Abstract
A composite dowel pin on which a tooth form may be cast for use in a dental model comprises a body member of synthetic resin tapering to a reduced cross section at one end and a generally cylindrical metal pin extending longitudinally through and outwardly of at least the other end of the body member and securely engaged therewith. The projecting portion of the pin provides a head upon which the tooth form may be cast. Preferably the body member is generally frustoconical in configuration with a planar surface and diametrically opposed rib both extending the length thereof; the pin extends beyond the narrow end and has a notch adjacent its point of exit.
