The primary purpose of this study was to evaluate presurgical status of the alveolar cleft site and success of secondary alveolar bone grafting.
Thirty patient records were retrospectively reviewed. Patients selected for inclusion had isolated cleft of at least the primary palate. Patients with additional anomalies were not selected. The study population consisted of 15 female sites and 16 male cleft sites. There were two bilateral cleft lip and palate (CLP) patients and 28 unilateral CLP patients. The age at the time of the secondary alveolar bone grafting ranged from 7 years to 14 years, 4 months.
The study was conducted at the Cleft Palate Clinic at the University of Minnesota, School of Dentistry.
Presurgical radiographs taken at least 1 month prior to the secondary bone grafting and postsurgical radiographs taken at least 6 months after bone surgery were measured. Measurements included size of the cleft defect and bone support for distal and mesial teeth adjacent to the cleft. Evaluation of success was determined on the basis of postsurgical measurements of satisfactory, intermediate, and unsatisfactory outcomes.
The size of the cleft defect was not correlated with the success rate of the secondary alveolar bone grafting. If the amount of distal bone support for the mesial tooth was the same as those in a periodontally healthy individual, a satisfactory outcome was 5.8 times more likely. If the amount of mesial bone support for the distal tooth was the same as those in a periodontally healthy individual, the satisfactory outcome was 3.8 times more likely. Although not a primary purpose of the study, it was found that in this study population, if the patient was female, a satisfactory outcome was 3.8 times more likely.
本研究的主要目的是评估牙槽嵴裂部位的术前状况以及二期牙槽骨移植的成功率。
对30例患者的记录进行回顾性分析。入选患者至少有原发腭部孤立性腭裂。未选择有其他异常的患者。研究对象包括15个女性腭裂部位和16个男性腭裂部位。有2例双侧唇腭裂（CLP）患者和28例单侧CLP患者。二期牙槽骨移植时的年龄范围为7岁至14岁4个月。
本研究在明尼苏达大学牙科学院腭裂诊所进行。
测量二期骨移植术前至少1个月拍摄的X光片以及骨手术后至少6个月拍摄的术后X光片。测量内容包括腭裂缺损大小以及腭裂相邻近中牙和远中牙的骨支持情况。根据术后测量结果将成功情况评估为满意、中等和不满意。
腭裂缺损大小与二期牙槽骨移植成功率无关。如果近中牙远中骨支持量与牙周健康个体相同，获得满意结果的可能性高出5.8倍。如果远中牙近中骨支持量与牙周健康个体相同，获得满意结果的可能性高出3.8倍。虽然这并非本研究的主要目的，但发现在本研究对象中，如果患者为女性，获得满意结果的可能性高出3.8倍。
