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

研制了一种新型的计算机显示咬合牙列压力分布的装置。该装置使牙科医生能够从形态和功能的角度对咬合进行“定量评估”。该传感器，即咬合板，由夹在两个印有导电条的基板之间的导压橡胶(PCR)组成。这些条纹形成了最大4096个感应点的X-Y栅格作为电极。在咬合力增加的点上的每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/或将数据保存在磁盘中，作为一种功能检查方法，测量误差在允许的范围内，我们认为这将是诊断、治疗和分析咬合的有效方法。

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.
