牙槽骨牵引成骨治疗先天性双侧重度牙槽突裂1例报告

牙槽突裂的常规治疗方法为髂骨骨松质植骨术。普遍认为,牙槽突裂隙较宽者,黏膜瓣转移、缝合及血运重建困难,植骨术成功率较低。牙槽骨牵引成骨能够有效关闭或缩窄较宽的牙槽突裂,提高植骨效果。本文报告1例牙槽骨牵引成骨治疗先天性双侧重度牙槽突裂病例,截骨线设置在裂隙近中,以种植钉和后牙作为支抗,皮链牵引骨块向后,在缩窄牙槽突裂的同时,上颌骨前突减轻。

A case report of alveolar bone distraction osteogenesis in congenital bilateral severe alveolar cleft deformity

The conventional treatment for alveolar cleft is cancellous iliac bone grafting.However it is difficult to transfer and suture mucosal flaps and reconstruct blood supply in patients with wide alveolar cleft,and the success rate of bone grafts is lower.Alveolar bone distraction osteogenesis can effectively close or narrow the wide alveolar cleft,which is beneficial to improve the effect of bone grafting.This article reported a case of alveolar bone distraction osteogenesis for the treatment of congenital bilateral severe alveolar cleft.The osteotomy line we placed in the mesial aspect of the cleft and micro-implants and posterior teeth were used as anchorage,and power chains were applied to pull the bone back,narrowing the alveolar cleft and ameliorating the maxillary protrusion at the same time.
