摘　　要：目的:分析上颌前方牵引矫治儿童Class Ⅲ类错治疗前后软组织变化的侧貌美学相关性探讨。方法:选取就诊于我所正畸科8～12岁Class Ⅲ高角型前牙反患儿14例,采用上颌铸造式固定前牵引矫治6～8个月,治疗前后拍摄头颅定位侧位片,对正畸前后侧貌进行美学评价,并对侧貌美学指标的相关性进行探讨。结果:上颌前牵引矫治后患者的软组织侧貌有显著改善,美学测量指标与颌骨的改建以及软组织的厚度有较明显的关系。结论:上颌前牵引矫治对Class Ⅲ类错患者的侧貌美观有明显改善,但对于垂直性骨面型无法改善。Objective To evaluate the profile esthetics of skeletal class III children before and after maxillary protraction and to analyze the influence factors of the profile esthetic index. Methods 14 patients （8 boys and 6 girls） from Oral Disease Preventive Center of LuWan Area shanghai were included in the study. They all used maxillary protraction for 8 to 10 months.Their pre- and posttreatment cephalometric X-rays were measured. Results The esthetic evaluations of these patients were remarkably improved after maxillary protraction. The factors that influence the esthetic index of children are the anteroposterior relationship of the maxilla,the mandible and the thickness of soft tissue. Conclusion Maxillary protraction could improve the profile esthetic of patient with Class III malocclusion, but the vertical growth pattern couldn＇t be improved after treatment.
