Abstract
Several chairside hard resin reline materials have been introduced to improve the fit and function of existing denture bases. However, it is not known whether the bond strengths among the various chairside reline and denture base materials are significantly affected by their differences in chemical composition. This study evaluated the bond strengths of five chairside hard reline materials (Extoral VLC, Flexacryl Hard, Kooliner, Light Liner, and Triad Hi-Flow VLC reline material) to two different denture base resins (Lucitone 199 and Triad VLC) by use of a three-point transverse flexural test. The reline resins are representative of autopolymerizing, light- and dual-cured materials. The results indicate that Triad VLC reline resin with bonding agent gave the highest bond strengths to Triad VLC denture base resin. Light Liner reline resin gave the highest repair bond strengths to Lucitone 199 denture base resin.
