Abstract
A dental color measurement tool disposed opposite an opening portion for capturing light from an artificial tooth to undergo color measurement with a color measurement device includes at least one pair of guide posts having an engaging portion corresponding to an engaging portion on the color measurement device side, and an abutment post disposed between the pair of guide posts and having a pointed convex shape to which the artificial tooth can be mounted. The abutment post has a color measurement reference surface in a color measurement light axis direction as the vicinity of a focus position of the color measurement device in a photographing state. When performing color measurement photographing, the artificial tooth is mounted to the abutment post to position the front thereof at the color measurement reference surface. Thus, the artificial tooth can be stably retained at a suitable position with respect to the color measurement device.
