Shear adhesive strength tests were conducted to examine the adhesion of a newly developed light-polymerized denture base resin (LPR) to resin teeth and denture base materials. When LPR was bonded to these materials with a new light-activated bonding agent, the adhesive strength improved greatly. Adhesive strengths of LPR to denture base metals were greater than, or similar to, the metal adhesive autopolymerized resin containing 4-META. Compared with the metal adhesive heat-polymerizing resin, the LPR adhesive values were less when bonded to pure titanium but greater for 18-8 stainless steel and the gold-silver-palladium alloy.
