Abstract: A screw channel directing device for a dental superstructure includes a screw channel part and an implant cooperating part, the former having a screw member seat with an elongated screw hole in the proximal end. The proximal end of the screw channel part is bowl shaped, having a convex outer bottom. The implant cooperating part comprises a collar-shaped lower implant cooperating part to be connected to a dental implant and a collar-shaped upper implant cooperating part. The lower implant cooperating part and said upper implant cooperating part form a first ball joint. The upper implant cooperating part has a distal concave seat with a radius corresponding to the radius of the outer bottom surface of the screw channel part to form a second ball joint.

Abstract: A dental superstructure attaching system for use with a dental implant includes a longitudinal member being connectable with an implant or an implant connecting member via an at least partially curved interface area. The longitudinal member includes a main member forming the lingual part of said longitudinal member, and a lever member forming the buccal or labial part of said longitudinal member. The longitudinal member includes means for urging said lever member and said main member away from each other, such that said longitudinal member is secured to said implant or implant connecting member. The system includes a casing (200) for attachment to a dental superstructure on the outer surface of the casing (200), said casing (200) having a cavity (201) for housing the longitudinal member (102), such that when urging said lever member (102b) and said main member (102a) away from each other, the longitudinal member (102) is secured in said cavity (201).

Abstract: The present disclosure provides a dental bridge intermediary structure (20) comprising a superstructure (200) and a connection piece (210), as well as connection piece for a dental bridge intermediary structure (20). A method for producing a dental bridge superstructure (200) is also provided.

Abstract: A dental superstructure, and a manufacturing method thereof, comprising a screw-channel (1), through which screw-channel a screw member is to be inserted, and a screw member seat (3), for providing support to the head of said screw member during fixation of said dental superstructure to a spacer element or an implant (5), are provided. Said dental superstructure is provided with a central axis of said screw-channel (1) and a central axis of said second mouth (4) that at least partly do not coincide. A manufacturing method thereof, a screw-member, and a screwdriver are also provided.
