Effect of three different polymerization techniques on the tensile bond strength between acrylic teeth and denture base

Bond failures between artificial teeth and denture bases represent a problem for rehabilitation success. Many factors are responsible for these failure; tooth types and brands, resin types and brands, stress distribution temperature of processing resin stage and processing variables. Acrylic denture base resin traditionally has been polymerized in temperature controlled water bath. Denture base polymerization through microwave processing was introduced by Nishii 1968 and has become increasingly popular as an alternative to conventional heat polymerization. an additional method of polymerization is recently performed by light cure. The effect of these methods of polymerization, heat, microwave and light cure, eon the bond strength between acrylic teeth and denture base was investigate
