Development of computerized measuring apparatus of occlusal area and pressure, Occlusal multi-scanner'.

开发了一种新的计算机设备，用于可视化牙列咬合上的压力分布。该设备使牙医能够从形态学和功能的角度定量地评估咬合。传感器，咬板，是由压力导电橡胶（PCR）夹在两个基材之间印刷薄导电条纹。这些条纹形成一个X-Y栅格，最多4096个传感点作为电极。在咬合力增加的点上的每一个阻力量都被转换成压力值，并由微型计算机存储。软件系统不仅可以在CRT屏幕上以散点图的形式显示四种不同颜色的压力水平，还可以将数据输出到打印机和/或保存在磁盘中。作为一种功能检测方法，测量误差在允许范围内。我们认为这将是诊断、治疗和分析闭塞的有效方法。

A new computerized device to visualize pressure distribution on the occluded dentition was developed. The device enables the dentist to evaluate occlusion" quantitatively from the morphological and functional standpoints. The sensor, bite plate, is consisted of a pressure conductive rubber (PCR) sandwiched in between two substrates printed with thin conductive stripes. These stripes forms a X-Y grid of maximum 4096 sensing points as electrodes. Each amount of resistance on the point where bite force is added is transformed into the value of pressure and memorized by a microcomputer. A software system can not only display the pressure level by four different colors on the CRT screen as a scattergram, but also output the data to the printer and/or save them in a disk.As a method of functional examination, the measurement errors fell in a permissible range.We thought it would be an effective way in diagnosing, treating, and analyzing the occlusion.
