Abstract
A technique of fitting prosthetic teeth whereby a hole is drilled and a screw compatible with the bone of the jaw bone is located within the hole. The screw is characterized by having from the head end thereof a hole into which the post which is to fit the prosthetic tooth thereto is receivable. The method then allows the post to be located for the taking of impressions and for the subsequent removal of the post for refitting after the prosthetic tooth has been prepared and has been associated with portions of said post. Ideally the post and the tooth are only fitted after a suitable healing period following the screwing of the screw. The invention also consists in apparatus and tools related to such a method.
