Abstract
Apparatus and method for producing a permanent metal post and core adjusted angularly in order to result in a prosthesis aligned in parallel relation to surrounding teeth and prostheses. A bendable post and core assembly is placed in a conventional anchor. The post is bent to a precise desired angle with respect to the core, and cemented in this position. A ceramic mold is formed around the cemented post and core. The post and core, which is preferably fabricated from a synthetic organic polymer which melts at a temperature below 1,400.degree. F., is then heated and evacuated from the mold. A permanent post and core is then cast in the mold from a suitable material, such as gold. Optionally, a sleeve which is configured to slip over and closely conform to the post is employed, either to increase the diameter of the core prior to forming the mold, or to assist in fabricating the denture after the permanent post and core is completed.
