Evaluation of the Soft Tissue Changes Following Functional and Camouflage Orthodontic Treatment in Class II Division I

The purpose of this study was to evaluate the esthetic changes following functional and camouflage treatment in Class II Division 1 malocclusion patients. Methods: cephalograms of 35 patients had Class II Division 1were selected. Those in group 1 (n=15) were treated with functional appliance, and those in group 2 (n= 20) were treated with fixed orthodontic appliance after premolar extractions. 35 cephalometric variables were selected to evaluate the esthetic changes following the orthodontic treatment. Dependent t tests were used to compare the cephalometric variables at the posttreatment stage and the cephalometric variables at the pretreatment stage in each group, and Independent t tests were used to compare the changes in cephalometric variables caused by the orthodontic treatment between the groups.
