【摘要】 目的　探讨双侧唇腭裂病例牙槽突植骨的远期疗效。方法　 5 5例双侧完全性唇腭裂患者 ,双侧牙槽突植骨手术在GOS儿童医院 (GreatOrmondStreetHospitalforChildren)完成 ,植骨部位共110个。植骨材料选用髂骨松质骨 ,以植骨手术进行时尖牙的萌出情况将裂隙分为 2组。植骨前后拍摄上颌前部咬合片 ,手术后观察时间为 1至 10年。采用Bergland标准评价植骨部位的牙槽骨高度。结果　在尖牙萌出前植骨的成功率 (95 % )明显高于尖牙萌出后植骨者 (6 7% )。结论　影响唇腭裂患者牙槽突植骨成功的因素很多 ,植骨时机是植骨成功与否的重要因素更多还原

【Abstract】 Objective To evaluate the long-term result of the bilateral alveolar bone grafting Methods Fifty-five consecutive complete bilateral cleft lip and palate patients (36 males and 19 females) who had alveolar bone grafting were included in this study The total number of cleft sites was 110 Cancellous bone from the iliac crest was grafted into the alveolar cleft areas The cleft sites were studied in two groups according to whether the cleft canine had erupted prior to bone grafting or not Anterior occlusal radiographs were taken before and after bone grafting The minimum period of observation after alveolar bone grafting was one year Criteria described by Bergland et al (1986) were utilised to assess the height of the interdental septum Results The results showed that bone grafting before canine eruption has a higher clinical success rate (95%) compared with that carried out after canine eruption (67%) Conclusion The critical variable affecting the quality of bilateral alveolar bone grafting is the timing of the surgery更多还原
