1. A method for digitally detecting an intraoral structure by scanning the structure with an intraoral scanner, the scanned values of which contain location information data representing the spatial position of the scanning points and color information data representing color values of the scanning points,
wherein at least one color reference template having a reference color field corresponding to a reference color value of a reference color space is arranged in the scanning area of the structure, and
wherein the scanned color information data is corrected according to the distance between the reference color value and a scanned color value of the reference color field.
