Abstract
A process for preparing a dental prosthesis is disclosed, including preparing a wax pattern of an objective dental prosthesis based on a duplicated model having an intraoral shape, investing the wax pattern in an investment material, and removing the wax pattern to prepare a mold, wherein a composite resin is charged under pressure into the mold, and the composite resin is cured under heat and pressure, the process of the present invention enables one to obtain a dental prosthesis that has suitable esthetics and superior mechanical properties and free from fear of pulp irritation by the unpolymerized monomer, and particularly suitable for the preparation of inlays, crowns, etc.
Claims8
A process, comprising
- preparing a wax pattern of an objective dental prosthesis based on a duplicated model having an intraoral shape;
- investing the wax pattern in an investment material;
- removing the wax pattern to prepare a mold;
- charging a composite resin into the mold under a pressure of from 0.5 to 30 MPa and at a temperature of from 60 to 90° C.;
- and
- curing the composite resin under heat and pressure, wherein the composite resin comprises a (meth)acrylate compounded with one or more than two inorganic, organic, or inorganic-organic composite fillers and further with a heat polymerization catalyst.
