An impression coping for transferring the inclination and position of a dental implant fixture or abutment to a working model has a ,base portion which provides for rotational locking to a fixture head or an abutment and an elongated upper part projecting from said base portion to provide for retention in a surrounding impression mould. The entire impression coping is made of an elastic material so that a clamp fitting is obtained between the base portion and the fixture head or ,abutment. The base portion comprises a downwardly projecting, unthreaded guide pin adapted for insertion into the internal bore in the fixture head or abutment during installation of the impression coping, thereby facilitating the centering and positioning of the coping during placement.
