Abstract

An arrangement including a spacer element operative to support a superstructure and including a first passage and a second passage. The second passage is operative to permit mechanical anchoring of the holder. A first screw is operative to screw the spacer element into an implant. During an initial stage of insertion the first passage is operative to receive the first screw such that a center axis of the first screw is inclined in relation to a direction of screwing of the first screw. During a final stage of insertion the first passage permits the first screw to tilt such that the center axis of the first screw substantially coincides with the direction of screwing. A holder is operative to hold the spacer element. The holder substantially prevents the first screw from leaving the position it has assumed during the final stage of insertion. A second screw is operative to screw the superstructure onto the spacer element.
