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

研制了一种新的计算机化咬合牙列压力分布可视化装置。该设备使牙医能够从形态和功能的角度定量评估咬合。该传感器，咬板，是由一个压力传导橡胶（PCR）夹在两个基板印刷薄导电条纹。这些条纹形成最多4096个感测点作为电极的X-Y网格。咬合力施加点的每一个阻力值都被转换成压力值，并由微型计算机存储。软件系统不仅能在CRT屏幕上以四种不同颜色的散点图形式显示压力值，而且能将数据输出到打印机或存入磁盘，作为功能检查的方法，测量误差在允许范围内，为阻塞的诊断、治疗和分析提供了一种有效的方法。

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.
