Purpose of the study: To determine the tensile bond strength of three commercially available soft liners to a polymethyl methacrylate denture base resin, to help the clinicians to select the liner for their patients, and to provide a comparative database when new materials are introduced. Basic procedures: In this study, tensile bond test was considered a good method of investigating and comparing the bond strength of three resilient lining materials, because it gives information on the strength of the bond in comparison to the tensile strength of the material. Main findings: The tensile bond strength of SuperSoft (acrylic-based liner) was better compared to Molloplast B (silicone-based liner) and Mucopren (silicone-based liner). Principle conclusion: The tensile test used in this study was effective in evaluating and comparing the tensile bond strength of the three liners. Factors such as processing methods, water sorption, bonding agents, changes in compliance, changes in the bond strength in the harsh oral environment, and chemistry of the material need further investigations to increase the serviceable life of the material.
