ABSTRACT:
A device for transferring the direction and position of a dental implant or its extension element, such as a spacer element, to a work model, includes a base part and an elongate upper part projecting from the base part. The device is made of an elastic material so that clamp fitting is obtained between the base part and the implant or its extension element. The upper part has a geometry which provides for retention in the surrounding impression compound and has break notches so that it can easily be shortened.
