摘　　要：目的:评价异种骨移植同期牙种植修复单个牙缺失伴唇(颊)侧水平型骨缺损的临床效果,并应用锥形束CT观察不同时期骨移植材料的成骨情况。方法:对2010年1月—2012年6月牙列缺损的10例患者行异种骨移植,同期植入14颗种植体。术后即刻、3个月、6个月分别进行锥形束CT扫描,应用CT自带的KaVo eXam Vision软件观察种植体周围骨密度,测量种植体唇(颊)侧不同位点的牙槽嵴厚度,采用SPSS17.0软件包对符合正态分布的数据进行t检验,评估异种骨移植材料的成骨效果。结果:随体内存留时间的延长,异种骨移植材料成骨效果的变化差异具有显著性(P<0.05)。结论:异种骨移植同期牙种植修复缺失牙的临床效果可以通过锥形束CT进行评估,异种骨移植材料在水平型单壁骨缺损的修复中具有良好的成骨效果。PURPOSE： To evaluate the clinical outcome and osteogenesis of simultaneous endosseous implant placements with xenographic bone grafts in horizontal bone defect. METHODS： Ten patients underwent simultaneous endosseous implant placements with xenographic bone grafts from January, 2010 to June, 2012. These patients were scanned by conebeam computed tomography immediately, 3 months and 6 months after operation, respectively. The alveolar ridge thickness were measured in different sites, and the data with normal distribution was analyzed with SPSS17.0 software package. RESULTS： With increase of xenographic bone graft retention time, the difference of osteogenesis of xenographic bone grafts was significantly different （P〈0.05）. CONCLUSIONS： Cone-beam computed tomography ean clearly determine the clinical outcome and osteogenesis of simultaneous endosseous implant placements with xenographic bone grafts in horizontal bone defect, which is characterized by good ossification.
