852714050109dec8bd7 .postImageUrl , .uac9405da5211e852714050109dec8bd7 .focused content territory { min-tallness: 80px; position: relative; } .uac9405da5211e852714050109dec8bd7 , .uac9405da5211e852714050109dec8bd7:hover , .uac9405da5211e852714050109dec8bd7:visited , .uac9405da5211e852714050109dec8bd7:active { border:0!important; } .uac9405da5211e852714050109dec8bd7 .clearfix:after { content: ; show: table; clear: both; } .uac9405da5211e852714050109dec8bd7 { show: square; progress: foundation shading 250ms; webkit-change: foundation shading 250ms; width: 100%; murkiness: 1; progress: haziness 250ms; webkit-progress: mistiness 250ms; foundation shading: #95A5A6; } .uac9405da5211e852714050109dec8bd7:active , .uac9405da5211e852714050109dec8bd7:hover { obscurity: 1; change: darkness 250ms; webkit-progress: mistiness 250ms; foundation shading: #2C3E50; } .uac9405da5211e852714050109dec8bd7 .focused content zone { width: 100%; position: rel ative; } .uac9405da5211e852714050109dec8bd7 .ctaText { fringe base: 0 strong #fff; shading: #2980B9; text dimension: 16px; textual style weight: intense; edge: 0; cushioning: 0; text-enhancement: underline; } .uac9405da5211e852714050109dec8bd7 .postTitle { shading: #FFFFFF; text dimension: 16px; textual style weight: 600; edge: 0; cushioning: 0; width: 100%; } .uac9405da5211e852714050109dec8bd7 .ctaButton { foundation shading: #7F8C8D!important; shading: #2980B9; outskirt: none; fringe span: 3px; box-shadow: none; text dimension: 14px; text style weight: striking; line-stature: 26px; moz-fringe range: 3px; text-adjust: focus; text-enrichment: none; text-shadow: none; width: 80px; min-stature: 80px; foundation: url(https://artscolumbia.org/wp-content/modules/intelly-related-posts/resources/pictures/straightforward arrow.png)no-rehash; position: supreme; right: 0; top: 0; } .uac9405da5211e852714050109dec8bd7:hover .ctaButton { foundation shading: #34495E!important; } .uac9405da5211e85 2714050109dec8bd7 .focused content { show: table; stature: 80px; cushioning left: 18px; top: 0; } .uac9405da5211e852714050109dec8bd7-content { show: table-cell; edge: 0; cushioning: 0; cushioning right: 108px; position: relative; vertical-adjust: center; width: 100%; } .uac9405da5211e852714050109dec8bd7:after { content: ; show: square; clear: both; } READ: Alexander The Great Essay It isn't legitimate using any and all means, however the discipline isn't excessively brutal.

It is valid, prostitution fulfills the sexual needs of men which are not in any case fulfilled. On the off chance that we took prostitution totally away we would simply be starting a more noteworthy social issue inside itself. .

Different styles of leadership have become evident through time Essay

Various styles of administration have gotten clear through time between the two sexual orientations - Essay Example Be that as it may, these distinctions additionally serve to make varieties in the way of administration and the executives inside the association. Various styles of authority have gotten apparent through time between the two sexual orientations. In this way, the inquiry that asks to be addressed is whether a relationship exists among sexual orientation and styles of authority embraced by administrators inside proper associations? Assuming this is the case, to what degree do the character contrasts sway in the decision of an initiative style just as supporting its utilization through a limited timeframe? This doesn't infer that there is a sure ideal authority style that interests most to a given sexual orientation. Positively not; there needs agreement that one authority style is best in spite of the fact that there is proof through research that shows a sharing of normal attributes and inclinations by those in administration positions, which tends to applies pressure upon the individ uals who are extraordinary (Carpenter and Sanders, 2006). This proposition looks at the authority attributes and inclinations comparable to sex. ... n for the firm, discussing this vision with both profundity and clearness to different individuals from the association and coordinating and supporting their deliberate endeavors towards the achievement of this vision. During the early times of the mechanical insurgency, administration was focussed on fundamentally guaranteeing benefit for the association. This methodology supported poor administration structures and regularly prompted net offense and maltreatment of administrative authority by those in administrative limits. Present day initiative uses the wide billet of hypothetical models that have been created and tried through time. Management’s administration work additionally takes cognisance of developing concerns and issues, for example, morals and corporate social duty, notwithstanding an accentuation of center standards of responsibility, obligation and reasonableness (Dyck and Neubert, 2008). Is there a superior head in men than ladies or the other way around? This has been a wellspring of extraordinary contention and much enthusiasm of most scholars and supervisors the same. There have been two ways to deal with this basic inquiry in the executives: Firstly, that people in a general sense vary in the manner in which they lead others inside an association (Carpenter and Sanders, 2006). Furthermore, and which is the broadly acknowledged situation by most social researchers is that there are moderately no huge contrasts in how people lead given a controlled domain (Dubrin, 2009). The individuals who buy in to the previous way of thinking, for the most part credit this distinction to the â€Å"female voice†. This has, notwithstanding, been disregarded by most standard specialists. Experimental investigation into these methodologies has just served to facilitate the discussion and disarray in this administrative region. Studies did somewhere in the range of 1961 and 1987 have been refered to by

Determination of Gold Nanoparticle Sizes

Assurance of Gold Nanoparticle Sizes Daron Chua Summary In this test, the goals of this test was to comprehend the different utilizations of gold nanoparticles and to synthersize Colloidal gold nanoparticles by fluid concoction technique. Z-normal of nanoparticles for the ruddy arrangement and the grayish arrangement was 60.86 and 50.40 individually. Anyway it was noticed that there were pollutions in the arrangement subsequently influencing the Z-normal. All things considered, the shade of the arrangement and the Z-normal didn't count. It was found that by including salt into the arrangements there will be shading change. This is expected to NaCl collecting the nanoparticles together. This causes the nanoparticles to ingest the red light consequently mirroring the arrangement in an increasingly blue shading. Different techniques for framing gold nanoparticles and an assorted application for gold nanoparticles were noted. Presentation The targets of this test was to comprehend the assorted utilizations of gold nanoparticles. Colloidal gold nanoparticles were blended by methods for fluid synthetic strategy. Hypothesis Fluid Chemical Method The vast majority of the gold nanoparticles are created in a (fluid compound techniques) byreduction of hydrogen tetrachloroautate (H[AuCl4]). By dissolving H[AuCl4], the arrangement is quickly mixed while a decreasing operator is being included. This causes Au3+ particles to be decreased to nonpartisan goldatoms. As increasingly more of these gold iotas structure, the arrangement gets supersaturated, and gold continuously begins toprecipitatein the type of sub-nanometer particles. The remainder of the gold iotas that structure adhere to the current particles, and, if the arrangement is blended overwhelmingly enough, the particles will be genuinely uniform in size indicating the arrangement as red.To keep the particles from conglomerating, a type of balancing out operator that adheres to the nanoparticle surface is typically included. Likewise, gold colloids can be integrated without stabilizers bylaser ablationsin fluids. They can be functionalized with different natural ligands to make natural inorganic cross breeds with cutting edge usefulness. A few techniques that rotate around this thought are Turkevich strategy, brust technique and perrault technique, and so forth. Gold Nanoparticles Colloidal goldis a suspension particles ofgoldin a liquid, generally water. The fluid is normally either an extraordinary red shading (for particles under 100nm) or blue/purple (for bigger particles). As molecule size builds, the frequency of surface plasmon reverberation related ingestion movements to longer, redder frequencies. Red light is then assimilated, and blue light is reflected, yielding arrangements with a light blue or purple shading. An adjustment in temperature will likewise influence which the gold to be at an alternate vitality band. The breadth of gold nanoparticles decides the Wavelength of light ingested as appeared on the graph represented previously. Strategies Stock Solution 0.1g of H[AuCl4] was broken down in 500ml refined water to get 1.0mM hydrogen tetrachloroautate. 