Abstract: A fastening system (100) for a dental implant (30) comprising a ball shaped portion (31), wherein the fastening system (100) comprises a body (12) having a seat (10, 20) forming a cavity. The fastening system is characterized in that the body (12) comprises at least two parts (10a, 10b, 20a, 20b) together forming the seat (10, 20). The parts (10a, 10b, 20a, 20b) are arranged such that the seat (10, 20) can engage around the ball shaped portion (31) of the dental implant (30) and in that the seat (10, 20) is movable between a first position in which the parts (10a, 10b, 20a, 20b) are allowed to move relative each other, and a second position in which the parts (10a, 10b, 20a, 20b) are prevented from moving relative each other.

Abstract: This invention pertains to a superstructure (300) for a dental implant. The superstructure comprises a fastening portion (30) with a joint socket in form of a spherically shaped cavity with a fastening surface (32), and a main portion (31). This superstructure (300) is intended to be joined to an osseointegrated dental implant via the fastening portion (30). The main portion (31) comprises a lead-through (110) for receiving a sleeve (111) or a screw hole (55), wherein part of said lead-through (110) or part of said screw hole (55) forms an opening in the fastening surface (32), such that there is a perpendicularly distance between the center of the spherical cavity and the central axis of the lead-through (110) or of the screw hole (55).
