Abstract

The tooth consists of enamel, dentin, and pulp. The outer surface of the enamel, the interface between dentin and pulp, as well as the interface between enamel and dentin is complicated. To better capture the details of the tooth, Nano Computed Tomography (CT) is used to obtain the detailed images of the tooth, and the CT images are further imported to construct the 3D structure of the tooth. This 3D model provides a precise representation of the tooth's geometry and material properties, and a numerical model is proposed based on the local radial basis function collocation method (LRBFCM), which is suitable for analyzing the complex geometry. The combination of Nano-CT and the LRBFCM offers a powerful tool for analyzing the mechanical behavior of the tooth. The stress distribution and defects of the tooth are fully studied based on the proposed numerical model.

基于局部RBF配点法的三维层状复合材料结构弹性牙体分析

牙齿由牙釉质、牙本质和牙髓组成。牙釉质的外表面、牙本质与牙髓之间的界面以及牙釉质与牙本质之间的界面是复杂的。为了更好地捕捉牙齿的细节，采用纳米计算机断层扫描（CT）获得牙齿的细节图像，并进一步导入CT图像构建牙齿的三维结构。基于局部径向基函数配置法（LRBFCM）建立了适合于复杂几何结构分析的数值模型。纳米ct和LRBFCM的结合为分析牙齿的力学行为提供了强有力的工具。基于所提出的数值模型，对齿的应力分布和缺陷进行了全面的研究。
