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

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 isobutyl 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.
