摘　　要：目的 探讨尖牙已萌出的双侧腭裂患者牙槽突植骨术前正畸的临床效果.方法 收集双侧腭裂患者,其中双侧恒尖牙已完全萌出的25例（试验组）;双侧尖牙皆未萌出的56例（对照组）.对患者做术前正畸治疗,之后行牙槽突植骨术.术后6个月拍摄全景片和上颌前部的咬合片,采用Bergland标准评价植骨效果.Ⅰ型、Ⅱ型为植骨成功,Ⅲ型、Ⅳ型为植骨失败.对术后X线片做测量分析,并据此判定植骨的分型.结果 植骨术后试验组Ⅰ型、Ⅱ型20例,成功率为80.0％;对照组Ⅰ型、Ⅱ型53例,成功率为94.6％,两组差异有统计学意义（P＜0.05）.在植骨成功的患者中,试验组Ⅰ型12例,占总成功例数60.0％,对照组Ⅰ型48例,占总成功例数90.6％,两组差异有统计学意义（P＜0.01）.在植骨失败的患者中,试验组Ⅳ型4例,占总失败例数的80.0％,对照组Ⅳ型0例,两组差异有统计学意义（P＜0.05）.结论 对于尖牙已完全萌出的双侧腭裂患者,通过适当的、认真细致的术前正畸和牙槽突植骨术治疗,可取得比较好的效果.Objective To study the clinical effect of orthodontic treatment in patients with bilateral completely cleft palate and completely erupted canines before alveolar bone graft.Methods Patients were divided into two groups：test group included patients with bilateral completely cleft palate and completely erupted canines;and control group included patients with bilateral cleft palate whose canine had not erupted.Orthodontic treatment was performed before surgical bone graft operation.X-ray morphometry was performed 6 months after surgical procedure.Bergland standard was used to estimate the clinical effect of bone graft.Types Ⅰ and Ⅱ were considered as success and Types Ⅲ and Ⅳ as failure.X-ray analysis was performed in each patient.Results The test group included 25 patients and control group 56 patients.The number of Types Ⅰ and Ⅱ in the test group was 20,with successful rate of 80%.The number of Types Ⅰ and Ⅱ in control group was 53,with successful rate of 94.6%.There was a statistical difference between two groups （P〈0.05）.In the test group,the number of Type Ⅰ was 12,about 60% of all successful cases.In control group,the number of Type Ⅰ was 48,about 90.6 % of all successful cases.There was significantly statistical difference between two groups （P〈0.01）.In the test group,the number of Type Ⅳ was 4,about 80% of all fail cases.In control group,no Type Ⅳ happened.There was also a statistical difference between two groups （P〈0.05）.Conclusions Orthodontic treatment and surgical bone graft can be done successfully in older patients with bilateral cleft palate and completely erupted canines.
