摘　　要：目的研究在计算机上建立上颌中切牙的三维有限元数学模型。方法利用牙齿的系列薄层CT截面影像、图像处理软件、计算机辅助设计软件、结合Ansys三维有限元专用软件程序,建立三维有限元模型。结果建立了上颌中切牙的三维有限元模型。结论探索了一种新的牙齿三维有限元模型建立的方法;建立的牙齿三维有限元模型具有高度的相似性。Objective To discuss Construction of the three-dimensional finite element model of maxillary central incisor by using CT scanning technique. Methods In this experiment, three-dimensional finite element models were established with CT-scanning technique and image process software. Auto-CAD and Ansys softwares were used to analyse the model. Results By using the accurate results of the CT scanning technique, we could accurately copy the two-dimensional image of the model and imitate the real condition of maxillary central incisor. Conclusion Construction of the three-dimensional finite element model by using CT scanning technique is simpler, more efficient and more accurate than other methods.
