Abstract
An artificial tooth includes a prosthesis and an abutment including an insertion part inserted into the prosthesis in one direction and a protruding part protruding from the prosthesis, wherein the insertion part is slantingly formed so that the diameter of the outer peripheral surface of the insertion part increases in the one direction, and the protruding part is slantingly formed so that the diameter of the outer peripheral surface of the protruding part decreases in the one direction, and when the prosthesis is a workpiece structure, one end portion of the protruding part is coupled to an artificial tooth processing device.
Claims6
An artificial tooth comprising:
- a prosthesis;
- an abutment comprising an insertion part inserted into the prosthesis in one direction and a protruding part protruding from the prosthesis;
- and
- a buffer part which is located to cover an outer peripheral surface of the insertion part and comprises zirconia, the buffer part being entirely embedded within the prosthesis and positioned at an interface between the insertion part and the prosthesis,
- wherein the insertion part is slantingly formed so that a diameter of the outer peripheral surface of the insertion part increases in the one direction, and the protruding part is slantingly formed so that a diameter of an outer peripheral surface of the protruding part decreases in the one direction, and when the prosthesis is a workpiece structure, one end portion of the protruding part is coupled to an artificial tooth processing device, and
- wherein the prosthesis comprises at least one of crystallized glass, polymers, or ceramics, and the abutment comprises at least one of a titanium material, a chrome material, a cobalt material, platinum, gold, or an alloy thereof.
