  • Patent number: 8777617
    Abstract: To provide a dental abutment having an embedded part embedded into an embedding hole of a block and fixed in the embedding hole. An uniform gap for a dental adhesive can be formed along an approximately entire circumference between an outer peripheral surface of the embedded part and an inner surface of the embedding hole. The dental abutment includes a gingiva contact part 1 having a forward-thicker truncated conical shape on the intraoral side; a fitting part 2 projecting toward the jawbone side from the jawbone-side contact surface 1a of the gingiva contact part 1, and fitted into an end part on the intraoral side of the implant fixture so as not to rotate; and an embedded part 3 to be embedded. Three or more projecting line parts 5 are formed on an outer peripheral surface 3a of the embedded part 3 so as to form the uniform gap.

  • Publication number: 20120252654
    Abstract: To provide a zirconia-based composite ceramic sintered compact capable of being colored to white appropriate for a dental prosthesis while maintaining its mechanical and physical properties, and also provide a method for producing the same. The method for producing the zirconia-based composite ceramic sintered compact includes semi-sintering a zirconia-alumina composite ceramic containing an alumina particle and a zirconia particle comprising of tetragonal zirconia containing ceria of 8 to 12 mol %, forming the composite ceramic; dipping the formed composite ceramic in a neodymium ion solution or complex solution; drying the dipped composite ceramic; and finally sintering it.

  • Publication number: 20120214132
    Abstract: To provide a dental implant abutment made of titanium, which is mounted on the intraoral side of a dental implant fixture embedded in a jawbone and coming to be an artificial tooth root, penetrates through gingiva, and comes to be a base of an upper structure. The dental implant abutment does not remarkably impair aesthetic property even when the intraoral portion of the dental implant abutment is seen through gingiva. The surface of the dental implant abutment made of titanium is colored to have the value of L* within a range from 40 to 44, the value of a* within a range from 21 to 40 and the value of b* within a range from ?20 to 10, which are represented by L*a*b* color system.

  • Publication number: 20040254261
    Abstract: To provide a one component dental composition in which a polymerzable compound having an acidic group is coexisted with a reducing agent such as a tertiary amine under the existence of water, and which is not cured with time during preservation, the dental composition comprises the polymerlizable compound having an acidic group, the reducing agent, water and an aluminum oxide powder, wherein it is preferable that 0.4 mol equivalent or less of the acidic group of the polymerizable compound having the acidic group and 0.05 mol equivalent or less of a reduction part of the reducing agent are contained per 100 m2 of a specific surface area of an aluminum oxide powder and that 5 to 35 weight parts of the polymerizable compound having the acidic group, 0.1 to 5 weight parts of the reducing agent, 10 to 55 weight parts of water, and 0.1 to 5 weight parts of the aluminum oxide powder are contained.
