Abstract
The invention disclosed herein relates to an efficient and inexpensive way to form dental clasps and fixed single unit temporary prostheses from molten thermoplastic resin. The apparatus and method allow a dental laboratory to make non-metallic clasps using an inexpensive handheld thermoplastic injection unit/gun that injects molten resin into a model of the clasp made from wax. A silicone putty matrix allows the resin to flow into a vacated wax model of the clasp. The time and money needed for this is much less than is needed to create such clasps using hot press equipment.
