The purpose of the study was to evaluate radiologically the efficacy of guided bone regeneration using composite bone graft (autogenous bone graft and anorganic bovine bone graft [Bio-Oss]) along with resorbable collagen membrane (BioMend Extend) in the augmentation of Seibert's class I ridge defects in maxilla. Bone width was evaluated using computerized tomography at day 0 and at day 180 at 2 mm, 4 mm, and 6 mm from the crest. There was a statistically significant increase in bone width between day 0 and day 180 at 2 mm, 4 mm, and 6 mm from the crest. The results of the study demonstrated an increase in bone width of Seibert's class I ridge defects in the maxilla of the study patients.
本研究的目的是通过放射学方法评估使用复合骨移植材料（自体骨移植和无机牛骨移植材料[Bio-Oss]）联合可吸收胶原膜（BioMend Extend）对上颌骨Seibert I类牙槽嵴缺损进行增量治疗的疗效。在术后第0天和第180天，使用计算机断层扫描在距牙槽嵴顶2毫米、4毫米和6毫米处评估骨宽度。在距牙槽嵴顶2毫米、4毫米和6毫米处，术后第0天和第180天之间的骨宽度有统计学意义的增加。该研究结果表明，研究患者上颌骨Seibert I类牙槽嵴缺损的骨宽度有所增加。
