Date Sep. 26, 1996An enossal single tooth implant for a fixed dental prosthesis includes an essentially cylindrical base member which is insertable into a bore introduced into a jaw bone and which has a blind bore open toward one coronal end to form a face edge, a spacer sleeve attached in an anti-twist fashion to the face edge of the member, an implant post directly or indirectly introduced into the blind bore of the base member and at least partially penetrating the spacer sleeve. The spacer sleeve has a circumferential surface which forms part of a fastening head for the dental prosthesis and has an annular joining shoulder for engaging an edge of the prosthesis that has a peripherally varying spacing from the face edge of the base member to allow for adaptation to the anatomical conditions.
