Abstract: A tooth dowel 10 has a shaft 11 and a coronal restoration frame or head 12 enlarged to provide support for substantially all parts of a total restoration and so constructed as to be relatively readily reducible to fit a restoration of a tooth requiring only a partial restoration. The head includes segmental finger elements 14 adapted to be removed to reduce the size of the head, e.g. by a small disc cutting wheel or pair of snips. A damaged tooth can be rebuilt by (a) obturating (stopping) the root canal, (b) enlarging the coronal portion of the canal, (c) reducing the segments of this tooth dowel appropriately, (d) fixing the so reduced dowel in the canal, and either (e) immediately reducing any remaining coronal tooth structure and fixing a crown on the so reduced tooth and dowel head, or (e1) fabricating a restoration on the dowel head and any remaining tooth structure (FIGS. 2A, 2B), and optionally (e2) reducing the restoration to a core (FIGS. 3A, 3B) and fixing a crown thereon at a later date.
