Dental Implant, Superstructure, And Dental Prothesis

A dental prosthesis, comprising:

• a dental implant;
• a superstructure;
• and
• a fastening element configured to fasten the superstructure to the dental implant,
• the superstructure comprising an opening extending along a central longitudinal axis of the superstructure and having an interface for fixing the superstructure to the dental implant,
• wherein the interface comprises an extension that is arranged on a lower side of the superstructure, surrounds the opening and has a lateral surface which forms an outer side of the extension,
• wherein the lateral surface is interrupted by a recess which leads into the opening, and
• wherein the recess has two mutually opposite side flanks which, in a cross section oriented orthogonally with respect to the longitudinal axis, 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.
