| ABSTRACT Objectives: This study evaluated the impact of the upper third molar on the distalization using a carriere motion appliance. Subjects and methods: The study was conducted on 12 class II malocclusion orthodontic patients (three males and nine females) with class II malocclusion; they were divided into two groups; the first group with the presence of upper third molar consisted of 6 patients (two males and four females) with mean age 16.5±2.25, the second group with the absence of upper third molar consists of 6 patients (1males and 5female) with mean age16.5±2.42. Cast superimposition for the upper and lower jaw and lateral cephalometric was taken before (T1) and after the first phase treatment with CMA (T2). Results: The inter-group difference was non-significant; there is some difference in significant value within each group which increased within group B than group A, especially in upper first molar sagittal movement. Conclusions:( 1) CMA provides an effective tool for treating mild to moderate class II malocclusion. (2) Extraction of the upper third molar increases the amount of upper buccal segment distalization. (3) Extraction of the upper third molar decreases the anchorage loss in the lower jaw by decreasing the amount of mesialization of lower teeth. | ||||
