摘　　要：目的 :建立人类下颌第二前磨牙、第一磨牙、第二磨牙及其支持组织的三维有限元模型 .方法 :利用螺旋CT扫描的方法 ,采用图像处理和有限元分析软件建立 5 6 7及其支持组织的三维有限元模型 .结果 :建立了包括了牙体、牙周膜、松质骨、皮质骨等组织三维有限元模型 ,受力分析结果与临床实际相符 .结论 :采用有限元方法建模 ,是一种简洁、有效。AIM: To establish a 3 D finite element model of human mandibular molars. METHODS: A 3 D finite element model of human mandibular molars,[BHDWG*2,WK1,K1*3/4W]567, and their supporting tissues was established by means of SCT scanning, image processing software and finite element analyzing program. RESULTS: A 3 D finite element model of [BHDWG*2,WK1,K1*3/4W]567, including enamel, dentin, cementum, cortical bone, sponge bone, pulp and mucosa was established. The stress analysis showed that it was consistent to that observed in clinical practice. CONCLUSIONS: To establish models by finite element method is simple, effective, safe and reliable.
