桩冠固定修复的生物力学研究

Biomechanical Research on Maxillary Central Incisor Tooth Restoration with Post using Three Dimentional Finite Element Method

本文针对桩冠修复生物力学研究领域所存在的问题，如模型设计过于简化，多采用二维模型或旋转对称体模型，没有考虑到材料的物理性能与应力分布的关系等，以上颌中切牙烤瓷桩冠作为研究对象，采用三维有限元法对有桩与无桩，以及不同材料的桩对牙本质应力分布的影响问题进行了研究。

Focused on serveral shortcomings in the field of biomechanical research on tooth restoration with post, such as the too simplified modeling and not considering about influences on stress distribution in the dentin with different post materials etc., the three finite element analysis was made to discuss how the posts and posts materials influence the stress distribution in dentin
