摘要:
A dental tone match checking material is provided that makes possible the elaboration of better esthetics than in the prior art. The present invention is a dental tone match checking material and relates to a dental tone match checking material, wherein the difference (n1−n0) between the refractive index n1 of this material and the refractive index no of the cured product from the dental cement that is checked with the dental tone match checking material is in the range from −0.040 to +0.020.

There are provided an inorganic filler, multi-functional filler, an organic compound filler, a modified filler, and a dental coloring filler suitable in use as a filler in a dental composition, compositions having a resin matrix of an organic polymer material, as well as a process for producing the same. Disclosed are an inorganic filler which comprises an inorganic fine particle, wherein the surface of the inorganic fine particle is covered with polysiloxane. Also disclosed is a multi-functional filler which comprises an inorganic fine particle containing an acid reactive element, wherein a cement reactive phase is formed on the surface of the inorganic fine particle, and the cement reactive phase is further covered with polysiloxane. Also disclosed is an organic compound filler which comprises an organic-inorganic polymer particle or an organic polymer particle, wherein the surface of the organic-inorganic polymer particle or an organic polymer particle is covered with an inorganic film. Also, disclosed is a modified filler which comprises an inorganic fine particle, wherein the surface of the inorganic fine particle is covered with polyorganosiloxane. Also disclosed is a dental col ring filler, which comprises an inorganic particle and a coloring particle, wherein the inorganic particle and the coloring particle are unifoy mixed and dispersed, the surfaces of these particles are covered with poly(organo)siloxane. Further disclosed are dental compositions containing above fillers, and processes for producing above fillers.

An artificial teeth packaging container 1 includes an artificial teeth accommodating portion 7 for fixing a plurality of continuously arranged artificial teeth 2 detachably, and holding an arrangement position relation with an adjacent artificial teeth and an arrangement position relation with an upper or lower artificial molar teeth, in which the artificial teeth accommodating portion 7 covers the plurality of artificial teeth 2 from an occlusal plane in a state exposed around a cervical portion.
摘要:
Artificial teeth of upper and lower jaws, allowing easy operation by clarifying the three-dimensional positional relation of cusp tips and pits to contact with each other in occlusion. Each pair of artificial teeth may include cusp tips and pits, and the positional relation of the cusp tips and pits are set appropriately.
摘要:
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°.
摘要:
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. Using this shade guide enables precisely and easily discriminating the color of an evaluation target tooth.
