Abstract

The invention provides a curable system and method of making a dental prosthesis. The method of making a dental prosthesis includes providing a one component denture base resin composition which is polymerizable by microwave energy. The one component denture base resin composition is injected into a mold enclosed by a flask having a body wall which is substantially transparent to the microwave energy. The curable system includes microwave energy sensitive initiators and polymerizables (meth)acrylate Monomers having molecular weights preferably between 400 and 20,000. The initiators are adapted to initiate polymerization of the polymerizable Monomers by application of microwave energy to the flask. The initiators are adapted to remain stable and not initiate polymerization of the Monomers for at least one year at 23° C. in the absence of microwave energy.
