Objective: One problem with the soft lining material is that it detaches from the acrylic base of dentures after a particular time period. So, the aim of this work was to evaluate how adding Montmorillonite nano clay would affect the soft lining material's shear bond strength and surface hardness.
Materials and Methods: The heat-cured acrylic denture material for the control group, polymer reinforced with (0.25%,0.5% by wt.) of montmorillonite nanoparticles for experimental groups was used in this study. For the shear bond strength test 60 blocks of acrylic-based material were constructed, each pair connected with soft lining material, the other 30 specimens for the surface hardness tests were carried out. to be tested with a shore A durometer. The data were statistically examined using the One-Way ANOVA test and Bonferroni multiple comparisons test.
Result: 0.5% by weight MMTNPS should significantly increase in both shear bonding strength and surface hardness .
Conclusion: MMTNPs were remarkably successful in improving the the strength of the shear connection between acrylic and soft liners.
