ABSTRACT:
A holding device for a dental prosthetic structure having an externally threaded elongated post which can be inserted within a bore in a tooth stub. An elongated slot is formed on the outer surface of the post. A retaining nut threads onto the post and includes a plurality of pointed tabs which serve as restorative material retainers. One of the tabs enters into the slot to thereby prevent rotation of the retaining nut with respect to the post. A screw may be threaded into the tooth stub to prevent rotation of the retaining nut relative to the tooth stub.
