ABSTRACT:
The invention relates to a subgingival jaw implant with an anchor body 4 which is made of metal material and at whose one end there is a surface 5 which is provided with a profile for engagement of a screwing instrument and on which a tooth replacement support 7 with a corresponding mating surface 14 can be supported. In order to permit particularly good incorporation of the jaw implant from the periodontal point of view, the invention provides that the surface 5 has a crest 12 and two flanks 12a, 12b descending therefrom, and the maximum diameter D1 of the tooth replacement support 7 is equal to or smaller than the maximum diameter D2 of the surface 5.
