摘　　要：目的评价不同垂直骨面型的青少年骨性Ⅲ类错正畸治疗疗效差异。方法收集青少年骨性Ⅲ类错患者42例,根据不同骨面型分为3组,通过头影测量分析比较各组患者治疗前后骨骼与软组织改变,探讨不同垂直骨面型患者错畸形面部改善疗效的差异。结果 3组患者凹陷的软组织侧貌均得到改善。高角患者主要通过下颌骨顺时针旋转、平面逆时针旋转及上前牙唇倾、下前牙舌倾代偿来实现前牙反的解除,而低角患者更多依赖上前牙唇倾及上颌骨的发育来实现。均角患者其面部比例及颌骨关系相对正常,矫治后主要变化为牙齿的相对移动。结论不同垂直骨面型青少年骨性Ⅲ类错正畸疗效不尽相同;高角型患者在选择采取单纯正畸治疗时需更加谨慎。Objective To evaluate the treatment outcomes among different vertical facial skeletal types in adolescences with skeletal Class Ⅲ malocclusion . Method A total of 42 skeletal Class Ⅲ adoles-cences treated by orthodontic treatment were collected and were divided into three groups according to dif-ferent vertical facial skeletal types . The cephalometric measurements before and after treatment were an-alyzed by indepent-samples t-test when homogeneity of variance . Otherwise ,when heterogeneity of vari-ance ,Satterthwaite t-test was used . Results All of the three groups effectively ameliorated the skeletalⅢ deformity . Patients with high angle corrected the crossbite by clockwise rotation of the mandibles ,an-ticlockwise rotation of the occlusion planes and the teeth compensation ,while low angle patients more de-pended on upper anterior teeth protrusion and the forward growth of the maxillary . The change of the normal angle patients were the teeth relative movement . Conclusion The treatment outcomes were not the same among adolescences with skeletal Class Ⅲ malocclusion by normal orthodontic treatment .
