摘　　要：目的探讨术前正畸联合术中应用可吸收胶原生物膜对单侧牙槽突裂植骨效果的影响。方法选择牙弓狭窄、上颌前牙舌倾或扭转、牙槽突裂隙不规则、难以进行牙槽突裂植骨术的单侧完全性牙槽突裂患者30例,年龄9～13岁,先进行植骨前正畸治疗,再应用髂骨松质骨加可吸收胶原生物膜覆盖行植骨修复,术后定期拍X线片检查,观察植骨效果。牙槽骨高度评价标准采用Bergland标准进行,术后观察期为1～3年。结果 30例患者术后成骨情况Ⅰ型11例,Ⅱ型17例,植骨成功率达93.3%。结论对于上颌牙弓狭窄、牙槽突裂隙不规则、牙颌畸形严重的牙槽突裂患者,建议先行植骨前正畸治疗,植骨术中联合应用可吸收胶原生物膜可有效提高植骨成功率。Objective To discuss the effect of bone grafting in patients with unilateral alveolar deft, treated by pre- surgical orthodontics and secondary alveolar bone grafting surgery with absorbable collagen bio-membrane, in order to im- prove the success rate of graft. Methods Thirty complete unilateral alveolar cleft patients, aged 9 - 13 years, with col- lapsed upper arch or severe malpositioned upper incisors were selected. The patients received pre-surgical orthodontics before secondary alveolar bone grafting used ilium and absorbable bio-membrane. The observation period was I -3 years and X-ray was taken regularly. Bergland criteria were used to evaluate the alveolar bone height. Results Pre-surgical orthodontics expanded the collapsed upper arch to benefit the secondary alveolar bone grafting with absorbable collagen bio-membrane, and the success rate of graft was improved to 93.3 %. Conclusion It is worth popularizing that patients with collapsed upper arch or severe real-positioned upper incisors should receive pre-surgical orthodontics and then sec- ondary alveolar bone graft surgery with absorbable collagen bio-membrane.
