Abstract

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