Abstract: A threaded dental implant to be screwed into a jawbone for supporting at least one abutment and/or a dental superstructure, and having a socket arrangement with a first section and a second section with respective geometrical profiles around a longitudinal center axis of the implant. The first section cooperates with the abutment for securing the abutment in a determined position in the implant. The second section cooperates with an insertion tool for screwing the implant into the jawbone. The first section includes an annular coronal contact surface on top of an opening centric at a coronal end of the implant, followed in an apical direction by a first tapered section having a diameter decreasing in the apical direction, by a first cylindrical section, by first anti-rotational elements and by a threaded section.

Abstract: Dental implant having a socket arrangement having the shape of a regular octagon which is partly interrupted by outwardly extending notches being parallel or parallel and partly inclined with respect to the longitudinal center axis of the implant, the inclination being such as to taper inwardly from their coronal end, wherein interrupting and outwardly extending ridges extending from the notches in an apical direction of the dental implant, first contact surfaces being adapted to engage and rotationally secure an abutment, and wherein second contact surfaces extend from the notches within the ridges in the direction of the longitudinal center axis, the second contact surfaces being adapted to engage with an insertion tool; and wherein the notches are positioned at sides or at corners of the regular octagon.
