ABSTRACT:
A dental post system for use in the formation and retention of a dental restoration on a tooth stub. The system includes a dental post having an elongated cylindrical pin with a lower anchoring portion which is secured into a prepared bore in the tooth stub, and an upper end portion which projects from the tooth stub and is secured in a metallic core upon which the restoration is fabricated. An interlock arrangement coacts with the upper end portion to provide permanent securement of the metallic core on the cylindrical pin. The interlock arrangement prevents axial lift off of the metallic core from the dental post as well as preventing rotational displacement between the metallic core and the dental post. A core pattern is used to form the metallic core, where the core pattern can be fabricated from a preformed plastic core or can be built up directly onto the upper end portion when the dental post is disposed in the bore of the tooth stub.
