| Research Abstract |
Recently, dental students have a great difficulty to acquire the cutting high-technique for a short time, as air-turbine handpieces are further improved. Therefore, for elevating the education effect, we initiated the development of the dental patient robot for training the cutting techniques. Primarily, the methods for measuring the cutting forces and the rotational speed of air-turbine 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 was used one applied the eddy current. This load sensor is fixed under the cutting denture model. This patient robot has the mouth which was similar to one of the living body, and can show three waveforms of the normal force and the tilt-moment to toothaxis and the speed at real time in display of personal computer. And, this robot analyzes the cutting technique on the basis of these waveforms of cutting, and gives some comments to dental student. Further, we have developed an inclination angle measuring device using magnetism for especially training the preparation of crown to be the most important and difficult cutting technique. This device can be measured the inclination angle of handpiece in non-contacting and quantitative way while dental student does the preparation of crown, having enough accuracy in <plus-minus>10ﾟ range. Therefore, dental student can concretely do the cutting training to be controlled by comments'from ihis robot, concequently will be able to acquire the cutting techniques in shorter tim
