Abstract: The present invention relates to a method for preparing a lithium disilicate glass-ceramics containing silicate as a main component, and more particularly, to a method for preparing a glass-ceramics, which is capable of adjusting machinability or translucency according to a crystalline size by using a first heat treatment or a second heat treatment. To this end, a method for preparing a glass-ceramics containing a silica crystalline phase includes: performing a first heat treatment on a glass composition at a temperature of 400 to 850° C., so that a lithium disilicate crystalline phase and a silica crystalline phase each having a size of 5 to 2,000 nm are formed through the first heat treatment. After the first heat treatment, the method further includes performing a second heat treatment at a temperature of 780 to 880° C., so that translucency is adjusted by a temperature of the second heat treatment.

Abstract: Provided is a machinable abutment-integrated prosthetic block. The machinable abutment-integrated prosthetic block is structured such that an abutment is integrated with a crown block made of a material requiring no heat treatment after undergoing machining processing. The abutment and the crown block are integrated by an adhesive layer containing a cured product of a polymerizable organic compound. Therefore, the prosthetic block which is an integrated form of the abutment and the crown block can be processed by machining processing such as CAD/CAM processing. Therefore, the prosthetic block can be processed, by machining processing, into artificial teeth to be used as temporary teeth or permanent teeth and does not require no additional heat treatment after undergoing the machining processing, thereby shortening a treatment time for implant restoration, resulting in a one-day prosthesis procedure.
