Alp G, et al. - This study was performed to compare flexural strength of different computer-aided design/computer-aided manufacturing (CAD/CAM) poly(methyl methacrylate)-based (PMMA) polymers and conventional interim resin materials following thermocycling. The authors concluded that the flexural strength of CAD/CAM PMMA-based polymers was greater than the flexural strength of bis-acrylate composite resin. Compared to conventional PMMA resin, bis-acrylate composite resin had a greater flexural strength.
