A dental post for retaining a dental restoration in a secured position on a prepared tooth stub, the dental post including a cylindrical elongated pin having grooves disposed about the periphery thereof, the pin being insertable within a bore provided in the tooth stub. A head portion of the pin projects from the tooth stub to secure the restoration thereon. The head portion includes a substantially conical neck section from which projects a flattened tang. The tang is substantially wider than the diameter of the pin and is angularly oriented with respect to the elongated axis of the pin. The head portion provides improved retention of the superstructure upon the tooth stub and permits orientation of the tang in the same angled direction as the angular orientation of the tooth prosthesis so as to be centrally located within the tooth superstructure for improved retention and strength. |
