  • Patent number: 10143542
    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.

  • Patent number: 8280542
    Abstract: A dental prosthesis is made by first forming a model of a patient's dentition. A three dimensional digital data corresponding to the surfaces of the model is then created. Based on this data, a three dimensional digital data file is then created substantially corresponding to the dental prosthesis to be manufactured. The three dimensional digital data of the dental prosthesis to be manufactured is next transmitted to automated prototyping equipment, and using the automated prototyping equipment, a wax pattern of the dental prosthesis is manufactured based upon this three dimensional digital data of the dental prosthesis. Finally, using this wax pattern in the lost wax investment casting process, the dental prosthesis is made. Prior to investment casting, marginal edges of the wax pattern are adjusted manually.
