Abstract
Objective To evaluate the chin bony morphological characteristics in adolescents with Angle class Ⅱ1 malocclusion by mandibular retrusion in different vertical facial types. Methods 60 female adolescents with Angle class Ⅱ1 malocclusion by man dibular retrusion were randomly selected with an average age of(12. 56±0. 67) years and divided into 3 groups according to man dibular plane angle:high angle group,average angle group and low angle group,20 cases in each group. Cepholagrams were taken and cepholametrics were employed for comparing the chin bony morphology. Results There were significant differences in chin height,curvature,chin angle,chin depth/height ratio and concavity among various groups(P<0. 05). Compared with the average and low angle groups,the high angle group exhibited the maximal chin height,curvature and chin angle,and the minimal chin depth/ height ratio and concavity(P<0. 05). The low angle group exhibited the minimal chin height and curvature,maximal chin depth/ height ratio and concavity,and the average angle group exhibited the minimal chin angle. Conclusion Chin morphology is different in adolescents with Angle class Ⅱ1 malocclusion by mandibular retrusion in different vertical facial types,which should be taken in to consideration in orthodontics treatment.关键词
