A 19-year-old woman with skeletal Class III malocclusion, paranasal depression, and a low mandibular plane angle was treated with orthodontics and orthognathic surgery. Dental decompensation and protraction of maxillary right third molar to replace maxillary right second molar were performed before surgery. Clockwise rotation of maxillo-mandibular complex was applied by Le Fort I osteotomy and bilateral sagittal split osteotomies to achieve facial balance. The active treatment period was 12 months. The stable occlusion and skeletal relationship were observed after a 10-month follow-up period.
一位 19 岁的女性患者,存在骨骼 III 类错颌、面中凹陷和低下颌平面角,接受了正畸和正颌手术治疗。术前进行了牙齿代偿性移位和上颌右侧第三磨牙的远中牵引以替代上颌右侧第二磨牙。通过 Le Fort I 截骨术和双侧矢状劈开截骨术使上颌-下颌复合体顺时针旋转,以达到面部平衡。主动治疗期为 12 个月。在 10 个月的随访期后,观察到稳定的咬合和骨骼关系。
