  • Patent number: 9173727
    Abstract: In a shade guide, a plurality of shade tabs whose colors are mutually different are arranged regularly based on the colors. The arrangement of the plurality of shade tabs is an arrangement determined based on: S values and V values that are determined according to to which areas, from among areas partitioned by a plurality of straight lines in an L*-C* plane, the coordinates of the colors of the shade tabs belong, and H values that are determined according to to which areas, from among areas partitioned by a plurality of straight lines in an a*-b* plane, the coordinates belong. S groups, each of which is a shade tab group having a common S value, are arranged in the shade guide. V rows, each of which is a shade tab group having a common V value, are arranged in each S group. In each V row, the plurality of shade tabs have mutually different H values and are aligned in an order that is in accordance with the H values.

  • Patent number: 8128404
    Abstract: It is intended to provide artificial teeth designed to easily enable bilateral balanced occlusion with less grinding adjustment. According to the present invention, angles formed by occlusal facets of the artificial teeth with an occlusal plane are suitably set. An artificial tooth for maxillary central incisor, for example, has a protrusive facet and a retrusive facet on an incisal edge thereof. Of angles formed by the protrusive facet with the occlusal plane, the angle in cross section along a sagittal plane is 22.0° to 25.5°, and the angle in cross section along a coronal plane is 1.5° to 6.5°. Of angles formed by the retrusive facet with the occlusal plane, the angle in cross section along the sagittal plane is 20.5° to 23.0°, and the angle in cross section along the coronal plane is 1.5° to 6.5°.
