[Abstract]:In view of the shortcomings of the existing finite element modeling methods for dentistry and jaw, a parameterized finite element modeling method for dentistry and jaw is presented in this paper. The 3D geometric model of periodontal membrane and alveolar is generated by processing the initial 3D geometric model of the tooth by solid modeling technology, and the mesh of the model is divided according to the configuration parameters and unit parameters of the tooth column. Based on the parameterized programming language of Ansys, an automatic finite element modeling system for dental jaw was developed, and the modeling experiment was carried out on the real dental data set. The experimental results show that the system can automatically and efficiently generate the finite element model of the personalized dental and maxillary system.
