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. |
