先天性牙缺失患者的单纯正畸治疗与正畸-修复联合治疗浅探

Clinical Observation of Orthodontic Treatment and Orthodontic-Prosthodontic Combined Treatment for Congenitally Missing Teeth Patients

目的：探讨先天失牙患者的缺牙特征及单纯正畸或正畸修复联合治疗的临床效果。方法：收集2006~2014年在我科矫治的先天失牙患者24人,拍全口曲面断层片、颞下颌关节开闭口位片及头颅定位侧位片,并根据面型及牙列拥挤度等决定治疗方案,通过正畸治疗将间隙集中后再义齿修复,观察临床疗效。结果：24例先天失牙患者采用上述方法进行治疗,均获得正常覆盖、覆关系,面型协调,软组织侧貌得到改善。结论：先天缺失1~2牙的错畸形,根据面型、错情况、缺牙数目设计不同矫治治疗方案,能够获得满意的矫治效果。多牙先天牙缺失,常需正畸-修复联合治疗才能获得较好疗效。
