对人体咀嚼系统中动态事件的生物工程模拟相对较新。一个主要的优势是它们能够在因果情景中整合结构和功能。通过允许对这些相互作用进行详细分析，以及假体添加的原型，这些模型产生了工作假说。它们使用中的重要问题包括结构几何的输入和测量、影响动力学的参数的选择(例如惯性特性和粘弹性)以及建模过程的性质(例如模型是由肌肉收缩的运动学驱动的，还是由运动通道的运动学定义的)。目前，几乎没有公认的标准或约定来管理人类颌骨中的这些计算数据，并且所使用的数据通常来自多个不同的来源。本文综述了动力学建模在人体咀嚼系统中的方法、假设和关键应用。它考虑了成像的作用，未知或不可验证数据的假设施加的限制，以及尽管存在这些障碍，建模如何成为一种有用的研究技术。这篇评论最后对为教育目的创建虚拟模型发表了评论。
Bioengineered simulations of dynamic events in the human masticatory system are relatively new. A primary advantage is their ability to integrate structure and function in cause-and-effect scenarios. By permitting detailed analyses of these interactions, and the prototyping of prosthetic additions, the models generate working hypotheses. Significant issues in their use include the importation and measurement of structural geometry, the choice of parameters affecting dynamics (e.g. inertial properties and viscoelasticities) and the nature of the modeling process (e.g. whether models are kinetically driven by muscle contraction, or kinematically defined by movement channels). Presently, there are few accepted standards or conventions for managing these computational data in the human jaws, and the data used are often derived from multiple and disparate sources. This review focuses on the approaches, assumptions, and key applications of dynamic modeling in the human masticatory system. It considers the role of imaging, the restrictions imposed by assumptions of unknown or unverifiable data, and how modeling can be a useful research technique despite these hurdles. The review concludes with a comment on creating virtual models for educational purposes.
