ABSTRACT:
A ring-like adjustment member having a plurality of adjustable elements is mounted in a tooth-encircling relationship with a prepared tooth having a finish line. Each element is adjustably movable so that its leading edges may be moved toward an attachment line defined by the neck of the tooth and its immediately adjacent gingival tissue below the visible gum line. The leading edges, after adjustment, define an impression line whose contour resembles the contour of the finish and/or attachment lines. Accurate custom-made impressions of the prepared tooth may be obtained. The adjustment member may also be mounted on the prepared tooth to assist in the formation of a temporary crown, and may further be mounted as a readily removable matrix on a tooth requiring filling.
