摘　　要：目的本研究是确定多排螺CT三维重建测量下颌骨的准确性,为临床牙槽外科术前诊断提供了可靠的技术保障。方法对5例成人正常干躁下颌骨标本,进行实体及螺旋CT三维重建后测量,然后对两种方法所得数据进行统计学分析。结果牙槽嵴顶由前向后逐渐增宽,牙槽嵴由上向下逐渐增宽;下颌骨神经管全长总体走行紧邻舌侧骨板。结论三维螺旋CT重建测量与实体解剖测量所得各项数据经统计学处理无显著性差异。Objective The aim of this study was to determine the reliability of the mandibular bone by three dimension reconstruction of multiple spiral CT.Methods 5 case dried mandibular bones with teeth are chosen,and a three-dimensional model was measured with the method of spiral CT,The same work was done to the bone specimen,and then comparative analysis was done.Results The wideness of the alveoli increased from mesial to distal position.It was the same of the alveoli from the top to the bottom.The mandibular canal lied in the inner and inferior side of the mandibular body.Conclusion There was no significant difference in data collected with these two methods.
