Composite material for dental restoration with increased compression strength and antimicrobial properties and method of producing it

The present invention refers to a composite material with improved mechanical properties and antimicrobial effect, intended for use in dental applications, consisting of aluminofluorosilicate glass with a particle size below 45 μm, the liquid component of the glass ionomer cement and an antimicrobial component with a role in improving the properties mechanical, consisting of apatite material (of the hydroxyapatite type - Ca10(PO4)6(OH)2 in which the calcium:magnesium ratio is 10:0..1:1) decorated with silver nanoparticles having a crystallite size below 15 nm, phytosynthesized using extracts of plants from the Lamiaceae family, such as hyssop (Hyssopus officinalis L.), white horehound (Marrubium vulgare L.), oregano (Origanum vulgare L.) or white dead nettle (Lamium album L.) and eugenol in concentration 7..14% (alcoholic solution), the procedure for obtaining the composite material consisting of five stages, obtaining the apatite material (in which calcium may or may not be partially substituted with magnesium) by the sol-gel method, the phytosynthesis of silver nanoparticles, the decoration the apatite material with metallic nanoparticles and the phenolic compound (eugenol) followed by mixing with the aluminofluorosilicate glass until complete homogenization, and in the fifth stage the liquid component of the glass ionomer cement is added_._
