摘要
Abstract
Objective:To compare occlusual changes after orthodontic treatment between adults' and adolescents' skeletal class II malocclusion with average mandible plane angle. Methods; In the study, 30 adolescent girls and 30 women who had skeletal class II and Angle class II , division 1 malocclusions were selected. The two groups were matched by sex, treatment period and method. Cephalometric radiographs taken before and after treatment were traced and measured. Student' s t-test was used. Results; After treatment upper incisors retracted and erupted in both groups. Upper molars moved forward and downward in the adolescents but only moved forward in the adults. Lower incisors retracted but their inclination remained constant in both groups. More intrusion of lower incisors was shown in the adults. Lower molars showed more forward and upward movement in the adolescents than in the adults. The adults experienced more clockwise rotation of occlusion plane than the adolescents. Conclusion: Growth enhances the correction of deepbite in adolescent skeletal class II malocclusion.关键词
