| 20090035738 | Tooth for tooth model, comprising enamel portion impregnated with resin or low melting point glass, and method for producing the same - An object of the present invention is to provide a tooth model capable of exhibiting grinding feel similar to that of a natural tooth, with which students aspiring to become dentists experience intraoral work and perform training related to a treatment, and also experience formation of an abutment tooth, formation of cavity or the like. A difference in the grinding feel between tooth enamel and dentin, which constitute a natural tooth, is reproduced by impregnating a sintered body formed integrally of an inorganic powder such as alumina with a thermosetting resin or a low melting point glass to form an enamel portion. | 02-05-2009 |
| 20100151418 | SET OF ARTIFICIAL TEETH OF ANTERIOR TEETH LINEARLY CONTACTING WITH EACH OTHER - In a set of artificial teeth, at least one of mutually adjacent artificial anterior teeth includes abutting faces which contacts linearly with the other one so as to form abutting lines and capable of continuously moving the positions of the linear contact, the abutting faces being formed of any one of circular columnar surface, elliptical columnar surface, and conical surface. | 06-17-2010 |
| 20100151419 | ARTIFICIAL TEETH - The invention provides artificial teeth arranged in plates attached in an oral cavity as a dental prosthetic appliance, in which arrangement direction indication parts showing a directivity of arrangement in the plates extending in an apical-cervical direction or in a mesiodistal direction are provided at a vestibular side or an oral side. The arrangement direction indication parts extending in the apical-cervical direction are positioned linearly as seen from the vestibular side in a occluded state of mandibular teeth and maxillary teeth. The arrangement direction indication parts extending in the mesiodistal direction are positioned linearly as seen from the vestibular side in the state arranged in plates. The artificial teeth are arranged at an appropriate position according to an oral environment of each patient, without requiring advanced skills and experiences. | 06-17-2010 |
| 20100151422 | ARTIFICIAL ANTERIOR TOOTH HAVING FRICTIONAL SURFACE AT LINGUAL SIDE, AND A SET OF ARTIFICIAL TEETH, AND DENTURE - Provided is an artificial anterior tooth capable of grinding the food. The lingual side of an artificial anterior is provided with a protuberance for forming a frictional surface dented in an arch shape as seen from the mesiodistal direction, and the labial side of an opposite artificial lower tooth is provided with a protuberance for forming a sliding surface abutting on the frictional surface and sliding on the frictional surface by sliding motion of upper and lower jaws. | 06-17-2010 |
| 20100151424 | ARTIFICIAL MOLAR TEETH - The invention provides artificial teeth arranged in plates attached in an oral cavity as a dental prosthetic appliance, in which one or more linear arrangement direction indication parts showing the arrangement direction in the plates are provided on an occlusal plane of each of the molar teeth. At least one set of arrangement direction indication parts of the adjacent molar teeth is configured so as to extend generally in parallel direction. At least one set of arrangement direction indication parts of the antagonist upper molar teeth and lower molar teeth is configured so as to extend generally in parallel direction. The artificial molar teeth are arranged at an appropriate position according to the oral cavity environment of each patient, without requiring advanced skills and experiences, being applicable to various arrangement of artificial teeth. | 06-17-2010 |

| 20110039230 | SET OF ARTIFICIAL TEETH WITH NO ABUTMENT AT HIGHEST CONTOURS - The present invention is to provide a set of easily arranged artificial teeth in which shapes of abutment surfaces of adjacent artificial teeth are not varied. In the set of artificial teeth, at least two artificial teeth adjacent to each other in a mesial-distal direction respectively have highest contours, one of the highest contours on the adjacent sides is positioned on an occlusal surface side and a buccal surface side relative to the other, and the artificial teeth are abutted with each other at abutment positions between the highest contours of both the artificial teeth in the occlusal direction and the buccolingual direction. Parting lines of molds for forming the artificial teeth respectively pass through the highest contours. | 02-17-2011 |
| 20110039231 | SET OF ARTIFICIAL TEETH HAVING CONVEX ADJUSTMENT SURFACE - A set of artificial teeth allows for easy occlusion adjustment without high precision in arrangement. One of a pair of occluding upper and lower artificial molar teeth has convex adjustment surfaces which are formed of a spherical surface, a cylindrical surface or a conical surface on an occlusal surface thereof, and the other of the pair of artificial molar teeth has opposing surfaces which are formed of a flat surface, a spherical surface, a cylindrical surface or a conical surface in point contact or line contact with the adjustment surfaces on an occlusal surface thereof. | 02-17-2011 |
| 20110045441 | ARTIFICIAL MOLAR TEETH - Maxillary molar teeth and mandibular molar teeth are formed so as to be different in intersection angles (vertical line angles) between vertical lines extending in a vertical direction to occlusal facets and occlusal planes. That is, the maxillary molar teeth and the mandibular molar teeth are formed so as to be different in intersection angles of vertical lines of the protrusive occlusal facet and retrusive occlusal facet respectively. The occlusal facets of at least one of buccal cusps of the maxillary molar teeth and lingual cusps of the mandibular molar teeth are designed so that at least one of the width in the mesiodistal direction and the width in the cuspal-cervical direction is smaller than the occlusal facets of the opposite cusps of the antagonist molar teeth. | 02-24-2011 |
