Abstract:
A system and method for fabricating dental crowns and bridgework includes the steps of: selecting one or more prototype teeth; forming a mold around the prototype teeth using a soft flexible material; placing the mold within a model of a patient's teeth; pressing the uppers and lowers of the model together to establish the bite; removing the prototype teeth from the mold; adding wet porcelain to the inside walls of the mold and vibrating the mold to create the incisal; adding wet porcelain to create the body; pressing framework into the uncured body; vibrating the mold and removing moisture; allowing the porcelain to dry and removing the molded porcelain crown or bridgework from the mold; trimming off excess porcelain and adding porcelain to the margin area as needed; baking the crown or bridgework in an oven and removing when half cured; and carving and shaping the half cured porcelain.

Claim (Index 1):
A method for fabricating dental crowns and bridgework comprising the steps of:\n selecting at least one prototype tooth; forming a mold around the selected prototype tooth using a soft, pliable molding material; placing the mold within a prefabricated model of a patient's teeth, wherein the model includes upper teeth and lower teeth that are a replica of the patient's upper teeth and the patient's lower teeth; moving the upper teeth and the lower teeth of the model together and causing the mold to be pressed against the opposing teeth of the model to establish the bite of the opposing teeth; removing the at least one prototype tooth from the mold to provide a mold cavity for forming the dental crown or bridgework; applying wet porcelain material to the inside walls of mold cavity; vibrating the mold to create a thin layer of the porcelain material that forms an incisal of the crown or bridgework; adding wet porcelain to at least partially fill the formed incisal and thereby providing a body of the crown or bridgework; pressing prefabricated framework into the wet porcelain that provides the body; vibrating the mold and removing moisture from the wet porcelain; allowing the porcelain to dry; removing the molded porcelain crown or bridgework from the mold; placing the molded crown or bridgework in a porcelain oven and baking the molded crown or bridgework until the porcelain material is between 40% and 70% cured; removing the molded crown or bridgework from the oven with the porcelain material partially cured; and carving and shaping the molded crown or bridgework to final form.
