Hybrid Denture Acrylic Composites with Nanozirconia and Electrospun Polystyrene Fibers

Summary

Denture base resin is PMMA, and it breaks. This study reinforces it on two fronts at once: nano-zirconia particles for hardness and electrospun polystyrene fibres for toughness, the fibres bridging cracks that the rigid ceramic filler cannot. Surface modification of both reinforcements governs how well they bond to the matrix, and the combination is tuned to adjust the physical and mechanical properties of the hybrid composite - a dental materials problem addressed with a fibrous reinforcement rather than a stiffer filler.
