Abstract

Introduction: Optimal bond between denture base and the soft liner is necessary as adhesion failure is the most common problem encountered clinically. Hence, this study evaluated the tensile bond strength of two commercially available temporary soft liners to different types of denture base resins. Materials and Methods: Prepared wax specimens were heat cured to get 16 samples of each type of denture base resin specimens (DPI, Trevalon, and Trevalon HI). A 3 mm section of acrylic denture base material from the center of each specimen was removed, and the two parts of the fragmented specimens were then repositioned into the aluminum die for the application of temporary soft liners (Group A, Viscogel and Group B, GC tissue conditioner). The specimens were tested for bond strength using universal testing machine and debonded surfaces were observed under a stereomicroscope for analysis of failure. Results: Viscogel showed the highest tensile bond strength with all three different types of denture base resins. Viscogel was significantly superior over GC tissue conditioner. Trevalon exhibited better bond strength results with both Viscogel and GC temporary soft liners as compared to other two types of denture base resins. Conclusion: Viscogel, a temporary soft liner, showed better bond strength compared to GC soft liner in bonding conventional and modified denture base resins.
