Elastic dental analysis of 3D layered composite structures based on the local RBF collocation method

Year: 2025

Type: article

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.
