Abstract:

Over the years there has been much debate on extraction versus non extraction in orthodontics. In 1907, Angle believed everyone have the capacity to have all teeth (32) in functional occlusion and that the complete set of teeth will provide the best aesthetic. He advocated Wolf �??s Law which states �??the bone would form in response to stress�?�. Therefore, he attempted to treat with expansion of the dental arches. Case (1964) has criticized Angle�??s non-extraction approach. He explained the effect of excessive dental arch expansion on the facial aesthetic, as dental protrusion will be the result of that approach. Later in 1960�??s, the debate start to reopen again. It is thought that opinions tend to oscillate with desired aesthetics and litigation. Proffit (1994) have reviewed the frequency of extractions for 40 years and have found the following: 30% had extractions in 1953; 76% had extractions in 1968 and 28% had extractions in 1993. He have suggested that the reason for decline in the frequency of extractions since 1968 might be due to concern about facial aesthetics, TMD and that extractions are not a guarantee for stability.
