In‐Vitro Comparison of Tensile Bond Strength of Denture Adhesives on Denture Bases

<p>PURPOSE: To evaluate the tensile bond strength (TBS) of three cream denture adhesives and one wafer denture adhesive on three denture base materials at five time intervals up to 24 hours. METHODS: Fixodent (Proctor & Gamble™), Super Poligrip (GlaxoSmithKline™), Effergrip (Prestige Brands, Inc.™), and SeaBond (Combe™) were tested with the Instron testing machine on three denture base resin cylinder models fabricated from two heat‐polymerized (Lucitone 199 and SR Ivocap) and one visible lightcured, shade stable (Eclipse) acrylic resins. Laboratory prepared artificial saliva with mucin was used for the control study. In accordance with ADA specifications, the TBS was tested at 5 minutes, 3 hours, 6 hours, 12 hours and 24 hours after application of the adhesive. Maximum forces before failure were recorded in megapascals (MPa) and data subjected to a Two‐way ANOVA (P=. 05) using SPSS 19.0 software. RESULTS: All four adhesives revealed greater TBS than the control. However, Fixodent, Super Poligrip and SeaBond had higher TBS than Effergrip. All four adhesives showed greatest TBS at the 5‐minute interval and the least at the 12 and/or 24‐hour intervals. The three denture bases were significantly different with each adhesive (P<0.001). Lucitone 199 with the adhesives showed the greatest TBS followed by Ivocap and Eclipse. CONCLUSIONS: All four adhesives revealed greater TBS than the control and all four adhesives were strongest at the 5‐minute interval. On all three types of denture bases Effergrip produced significantly lower tensile bond strength and Fixodent produced significantly higher bond strength. At 24 hours, the greatest TBS adhesive‐base material combinations, in this study, were Fixodent on Lucitone 199, Fixodent on Eclipse, Fixodent on Ivocap and Super Poligrip on Ivocap.</p>
