ABSTRACT:
A dental coping is set forth for placement over an abutment post that is attached to and protruding above a dental implant. The abutment post includes an outer surface with at least one structure for non-rotationally engaging a prosthetic tooth. The coping includes a base portion having an internally tapered surface for mating with a support surface of the implant. A wall extends away from the base portion for enveloping the abutment post. The wall includes at least one aperture for being aligned with and providing access to at least one of the non-rotational attachment engagement structures of the abutment post. The apertures are especially useful in the process of making the prosthetic tooth by allowing wax material to pass therethrough and engage the non-rotational features of an analog device replicating the abutment post such that a castable material will form antirotational features for mating with the antirotational features of the abutment post.
