Abstract: Provided is a dental bulk block made from a glass-ceramic material having a crystalline phase embedded in an amorphous glass matrix. The crystalline phase includes eucryptite and at least one lithium silicate-based crystalline phase selected from the group consisting of lithium metasilicate and lithium disilicate. The dental bulk block is a functionally graded material having a crystalline size gradient with respect to a depth thereof and having no interface at a point of change in main crystalline size gradient value. The bulk block that is heat-treated at 820° C. for 40 minutes exhibits a characteristic peak of a spodumene crystalline phase in an X-ray diffraction analysis result graph unlike the bulk block that is heat-treated at 820° C. for 2 minutes.

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.

Abstract: Provided is a dental bulk block for grinding processing. The dental bulk block includes a crystalloid, which includes lithium disilicate as a main crystal phase and silicate as a sub-crystal phase, and hyaline as a remainder. The dental bulk block is a functionally gradient material having a crystalline size gradient with respect to a depth thereof and having no interface at a change point of a crystalline size gradient value. The dental bulk block is useful for manufacturing an artificial dental prosthesis that is similar to natural teeth. Accordingly, the time and process for manufacturing the artificial dental prosthesis are shortened, and structural stability is increased in terms of dispersion of force due to gradient functionalization of mechanical properties.

Abstract: Disclosed is a machinable dental bulk block that is a glass ceramic block including an amorphous glass matrix and crystalline phases introduced into the matrix. A major crystalline phase is lithium disilicate and minor crystalline phases are lithium phosphate and at least one of spodumene and virgilite. The dental block is made of a functionally gradient material in which the major crystalline phase exhibits a gradient of particle sizes in a depth direction of the dental block and which has no interface at a point where the gradient of particle sizes of the major crystalline phase changes. The dental bulk block is useful for production of a dental prosthesis (artificial tooth) similar to a natural tooth. The dental bulk block can reduce time and the number of processing steps to manufacture a dental prosthesis and provides improved structural stability through good force distribution obtained by functionally graded mechanical properties.
