When we accomplished this study, in 2003, we measured the characteristics of various food which varied during mastication, and determined as material data. In addition, we measured the masticatry jaw movement. As a result of these, it is suggested that the masticatory jaw movement that it was influenced from mechanical stimulation to a periodontal mechanoreceptor and a muscle spindle in order to be controlled to destroy bolus efficiently.Furthermore, we established a method to simulate by the three dimensions limited element analysis that was a kind of calculation dynamics technique with a computer to develop it as bionics. Surface morphology and positional relationship of upper a d lower teeth were measured by using a non-contact-type surface morphology measurement system and made the three dimensions limited element model on the basis of the data from the morphology measurement, characteristics of the bolus, jaw movement. By this, it was able to reveal the relationship between the behavior of bolus in mouth and the stress to teeth and periodontal ligament and mandible.In 2004, this method applied to normal occlusion and malocclusion and examined the relationship between characteristics of bolus and the masticatry jaw movement. By this, it was able to reveal the chewing functional disorder by malocclusion.

当我们在2003年完成这项研究时，我们测量了各种食物在咀嚼过程中的变化特征，并确定为材料数据。此外，我们还测量了咀嚼下颌的运动。在此基础上，提出了通过机械刺激对牙周力感受器和肌梭的影响来控制咀嚼运动，从而有效地破坏牙周力感受器和肌梭，进而建立了三维有限元模拟的方法，这是一种利用计算机进行仿生发展的计算动力学技术。采用非接触式表面形态测量系统测量上、下牙的表面形态和位置关系，并根据测量的形态、团块特征、颌骨运动等数据建立三维有限元模型。2004年，将该方法应用于正常牙合和错(牙合)畸形患者，研究了牙丸特性与咀嚼下颌运动的关系。由此可以揭示错(牙合)所致的咀嚼功能障碍。
