摘要/Abstract

摘要： 针对现有牙颌有限元建模方法存在低效和缺乏个性化的缺点,提出一种参数化的牙颌有限元自动建模方法。通过实体造型技术对牙颌初始三维几何模型进行处理,生成牙周膜、牙槽的三维几何模型;根据齿列的配置参数和单元参数对牙颌模型进行网格划分;基于Ansys的参数化程序设计语言,开发了面向牙颌的有限元自动建模系统,并在真实的牙颌数据集上进行了建模实验。实验结果表明该系统能自动高效地生成个性化牙颌系统的有限元模型。

关键词: 个性化牙颌系统, 牙颌实体造型, 自动有限元建模, 牙颌功能仿真

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
