Abstract: A process for producing dental devices such as teeth is disclosed. Specifically, a process for producing gold dental devices, such as gold denture teeth, is disclosed. The process includes the production of an injection mold based on an impression or mold of a target tooth. The injection mold can then be utilized to produce a hardened polymeric precursor of the product device. In particular, a hardened precursor can be produced from pure polypropylene. The precursor can be used as a model to produce an investment casting mold. The desired product material, for example a gold alloy, can then be cast in the investment casting mold by methods known in the art to produce the final product.
