摘　　要：目的:分析微种植支抗前牵引矫治儿童恒牙列早期骨性Ⅲ类错治疗前后软硬组织变化的侧貌美学相关性。方法:纳入11~13岁骨性Ⅲ类前牙反患儿20例(男12例,女8例),采用微种植支抗前牵引矫治8~10个月,治疗前后拍摄曲面断层片和头颅定位侧位片,测量软硬组织相关指数,对治疗前后患者的治疗效果进行分析。结果: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变化,观察1年后矫治效果稳定。结论:微种植支抗前牵引矫治能够促进上颌骨向前生长,改善骨性Ⅲ类错患者的软组织侧貌,使前牙建立正常的覆覆盖关系。Objective：To evaluate the profile esthetics of children with skeletal class Ⅲ malocclusion treated with micro-implant.Methods：20 patients （12 boys and 8girls） aged 11-13 years were treated by micro-implant and maxillary protraction for 8 to 10 months.The profile esthetic indexes were measured on pre-and post-treatment cephalometric radiography.Results：The esthetic of the patients were remarkably improved after treatment.The factors that influence the esthetic index of children were the anteroposterior relationship of the maxilla,the mandible and the thickness of soft tissue.The results were stable 1 year after treatment.Conclusion：Maxillary protraction by micro-implant can improve the profile esthetic of children with Class Ⅲ malocclusion,correct over-bite and over-jet.
