Thepurposeofthisstudyisapplicationofthenovelnanostructurestoimprovetheperformanceofamalgam.Inthefirststageofthe research,grapheneoxidenanoplates(modifiedbyHummermethod)andmetallicoxide nanoparticles (zincoxide-copperoxide)synthesizedusingmetalsaltwereapplied.The synthesizedproductswereinvestigatedbyXRDandSEM analyses.Thecrystallitesizes of10,8.5and17.8nm wereobtainedforgrapheneoxide,zincoxideandcopperoxide, respectively. Inthesecondstage,nanoparticleswereaddedtotheamalgam capsule (dentalfiller) and combined withanamalgamator.Nanocompositeswereproduced each time by combining differentpercentages ofnanoparticles and mechanical properties including moldedhardnesswere measured by the microhardness gauge.As aconclusion, improvementofthemechanical properties including hardness according to thecomparisonofthestatisticsdone between the results and controlled amalgam wasacquired.
