Abstract

This invention pertains to a method and apparatus to fabricate economical full arch unitary upper and lower sets of artificial teeth for use in preparing dentures for edentulous dental patients and attaching said sets of teeth to denture base material by a process developed for the purpose of utilizing these sets of teeth and converting them into finished upper and lower dentures by the use of a specialized apparatus. The process and apparatus, per se, are the subject of another related application and eliminates the conventional procedure of mounting individual artificial teeth in the normal process of fabricating dentures.