0.5g of Na3C6H5O7.2H2O (trisodium citrate get dried out) was broken up in 50ml of refined water to get 1% fixation. 0.5g of NaCl was broken down in 10ml of refined water. Analysis 20ml of 1.0mM H[AuCl4] was added to a funnel shaped flagon. The funnel shaped flagon was put in a blending hot plate and an attractive mix bar was included. 2 examples were readied. One was blended constantly even it was at breaking point. The other example quit blending once it was bubbled. 2ml of 1% arrangement of trisodium citrate get dried out was at that point added to the bubbling arrangement. Gold Sol was bit by bit shaped as citrate decreases the gold (III). Nearness of a colloidal suspension was seen by the impression of a laser bar from the particles. The arrangement of the two examples were being moved to two test tubes. 5 10 drops of 1M NaCl arrangement was included into one of the test tubes and the shading change of the arrangement was being watched. The two arrangements in the test tubes were being separated with a 0.45 um syringe channel. The arrangements were thusly moved into an example holder. The Malvern Zetasizer Nano S Light dispersing hardware was utilized to quantify the size of the nanoparticles in the two example holder. (0.47 refractive record was utilized.) Results Results as follows : Arrangement with turn even at breaking point : Shading watched : Reddish Brown Size of Gold nanoparticle : 63.77 with 3 pinnacles Pinnacle 1 : 41.1, Peak 2 : 433.2, Peak 3 : 3913 Arrangement without turn at breaking point : Shading watched : Grayish/Bluish/Clear Size of Gold nanoparticle : 53.31 with 3 pinnacles Pinnacle 1 : 143.9, Peak 2 : 1.651, Peak 3 : 3213 Estimation Standard Calibration 67.54nm 63.63nm = 2.91nm Size of Gold nanoparticle (Reddish/Brown) Z-Average 63.77nm 2.91nm = 60.86 nm Size of Gold nanoparticle (Grayish/Blue) Z-Average 53.31nm 2.91 nm = 50.40 nm Conversation From the outcomes, Z normal for the rosy earthy colored arrangement was determined at 60.86nm, while the grayish/blue was determined at 50.40nm. Regarding hypothesis, the outcomes closed by Z-normal is wrong. By right, anything at the blue move is of a bigger molecule size. By perusing off the most elevated force pinnacles of the two diagrams of red and blue arrangements, size of particles were 41.1nm and 143.9nm individually. In a perfect world 1 top in the diagram would be ideal. Different pinnacles that influenced the Z-normal were most likely polluting influences. This mistake might be because of lack of regard of accepting all types of gear accommodated the examination were perfect. Consequently there could be soil or residue caught at all. So as to get significantly littler molecule sizes, including of all arrangements ought to have been done gradually, for instance including trisodium citrate drop by drop, permitting the bead to completely respond with the arrangement before including another. With that, the blending part is no uncertainty the most vital procedure parameter of the investigation. Different components that influence molecule sizes are blending time and temperature and focus. Various temperatures inside the response will cause warmth and mass exchange slopes. A low centralization of arrangement will yield excessively low of an outcome and ultimately for our case, blending time. Lacking blending time/stoppage of blending will refuse the nanoparticles to scatter. Subsequently having a bigger molecule size. 1. Clarify the elements of trisodium citrate utilized in this test. In this test, Trisodium citrate goes about as a lessening operator to decrease hydrogen tetrachloroautate so as to create spheroidal gold paticles. By and large, the more prominent the focus and intensity of the diminishing specialist. The littler the resultant gold particles in the suspension. 2. Record for the shading change saw in sync 4.6 In sync 4.6 of the down to earth booklet, NaCl arrangement is included into the arrangement causing a shading change. By including NaCl into the arrangement, it causes the gold nanoparticle surface charge to turn impartial, causing the nanoparticle to total. Accordingly the arrangement shading changes from red to dark blue. Concerning the grayish pale blue arrangement, it goes to an even more clear arrangement. A bigger molecule size will cause assimilation of the red light henceforth mirroring the arrangement as blue. 3. State two different combination techniques for gold nanoparticles next to the fluid compound strategy. Sonolysis One strategy for the test age of gold particles is by sonolysis. The procedure depends on ultrasound. It utilizes the response of a fluid arrangement of HAuCl4withglucose. The diminishing agentsare hydroxyl radicals and sugar pyrolysis radicals. The morphology got is that of nanoribbons with width 30â€50nm and length of a few micrometers. These strips are truly adaptable and can twist with edges bigger than 90â °. At the point when glucose is being supplanted by cyclodetrin (a glucose oligomer), just round gold particles are acquired. Square Copolymer-interceded Method Other technique for gold nanoparticles is by utilizing a square copolymer.In this amalgamation philosophy, square copolymer assumes the double job of a diminishing operator just as a settling specialist. The arrangement of gold nanoparticles contains three principle steps: decrease of gold salt particle by square copolymers in the arrangement and development of gold groups, adsorption of square copolymers on gold groups, also, further decrease of gold salt particles on the surfaces of these gold groups for the development of gold particles in steps. This strategy generally has a constrained yield (nanoparticle focus), which doesn't increment with the expansion in the gold salt fixation. As of late a test has been done that by including trisodium citrate in 1:1 molar proportion expands the gold arrangement by numerous gold. 4. Refer to some other application notwithstanding those referenced under presentation. Gadgets Gold nanoparticles are intended for use as conductors from printable inks to electronic chips. As the universe of hardware become littler, nanoparticles are significant parts in the chip plan. Nanoscale gold nanoparticles are being utilized to interface resistors, conductors, and different components of an electronic chip. Test Gold nanoparticles are generally thick, making them helpful as tests for transmission electron microscopy. Impetus Gold nanoparticles are utilized as impetuses in various synthetic responses. The outside of a gold nanoparticle can be utilized for specific oxidation or in specific cases the surface can lessen a response (nitrogen oxides). Gold nanoparticles are being produced for energy component applications. These innovations would be valuable in the car and show industry. End All in all, the test was not extremely effective as there were pollutions in the arrangement. Thus the Z normal was being influenced. Anyway targets were met as colloidal gold was being orchestrated and uses of gold particles were additionally comprehended.

