PROBLEM TO BE SOLVED: To shorten the time and process for manufacturing an artificial tooth prosthesis, which is useful for manufacturing an artificial tooth prosthesis similar to a natural tooth, and to increase the force by tilting the mechanical properties. To provide a dental bulk block for cutting, which can bring about an effect of increased structural stability on the dispersion side of. SOLUTION: This is a glass ceramic block containing a crystal phase in an amorphous glass matrix, in which the main crystal phase is composed of lithium disilicate, and the additional crystal phase is lysia bright stone (Spodumene) and bargelite. It consists of at least one selected from (Virgilite) and lithium phosphate, has an inclination of the main crystal phase size with respect to the depth, and has no interface at the change point of the inclination value of the main crystal phase size. Provided is a dental bulk block for cutting, which is a tilting functional material. [Selection diagram] Fig. 1 |
