A significant part of the research and production activities is represented in field bioengineering by biomaterials used hard tissue restorations. They are great interest dental science, intending to improve technological aspects, monitoring their biological responses living organisms, but also redesign economic beginning with choice raw materials. In present work, light-curing composite were made from a polymer matrix consisting specific concentrations bisphenol A-glycidyl methacrylate base monomer (Bis-GMA), mixture two co-monomers, triethylene glycol dimethacrylate ethoxylated A-dimethacrylate (TEGDMA/BisEMA), alumina nanopowder (5 wt.% 10 wt.%). These materials mechanically tested for flexural strength compressive strength. The structural analysis these consisted SEM microscopy EDX elementary mapping. order extract 3D projections sample surfaces, produce indicative values roughness, micrographs processed open-source software. observe clear evolution mentioned properties, compared formed only Bis-GMA/TEGDMA/BisEMA composite, commercial resin, Filtek™ Supreme Ultra Universal Restorative, also. findings showed an increase mechanical properties manufactured concerning concentration nanoparticles aluminum. analyzes confirmed good homogeneity matrix. Mechanical nanocomposite reported 28.8 % higher than control biomaterial. comparison results resin encouraging.
