About

The invention relates to a composite material with improved antimicrobial properties, compared to the base material (glass ionomer cement) without negatively affecting the physical and mechanical properties, intended for use in dental applications, consisting of the solid phase - aluminofluorosilicate glass with particle size below 25 μm and a material with strong antimicrobial character, namely phosphate material as the hydroxyapatite type in which calcium is substituted with copper or zinc (in ratios Ca: substituted metal 1..5:0..4) previously decorated with phytosynthesized metal oxide nanoparticles using plant extracts from the Lamiaceae family.
