Abstract
Abstract:

Objective: This study was aimed to evaluate the effect of incorporation of two-different nanoparticles; silica (SiO2), and zirconia (ZrO2) on flexural strength, impact strength, as well as, water sorption and solubility of thermoplastic resin material.
Materials and Methods: Two nanoparticles SiO2-NPs, and ZrO2-NPs (Nano-gate Company, Egypt) were incorporated into thermoplastic resin (Bre-flex, Bredenttm, Germany) with different concentration (1.5 and 7 wt.%). This study was divided into five main groups; unmodified “control group” and four modified groups according to the type and concentration of the incorporated nanoparticles.
Results: The results of this study revealed that; the incorporation of 1.5 wt.% SiO2-NPs significantly improve the flexural strength of thermoplastic resin. While, the incorporation of SiO2-NPs, and ZrO2-NPs nanoparticles insignificantly decrease its impact strength. However, they significantly increase water sorption and solubility of thermoplastic resin.
Conclusion: The incorporation of nanoparticles into thermoplastic resin at different concentrations could negatively affects its flexural strength, impact strength, as well as its water sorption and solubility.
