摘　　要：目的探讨CBCT研究下颌低位阻生第三磨牙拔除术相关解剖应用。方法对65例(84侧)拟行下颌低位阻生第三磨牙患者CBCT影像学资料进行回顾性分析,与全口曲面断层片比较并作相关统计学分析。结果经对比分析下颌低位阻生第三磨牙CBCT和全口曲面断层片后,对于相关解剖应用及风险的评估二者均具有统计学差异(P<0.05)。结论CBCT相较于全口曲面断层片能更精准更全面地分析下颌低位阻生第三磨牙解剖位置与评估手术风险。Objective To study the clinical anatomy and risk factors of extraction of lower impacted mandibular third molar applying CBCT.Methods 65 cases(84 sides)prepared to extraction of lower impacted mandibular third molar were chosen to analyze retrospectively by CBCT images comparing with orthopantomography.Results There were significant differences in the clinical anatomy and risk factors of extraction of lower impacted mandibular third molar between CBCT and orthopantomography(P<0.05).Conclusion CBCT can be a more accurate and comprehensive method to analyze the positon of lower impacted mandibular third molar,and to evaluate the risk of surgery comparing orthopantomography.
