Introduction: Repairing of fractured heat cured denture base is a clinically significant measure, either as a temporary or permanent treatment. Many attempts were conducted to increase the strength of the repaired material by reinforcing with various composite fillers. Objective: The aim of this study was the use of nano-aluminum silicate fillers for improving some properties of cold cure acrylic resin that is used in repairing fracture heat cure denture base material. Material and methods: Total 4 groups of specimens were prepared for testing the surface roughness and the surface hardness. The 1st group of specimens was constructed from heat cured acrylic, 2nd group of specimens was constructed from cold cured acrylic only, while the 3rd and the 4th group were constructed from cold cure acrylic reinforced with 3% and 5% nano-aluminum silicate composite fillers. The mode of failure was examined with the aid of a light microscope. Statistical analysis of data was performed using SPSS version 24. Results: In the results, the addition of filler to cold cure acrylic resin increases the transverse strength mean value and these value increases as the concentration of fillers compared with unreinforced cold cure groups. Regarding the impact strength, there is a significant decrease in the mean value of the reinforced groups. Meanwhile, there was a statistically none significance among the tested group for surface roughness, hardness and impact strength. Conclusion: Addition of salinated aluminum silicate nanofillers (3%, 5%) to cold cured acrylic resin improves the transverse strength of material without changing other properties when tested as a repair material for heat cure acrylic resin.
