The objective of this study was to create a three-dimensional mathematical model of a human masticatory system, including the mandible, the dentition and the temporomandibular joints. Object of research was one 20 year old dead man. The research was approved by Committee of bioethics (Kaunas University of Medicine). Required extent of computed tomography scanning and required high amount and high resolution of images increased X-ray radiation for the object and made this research impossible to perform on alive human. Spiral computed tomography scanning was performed to achieve two-dimensional images, necessary for creating three-dimensional model. The 3D modeling was done using the "Image pro plus" and "Imageware"software. A three-dimensional physiological (normal) model of a human masticatory system, simulating the mandible, the dentition and the temporomandibular joints was generated. This model system will be used subsequently in stress analysis comparison for the physiological and pathological systems after improvement of its physical properties. We suggest that computer simulation is a promising way to study musculoskeletal biomechanics of masticatory system.
本研究的目的是创建一个包括下颌骨、牙列和颞下颌关节的人类咀嚼系统的三维数学模型。研究对象是一名20岁的男性死者。该研究得到了生物伦理委员会（考纳斯医科大学）的批准。计算机断层扫描所需的范围以及所需的大量高分辨率图像增加了研究对象所接受的X射线辐射，使得该研究无法在活人身上进行。进行螺旋计算机断层扫描以获取创建三维模型所需的二维图像。使用“Image pro plus”和“Imageware”软件进行三维建模。生成了一个模拟下颌骨、牙列和颞下颌关节的人类咀嚼系统的三维生理（正常）模型。在改善其物理特性后，该模型系统随后将用于生理和病理系统的应力分析比较。我们认为计算机模拟是研究咀嚼系统肌肉骨骼生物力学的一种有前途的方法。
