摘要： A dental abutment having an embedded part which is positioned and fixed in the embedding hole of a dental prosthesis., a 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 of the block. The dental abutment includes a gingiva contact part formed to having a conical shape on the intraoral side; a fitting part projecting toward the jawbone side from the jawbone-side contact surface of the gingiva contact part, 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 into an embedding hole. Three or more projections are formed on an outer peripheral surface of the embedded part so as to form a gap for a dental adhesive.

摘要： 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.

摘要： To provide a dental implant abutment (2) made of titanium, which is mounted on the intraoral side of a dental implant fixture (1) 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 made of titanium does not remarkably impair aesthetic property even when the intraoral portion of the dental implant abutment is seen through gingiva in a dental implant treatment as a treatment method to recover lost oral function of a lost tooth part. The dental implant abutment made of titanium is mounted on the intraoral side of a dental implant fixture being 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 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.
摘要翻译：为了提供一种由钛制成的牙科种植体基牙（2），其安装在植入颚骨中并成为人造牙根的牙科种植体固定装置（1）的口内侧上，穿过牙龈并变成上部结构的基部。作为用于恢复丢失的牙齿部分的失去的口腔功能的治疗方法，即使在牙齿植入物治疗中通过牙龈观察牙科种植体基牙的口腔部分时，由钛制成的牙科种植体基牙也不会显着损害美学性能。由钛制成的牙科种植体基牙安装在嵌入颚骨中并成为人造牙根的牙科种植体固定装置的口腔内侧，穿过牙龈并成为上部结构的基部。由钛制成的种植牙基台的表面被着色以具有40至44范围内的L *值，21至40范围内的a *值以及b *值在 - 20至10，它们由L * a * b *颜色系统表示。
