    摘要: Disclosed 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 according to which the crystalline size continuously increases from a lower end to an upper end of the block. The upper end of the block is configured to form the gingival side of an artificial tooth restoration material and the lower end of the block is configured to form the incisal side of the artificial tooth restoration material. The functionally gradient material has an average particle diameter within a range of 5 nm to 5.5 µm. The dental bulk block is manufactured using a same glass composition, wherein the same glass composition includes 60 to 83 wt% of SiO 2 , 10 to 15 wt% of Li 2 O, 2 to 6 wt% of P 2 O 5 , 1 to 5 wt% of Al 2 O 3 , 0.1 to 3 wt% of SrO, 0.1 to 2 wt% of ZnO, 1 to 5 wt% of a colorant, and 2.5 to 6 wt% of a mixture of Na 2 O and K 2 O.
