摘　　要：１６例单侧唇腭裂伴牙槽裂和１例双侧唇腭裂伴牙槽裂患者，用下颌正中联合区骨移植修复牙槽裂，术后随访时间平均１８个月。术后６个月，咬合Ｘ线片证明移植骨完全愈合，再造牙槽突的形态满意且无牙周并发症。手术后６个月Ｘ线片见供区愈合。下颌骨正中联合区骨移植有并发症少，住院时间短，手术时间短而且可避免供区瘢痕等优点。本研究结果表明下颌正中联合区骨可用作为整复牙槽裂的供区。This study evaluated the effect of mandibular symphysis bone grafts for reconstruction of alveolar clefts. The study included 16 patients with unilateral cleft lip and palate and alveolar process only and one patient with bilateral cleft lip and palate, with a median postoperative follow up of 18 months (range, 6 to 36 months). The bone grafts were obtained from below the mandibular incisors and canines through an intraoral approach. The marginal bone level achieved was satisfactory in all cases evaluated by occlusal radiographs; the radiographs also demonstrated that the bone grafts were completely integrated after 6 months in all cases. The morphology of the reconstructed alveolar process was satisfactory in all cases evaluated and no periodontal complications were seen. The donor site appeared healed radiologically in all cases 6 months after surgery. The advantages gained by using a mandibular bone graft as compared to an iliac crest graft include reduced morbidity, reduced hospitalization time, reduced operating time, and aviodance of scarring at the donor site. The results of the present study demonstrate that the mandibular symphysis can be used as donor site for reconstruction of alveolar clefts.
