Abstract

Background: It is widely acknowledged that heat-cured soft denture lining materials sold commercially are far from ideal. As a result, the qualities of soft lining materials need to be improved.
- This study aimed to evaluate how various proportions of graphene nanoparticles affected the mechanical characteristics of soft denture lining materials, such as surface roughness and hardness.
- Materials and methods: In varying weight percentages (0.5% and 1% by weight), graphene nanoparticles were added to a soft denture lining material. Initially, a probe sonication device was used to distribute the silanized graphene nanoparticles into the soft-liner monomer. Then the soft-liner powder was added and mixed according to the manufacturer's instructions. 60 specimens were prepared and separated into three groups according to the test to be performed.FTIR investigation was performed to ascertain whether GNPs and the soft liner were undergoing any chemical reactions.
- Results: Using FTIR analysis, the current study showed that there was no chemical reaction between the soft lining material and GNPs. The mean hardness value significantly increased, while the surface roughness remained unaffected.
-Conclusion: The two surface roughness measurement techniques support one another because they produce different findings. AFM frequently conducts a more detailed surface investigation than a profilometer. The hardness of heat-cured acrylic-based soft denture liner material raised significantly with the addition of GNPs.
