Method for evaluation of transverse dimension in self-ligating orthodontic treatment. A comparative study.

Knowledge of the best way to evaluate changes in transverse dimension produced by orthodontic treatment enables the estimation of potential space that may be generated and optimizes planning. The aim of this study was to compare two methods for measuring changes in transverse dimension following tooth alignment by passive self-ligating system: Method 1 (M1) considering palatal landmarks and Method 2 (M2) considering dental landmarks. Subjects were 12 patients of both sexes, aged 15 to 24 years old, with moderate crowding (Nance discrepancy -4 to -6 mm), who were treated with the Damon System at the Department of Orthodontics of the School of Dentistry, Buenos Aires University.
