METHOD FOR PRODUCING DENTAL PROSTHESIS, METHOD FOR PRODUCING LITHIUM DISILICATE BLANK FOR DENTAL PROSTHESIS AND LITHIUM DISILICATE BLANK FOR DENTAL PROSTHESIS |
摘要 |
Provided is a method for quickly producing a dental prosthesis with a good accuracy.;The method for producing a dental prosthesis including: a melting step of melting a material including no less than 60.0 mass % and no more than 80.0 mass % of SiO2, no less than 10.0 mass % and no more than 20.0 mass % of Li2O, and no less than 5.1 mass % and no more than 10.0 mass % of Al2O3; a glass blank production step of cooling to solidify the molten material to obtain a glass blank; a lithium disilicate blank production step of heating the glass blank to obtain a lithium disilicate blank whose main crystalline phase is lithium disilicate; and a processing step of processing the lithium disilicate by machining. |
