ABSTRACT:
A dental core and post assembly for use in the formation of a dental core for the restoration of a tooth structure. The dental post assembly includes a support structure for positioning into a prepared tooth root to be restored. At least one leg depends from the support structure for insertion into an ancillary bore predrilled into the root adjacent a central bore predrilled through a canal in the tooth root. An axial aperture through the support structure permits a pin to be adjustably inserted through the axial aperture and into the central bore until it is seated in the central bore. The leg is contiguous with the pin. In one form the invention provides a burnout core and post for the direct technique of forming a post and core system. In another form, the invention provides an impression post for use in connection with the formation of an impression in the indirect technique of forming the core and post system.
