摘要:

提要:骨性Ⅲ类错牙合的正畸-正颌联合治疗是临床中比较复杂的情况之一。正畸-正颌联合治疗一般包括术前正畸、正颌手术及术后正畸3个阶段:排齐上下牙列,去除牙代偿,协调上下颌牙弓;采用颏成形术、单颌或双颌手术后退下颌骨或(和)前移上颌骨,改善侧貌美观;术后精细调整,形成良好咬合关系。治疗应根据患者颌骨畸形的严重程度、上下唇形态、颏部位置、牙列拥挤度、牙齿倾斜度等畸形特征,具体分析,严格把握适应证,对于边缘病例尤应重视。矫治过程中,应重视术前正畸和手术设计,为正颌手术提供便利。

Abstract:

Summary:Orthodontic-surgical treatment of severe skeletal Class Ⅲ malocclusion is one of the most complicated situations. It usually includes three stages: presurgical orthodontics, orthognathic operation, and postsurgical orthodontics. After aligning, leveling, decompensation of maxillary and mandibular incisors, coordination of dental arches, genioplaty,single-jaw mandibular surgery or bimaxillary surgery will be done to improve the profile esthetics. Intense adjustment in postsurgical orthodontics is for better occlusion. The treatment planning should be based on the severity of the skeletal deformity, morphology of upper and lower lips, position of the chin, severity of crowding, incisor labiolingual inclination, et al. Attention should always be paid to presurgical orthodontics and pre-operative design in consideration of the most acceptable result of the entire treatment.