Youth Sub Culture

Research on contributing variables to negative Research on Contributing Factors to Negative Youth Subculture and Preventing It 26 November 2012 Table of Contents Introduction3 Youth Needs Met In Subculture3 Supporting Youth Before Negative Subculture Does7 Conclusion9 Introduction Youth subculture is a subculture by adolescents with particular styles, practices and interests. It offers a specific culture to the young who are searching for somebody or some gathering that they can relate to. The attributes of the young subculture varies, it very well may be communicated through their design, discourse style, observation and social groups.Lots of times the adolescent subculture can be around a specific kind of music. There are numerous sorts of youth subculture out there that permit young people to relate to it as well as standardize their demeanors as per the subculture they relate to. A few subcultures develop the young people to communicate imaginatively, for example, punk, hip-jump, spray painting, beat boxing, cheerleading and Goth; some standardize their appearance of personality, similar to groups, geeks, fixation on a games group, and Emos (Wood, 2003).However, the threat is when adolescents are associated with contrary subculture like packs, punk, Goth, law breakers, or even Emos; these subcultures will support a reserved conduct that cause damage to self or others. Around the ages, ten to sixteen years of age, they are encountering a great deal of physical, enthusiastic, mental and social changes, subsequently these are not many of the contributing variables to the enthusiasm of subculture that will be talked about later on in this paper. This paper will learn about the contributing variable and impacts of the ever-changing pessimistic youth subculture and how help them.Youth Needs Met In Subculture Daniel Seigel (2001) conveys that a person’s personality is molded dependent on the cooperation of how a person’s relationship is bridled and a ppeared well and good in the mind. At age of a young person, an adolescent, as per Erikson (Stevens, 2008), is in a phase, which a kid is neither a youngster nor a grown-up. Life gets increasingly perplexing as there is an inward want to endeavor to make their own character. Subsequently they battle with social associations and test their own good issues.They want to be isolated from their own family so as to investigate and to distinguish themselves as an individual however where it counts inside, there is a need for that security of the limits gave by the family. Adolescents are continually in struggle with themselves let alone with their loved ones. The hunt is ceaseless until the internal identity is fulfilled. It is during this period (Hardy and Laszloffy, 2005) which makes this phase of life powerless against pessimistic youth subculture.Without the opportune individuals supporting the adolescent, they will in general end up with job disarray. In this way, how these adolescent comprehend their personality (Seigel, 2001) depends on how individuals assemble associations with them. Building connections is to take care of the requirements of the inward want of an individual. The subculture gives the requirements that a young ache for which can't be found in the home. Because of that reason a few young people are attracted to a particular subculture. There are a great deal of mental variables that negative subculture gives to the looking for youth which will be examined in this paper.Subcultures are not the same as nation to nation since young people are still especially subject to the social-monetary and political impact of the zone that they are in. The social-efficient and political impact adolescents in a roundabout way through the structure of the family and they can likewise impact them legitimately (Falk and Falk, 2005). For instance, the policy centered issue of family control like rehearsing the once kid strategy in China in 1978 and supporting the à ¢â‚¬ËœStop at Two’ arrangement in Singapore in 1975, influences the child rearing technique towards their children.Controlled by the legislature on labor, these youngsters turned out to be all the more valuable (Settles and Sheng, 2008; Ang and Dion H, 2006), consequently the child rearing strategies changes to assist their kids with performing at their best. A few guardians become increasingly tyrant to see the kids perform well in the general public, anyway it is additionally one of the enthusiastic disregards. Inside, they are loaded up with anger, gloom and misery in self; so when the young finds the negative subculture that gives the passionate needs that the adolescent longs for, they relax because of the new subculture this youngster has found.Negative subcultures that intrigue to these young are for the most part packs (Kirby, et al. , 2000). The negative subculture urges these adolescent to stand up and fight for them selves, to be versatile by conflicting with the d esires of the family and be defiant towards power. With the structure of these propensities in them, the youngster will gradually create introverted conduct like Conduct Disorder (CD), Oppositional Defiant Disorder (ODD) and Attention Deficit Disorder (ADD).In opposite of this, there is the other child rearing impact, for example, over defensive and spoiling mentality towards their kids. This causes the other sort of subcultures, specifically menaces and airheads. These adolescents looks and expects the group of friends that they are in to give them a similar insurance, acclaim and consideration that they have picked up in their home. The rich, spoilt and conspicuous or keen and energetic kind draws in a specific gathering of youth who urgently needs a similar benefit in the club and submit to these youths.Some of the subculture got from these can be sure if the estimation of the subculture is solid, for instance sports bunch that thinks building sound ways of life can manufacture t he youth’s fearlessness, mindfulness and physical wellness. Be that as it may if the games bunch is tied in with building distinction, the young will endeavor hard to fit in for acclaim and will create standoffish conduct like Conduct Disorder (CD). Such negativism in a subculture will lead these adolescent to build up an opportunity of misery and hazard. Financial aspects is additionally one of the contributing components in subculture. It