The present invention is a dental cut processing resin-based block that contains a resin matrix (A) and a spherical filler (B) having an average particle size in the range of 230-1000 nm. The dental cut processing resin-based block is characterized in that: at a thickness of 10 mm, the brightness (V) of a measurement color value, which is measured by using a color difference meter and which is of colored light according to the Munsell color system under a black background and under a white background, is less than 5.0 and a chroma (C) of the measurement color value is less than 2.0; and, at a thickness of 1 mm, the brightness (V) of a measurement color value, which is measured by using a color difference meter and which is of colored light according to the Munsell color system under a black background, is less than 5.0 and a chroma (C) of the measurement color value is at least 0.05, and the brightness (V) of a measurement color value, which is measured by using a color difference meter and which is of colored light according to the Munsell color system under a white background, is at least 6.0 and a chroma (C) of the measurement color value is less than 2.0. The present invention allows repair of a dental prosthesis produced from a block without using a pigment or a dye such that the external appearance thereof matches with the color tone of natural teeth, and makes it possible to provide a dental cut processing resin-based block that realizes continued harmony of the dental prosthesis produced from a block with the color tone of natural teeth.La présente invention concerne un bloc à base de résine de traitement de coupe dentaire qui contient une matrice de résine (A) et une charge sphérique (B) ayant une taille de particule moyenne dans la plage de 230 à 1000 nm. Le bloc à base de résine de traitement de coupe dentaire est caractérisé en ce que : à une épaisseur de 10 mm, la luminosité (V) d'une valeur de couleur de mesure, qui est mesurée au moyen d'un dispositif
