Construction of denture bases from pour resins.
Satisfactory dentures can be produced from pour resins at a considerable saving of processing time. The problems of porosity, voids, and heavy anterior tooth contact resulting from shrinkage of the resin during curing present difficulties which must be understood to be compensated for. The use of alginate and a recently introduced modified gypsum product as investing media, as well as centrifugation of the pour resin into the flask, offer no significant advantages over the originally introduced procedure. Further critical research will conceivably improve the pour resins and the corresponding processing techniques to the point that they can challenge heat-curing resins for the largest percentage of denture bases.
