This case report describes the treatment of a 16-year-old girl with a unilateral posterior buccal crossbite, a unilateral Class II molar relationship, and a maxillary right canine high in the labial sulcus. The treatment plan included surgically assisted unilateral maxillary expansion for the correction of the buccal crossbite, with simultaneous dentoalveolar distraction of the maxillary right canine into the extraction space of the first premolar aided by skeletal anchorage. Reduced orthodontic treatment time was facilitated by these 2 surgical procedures. A pleasing esthetic result and a good functional occlusion were achieved in 13 months.
本病例报告描述了一位 16 岁女孩的治疗过程，她存在单侧后颊侧错位、单侧 II 类磨牙关系和上颌右侧尖牙唇侧高位。治疗计划包括手术辅助上颌单侧扩展以矫正颊侧错位，同时利用骨锚辅助上颌右侧尖牙的牙牙槽骨牵张进入第一前磨牙的拔牙间隙。这两个手术有助于缩短正畸治疗时间。在 13 个月内获得了满意的美观效果和良好的功能咬合。
