Structure–Chemistry–Tribology Coupling and Artificial-Intelligence-Assisted Performance Prediction of Cubic Boron Nitride-Reinforced Heat-Polymerized PMMA Denture Base Composites
Heat-polymerized poly(methyl methacrylate) (PMMA) is widely used for denture bases but remains susceptible to surface deformation and sliding wear. This study evaluated the structure, chemistry, surface morphology, microhardness, and dry-sliding tribology of PMMA reinforced with 1, 3, and 5 wt.% cubic boron nitride (c-...
