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.
