    Abstract: In color reproduction for a dental restorative material, in order to achieve a color that closely matches the color of the natural tooth, one technique that is used is to form a mill blank by laminating layers of materials having different colors. However, misidentification of layers frequently occurs. The present invention is a dental mill blank having a plurality of layers and the dental mill blank has a visual identifying portion by which the plurality of layers are visually identifiable. The visual identifying portion may be provided by color or by structure. Providing the visual identifying portion by color refers to coloring the surface of a layer of the dental mill blank and providing the visual identifying portion by structure refers to forming microscopic or macroscopic irregularities in the entire periphery or part of a layer surface.

    Abstract translation: 在牙科修复材料的颜色再现中，为了获得与天然牙齿的颜色紧密匹配的颜色，所用的一种技术是通过层压具有不同颜色的材料层而形成研磨坯料。 然而，频繁发生层错误识别。 本发明是一种具有多个层的牙科磨机坯料，并且牙科磨机坯料具有目视识别部分，通过该视觉识别部分可以可视地识别多个层。 视觉识别部分可以通过颜色或结构来提供。 通过颜色提供视觉识别部分是指对牙科磨坊坯料的表面进行着色，并且通过结构提供视觉识别部分是指在整个表面或整个表面的一部分形成微观或宏观的凹凸。

    Abstract: A dental mill blank having a multi-layer structure has been required to improve the reproducibility of a color tone of the natural tooth in a dental crown restoration cut by CAD/CAM technique. Especially, a reproduction of the color tone of a cavity or a groove is required in a dental crown form of the molar tooth.The present disclosure provides a dental mill blank having three or more layers wherein a color of a 30% position layer which includes a 30% position which is a position spaced from a surface of the dental mill blank of a W layer-side by 30% satisfies a specified relational expression, and a contrast ratio of the 30% position layer is within a range of the contrast ratio of the D layer×(0.70 to 1.00).
