[Clinical and radiographic evaluation of simultaneous endosseous implant placements with xenographic bone grafts in bone defect by cone-beam computed tomography].

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 cone-beam 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 can 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.
