Abstract
PURPOSE:To prepare an artificial tooth reduced in a feeling of physical disorder even under any illumination condition, by taking the photograph of a tooth while making the illumination condition to the adjacent tooth variable to display the same as a color image and judging the tooth color of the adjacent tooth on reference to the color sample data of the teeth. CONSTITUTION:The adjacent tooth of a tooth to be treated is photographed by a color camera 11 while illuminated under a definite illumination condition to be displayed on the picture of a color CRT 12 through a controller 14. Next, the adjacent tooth 17 to the tooth to be treated is displayed on the color CRT 12 in a magnified state and divided into regions as shown by broken lines. Each region of an artificial tooth is visually replaced with a shade guide while the color distribution of the adjacent tooth 17 displayed on the picture of the color CRT 2 is referred to. By this method, the color data of the adjacent tooth 17 and a floppy disk 13 having the number selection data of the shade guide stored therein are regenerated on the picture of the color CRT 12 and the artificial tooth is prepared on the reference to the regenerated display image.
