Abstract

This article describes the surgical orthodontic treatment of maxillary hypoplasia in a patient with cleft lip and palate using maxillary distraction osteogenesis with internal maxillary distractors. Maxillary advancement was performed to correct the retrusive maxillary facial profile and Class III malocclusion. Rotational movement of the distraction segment was made to correct the upper dental midline. Although maxillary advancement was insufficient because of unexpected breakage of the intraoral distractor after completion of the distraction, skeletal traction with a face mask compensated for the shortage. Successful esthetic improvement and posttreatment occlusal stability were achieved with no discernible relapse after 2 years of retention.

摘要

本文描述了一例唇腭裂患者上颌骨发育不全的外科正畸治疗,采用内置式上颌骨牵引器行上颌骨牵引成骨术。上颌骨前徙术用于矫正上颌后缩的面型和 III 类错颌。通过旋转牵引骨段来矫正上颌牙中线。尽管由于牵引器在完成牵引后意外折断,导致上颌前徙量不足,但通过使用面弓进行骨牵引进行了补充。在 2 年的保持期后,患者的面型美观得到了明显改善,且咬合稳定,无明显复发。
