|1. (WO2018139105) CERAMIC BODY FOR DENTAL PROSTHESIS AND METHOD FOR PRODUCING SAID BODY|
|Applicants:||ADAMANT NAMIKI PRECISION JEWEL CO., LTD.
|Title:||CERAMIC BODY FOR DENTAL PROSTHESIS AND METHOD FOR PRODUCING SAID BODY|
Provided are: an easily producible ceramic body for a dental prosthesis capable of minimizing any irregularity in the quality of unitary ceramic bodies for dental prostheses associated with increases in diameter; and a method for producing said body. This ceramic body for a dental prosthesis comprises a ceramic material, has a diameter of 50 mm or more, and is molded into a circular planar shape and a disc-shaped external shape. In this method for producing a ceramic body for a dental prosthesis, a ceramic material is prepared, the ceramic material is molded by press molding or using a machine tool, the ceramic material is pre-sintered at a temperature that is 700 to 100°C below the sintering temperature at which the theoretical density is obtained, and a ceramic body for a dental prosthesis having a diameter of 50 mm or greater is prepared, said body being molded to have a circular planar shape and a disc-shaped external shape.
