Shear bond strength of three silicone lining materials bonded to heat-cured denture resin

This research compared the adhesive strength of three resilient denture lining materials cured with two different curing modes: autopolymerized (Mollosil plus, GC Reline Soft), and conventional laboratory processing (Molloplast-B); bonded to heat-cured acrylic resin. The findings showed that all the lining materials were acceptable for clinical use; there were no statistically significant differences among the bond strengths of the studied silicone materials. However, the bond strength became higher when Molloplast-B was applied to unpolymerized polymethyl methacrylate PMMA and processed together than it was applied to polymerized PMMA.
