项目摘要

Recently, as air-turbine handpieces are improved, the dental students have a great difficulty to acquire the cutting high-technique for a short time. Therefor, for elevating the effect of its education, we initiated the development of the dental patient robot for traninng the cutting techniques. Primarily, tye metods for measuring the cutting forces and the rotatinal speed of air-tubine under cavity preparation were investigated, consequently, the touch sensor used for the engineering robot was applied as load sensor for measuring the cutting forces, and the rotational speed sensor was used one applied the eddy current. This load sensor can continuously measur the normal force and the tilt-moment, and is fixed under the cutting deture model. Incidentally, the dental manequins in general uses have not a tongue in its mouth, and the space of its inner structure is wide. So, we deveroped new patient robot of which the mouth was similar to one of the living body. This dental patient robot can show the cutting forces under cavity preparation at real time in display of parsonal computer. And the dental patient robot does the analysis of the waves of cutting forces according to the standard waves of cutting forces for estimating the cutting techniques of dental student, after the cavity preparation, gives some comments on cutting techniques to dental student. Next, the dental student can concretely do the traning of cutting to be controlled by these comment, consequently can acquire the cutting techniques in shorter time.

近年来，随着空气涡轮机手机的改进，牙科学生在短时间内掌握切割高新技术存在很大困难。因此，为了提高其教育效果，我们启动了牙科患者机器人的开发，用于训练切割技术。首先研究了型腔制备过程中切削力和空气管转速的测量方法，并采用工程机器人用触摸传感器作为切削力测量的载荷传感器，转速传感器采用涡流式测量。该载荷传感器可以连续测量法向力和倾斜力矩，并固定在切割缝合模型下方。顺便提及，一般使用的牙科人体模型的嘴里没有舌头，并且其内部结构的空间很宽。因此，我们开发了一种新型病人机器人，其嘴巴类似于活体。该牙科患者机器人可以在帕尔森计算机的显示屏上实时显示腔体制备过程中的切削力。牙科患者机器人根据标准切削力波对切削力波进行分析，以评估牙科学生的切削技术，在腔体准备后，对牙科学生的切削技术进行一些评论。接下来，牙科学生可以通过这些注释来具体进行切割训练，从而可以在更短的时间内掌握切割技术。