influences the rich and the poor.Nowadays most young people will attempt all methods and approaches to procure cash (Haenfler, 2006). Review referenced that a few young people, works low maintenance to procure cash, some interest from their folks and some work in groups selling drugs, sex, pilfered or unlawful things, and even through selling of taken merchandise. Research from 1979 till 2009 found that packs who address the money related needs in a young are usually found in either the white collar class or the lower class families everyw here throughout the world (Falk and Falk, 2005) (Williams, 2007) (Wood, 2003) (Kirby, et al. , 2000) (Hardy and Laszloffy, 2005) (Haenfler, 2006).The greatest contributing element to an adolescent is the family. Having a family in Singapore isn't modest; the average cost for basic items in Singapore is high. A family unit pay of a fundamental requirements for a family in 2011 is 35% for a mid-pay family with compensation of $2000 †$3999; The 39% of the pay is spend on child’s essential instruction; 4% goes to Central Provident Fund Board (CPF) 75% of the pay earned by are added to these parts and guardians buckled down just to send them for educational cost (Perception of Policies in Singapore Survey (POPS)(2): Survey on Marriage and Parenthood (M7P) Package 2008, 2011)(MSS Monthly Payment, 2012).Due to the appeal of everyday costs in Singapore, Parents must strive to acquire a living in Singapore and a few guardians from that gathering will have a high propensity to dis regard the child’s enthusiastic necessities (Ng, Ho, and Ho, 2011). Albeit some recruit house cleaners to help give essential needs to the family like cleaning, cooking and to take care of the adolescent, there are a few young people who despite everything feel ignored on the grounds that the servants don't comprehend their necessities. These youngsters will at that point go to posses around their neighborhood.Some youth originate from broken families like maltreatment, groups, addicts and gay; a few adolescents originate from families that are comprised of single parent, blend and perfect guardians. Families assume a significant job in giving that security, love, consideration and limits that a young need during the quest for their personality. At the point when every one of these necessities are met, it builds up a decent and secure youngster parent connection (Bowlby, 2006). At the point when any of these are missing, and are not found from the steady condition, for exampl e, school and social administrations, these young people are powerless against be brought into contrary youth subcultures.They will fit themselves as indicated by the adolescent subculture that meets their hankering needs. In Singapore, negative youth subculture that these young could fit themselves into either Goth, groups, addicts and lesbian, gay, cross-sexual, transgender, addressing, intersex, and abiogenetic (LGBTQI). It can likewise happen to youth who originates from a perfect family like the instance of Ted Bundy who was executed in 1989 (Michaud and Aynesworth, 2000) Education and Social are another commitment in creating subculture. Singapore has extremely exclusive requirements as far as training and is notable or their high achievers. It is known to be one of the most boring instruction frameworks on the planet. In this way, adolescents who can't make up for lost time and score passing marks are effortlessly put down socially. On the off chance that a specific gathering of adolescents, who are keen, straight An achievers, concentrates extremely hard, whose essential leisure activity is to contemplate or has high IQ are viewed as geeks. In spite of the fact that this subculture was not made by them however it was mark by the individuals who don't have that capacity to deliver astounding outcomes (Falk and Falk, 2005).There are simply the other outrageous end who considered as disappointments for they can't accomplish results anticipated from them and are continually being put somewhere around classmates discovers security in posses. Posses can standardize the desires individuals have on them and to make new desires that are attainable and against individuals who hurt them (Hardy and Laszloffy, 2005). Socially, young people need to be distinguished, along these lines there are likewise a great deal of worry in the social game play known as

Early, Jubal Anderson

Early, Jubal Anderson Early, Jubal Anderson, 1816â€"94, Confederate general, b. Franklin co., Va., grad. West Point, 1837. After fighting against the Seminole in Florida he resigned from the army (1838), studied law, and practiced at Rocky Mount, Va. He fought briefly in the Mexican War. Early voted against secession in the Virginia convention (Apr., 1861), but when war broke out he became a colonel of Virginia troops. Promoted to brigadier general at the first battle of Bull Run (July, 1861), he fought in all the campaigns (1862â€"64) of the Army of Northern Virginia. He was prominent at Salem Church (see Chancellorsville, battle of ) and in the Gettysburg campaign (1863). In the Wilderness campaign (1864) he temporarily commanded A. P. Hill's corps, and when R. S. Ewell was forced to retire, Early assumed command of the 2d Corps. After Cold Harbor, Lee sent Early against Gen. David Hunter, who was threatening Lynchburg. Early drove Hunter westward and then marched down the Shenandoah valley, c rossed the Potomac, and moved on Washington. He defeated Lew Wallace in the battle of Monocacy (July 9, 1864) and was before the capital on July 11. The arrival of troops from Grant's army compelled him to withdraw to Virginia, but later in the month he again crossed the Potomac. His cavalry raided far and wide and burned Chambersburg, Pa., when that town refused to pay a ransom. In Sept., 1864, P. H. Sheridan moved against Early and, defeating him at Winchester and Fisher's Hill, drove him up the valley. Early returned and surprised Sheridan's army at Cedar Creek (Oct. 19) but was finally defeated. On Mar. 2, 1865, his small force was overwhelmed by Gen. George Custer, of Sheridan's army, at Waynesboro. Lee, although still confident of Early's ability, was forced by public opinion to remove him. At the end of the war Early fled the country and did not return until 1869. He resumed the practice of law and was associated with Gen. P. G. T. Beauregard in the Louisiana lottery.

