The proximal end of the screw channel part (51) is bowl shaped, such that the inner bottom surface has a concave shape and its outer bottom surface (55) has a 10 convex shape. The screw hole of the screw member seat (54) is a long hole. The implant cooperating part (52A, B) comprises a collar-shaped lower implant cooperating part (52A) to be connected to a dental implant (60) and a collar-shaped upper implant cooperating part (52B). The 15 lower implant cooperating part (52A) has a distal concave seat (58), and said upper implant cooperating part (52B) has a proximal convex bottom surface (57) with a radius corresponding to the radius of the concave seat (58) of the lower implant cooperating part (52A) to form a first 20 ball joint (57, 58). The upper implant cooperating part (52B) has a distal concave seat (56) with a radius corresponding to the radius of the outer bottom surface (55) of the screw channel part (51) to form a second ball joint (55, 56). The two ball joints have the effect that 25 the screw channel part (51) may be tilted/angled and transferred sideways in relation to a central axis of the lower implant cooperation part (52A).
