| Research Abstract |
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.
