ABSTRACT:
A method and system for preparing a cast post and core in a dental root canal procedure is provided. The method comprises the steps of removing the root canal material from the tooth; cutting out a post-hole in the tooth having a substantially uniform width; cutting out at least one annular tier along the hole; placing a burn-out post having at least one flange into the post-hole so that the flange is seated on the annular tier; applying an acrylic resin onto the tooth and over the burn-out post in order to form a core, and finally removing the core with the burn-out post from the tooth in order to form a casting.
