METHOD FOR PRODUCING DENTAL PROSTHESIS, METHOD FOR PRODUCING LITHIUM DISILICATE BLANK FOR DENTAL PROSTHESIS AND LITHIUM DISILICATE BLANK FOR DENTAL PROSTHESIS

摘要

The purpose of the present invention is to provide a method for quickly producing an accurate dental prosthesis (10). This method comprises: a melting step for melting a material that contains from 60.0% by mass to 80.0% by mass (inclusive) of SiO2, from 10.0% by mass to 20.0% by mass (inclusive) of Li2O and from 5.1% by mass to 10.0% by mass (inclusive) of Al2O3; a glass blank forming step for obtaining a glass blank by cooling and solidifying the melted material; a lithium disilicate blank forming step for obtaining a lithium disilicate blank, wherein the main crystal phase is configured of lithium disilicate, by heating the glass blank; and a processing step for subjecting the lithium disilicate blank to machine processing.
