Abstract: Our method applies a continuous pressure to an exterior of a denture setup during the polymerizing and shrinking of the plastic material forming a portion of our denture. The direction from which shrinkage occurs is controlled using a constant pressure of water. Application of at least 300 pounds per square inch (psi) of water pressure during polymerization continually forces a critical inside denture surface being formed against a master model surface to allow the major shrinkage to take place on a less critical outside denture surface, thereby reducing distortion to the interior (fitted) portion of the denture. This pressure reduces the size of the air bubbles to maximize the density of the polymerized denture material, thereby lowering oral fluid sorption into our denture. Thus our denture overall is a stronger, better fitting, durable product that addresses the esthetic, health and hygiene issues presented by conventional dentures.
