<P>PROBLEM TO BE SOLVED: To provide a dental abutment whose embedded part is embedded into an embedding hole of a cutting block (dental prosthesis) and bonded and fixed in the embedding hole, in which a uniform gap for dental adhesive insertion is formed over the almost entire periphery between the outer peripheral surface of the embedded part and the inner surface of the embedding hole of the cutting block. <P>SOLUTION: 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 an implant fixture so as not to rotate; and an embedded part 3 to be embedded into the embedding hole of a cutting block made of ceramics. Three or more projecting line parts 5 are formed on the outer peripheral surface 3a of the embedded part 3 so as to form the uniform gap for a dental adhesive over the almost entire periphery between the inner surface of the embedding hole of the cutting block and the outer peripheral surface 3a of the embedded part 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
