牙槽突裂骨移植治疗进展

牙槽突裂骨移植是口腔颌面部裂隙畸形重建的重要步骤。初期肋骨移植能使上颌骨连续,消除口鼻腔瘘,不影响面中部发育,有助于防止双侧唇裂上颌骨节段性塌陷。二期髂骨移植成功率高,能稳定地产生小梁骨,恢复上颌骨连续性,提供正畸支持。牙槽突植骨能否产生足够的牙槽骨支持后期的正畸治疗,尚需进一步研究。本文就牙槽突裂骨移植治疗的进展作一综述。

Progress in management of alveolar cleft bone grafting

Bone grafting of the alveolus is an essential step in the reconstruction of the orofacial cleft deformity. Primary grafting with rib results in a unified maxilla, eliminates the oronasal fistula, and does not adversely affect midfacial growth. It assists in preventing maxillary segmental collapse, particularly in the bilateral cleft patient. Secondary grafting with iliac marrow consistently produces trabecular bone to unify the maxilla and provide odontogenic support. It requires preoperative maxillary alignment, well designed mucoperiosteal flaps, and good oral hygiene to be optimally successful. Whether it can produce enough alveolar bone to support long-term odon- togenic needs await further clinical research.
