Method of fabricating artificial dentures

A method of fabricating a finished artificial denture, comprising:

• (1) making a precise provisional denture comprising a denture base and a plurality of artificial teeth thereon, the denture base having a concave surface conforming to the actual shape of an edentulous ridge in a patient's mouth by taking an impression of the endentulous ridge, forming a jaw model from the impression, attaching a synthetic resin compound or wax onto the jaw model to provide a provisional denture base for positioning artificial teeth thereon, attaching artificial teeth to the provisional denture base, removing the denture base with the attached teeth from the jaw model to provide a provisional denture, applying a predetermined quantity of tissue treatment material to the concave surface of the provisional denture base and adjusting the provisional denture base while it is in the patient's mouth thereby forming the precise provisional denture with an actual shape;
• (2) making a precise jaw model having a convex surface from the concave surface of the denture base of the precise provisional denture such that the precise jaw model provides for a wide clearance during subsequent molding of an artificial denture;
• (3) forming a block of plaster or other hardenable material having a recess therein that conforms to the actual shape of the precise provisional denture, the artificial teeth having their tips extending into the block and their roots extending into the recess having a concave surface;
• (4) filling a synthetic resin compound into the recess of the block;
• (5) forcing the precise jaw model to move into the recess of the block to mold the synthetic resin compound therein into the artificial denture;
• (6) subjecting the synthetic resin compound to a polymerization reaction to cause the compound to cure and solidly fill a plenum defined by the convex surface of the precise jaw model and the concave surface in the recess of the block;
• and
• (7) breaking the block apart upon solidification of the synthetic resin compound to provide a finished denture,
• wherein synthetic resin compound spilling over the plenum during polymerization escapes into the wide clearance formed between the precise jaw model and the block thereby avoiding any movement of the precise jaw model upwardly away from the block, and thereby resulting in the finished denture conforming to the actual shape of the precise provisional denture.
