摘要/Abstract

摘要：

目的研究垂直生长型安氏Ⅱ类1分类拔牙病例软组织在矫治前后的变化，以期为正畸临床治疗方案的制定和治疗方法提供参考。方法选择38例垂直生长型安氏Ⅱ类1分类拔牙病例，在矫治前及矫治后拍摄头颅侧位片，对26个测量指标进行测量，并对矫治前后的变化和青少年与成人矫治前后的变化量进行比较。结果矫治后TUL-EP、TLL-EP、上下唇位置、Stoms-Stomi、U1-Ptm等减小，而上唇凹点厚度、上唇凸缘厚度、上下唇长度、上下唇倾角、鼻唇角、Z角、颏唇沟倾角等增加；青少年组上唇凹点厚度、下唇长度、A′-Ptm治疗后均增加，而成人组则减小，差异有统计学意义；同时青少年组与成人组上唇长度、颏唇沟倾角、U1-Ptm的变化也有统计学意义。结论垂直生长型安氏Ⅱ类1分类拔牙病例在早期治疗更能改善侧貌美观。

Abstract:

Objective This study is to evaluate the soft tissue change of Angle′s Class Ⅱ division 1 malocclusion patients with vertical growth pattern after tooth extraction orthodontic treatment, and to provide experimental results to help to make orthodontic treatment plan and treatments. Methods 38 Angle′s Class Ⅱ division 1 malocclusion patients with vertical growth pattern and with tooth extraction orthodontic treatment were included in this study. The pre- and post-treatment cephalometric X-rays were made and 26 measurement items were measured. The change value of pre- and post-treatment, youngsters and adults were compared. Results TUL-EP, TLL-EP, upper and lower lip position, Stoms-Stomi, U1-Ptm were reduced after treatment. Upper lip sulcus and flange thickness, upper and lower lip length, upper and lower lip inclination angle, nasolabial angle, Z angle, mentolabial sulcus inclination angle were enlarged after treatment. The upper lip sulcus thickness, lower lip length and A′-Ptm of adolescent were enlarged, but adult were on the contrary. The change of upper lip length, mentolabial sulcus inclination angle and U1- Ptm between adolescent and adult was statistically different. Conclusion The best treatment period of patients with Angle′s Class Ⅱ division 1 malocculsion with vertical growth pattern was in the rapid growth and development period of adolescent.
