【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。
[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.
