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.

Dental implant, superstructure, and dental prothesis

A dental implant having 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 includes 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 has 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.
