Abstract:
1. A dental restoration comprising: a one piece integrally formed substructure body having an open distal end, a closed proximal occlusal end and a side wall extending between said distal and proximal ends, said side wall including a generally uniform outer surface, said substructure body further including a support structure protruding from said outer surface of said side wall at a location spaced from, but generally near, said occlusal end of the substructure body, said support structure having a smooth shape and generally encircling the entire periphery of the substructure body, wherein the substructure body forms a hollow framework for receiving a dental preparation, and a veneer formed over and contacting the outer surface of the side wall, the support structure and the occlusal end of said substructure body; wherein said support structure is located generally proximate to the location of greatest occlusal stress and protrudes a distance from the surface of the side wall surface so as to provide support for said veneer that reduces the sheer stress exerted on said veneer.
