摘　　要：目的分析安氏Ⅲ类错[牙合]面部软组织侧貌与切牙位置之间的相互关系，为临床正畸治疗提供理论依据。方法对26例安氏Ⅲ类错[牙合]患者矫治前后X线头影测量片进行分析，包括测量19个硬组织项目和6个软组织项目，用统计软件SASv8．0分析矫治前后面部软组织与切牙倾斜度的变化及相关关系。结果上下切牙倾斜度对侧貌美学指标均有相关性。结论安氏Ⅲ类错[牙合]通过增加上切牙的倾斜度，减少下切牙的倾斜度可使侧貌协调，上下切牙位置关系影响软组织协调性。Objective To assess the relationship between position of incisor and soft tissues changes in class Ⅲ malocclusion cases after orthodontic treatment. Methods All 26 patients in this study were diagnosed as skeletal class Ⅲ malocclusion. The lateral X-ray cephalometric films taken at the beginning and the end of the treatment were analyzed for position of incisor and soft tissues changes. Statistical analysis was performed using SAS v8. 0 software. Results There was correlation between the labial inclination of upper and lower incisots and the soft tissue profile. Conclusion Soft tissue will be harmonious by the labial inclination increase of the upper incisor teeth and reduction of the lower incisor teeth.
