Effect of Nanoparticles Incorporated to Denture Bases on Somephysicomechnicalproperties

Objective: To assess flexural strength, color stability, surface roughness of heat cured acrylic and thermoplastic resins materials after addition of (Ag Z the flexural strength decrease with increasing ZrONPs concentrations. Color showed significant changes for acrylic group than flexible group with Ag modified subgroup, but for ZrO modified subgroups, flexible group recorded significant changes than acrylic resin group. Finally, there were non-significant differences in surface roughness occurred with all groups with different nano-particle type or concentration. Conclusion: flexural strength depends on several factors including; the type of denture base, types and concentrations of nanoparticles used. Also significant color differences were detected between control group and other tested groups that were clinically unacceptable. Surface roughness of all groups showed non-significant differences.
