摘要：
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 µm, 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.
