Effects of different high alkyl methacrylate monomers on tensile bond strength between resilient liner and acrylic resin

Abstract In the present study, tensile bond strength between an acrylic resin and a resilient denture liner, Molloplast B, was studied. To enhance the bonding capacity between these materials, acrylic resin surface was modified using ethyl methacrylate, iso-butyl methacrylate or tert-butyl methacrylate monomers. Changes on the modified surfaces were investigated by Fourier transform infrared spectroscopy with attenuated total reflectance. Only the modifications by iso-butyl methacrylate application appeared to have an increasing effect on the tensile bond strength value. Ethyl methacrylate and tert-butyl methacrylate, however, had a lowering effect on this value.
