The following research results were obtained :Secondary bone graft for alveolar cleft were performed by using autogenious bone(PCBM) and allograft(demineralized freeze-dried bone from tissue bank). After 1 year follow up both materials were evaluated clinically and radilgraphically and pathologically.As a result, 1. clinically both grafted materials showed excellent healing condition and by occlusal and dental radiographic examination. 2. By observing 3 dimentional CT, cleft area was filled with new bone which came from graft materials. 3. By performing bone biopsy pathologically new bone was formed around allograft and showed ability of the grafted bone to conduct new bone formation and PCBM showed multiple bone formation after l year.From these results it is confirmed that both materials are useful as graft material for the alveolar cleft.

获得了以下研究结果：使用自动骨（PCBM）和同种异体移植（来自组织库的脱矿质冻干骨）进行肺泡裂缝的次级骨移植。 1年后跟进后，两种材料在临床和放射性和病理上进行了评估。结果，1。临床上移植的材料均显示出极好的愈合状况以及咬合和牙科射线照相检查。 2。通过观察3尺寸的CT，裂缝区域充满了来自移植物材料的新骨。 3。通过在同种异体移植周围形成病理学上的骨活检，并显示移植骨进行新骨形成的能力，而PCBM在L年后显示出多个骨形成。从这些结果中可以证实，这两种材料都是肺泡裂口的移植物材料。
