Though the force required to crush food is varied with kind of foods, the discrimination of the mechanical property of food and a suitable exhibition of muscle force are important to smooth masticatory movement. Especially when the hard food is crushed, the sudden change of occlusal force and the sudden change of mandibular position occur. It is necessary to clarify the change of muscle activity during food crushing corresponding these sudden changes. For clarifying the masticatory system and establishing the rule of planning on the removable partial denture, it is necessary to grasp the influence of presso-receptive information of the periodontal tissues on the sudden change of interocclusal force. There are a few investigation on the silent period of myoelectric discharge of masticatory muscles during food crushing, though the activity of masticatory muscles changes corresponding the change of occlusal force and the change of mandibular position. On the other hand, in the cases of im … More plant they have not function of periodontal tissues, then for clarifying the influence of presso-receptive information of the periodontal tissues, it is very interest to investigate the change of activity in the masticatory muscles in the cases of implant corresponding change of occlusal force and mandibular position during food crushing. While the mastication is repeated smooth movement by the control system of mandibular movement, the mandibular position may adapt to given situation, when the incorrect mandibular position is given. Therefore the investigation of adaptation of mandibular masticatory movement to given laterally shifted intercuspal position in the denture wearer will be taking a rule of diagnosis on the incorrect mandibular position. In this study, four items of the investigation; hardness discrimination ability of food, presso-receptive sensation and hardness discrimination ability of food in the cases of implant denture, appearance of silent period during food crushing, and adaptation of mandibular masticatory movement to given laterally shifted intercuspal position were studied .

虽然咀嚼食物所需的力因食物种类而异，但对食物力学性质的辨别和肌肉力量的适当发挥对咀嚼运动的顺利进行是重要的。特别是当坚硬的食物被压碎时，咬合力会发生突变，下颌位置也会发生突变。有必要阐明与这些突然变化相对应的食物破碎过程中肌肉活动的变化。掌握牙周组织的压力感受信息对咬合力突变的影响，对于阐明咀嚼系统，建立可摘局部义齿的设计原则是十分必要的。虽然咀嚼肌的活动会随着咬合力的变化和下颌位置的变化而发生变化，但对咀嚼肌在咀嚼食物过程中肌电活动的静默期的研究却很少。另一方面，在IM的情况下， ...更多信息 由于种植体本身不具有牙周组织的功能，因此研究种植体在咀嚼食物过程中咀嚼肌活动的变化以及咬合力和下颌骨位置的变化对牙周组织压力感受信息的影响是非常有意义的。在下颌运动控制系统的控制下，咀嚼运动是一种重复的平滑运动，当下颌位置不正确时，下颌位置可以适应特定的情况。因此，研究牙尖交错位对下颌咀嚼运动的适应性，将为正确的下颌位置诊断提供依据。在这项研究中，四个项目的调查，食物的硬度辨别能力，压力感受和食物的硬度辨别能力的情况下，种植义齿，出现沉默期的食物粉碎，并适应下颌咀嚼运动的牙尖交错位置侧向移位进行了研究。少
