Abstract: Disclosed is a bulk block for manufacturing a prosthesis having high aesthetics and processability required for one-day dental prosthetic materials, which is a dental composite bulk block comprising a glass ceramic matrix and a polymer, wherein the glass ceramic matrix consists of an amorphous glass matrix and a crystalline phase dispersed in the glass matrix, the crystalline phase comprises as a main crystalline phase at least one selected from a leucite crystalline phase and a lithium disilicate crystalline phase, and has an average particle diameter of 0.01-1.0 ?m, and the polymer is included in an amount of 20-40 wt % with respect to the weight of the total bulk block. The bulk block has the advantages of improved mechanical properties, being capable of preventing microleakage, exhibiting excellent aesthetics, and enabling machining.

Abstract: Provided is a dental blank. The dental blank includes: a seating portion provided in an artificial tooth processing apparatus; and a material portion configured to be inserted into the seating portion, wherein the material portion includes a plurality of outer contacting portions in contact with an inner side of the seating portion, and may have a polygonal shape in a cross-section.

Abstract: A dental implant, and a manufacturing method for the same. The dental implant includes a form in which, in order to increase the strength of the connection between a metallic abutment and a dental prosthesis, the abutment and the prosthesis are integrally connected, wherein the prosthesis and the abutment are integrally connected to each other by means of a forming method.

Abstract: Proposed is a hybrid ceramic prosthesis. Since the prosthesis is made of a novel hybrid ceramic material, the prothesis has a similar color and transmittance to natural teeth, minimizes tooth removal during preparation for placement of the prothesis, is securely attached to the target tooth by snap-fit fastening to prevent detachment of the prothesis and re-treatment caused by the prothesis detachment, and can be more conveniently applied to the patient than conventional prostheses, enabling an one-day-one-stop dental procedure, thereby reducing burden to patients. The prothesis is useful as a primary crown.

Abstract: The present invention relates to a method for manufacturing a prefabricated crown by processing and tabulating the type, size, material and color of prefabricated crowns for sub-gingival and supra-gingival, and actual and try-in crowns by a table system (1), and a prefabricated crown manufactured therefrom, and the method includes a first step (S100) of classifying a plurality of prefabricated crowns by type and size by a first module (5) of the table system (1); a second step (S110) of classifying the plurality of prefabricated crowns by color and material by a second module (7) of the table system (1); a third step (S120) of tabulating the type, size, color and material data of the prefabricated crowns classified in the first and second steps (S100, S110) by a third module (9) of the table system (1), and assigning an identification code to each data; a fourth step (S130) of manufacturing the tabulated plurality of prefabricated crowns; and a fifth step (S140) of inputting the measured type, size, color and
