Abstract
Abstract A tooth replacement is formed by reconstructing a defective tooth in place in the mouth; extracting the reconstructed tooth; forming a die to shape an artificial tooth using the extracted tooth as a model; making a mold from the die; filling the mold with a pharmaceutically-acceptable resin; curing or hardening the resin; extracting the thus-formed tooth from the mold; and inserting the artificial tooth thus formed into the place formerly occupied by the extracted tooth to permit the jaw to grow around and seat the root of the artificial tooth.
