目的：应用锥形束CT（CBCT）对牙槽突裂植骨术后进行三维结构定量分析并探讨牙槽裂移植骨吸收的特点。方法：35例患者均在术后1周、1月、3月、6月、12月进行CBCT扫描，对牙槽突裂移植骨体积三维方向分割测量，并计算移植骨量比率。结果：移植骨量比率在牙槽嵴顶，鼻底以及腭侧部位减少较为明显。骨吸收主要发生在术后3月，术后6月基本稳定。结论：CBCT及其相关软件分析可对移植骨的三维结构进行精确的定位定量分析。

Objective:To analyze the quantitative and location postoperative of ABG with the application of CBCT in three-dimensional direction, and explore the the absorption of ABG. Method:35patients had undergone CBCT scan in postoperative one week,three months,six months,twelve months and measured cleft alveolar or bone-grafted. Calculate ratio of bone-grafted. Result:The absorption of the grafted bone was in nose base,palatal side and the alveolar ridge. The absorption of postoperative ABG occurred mainly in the first 3 months. The bone was in a stable period in postoperative 6 months. Conclusion
