1. A dental implant for a dental prosthesis, comprising:
an external thread arranged on an outside of the dental implant for fastening the dental implant to a jawbone;
an opening extending along a longitudinal axis of the dental implant, wherein an internal thread for fastening a superstructure to the dental implant is arranged in the opening; and
an interface arranged at a front end of the dental implant for fastening the super-structure to the dental implant;
wherein the interface comprises a convex, rounded curvature extending around the longitudinal axis over an angular range of at least 90°, and a support surface arranged radially outwardly relative to the convex curvature, wherein the support surface has at least one annular portion that is oriented transversely to the longitudinal axis, and
wherein, in a longitudinal cross section along the longitudinal axis of the dental implant, a tangent, that lies in the longitudinal cross section and is oriented tangentially to a radially outer edge of the convex curvature that faces the annular portion of the support surface, is oriented parallel to or coplanar with the annular portion of the support surface.
