A SYSTEM TO MONITOR MANDIBULAR MOVEMENTS IN REAL TIME

该项目的目标是开发一个高效和 用于监测人类运动的精确系统 在真实的时间里。 该系统将应用于几个 牙科实践领域。 它将被用来测量和显示 说话和咀嚼时的功能性运动， 存储这些运动的记录。 因为一个详细的 数学记录存储，系统将能够使用 为了确定牙齿修复后的功能变化， 治疗颞下颌关节功能障碍，正颌外科手术，或 正畸治疗 该系统包括一个基于个人计算机的控制单元， 非约束性口外安全带，其上附有一套 LED的，和两个探测器跟踪LED的空间。 的 在第一阶段开发的原型系统可以跟踪8个LED， 每秒32个周期。 数据按原样显示 收集并存储以供以后分析。 初始I期临床 调查表明，该系统是非约束性的， 操作简单，可采集并显示临床数据 兴趣 第二阶段的技术工作将集中于改进系统 精度，增加三维图形功能，以及 改进线束设计。 大型临床研究将 在一些牙科学科进行，以探索 系统的临床应用范围。

The objective of this project is to develop an efficient and accurate system for monitoring the movements of the human mandible in real time. The system will find application in several areas of dental practice. It will be used to measure and display the functional movements during speaking and chewing, and to store a record of those movements. Because a detailed mathematical record is stored, the system will be able to be used to determine functional change after dental restoration, treatment of TMJ dysfunction, orthognathic surgery, or orthodontic treatment. The system consists of a personal computer-based control unit, a non-restraining extra-oral harness to which is attached a set of LED's, and two detectors to track the LED's in space. The prototype system developed under Phase I can track 8 LED's at a rate of 32 cycles per second. Data are displayed as they are collected, and stored for later analysis. Initial Phase I clinical investigation has indicated that the system is non-constraining, simple to operate, and can collect and display data of clinical interest. Technical work in Phase II will concentrate on improving system accuracy, adding three dimensional graphics capabilities, and improving the harness design. Larger clinical investigations will be conducted in a number of dental disciplines in order to explore the range of clinical utility of the system.
