Abstract: A system, an abutment, a dental implant, kits and a method for implanting a prosthesis onto a jaw of a patient. The proximal end of the abutments is a flat connection of a predefined shape that is circularly symmetrical with a proximad decreasing radius. The prosthesis is attached to the distal ends of the abutments, and each abutment corresponds to a dental implant in the jaw. The dental implants are not all parallel to each other and may form any angle between them. The flat connection allows substantial tolerance in attaching the prosthesis to the dental implants. The predefined form may be a proximal disc connected to a distal truncated cone, wherein the proximal disc is congruent to the proximal face of the truncated cone. One system comprises abutments, dental implants, elastic supporting elements and extension elements.

Abstract: A system comprising a dental interface device and a dental implant. The interface device provides an interface between a dental abutment and the implant allowing connecting the implant to the abutment. The interface device may comprise a shank and a polygonal connector, where the connector extends from one end of the shank. The connector may comprise sections forming the polygonal shape where the implant may comprise a polygonal receptacle, which is a cavity designed to receive the polygonal connector of the interface device. The outer dimensions of the connector may be slightly larger than the corresponding inner dimensions of the polygonal receptacle. The sections can bend inwardly towards the center of the connector when inserted to the receptacle, and return to an unbent position once the connector is inside the receptacle, thereby applying pressure upon the inner walls of the receptacle, thereby securing said connector to the receptacle and implant.
