Abstract: Dental implant and superstructure each with an interface that allows direct attachment of the superstructure to the dental implant without the use of an abutment. The dental implant comprises an anti-rotation element that is arranged in the opening and is configured to prevent the superstructure from rotating about a longitudinal axis relative to the dental implant. The superstructure comprises an interface corresponding to the anti-rotation element, having a recess with two mutually opposite side flanks which are at a first distance from each other in a first region and, in a second region which is at a greater distance from the longitudinal axis than the first region, are at a second distance from each other, the second distance being smaller than the first distance.

Abstract: Dental implant comprising an implant body having on an outer side an external thread for fastening the dental implant to a jaw bone and having an opening extending along a longitudinal axis of the dental implant. The opening comprises an internal thread for fastening a superstructure to the dental implant. The implant body further comprises an interface for fastening the superstructure to the dental implant, which interface is arranged at a front end of the implant body. The dental implant further comprises an anti-rotation element which is configured to prevent rotation of the superstructure around the longitudinal axis relative to the dental implant, wherein the anti-rotation element is configured as a component separate from the implant body, which is attached to the implant body in an area of the interface.

Abstract: Dental prosthesis comprising a dental implant comprising an external thread for screwing the dental implant into a jawbone and an internal thread arranged inside the dental implant. The dental prosthesis further comprises a superstructure having an internal bore and a screw for fastening the superstructure to the dental implant. The screw has a screw head with a cylindrical or conical lateral surface and a shank which adjoins a lower end of the screw head and on which an external thread is arranged. In an assembled state of the dental prosthesis, the screw is inserted through the internal bore of the superstructure into the dental implant and the external thread of the screw engages the internal thread of the dental implant. The screw head comprises a convexly rounded chin between the cylindrical or conical lateral surface and its lower end, with which chin the screw abuts the superstructure in the internal bore in the assembled state of the dental prosthesis.

Abstract: A casting abutment for a dental implant comprising: an apical socket portion, a transition portion bordering coronally on the socket portion, an occlusal portion bordering coronally on the transition portion and having an apical lower rim, wherein the occlusal portion, starting from its lower rim, is provided on its peripheral surface with an area having indentations, whose crests face the transition portion.

Abstract: Casting abutment for a dental implant that includes an apical socket portion, a transition portion bordering coronally on the socket portion, and an occlusal portion bordering coronally on the transition portion, having an apical circumferential collar area. The collar area is provided with an axially closer lying first circumferential platform and with at least two adjacent circumferential step-like areas, wherein the largest diameter of a first step-like area is smaller than the smallest diameter of a second step-like area the second step-like area lying apically with respect to the first step-like area.

Abstract: Impression post for a dental implant, having a sleeve-shaped impression cap (4) with a coupling section (16) configured to be connected to the dental implant (20), and a substantially cylindrical recess (6) extending in the longitudinal direction of the impression cap (4) and an attachment element (8) engaging through the recess (6) for attaching the impression cap (4) on the dental implant (20). The impression cap (4) has an inner sleeve (10) and an outer sleeve (12) radially surrounding said inner sleeve on the outside, which outer sleeve is detachably connected to the inner sleeve (10), and the coupling section (16) is at least partly an element of the inner sleeve (10).
