    摘要: A dental implant is provided that is capable of reliably preventing elution of metal when the dental implant is applied within an oral cavity and capable of reliably preventing the occurrence of mismatching (bumpy occlusion or the like) when the dental implant is fixed in place. The dental implant includes an abutment comprising a titanium member composed of a body made from titanium or titanium alloy and having a recess, and a ceramic member composed of oxide-based ceramic and having a protrusion fitted within the recess. In a pre-sintered state, the recess has a first surface shape providing a clearance between the recess and the protrusion inserted therein. In a post-sintered state, the recess has a second surface shape corresponding to a surface shape of the protrusion so that the protrusion is in close contact with and fitted to the recess.

    摘要: A dental implant capable of reliably preventing elution of metal when the dental implant is applied within an oral cavity and capable of reliably preventing occurrence of mismatching (bumpy occlusion or the like) when the dental implant is fixed in place, and a method for manufacturing the dental implant are provided. In the method for manufacturing a dental implant including an abutment, the abutment is manufactured through the steps including a titanium molded body production step for molding a titanium molded body composition to obtain a titanium molded body, an assembling step for assembling the titanium molded body and a ceramic member together to obtain an assembled body, a degreasing step for degreasing the assembled body so that the titanium molded body is transformed into a titanium degreased body, and a sintering step for sintering the assembled body to transform the titanium degreased body into a titanium member so that the titanium member is firmly fixed to the ceramic member.