A Comparison of One-Piece versus Two-Piece Dental Implants Introduction Modern dentistry involves the evaluation, diagnosis, prevention and treatment of diseases and conditions in the oral and maxillofacial region. This includes the restoration of function, comfort, aesthetics, speech and health. With seventy percent of persons in theU.S. population missing at least one tooth, one commonly encountered condition requiring treatment in today’s society is that of edentulism. The previous treatment of choice for any form of edentulism was some form of denture. For example, the most common treatment for one missing posterior tooth was a three unit fixed partial denture; however with the success, predictability and continued research of osseointegrated dental implants there has been a dramatic increase in the inclusion of dental implants as a viable treatment option. Osseointegrated dental implants initially received a poor reputation because the first attempt at anchorage within bone failed due to scar tissue forming between the bone and the implanted material. This allowed for epithelial down-growth potentially leading to native bacteria infecting these epithelial pockets resulting in an inflammatory reaction that could cause bone resorption and mobility of the implant. The status of dental implants did not change much until the late 1950s when aSwedish professor, Per-Ingvar Branemark, unexpectedly found a way to predictably form intimate bone-to-implant apposition of significant strength that could withstand load transfers. The basic principle was that if a hole was prepared in bone without traumatizing the tissues or overheating the bone an intimate bone apposition could be achieved with a biocompatible implantable device; he named this process osseointegration. Since then, millions of patients have been treated with dental implants using this principle (Chun et al. 2008). Following their introduction just over a half century ago, dental implants have since changed the lives of millions of people worldwide. Dental implants are surgically implanted into the jawbone and greatly improve appearance since they prevent the jawbone from shrinking. Moreover, dental implant patients are able to eat anything since dental implants look, feel and function like natural teeth (Dental Implant Offers Alternative to Dentures 2004). After trauma or years of bone resorption, though, patients can arrive for implant treatment with different level of bone volume, length and height of ridge, and inter-occlusal space. Some sites cannot accept the standard sizes of many available implants without site development. Bone augmentation is an option for increasing the available bone volume if a standard diameter implants is required by the clinician. For dental implants to be successful, the jawbone must have enough bone to support them. Tooth loss often leads to more loss of bone. The tooth loss may be caused by periodontal (gum) disease, dental caries (cavities) and infection, injury or trauma, or a developmental defect. If the bone under the gum is not tall enough, not wide enough or both, patients will need a procedure to add bone to their jaws before implants can be placed. The supportive quality of augmented graft, though, is debatable (Flanagan 2008) and therefore alternative size implants have been introduced. Over the past decade, endosseous implants of increasingly smaller diameters have been introduced into the field of dentistry. Endosseous implants are medical devices, regulated by FDA to ensure their safety and effectiveness. They are Class III devices, a category that covers life-supporting, life-sustaining, and implanted items (Modeland 1998). Implant diameter is the dimension measured from the peak of the widest thread to the same point on the opposite side of the implant. The diameter measures the outside dimension of the thread. This type of implants can be divided to two different groups, narrow diameter implants and mini implants. Narrow diameter implants are generally 2.75 mm to 3.3 mm in diameter. They are frequently used in cases of limited alveolar anatomy like in the edentulous space smaller than 5-6 mm, which is minimum requirement for conventional implants (Huang et al. 2010; Preoteasa et al. 2010). Typical areas for use of these implants are lower incisors. Mini dental implants are smaller than their small diameter counterparts, with diameters ranging from 1.8 mm to 2.4 mm and are provided for immediate stabilization of a dental prosthetic appliance after a minimally invasive procedure or for cases where traditional implants are impractical, , or when a different type of anchorage system is needed. Analysis of the success of this type of implant restoration has not been clearly determined. The term mini has also been used to describe very short length implants with standard or larger diameters. Background The importance of implant dentistry transcends the strictly clinical outcomes and the procedures may have lifelong and life-changing implications. For instance, Cash (2002) emphasizes that, â€Å"It is widely recognized that facial attractiveness is a social asset that results in greater acceptance by others, including peers, teachers, and employers. Conversely, unattractive facial features can be a social liability and results in peer rejection, academic difficulties, and (later) employment problems† (p. 342). Implant dentistry is a restorative procedure with oro-surgical aspects. It is highly predictable and the implants in all modern systems encounter very few problems with integration. The key     Questions for clinician choosing a system are how easily I can restore the implants? Is it better for patient cost wise, how this implant is clinically acceptable/good? In one-piece implants, the fixture and the abutment are made from one piece of titanium and integrated in o ne implant body that is inserted during a one stage implant surgical procedure. In 1950’s, Tramonte was the first to introduce the one-piece implant and it was used for immediate loading, however most   clinicians have continued to utilize two-piece implant systems for one-stage procedures. The implant-abutment junction constitutes a structural weakness, while the need to remove a healing abutment and replace it with a final abutment adds complexity to the procedure and adversely affect the healed or healing gingiva. The one-piece implant utilized in the many cases avoids both drawbacks. Aims In sum, the aim of this study was to examine the current available implant systems in the market and to compare one piece versus two piece implant and evaluate literature and carry out a differences study after applying selection criteria.   A secondary aim of the study was to assess the reduced surgical time and lab work and what factors affect the selection of one-piece or two-piece implant systems. Objectives The objective of this study was to assess the reduced surgical time and lab work and what factors affect the selection of one piece or two piece implant systems. To this end, the study explored the long-term success of the different implant systems and examined literary evidence in assessment of the cervical bone loss around the two different implant types after implant placement. Review of the Literature Four general designs of devices are currently in use in implant dentistry as shown in Table 1 below: Dental implants are a reliable and long-lasting replacement for missing teeth.  