Provided is a mill blank for dentures that makes it possible to simply and efficiently produce highly aesthetic dentures without sacrificing congruence using a CAD/CAM system to replicate "highly congruent dentures that have a repair mark" that are obtained by making adjustments to dentures produced using standard dentures. According to the present invention, a mill blank for dentures is produced by fixing artificial tooth parts that comprise an artificial tooth material and fixing parts of the artificial tooth parts to a denture plate cutting part that comprises a denture plate material. The artificial tooth parts for molars have standard molar shapes and do not require cutting. The artificial tooth parts for front teeth are thicker than standard front teeth but substantially the same width as standard front teeth. The artificial tooth parts for the molars and the artificial tooth parts for the front teeth are arranged in a standard pattern for the corresponding teeth such that the fixing parts are not exposed at the surface during cutting.
