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.
