PROBLEM TO BE SOLVED: To provide a novel prosthetic appliance machining method and machining device effectively using a dental model prepared mainly for checking and verifying a fixing state of the prosthetic appliance, as holding means when three-dimensionally machining a prosthetic appliance material block.SOLUTION: The prosthetic appliance machining method according to the present invention comprises: creating a pseudo tooth base 10 representing a crown shape of an abutment tooth T on the basis of denture mold data of a patient P, and forming, on the pseudo tooth base 10, a suction hole 13 communicating from the crown to another external surface; reversing concave-convex relationship of three-dimensional data of the crown in the pseudo tooth base 10 to cut a joining part W2 in a prosthetic appliance material block WB; and then installing the prosthetic appliance material block WB on the crown of the pseudo tooth base 10, with it brought into close contact with the crown, applying vacuum air to the suction hole 13 of the pseudo base 10, and three-dimensionally cutting a body surface W3 of the prosthetic appliance material block WB, with the prosthetic appliance material block WB held by the pseudo tooth base 10.SELECTED DRAWING: Figure 2 |
