Abstract

Objective
Objective of this study was to investigate the effect on shear bond strength, hardness of the soft denture lining material reinforced by salinized silicon carbide Nanoparticles.
Material and methods
Silanized Silicon carbide NPs were added to the heat cured acrylic soft lining material. 60 specimens have been prepared according to the tests (surface hardness, shear bond strength), each group consisted of 30 specimens and these were subdivided into three groups: Control group, Reinforced heat cure acrylic soft liner (0.4% wt. SiC nanoparticles) group and Reinforce heat cure acrylic soft liner (0.6% wt. SiC nanoparticles) group. the strength of the shear bond, hardness of soft liner/ NPs composites was measured,
Result
The results showed a highly significant increase in Shear bond strength and hardness of soft lining material at 0.6% and 0.4% wt sci NP compared to control specimens.

Conclusion
the addition of silicon carbide nanoparticle into heat cure acrylic soft liner material improves mechanical properties such as surface hardness and shear bond strength.
