Effect of plasma treatment on the bond of soft denture liner to conventional and high impact acrylic denture materials

Background: The main drawback of soft lining materials was that they debonded from the denture base after a certain period usage. Therefore, purpose this research to determine impact oxygen and argon plasma treatment on shear bonding strength liners two different kinds materials: conventional acrylic resin high resin. Materials Methods: Heat cure blocks (40 for each group) were prepared. A liner connected final test specimen material. Shear bond (SBS) assessed using universal testing machine. Additional also prepared analyzing Vickers microhardness, contact angle, FTIR AFM. results statistically analyzed paired-sample T-test independent-samples (α=0.05). Results: showed highly significant increase in SBS following with highest mean value observed treated specimen. Along rise wettability, while microhardness preserved. Conclusion: In conclusion, significantly effective enhancing between materials.
