摘　　要：目的:探讨安氏Ⅱ1类错不同垂直骨面型患者软组织的侧貌特征。方法:随机选取安氏Ⅱ1类错牙合低角型、均角型、高角型女性成年患者各28例,共84例,年龄18～23岁,平均20.3岁。选取矫治前X线头颅侧位片,进行头影测量,采用SPSS12.0统计软件包进行单因素方差分析和独立样本t检验。结果:一系列指标随着面高的增加呈现出有规律的变化趋势。侧貌突度及上、下唇突度依次明显增大,而面下部深度逐渐由过深变浅,同时上下唇弧的弧度由大变小、弧形由深变浅、由过于弯曲趋于过直立,尤其是低角组颏唇沟过凹陷而高角组过平坦。结论:垂直骨面型对安氏Ⅱ1类错牙合的软组织侧貌特征尤其是唇颏部形态有着显著影响。PURPOSE： To investigate the difference of the facial soft tissue profile on Angle Class Ⅱ^1 malocclusion with various vertical growth pattern. METHODS： The samples （n=84） were divided into three groups （low-angle, medial-angle, high-angle group） based on their SN-MP angle.Their cephalograms were measured and all data were analyzed by SPSS12.0 software. RESULTS： There were some regular changes in most facial profile variables while the mandibular plane angle increased： the facial profile convexity and the upper- and lower-lip convexity increased significantly; the depth of anterior lower face decreased from too large to small; the radian of upper- and lower- lip curve changed from too winding to upright. CONCLUSION： Vertical growth patterns make significant differences to soft tissue facial profile on Angle Class Ⅱ^1 malocclusion.
