Abstract

Objective: The purpose of this study is to determine the short-term skeletal and dental effects that occur as a result of Class II malocclusion correction utilizing the Carrière Distalizer as compared to best-matched controls. Methods: This is a retrospective cohort cephalometric study using lateral cephalometric films of 25 (14 male, 11 female, average age 13y 6m) class II patients consecutively treated with the Carrière Distalizer compared with 36 (19 male, 17 female, 13y 2m) untreated class II control subjects from a historical database best-matched based upon age, sex and skeletal classifications. Pretreatment and posttreatment lateral head films were analyzed with conventional cephalometric analysis to evaluate treatment effects. Results: Class II correction was accomplished by 2.46 apical base change, 1.24 mm distal movement of the maxillary movement, 4.8˚ distal tip and 2.64 mm mesial movement of the mandibular molars. Other profound treatment changes occurred include significant increased lower incisor proclination, 4.83˚ and a steepened functional occlusal plane, 1.3˚. Conclusion: The Carrière Distalizer is an effective means to establish a class I occlusal platform in approximately 4 months during the initial phase of comprehensive orthodontic treatment.
