【Task】 In the conventional technology, the color tone of natural teeth cannot be reproduced properly due to insufficient color tone design technology, and in order to reproduce the color tone, a complicated layer structure, a layer structure exceeding 6 layers, or a continuous layer structure is required. Since it is necessary to manufacture a block having a layer structure, there is a problem that the manufacture of the block is technically complicated and difficult. [Solution] The resin block for dental cutting excellent in aesthetics can be obtained by maintaining the relationship between the specific contrast and the color tone of each layer constituting the resin material for dental cutting.
