摘要:
[摘要]目的：从牙颌面软硬组织变化，评价拔牙掩饰性矫治对高角骨性Ⅲ类错牙合的治疗效果。方法：选取符合纳入标准
的15例高角骨性Ⅲ类错牙合患者，对其治疗前后的头颅侧位片进行测量分析，比较矫治骨性、牙性和软组织共20项测量指
标的变化，采用配对t 检验分析。结果：治疗后下切牙内收，L1/MP减小（-5.27±2.86）°；上下磨牙直立，U6/PP变化
（-2.92±2.95）°；L6/MP变化（-7.59±4.44）°；下颌平面角维持；软组织面凸角增加（3.76±2.98）°，下唇到E线和
H线距离都减小，LL-E减小（-1.67±2.25）mm，LL-H减小（-0.72±0.30）mm，改变均有统计学意义。结论：拔双尖牙掩饰
性矫治轻中度骨性高角Ⅲ类错牙合后，牙齿咬合和软组织侧貌改善，矫治过程要注意控制切牙和磨牙的垂直方向移动。

Abstract:
Abstract: Objective The aim of this study was to evaluate the clinical effect of the orthodontic camouflage treatment after
extracting bicuspids in skeletal Class Ⅲ high-angle malocclusions. Methods Fifteen patients with skeletal Class Ⅲ highangle
malocclusion who met the including criteria were included in this retrospective study. We measured lateral cephalometric
radiographs before and after the treatment, compared the changes of 20 measurement indexes including bone, teeth and soft
tissue in patients with skeletal Class Ⅲ high-angle malocclusion. Paired t-tests were used in statistical analysis. Results After the
treatment with extracting bicuspids, L1/MP decreased by（-5.27±2.86）°,U6/PP decreased by（-2.92±2.95）°, L6/MP decreased by
(-7.59±4.44）° (P＜0.01), LL-E decreased by(-1.67±2.25）mm, LL-H decreased by (-0.72±0.30)mm, and Ns-Sn-Pos increased by
（3.76±2.98）° (P＜0.01). Conclusion The clinical effect of the orthodontic treatment after extracting premolars in skeletal Class Ⅲ
high-angle malocclusions is satisfactory. But we should pay attention to control the vertical movement of incisors and molars.