Ã‚  A dental implant consists of two parts. First there is a root form that is placed in the jaw. It is approximately the same size as a tooth root, and it takes the place of the root of the missing tooth. Usually a healing period is required for the process known as osseointegration—during which the bone grows in tightly around the root form so that it is solidly anchored. By tightly adapting the surgical site to the root form, this healing period can be shortened. Some practitioners offer what is called teeth in an hour, where the dental implant is placed into function immediately. This can be done, but there may be a trade-off between risk and patience here. When the healing time is rushed, there could be increased risk of failure. The visible part of the dental implant is the crown. An abutment is screwed into the root form and the crown is placed over it. If the process is done well, the end result is very functional, long-lasting, and highly esthetic (Dental Implants 2011). Advantages and Disadvantages of Dental Implants Disadvantages: There is usually a healing time required; and. They may be more expensive than other methods of tooth replacement. Advantages: Preparation of the adjacent teeth is not required. The old-fashioned method for replacing a missing tooth is with a dental bridge. A dental bridge requires preparing the adjacent teeth for crowns, and then the false tooth is suspended between those two crowns.   Avoiding this aggressive treatment of otherwise healthy teeth is desirable. Maintenance is less expensive. If a dental bridge has any trouble with any one of the three or more teeth involved, the entire restoration usually has to be replaced. Additionally, cleaning it properly requires the use of floss threaders, which most people find troublesome. A dental implant, however, can be brushed and flossed normally, and in the unlikely event that there is trouble with it later, no other teeth need to be involved in the treatment of the problem. They preserve the bone. When a tooth is extracted, the body senses the loss and begins to resorb the bone that used to support that tooth. In the case of multiple missing teeth, this can lead to facial collapse, inability to wear even removable teeth, or jaw fracture. This is in addition to the esthetic problems. The presence of a dental implant signals to the body that this bone is still needed, and these difficulties are prevented (Dental Implants 2011). Osseointegrated dental implants have become reliable and safely provide long-term prosthetic stability for edentulous clients of all ages. Dental implants are not an appropriate treatment for all persons. The basic objective of dental implantation is to provide an attachment mechanism for teeth or dentures. Dental implants can anchor lower or upper dentures, provide a method to replace partial or full dentures with fixed bridgework, provide a method of replacing a single tooth, improve chewing function and restore the feeling of natural tooth function, and improve the quality of life by removing the frustration associated with using dentures or removable bridgework (Ubell 1992). Today, implants are placed using both non-submerged and submerged approaches, and in one- and two-piece configurations. Previous work has demonstrated that peri-implant crestal bone reactions differ radiographically under such conditions and are dependent on a rough/smooth implant border in one-piece implants and on the location of the interface (micro gap) between the implant and abutment/restoration in two-piece configurations. Peri-implant bone loss is a highly complex phenomenon with numerous etiologies currently debated in the dental literature (Zamani 2008). Endosseous, root-form dental implants distribute occlusal stresses into the supporting bone as a function of their overall design and the amount of bone to-implant interface achieved. Various reports in the dental literature suggest that both high and low stresses can lead to margin bone resorption. Preservation of peri-implant marginal bone height thus depends, in part, on proper distribution of marginal stress; however, major variations in the abilities of different implant designs to resist and distribute vertical and lateral occlusal loads have been documented using three dimensional (3D) finite element stress analyses (FEA) (Zamani 2008). The ability of one-piece dental implant designs to maintain peri-implant crestal bone levels to the same degree as two piece implant designs has recently been questioned. The aim of the study by Zamani (2008) was to compare how the level of stresses generated by one-piece and two-piece implant designs simulated homogenous bone and to determine if load distributions were significantly different. Three-dimensional FEA code was used to simulate one-piece implants (1P) and two-piece implants with internal hexagon connections and assembled with friction-fit abutments (2P). The implant and abutment of the 2P model were designed with bonded interfacial surfaces to replicate the documented â€Å"virtual cold weld† between the assembled components, and this bonded relationship was also assumed in the analysis. All implant models were surrounded by a block of simulated homogenous bone that had linear elasticity with an average Young’s modulus value of 3 GPa, which is the mid-range stiffness value of cancellous bone. For the study models, a uniform, 2-mm thick bone material surrounded each implant, and it was assumed that bone-to-implant contact (BIC) was 100% with bonded interfacial surfaces. All the simulated implant-and-bone-block models adhered to the manufacturer’s protocol for implant placement. Identical load and boundary conditions were used for all of the study implants. The material properties for titanium alloy (Ti-6Al-4V) were used for implants, restorative parts, and retaining screws. Figure 2 below shows typical boundary conditions and mesh configurations used in various simulations. A compressive load of 222.4 N (50 lbs) at an offset with respect to the implant axis and at a 30-degree angle was applied to all the various assemblies. Average dental bone yield stress in compression is approximately 180 MPa. The vertical component of biting force in the incisor regions of adults is approximately 222 N (50 lb), which was used for this analysis with the assumption that 3.7 mm-diameter implants are often used in incisor region. Utilizing those parameters with a 2-mm thick bone, there was only a 3 MPa difference between 1P and 2P models that were 3.7 mm in diameter. Based on a comparison of these results with previous studies, Zamani (2008) concluded that no significant difference was found in bone stress concentrations between simulated 1P and 2P implants with the same length and diameter. It should also be noted that 2 mm of peri-implant bone is the borderline for the 3.7 mm-diameter study models; as the peri-implant bone increases in thickness, the maximum stress values of 1P and 2P merge exponentially according to the present calculations. For example, at 222.4 N (50 lb) of load, 1.6% is the maximum difference betw een these implants utilizing the present calculations (Zamani 2008). During the course of the Zamani (2008) study, it was observed that a residual plate that is less than 2 mm in thickness could have an adverse affect on bone stress levels and crestal bone maintenance. It is important to note that this same phenomenon has also been clinically documented in a prospective, multi-center clinical study that was conducted by the U.S. government and involved the placement of approximately 3,000 implants. The present study also noted that both vertical and lateral load stresses decreased in inverse proportion to an increase in implant diameter (Zamani 2008). Within the limitations of this study, it was found that one-piece implants create similar stresses to two-piece implants in the same length and diameter. Reported differences in marginal bone levels between one-piece and two-piece implants may be attributable to variables independent of implant design since other reports in the dental literature have not observed this same phenomenon (Zamani 2008). Most implant hardware in use today is made from titanium alloys. Coatings of calcium phosphates, carbon compounds, and titanium are sometimes added to promote successful bonding of the implant to bone. However, the coatings have not been shown to improve the bonding of the implant to bone, according to Sands. Due to the routine presence of bacteria in the mouth, there is a risk of infection of the tissue or bone surrounding the implant. There also is some risk that the additional stress of the implant on bones in the jaw will speed up bone resorption and lead to implant failure and possibly a toothless future. Persistent pain or discomfort, speech problems, nerve injury, and damage to adjacent teeth are rare but possible