摘　　要：目的应用牙三维成像(CBCT)对齿槽嵴裂植骨术后的植入骨位置进行临床评价。方法选取18名单侧完全性齿槽嵴裂患者,在齿槽嵴裂植骨术后3个月对植骨部位进行CBCT扫描,将齿槽嵴裂隙分割后对植入骨的位置进行定位。结果齿槽嵴裂植骨术后,近远中向上植入骨的数量没有统计学差异(P>0.05);唇腭向上唇侧的植入骨数多于腭侧植入骨数(P<0.001);垂直向上,植入骨主要存在于裂隙侧中切牙的根中和根尖1/3,而鼻底及近牙槽嵴顶的植入骨数量较少(P<0.05)。结论齿槽嵴裂植骨术后植入骨的位置主要位于裂隙侧中切牙的根中和根尖1/3处,且唇侧的骨量明显多于腭侧的骨量。Objective Cone beam computed tomography（CBCT）of the teeth is used for the clinical assessment of the bone graft positions after bone grafting at alveolar cleft. Methods For this study, 18 patients with complete alveolar cleft at one side were selected and CBCT was performed at the bone grafting site 3 months afterward. The alveolar cleft crack was fractioned for the identification of the bone graft positions. Results After bone grafting at alveolar cleft,no statistically significant differences（P〉0.05） were identified in the number of bone grafts at the above of the mesiodistal area. The number of bone grafts was higher at the labial area above the labial-palatal area than that of bone grafts at the palatal side（P〈0.001）. Vertically upward, the bone grafts were mainly located at the middle and 1/3 of the top of the root of the side central incisor at the cleft, and there were relatively less bone grafts at the basis nasi and the near alveolar ridge crest area（P〈0.05）. Conclusion The positions of the bone grafts after bone grafting at alveolar cleft are mainly located at the middle and 1/3 of the top of the root of the side central incisor at the cleft and the number at the labial side is significantly higher than that at the palatal side.
