摘　　要：凹面型是由上颌发育不足或(和)下颌发育过度导致的一种影响美观的侧貌类型。对处于生长期的患者,面弓前牵引辅助上颌交替快速扩弓缩弓是最常用的方法,可以有效促进上颌骨发育;头帽颏兜矫治后易复发,现已不建议使用。对于生长发育已完成的患者,轻中度错可采用掩饰性正畸的方法,特殊的拔牙方式及差动矫治技术可以获得令人满意的效果;若为重度骨性Ⅲ类错则正畸-正颌联合治疗是唯一的解决方案。Concave facial profile,developed by maxillary dysplasia or mandibula hypergenesis,really affect beauty.For growing patients,maxillary protraction therapy with alternate rapid maxillary expansions and constrictions is the most common method,which can promote the development of maxillary effectively.Headgear-chincup is not suggested to use because of relapse.For patients who have completed growth,mild or moderate skeletal ClassⅢmalocclusion could be treated with orthodontic camouflage.Successful treatment effects could be obtained by special tooth extraction mode and differential force orthodontic technique.However,orthodontic-orthognathic treatment is the only method for severe skeletal ClassⅢmalocclusion patients.
