摘要 36岁女性患者,因"反颌、面部偏斜、牙齿不整齐20余年"就诊。与患者沟通正畸-正颌治疗方案,但患者要求行代偿性正畸治疗。接受正畸代偿性治疗过程中,解除了前牙反[牙合],但牙槽骨吸收逐渐加重,出现咬合不适症状,上前牙唇倾明显,牙龈退缩明显,后牙开[牙合]。经过正颌手术获得了良好的术后效果。正颌手术采取上颌骨LefortⅠ型截骨术,同期进行"π"型截骨将上颌骨分成3个部分,将上颌前牙区顺时针旋转,调整上颌前牙牙轴方向,调整两侧上颌后牙区宽度及方向,以与下颌牙列宽度相匹配。同期下颌行双侧矢状劈开截骨后退术;术后佩戴终末咬合导板2个月,行双侧Ⅲ类颌间弹性牵引,维持上下牙咬合关系。正畸正颌治疗结束2年时复查,牙齿排列整齐,咬合关系正常,牙周情况良好,患者对治疗效果满意。
