Abstract

Abstract: Aiming at overcoming the disadvantages of currentmodeling methods for dental system, such as poor efficiency and lack of personality, a method for automatic generation of finite element model for personalized dental systemis proposed. On the basis ofthe original 3Ddental model, a3Dmodel of pericementum and phatnomaiscreatedby technology of solid modeling.According tothe configuration parameters of dentition and finite elements, a finite element model of the personalized dental system is generated. Based on Ansys parametric design language, anautomatic finite element modeling system of dental system is implemented. By this modeling system, experiments are performed based on the real data of dental system and the results show that this proposed method can automatically generate the finite element model for the personalized dental systemefficiently.

Key words: personalized dental model, solid modeling for dental system, automatic finite element modeling, simulation of dental function
