Method of installing a post in a tooth having a metal obturator therein including the steps of drilling a borehole in the tooth with a tubular burr having a tubular opening therein of internal diameter at least slightly greater than the diameter of the obturator to thereby provide a borehole of selected internal diameter having the metal obturator remaining essentially therein, the obturator serving to assist in the guiding of the burr and inserting a tubular post into the borehole, the post receiving the metal obturator therein, the post extending partially above the top of the tooth for attachment of a crown or the like. |
