人工歯の研磨方法
Document Type and Number:
Japanese Patent JP6876297
Kind Code:
B2
Abstract:
An artificial tooth 30 to be polished is fixed at a tooth neck 32 side and rotated about a tooth axis 33. Abrasives, preferably elastic abrasives formed by kneading abrasive grains into or supporting abrasive grains on an elastic material, are ejected together with a compressed gas at an ejection pressure of from 0.1 MPa to 0.5 MPa onto an occlusal portion 31 side of the artificial tooth 30 while the artificial tooth 30 is being rotated. The abrasives are ejected at an inclination angle θ with respect to the tooth axis 33 of the artificial tooth 30 of from 0° to 90°, and preferably from 15° to 75°. Portions on the occlusal portion 31 and side surfaces 38 of the artificial tooth 30 are thereby polished at the same time by the abrasive sliding over these portions.
