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

摘要

An object of the present invention is to provide a method for rapidly manufacturing the high-precision dental prosthesis 10, and contains SiO 2 of 60.0 mass% or more and 80.0 mass% or less, Li 2 O of 10.0 mass% or more and 20.0 mass% or less, and Al 2 O 3 A melting step of melting a material containing in an amount of 5.1% by mass to 10.0% by mass, a glass blank manufacturing step of cooling and solidifying the molten material to obtain a glass blank, and heating the glass blank so that the main crystalline phase is lithium disilicate It shall include the lithium disilicate blank manufacturing process of obtaining a lithium phosphorus disilicate blank, and the processing process of machining a lithium disilicate blank.
