ABSTRACT:
The invention relates to a tool for establishing correct interproximal contact between a tooth that has been bored out and the cavity filled with plastic filling, and an adjacent tooth with a contact surface directed towards the bored out tooth referred to, with plastic filling. The tool is provided with two outer pins and a central pin. The outer pins create stability for the tool, when a head of the tool, and from where the pins extend, is arranged in the bored out cavity. The central pin ensures, together with the outer pins and facing outs between the pins, that it is possible to establish the correct interproximal contact for the plastic filling against the contact surface of the adjacent tooth.
