目的：??通过锥形束CT（CBCT）影像评估上牙槽后动脉骨孔位置、大小及与剩余牙槽骨的关系。方法??选择2011年4月—2012年9月前来南昌大学附属口腔医院种植科要求行上颌窦底提升手术和(或)上颌磨牙区种植手术，并且拍摄CBCT的患者116名，测量记录其上牙槽后动脉骨孔下缘至剩余牙槽嵴顶间距、上牙槽后动脉骨孔直径、剩余牙槽嵴高度，对各测量值进行统计分析。结果??入选116名患者中上牙槽后动脉骨孔的发现率为75.14%（133/177）；骨孔的平均直径为（0.96±0.29）?mm；剩余牙槽嵴高度平均值为（7.14±3.64）?mm；上牙槽后动脉骨孔下缘距剩余牙槽嵴顶间距均值为（17.92±5.68）?mm。经采用独立样本t检验发现性别对骨孔直径影响差异有统计学意义（F=0.187，P<0.05）；右侧和左侧骨孔间差异无统计学意义（F=0.295，P>0.05）。上牙槽后动脉骨孔下缘距牙槽嵴顶间距与剩余牙槽嵴高度显著正相关。结论??CBCT在发现上牙槽后动脉骨孔具有较明显的优势。
