PROBLEM TO BE SOLVED: To provide a dentistry practical training evaluation apparatus and a dentistry practical training evaluation system capable of objectively and quantitatively evaluating the shape of cavity formation and a support base formation.;SOLUTION: The dentistry practical training evaluation apparatus employs a laser displacement gauge 1 using a point-laser for three dimensional measurement. In measurement of cavity formation, a rotary encoder 7 detects rotation angle while moving a laser displacement gauge in the x-axis direction and rotating an object to be measured 8 on the z-axis centered to thereby spirally acquire dot group data. In measurement of support base formation, the above control is made while rotating the laser radiation angle of the laser displacement gauge 1 by a certain angle (for example, 45°) on the y-axis centered, and calculates the values to acquire three-dimensional data. Quality of the configuration is evaluated based on a difference in volume between the configuration data of a model tooth and a configuration data of a tooth made by a trainee.;COPYRIGHT: (C)2014,JPO&INPIT
