| Abstract: Objective: This study was aimed to evaluate the effect of incorporation of chitosan nanoparticles (Cs/NPs) on flexural strength, impact strength, fracture toughness as well as, water sorption and solubility of thermoplastic resin material. Materials and Methods: Cs/NPs (Nano-gate Company, Egypt) was incorporated into thermoplastic resin (Bre-flex, Bredenttm, Germany) with different concentration (1.5 wt., 5wt., and 7 wt.%). This study was divided into four main groups; unmodified “control group” and four modified groups according to the concentration of the incorporated Cs/NPs. Results: The results of this study revealed that; the incorporation of Cs/NPs decrease the flexural strength, impact strength, and fracture toughness of thermoplastic resin. While, the water sorption and solubility of modified thermoplastic resin were increased. Conclusion: The incorporation of Cs/NPs into thermoplastic resin at different concentrations could adversely affects its flexural strength, impact strength, fracture toughness as well as its water sorption and solubility.
