Patients with bimaxillary protrusion may have an unattractive profile with a retruded chin contour. Correction of the severely protrusive anterior alveolar bone and teeth combined with a moderate open bite without orthognathic surgery can be challenging. This case report describes the orthodontic treatment of a woman with severe bimaxillary protrusion and a moderate open bite. Excellent chin morphology and facial appearance were obtained with the extraction of 4 first premolars and 4 third molars, and total distalization of both arches with 4 mini-implants, one in each quadrant between the second premolar and the first molar. The total treatment time was 30 months.
双颌前突患者可能有下巴轮廓后缩的不美观侧面轮廓。在不进行正颌手术的情况下，矫正严重前突的前牙槽骨和牙齿并伴有中度开牙合具有挑战性。本病例报告描述了一名患有严重双颌前突和中度开牙合女性的正畸治疗。通过拔除4颗第一前磨牙和4颗第三磨牙，并使用4颗微型种植体（每个象限在第二前磨牙和第一磨牙之间各植入一颗）对上下牙弓进行整体远中移动，获得了良好的下巴形态和面部外观。总治疗时间为30个月。
