N2 - The study aimed at developing a cytocompatible dental polymer composite with high mechanical and surface characteristics by reinforcing polymethyl methacrylate resin with graphene nanoplatelets and montmorillonite nanoclay. After ball milling the particles into the polymer samples were prepared via conventional compression molding method. Samples were tested for flexural strength, polishability, fatigue failure, wear, hardness, and cytotoxicity. The fracture mode and surface polish were tested using a field emission scanning electron microscope. Most properties displayed enhancement at the tested fraction weight in relation to the control, while some properties were downgraded. However, the tested polymer composite was cytocompatible at all concentrations. Within study limits, graphene nanoplatelets and montmorillonite nanoclay reinforced polymer brought about a positive effect to a particular degree. Establishing optimal concentration of reinforcement and alternate blending methods may boost the resultant characteristics of the resin composite.
