摘要
本研究以上颌中切牙天然牙为解剖学基础建立了三维有限元模型。分别以生理载荷、垂直载荷、４５°载荷及水平载荷作用于牙体，通过计算得到了不同载荷作用下牙本质的应力分布并进行了比较。
A three-dimensional finite element model was built by using central maxillary incisor as its anatomical basis.The physiological load,vertical load,45° load,and horizontal load are added on the tooth respectivel.Stress distribution in the dentine was computed and a comparison under adove different loads was made.
