Abstract
The invention relates to components for an improved system for pick-up impression making at a dental implantation site, including an abutment, an abutment replica and an impression coping. The invention also relates to a series of abutments and to a set comprising an abutment and an impression coping. The impression coping has a through passage extending from a coronal end to an apical end of the impression coping and includes an abutment surrounding region for surrounding the abutment. The abutment surrounding region has a coronal end, an apical end and an inner wall. The inner wall includes at least one abutment contact surface for contact with the abutment, and at least one space forming surface for being spaced apart from the abutment in order to provide a space between the space forming surface and the abutment.
