| Abstract | 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 SiO 2, no less than 10.0 mass% and no more than 20.0 mass% of Li 2O, and no less than 5.1 mass% and no more than 10.0 mass% of Al 2 O3; 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.
La présente invention vise à fournir un procédé de production rapide d'une prothèse dentaire précise (10). Ce procédé comprend : une étape de fusion, pour faire fondre un matériau qui contient de 60,0 % en masse à 80,0 % en masse (limites comprises) de SiO2, de 10,0 % en masse à 20,0 % en masse (limites comprises) de Li2O et de 5,1 % en masse à 10,0 % en masse (limites comprises) d'Al2O3; une étape de formation d'une ébauche en verre, pour obtenir une ébauche en verre par refroidissement et solidification du matériau fondu; une étape de formation d'une ébauche en disilicate de lithium pour obtenir une ébauche en disilicate de lithium, la phase cristalline principale étant constituée de disilicate de lithium, par chauffage de l'ébauche en verre; et une étape de traitement, pour soumettre l'ébauche en disilicate de lithium à un traitement par usinage. |
