我们在这里提出了一个基于解剖学的模型，提供了一个框架，用于模拟复杂的咀嚼过程的人类咀嚼系统。创建这个模型的最初动机是希望有一个人类颌骨的计算模型，可以用来模拟简单的咬合动作，并计算所涉及的牙齿上的应力和力。所创建的模型还提供了一个平台，可用于研究咀嚼系统的其他功能。为了构建这个全局模型，从通用数据集创建了头骨和颌骨的各个模型。咀嚼肌的几何模型也被创建并连接到适当的骨骼上。为了完成这个初始模型，创建了牙冠的表示，并包括颞下颌关节（TMJ）的基本模型。采用有限元方法求解了下颌骨咬合模拟过程中由加载条件产生的应力和应变。这里提出的模型也讨论了有关的整个肌肉骨骼系统的模型正在开发的生理项目的一部分。版权所有（C）2005 S.

We present here an anatomically based model of the human masticatory system that provides a framework for simulating the complex chewing process. The initial motivation for creating this model was the desire to have a computational model of the human jaw that can be used to simulate the action of simple bites, and to calculate the stresses and forces on the teeth that are involved. The model created also provides a platform that can be used to investigate other features of the masticatory system. To construct this global model, individual models of the bones of the skull and jaw were created from generic data sets. Geometric models of the muscles of mastication were also created and attached to the appropriate bones. To complete this initial model, representations of the-crowns of the teeth were created and a basic model of the temporomandibular joint (TMJ) was included. The finite element method was used to solve for the stresses and strains created by the loading conditions during a clenching simulation involving the mandible bone. The model presented here is also discussed in relation to a model of the entire musculo-skeletal system being developed as part of the Physiome Project. Copyright (C) 2005 S. Karger AG, Basel.
