The treatment of an 8-year-old girl with a dilacerated maxillary incisor began in the mixed dentition; a modified palatal arch attached to the molars served as anchorage for the forced eruption of the dilacerated tooth to prevent the intrusion of the adjacent teeth and reduce the risk of root resorption. Two surgical sessions were planned: the first to permit the closed eruption; the second was an apically positioned flap to add attached gingiva to the labial side of the erupting tooth. The result was an optimal periodontal outcome; moreover, the roots of the adjacent teeth did not show any sign of resorption at the end of the forced eruption. The tooth was vital at the end of the treatment, and the apex covered by alveolar mucosa. The root developed normally throughout the treatment, and the periodontium was healthy and esthetically acceptable at the 2-year follow-up. Further study is needed to assess the advantages of the combined surgical-orthodontic treatment.
一位 8 岁女孩的上颌侧切牙扭转的治疗始于混合牙列期；改良腭弓附于磨牙上，作为倾斜牙的强迫萌出的支抗，以防止邻牙的内陷和减少牙根吸收的风险。计划进行两次手术：第一次是为了实现封闭性萌出；第二次是根尖定位瓣，以增加萌出牙唇侧的附着龈。结果牙周状况良好；此外，在强迫萌出结束时，邻牙的牙根没有任何吸收的迹象。治疗结束时牙齿有活力，根尖被牙槽黏膜覆盖。在整个治疗过程中，牙根正常发育，牙周组织健康，在 2 年的随访中美观可接受。需要进一步研究来评估联合手术-正畸治疗的优势。
