<p>PROBLEM TO BE SOLVED: To set a reflecting light to sufficiently incident on a light receiving part of a laser sensor by uniformly containing pigment particles having a specific refraction index to a specific wavelength laser beam. SOLUTION: Titanium dioxide or pigment particles having a high refraction index, concretely, 2.0 or more to a laser beam not less than a wavelength 0.5μm and not more than 0.75μm, which is the wavelength range of the red laser beam, is uniformly contained in a base material of a dental prosthetic substance model 2. A laser sensor 13 for measuring the three-dimensional shape of the dental prosthetic appliance model 2 is arranged on a Z-axial table 23, the red laser beam 14 is projected on the dental prosthetic appliance model 2 mounted on a rotary table 24 in parallel to the Z axis, and the three-dimensional shape of the dental prosthetic substance model 2 is measured. A dental prosthetic substance as a completion is thus processed by a dental prosthetic substance manufacturing device based on the measurement data.</p> |