complications of implants (Modeland 1998). Carbon nanotubes have also been proposed by Price et al. (2004) as a possible new orthopedic/ dental implant surface material because of their unique mechanical, electrical, and cytocompatibility properties. Cell viability and number of human osteoblast CRL-11372 were determined after 3, 6, 11, and 24 hr of incubation by ethidium homodimer and calcein AM staining. The authors used conventional fibers (diameter 100 nm) and nanoscaled fibers (diameter 100 nm). The fibers agglomerated within 1 week in cell culture media to ropes of about 340 nm in diameter in the case of conventional fibers and about 670 nm in the case of nanoscaled fibers. The nanoscaled carbon fibers appeared to influence osteoblast viability less than their conventional dimensioned counterparts. The suspended carbon fiber agglomerates were taken up by the osteoblasts and were incorporated in lysosomal vacuoles (Price et al. 2004). This future application of carbon nanotubes as implant material is in itself a promis ing issue, but one of the key questions is do carbon nanotubes influence the differentiation of osteoblast progenitor cells and to what degree is the formation and activation of osteoblasts affected? (Helland et al. 2007). Conditions that can rule out dental implants include hypertension, heavy smoking, alcohol and drug abuse, chronic illnesses such as diabetes, bone deterioration, and bruxism (habitual tooth grinding), according to the University of Detroits Dr. Mentag. Endosseous implants are medical devices, regulated by FDA to ensure their safety and effectiveness. They are Class III devices, a category that covers life-supporting, life-sustaining, and implanted items. Under the 1976 Medical Device Amendments, FDA will require manufacturers of dental implants to submit data from controlled clinical studies to demonstrate the safety and effectiveness of their products or stop marketing them as early as 1990, according to FDAs Singleton. In sum, dental implants have arrived. They may not be the solution for every case of tooth loss, but for those who are candidates, implants promise an alternative to dentures. According to Cash and Pruzinsky, it is important to assess each dental implant candidate from a holistic perspective. â€Å"Assessing body image,† Cash and Pruzinsky advise, â€Å"first requires an understanding of what facets of the body are critical for the clinical issue of interest† (2002, p. 345). Three key measures are typically used in the dentofacial body image assessment as follows: It is important to examine specific components of the face, such as teeth, lips, mouth and facial profile. These components must be placed within the context of other body parts to assess the relative evaluation of dentofacial features compared to other facial and body components. Because most research on the psychological aspects of dentofacial body image focuses on functional and aesthetic changes that result from trauma, pain, or elective treatment, it is important to select body image measures that are sensitive to such changes (Cash Pruzinsky, 2002, p. 345). Based on their professional experience and empirical observations, Cash and Pruzinsky have used a modified version of the Secord and Jourard’s Body-Cathexis Scale. The modification involves the addition of five items related to the lower face, mouth, and facial profile (Cash, 2002). By making minor changes in some of the items, the modified instrument has been successfully used with children as young as 8 years and patients as old at 78 years (Cash, 2002). Methods This study used a critical review of the relevant peer-reviewed and scholarly literature to achieve the above-stated aim and objectives. This method is highly congruent with numerous social researchers who emphasize the need to thoroughly review what is known about a given topic in the course of the research. For instance, according to Gratton and Jones (2003), a critical reviewing of the timely literature is an essential task in all research.   â€Å"No matter how original you think the research question may be, it is almost certain that your work will be building on the work of others. It is here that the review of such existing work is important. A literature review is the background to the research, where it is important to demonstrate a clear understanding of the relevant theories and concepts, the results of past research into the area, the types of methodologies and research designs employed in such research, and areas where the literature is deficient† (p. 51). In th is regard, Wood and Ellis (2003) identified the following as important outcomes of a well conducted literature review: It helps describe a topic of interest and refine either research questions or directions in which to look; It presents a clear description and evaluation of the theories and concepts that have informed research into the topic of interest; It clarifies the relationship to previous research and highlights where new research may contribute by identifying research possibilities which have been overlooked so far in the literature; It provides insights into the topic of interest that are both methodological and substantive; It demonstrates powers of critical analysis by, for instance, exposing taken for granted assumptions underpinning previous research and identifying the possibilities of replacing them with alternative assumptions; It justifies any new research through a coherent critique of what has gone before and demonstrates why new research is both timely and important. Likewise, Silverman (2005, p. 300) suggests that a literature review should aim to answer the following questions: What do we know about the topic? What do we have to say critically about what is already known? Has anyone else ever done anything exactly the same? Has anyone else done anything that is related? Where does your work fit in with what has gone before? Why is your research worth doing in the light of what has already been done? Results and Outcomes As noted in the introductory chapter, the aim of the study was to examine the current available implant systems in the market and to compare one piece versus two piece Implant and evaluate literature and carry out a differences study after applying selection criteria. In addition, the study assessed the reduced surgical time and lab work and what factors affect the selection of one piece or two piece implant systems. The results of the research showed that implant dentistry is a restorative procedure that involves a number of oro-surgical aspects, but the procedure was shown to be highly predictable and the implants of all modern system encounter very few problems with integration. The key questions for clinician choosing a system will therefore involve a cost-benefit analysis concerning patient preferences and clinical acceptability. Discussion The research showed that at present, there are seven dental implant systems with a seal of approval by ADA on the market; these were Straumann implants, Nobel Biocares Branemark model and AstraTech implants being most popularly implemented and researched ADA approved implant systems (Dental implant systems 2011).   A major problem for implants, though, is the lack of jaw bone that occurs in 10% of prospective patients. Research is underway to find bone stimulators. These include hormones and the use of Gore-Tex, which encourages bone growth by blocking other cells from filling empty spaces in bone (Ubell 1992). In addition, the candidate for implants can have no history of drug abuse (potential for misuse of pain management drugs) and must possess realistic expectations of the outcome (Ebersole 1998). Conclusions and Recommendations The clinician’s long-term implant survival success rate depends on the preservation of the hard and soft tissue around implant after placement. Successful endosseous implant therapy requires integration of the implant with bone, soft connective tissue and epithelium. To help promote successful outcomes, the research showed that the three most widely used implant systems are Branemark, Straumann and AstraTech, each of which possesses its own characteristic surface topography finish. A comparison of these implant systems is provided in Table __ below. Comparison of Branemark, TiUnite, Straumann and AstraTech Implant Systems System Description One Piece Two Piece Branemark (http://www.nobelbiocare. com/en/products-solutions/implant-systems/default.aspx) Brà ¥nemark System dental implants are the most scientifically documented in the world and are backed by more than 40 years of published results on their safety, predictability, clinical success, and longevity. Key benefits: 1. Ideal for use in dense bone. 2. Enhanced osseointegration. 