Compressive Strength of Alginate Impression Material Incorporated with Silver and Zirconium Oxide Nanoparticles

Aims: To investigate the effect of adding nanoparticles on compressive strength alginate impression material. Materials and Methods: In this study, two types were added to materials: silver zirconium oxide at four concentrations: 0.5 %, 1%, 2%, 5% by weight. Compressive was tested for 45 samples made according American Dental specification no.18 Results: The addition did not alter material, whereas significantly decreased its strength. Conclusions: incorporation into materials as antimicrobial agents had no negative strength, reduced material
