ABSTRACT:
The present invention consists of a pre-made reinforcement device having a core for receiving a prosthetic crown. A vertical axis, horizontal plane anti-rotational device interconnects the post-and-core and is positioned within indexing recesses extending from a hole in the pretreated tooth. An advantageous locking of the reinforcement device results from the post, core and anti-rotational device combination.
