Development of a Six-Degree-of-Freedom Jaw Movement Analyzer for Masticatory Movement

咀嚼运动被认为是一种功能性的、生理性的运动，但同时也是一种后天的、无意识的、习惯性的运动。为了研究咀嚼运动的功能和生理运动特征，因此，需要一种高性能的测量装置，以充分考虑测量装置对人体的生理影响，本研究设计了一种能够测量6度角的下颌运动分析仪，研制了一种对人体生理影响最小的100 μ m以下的六自由度下颌运动分析仪，并研制了一种能够检测咀嚼运动功能和生理运动特性的测量系统。数据处理部分和笔记本电脑。在开发过程中收集了设计所需的材料。根据这些材料， ...更多信息 建立了基本设计。之后，在实验模型上对问题进行了评估，并构建了原型装置，重点是使用附着在上下颌牙弓之间的机械结构的检测结构，以研究运动的轻盈性和平滑性。此外，还通过儿童受试者测量下颌运动对牙龈咀嚼的影响，对充分考虑生理影响的附着方法进行了研究。本研究的目的已基本实现，并在日本口腔功能学会上发表了结果。今后的研究将致力于开发一种系统，提供牙科医生想要知道的下颌功能诊断信息通过将检测结构放置在人体上，并在餐桌上测量下颌运动，在监视器上进行真实的实时的测量，还有几个基本问题需要解决，因此本研究将继续进行。少

Masticatory movement has been considered as functional and physiological and yet acquired, unconscious and habitual. It was difficult to fulfill the measuring requirements with conventional devices.To investigate the functional and physiological movement characteristics of the masticatory movement, it was necessary a high performance measuring device that consider the physiological influence sufficiently to human by the measuring device.In this study a jaw movement analyzer with a capability of measuring the 6-degree-of-freedom below 100 microns with minimum physiological influence to human, as well as a measuring system that is able to detect the functional and physiological movement characteristics of masticatory movements, were developed.The developed 6-degree-of-freedom jaw movement analyzer is composed of jaw movement detecting structure, data processing part and notebook computer.In the development the materials necessary for designing were gathered. Based on these materials the … More basic design was established. Afterwards, the problems were evaluated on the experimental model and a prototype device was constructed, focusing on the detecting structure using a mechanical structure attached between the tooth arches of both maxillary and mandible to investigate the lightness and smoothness of the movement. Also an investigation on the attaching method giving a full consideration on the physiological influence was carried out using pediatric subject measuring a jaw movement on gum mastication.The aim of this study has almost accomplished and the results were presented at the Japanese Society for Stomatoghnatic Function.The future research will be on the development of a system that delivers the diagnostic information of jaw function that dentists want to know in real time on the monitor by placing the detecting structure on human and measure the jaw movement at the dining table.There are still several fundamental problems that must be solved so this research will continue.