3. External hex connection. 4. Exceptional restorative versatility for all applications. The Branemark systems are indicated for both flapless and immediate function cases. Graftless procedures are also simplified with Zygoma and Shorty implants. The system offers complete solution packages for crown, bridge, and implant cases – from temporary to final restorations. Nobel Biocare offers a range of implants in two drilling protocols – parallel and tapered. Parallel is the most versatile drilling protocol, enabling fewer drilling steps in common indications and offering a passive fit in dense bone. Also, it can enhance stability in soft bone when under-preparation is possible. Tapered dental implants follow an easy-to-use, step-by-step drilling protocol. Surgical kits are logically and simply structured and drilling is the same for all indications. NobelActive is an advanced, next-generation dental implant featuring a unique, innovative body design and prosthetic connection. NobelActive is suitable for all indications and offers exceptional primary stability – even in compromised bone situations. It is particularly suited for use in the esthetic zone. Based on its ability to redirect during insertion, it provides clinicians with maximum placement flexibility. Key benefits: 1. NobelActive is an advanced dental implant that offers dental professionals various benefits. 2. NobelActive offers experienced surgical and restorative clinicians an enhanced set of options for cases involving soft to medium bone. 3. The prosthetic connection of NobelActive has been designed for maximum restorative flexibility. 4. The NobelActive surgical kits contain all the components needed to meet surgical requirements. NobelReplace Tapered – a part of the NobelReplace dental implant system – is the world’s most widely used, versatile, two-piece dental implant system. Suited for both starting or experienced restorative clinicians and surgical implant users, NobelReplace provides a simple, flexible, color-coded, multi-use implant system. It performs well in soft and hard bone, one- or two-stage procedures, flapless and flapped surgeries, as well as immediate and delayed loading procedures. And it supports Nobel Biocare’s powerful NobelGuide digital 3D diagnostics, treatment planning and guided surgery system. Key benefits: 1. A versatile, easy-to-use, predictable implant. 2. Its prosthetic versatility and tri-channel connection make NobelReplace well suited for all indications. 3. NobelReplace offers flexibility in individualized and prefabricated restorative options. Furthermore, due to its tactile internal tri-channel connection and color-coded implant diameters, it is accurate and easy to use. 4. Nobel Biocare offers a variety of kits for the NobelReplace dental implant system. Straumann (http://www.straumann.us/us-index/ products.htm) The company states that with respect to reliability, its products feature: 1. Implants designed for optimal tissue response. 2. Reduced healing time. 3. Morse taper connection for maximum stability. The company also cites the simplicity of their use: 1. A logical component structure. 2. Procedures that are easy to learn. 3. One surgical kit. Finally, the company emphasizes the versatility of its implant products: 1. Successful outcomes with any indication. 2. Free choice of surgical procedure. 3. A wide range of prosthetic options. The Straumann Bone Level Implant provides a solution for all bone level treatments. Its design is based on the latest technology and scientific know-how in implant dentistry. Moreover, it respects key biological principles, guarantees predictable esthetic results and offers simple handling in all indications. Other notable attributes include: 1. Optimized crestal bone preservation with Bone Control Design. 2. Reliable treatment predictability. 3. Pleasing aesthetic results. 4. Simplified handling. 5. Roxolid and SLActive combine high strength with excellent osseointegration to deliver more peace of mind in treatment with small diameter implants. 6. Flexibility of having more treatment options. 7. Roxolid provides a wider choice of treatment options with small diameter implants. This can facilitate selection of the optimal treatment for patients in specific clinical situations. 8. Designed to increase patient’s acceptance to implant treatment 9. The benefits of small diameter implants are gained by Roxolid that provides greater confidence when placing small diameter implants in patients. According to Controversies over Implant Connections and Surfaces (http://www.implantdirect.com/controversy/contro1_pt08-2.html), prior to 1986, Straumann sold TPS-coated implants with a machined abutment top that was part of the implant (i.e. one-piece design.) In 1986, the companys consulting International Team of Implantologists (ITI) developed the Bonefitâ„ ¢ System, which originally included threaded and non-threaded hollow-basket designs with a 2.8mm-high machined neck for one-stage surgery. A solid-screw, non-self-tapping design added later became known as the ITI implant. Because both of these implants require attachment of secondary prosthetic abutments, they are considered two-piece designs. AstraTech (http://www.astra tech.us) Astra Tech develops, manufactures and markets dental implants and advanced medical devices within urology and surgery.   Building on the proven success of TiOblast, OsseoSpeed is the first and only implant in the world with a chemically modified titanium surface, providing unique nano scale topography, that stimulates early bone healing and speeds up the bone healing process. The result of the micro-roughened titanium surface treated with fluoride is increased bone formation and stronger bone-to-implant bonding. Together with MicroThreadâ„ ¢ on the implant neck, OsseoSpeed provides true growing power in action for more reliable and effective treatment. The clinical benefits of OsseoSpeed are proven and well-documented. Complete descriptions of the company’s one-piece designs are available at http://www.astratechdental.us/Main.aspx/ Item/827544/navt/72677/navl/92618/nava/92619. The company reports that all of these dental implants have proven abilities to speed up the bone healing process. The unique OsseoSpeed implant surface, one of four key features in the Astra Tech BioManagement Complex, stimulates the early bone formation and provides stronger bone-to-implant bonding. The implant neck is designed with MicroThread that offers optimal load distribution and stress values. The Conical Seal Design of the Astra Tech Implant System allows for a strong and stable implant-abutment connection. In addition, the Astra Tech dental implants have proven clinically to maintain marginal bone levels (mean marginal bone reduction of only 0.3 mm over 5 years). Taken together, the research and empirical observations indicate that one piece implants are preferable in many cases because surgeries are minimally invasive, patients tend to experience little or no discomfort and the use of the one piece implant system also significantly reduces treatment time based on the elimination of the post-surgical visits traditionally involved in the removal of the healing abutment and place permanent abutment. Reflections Gingival aesthetics around natural teeth is based upon a constant vertical dimension of healthy periodontal soft tissues and the biologic width. Because of the subjective qualities involved in any aesthetical application, universal guidelines derived from the Golden Ratio can help guide the process (Cash Pruzinsky 2002).
