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. |
