Abstract

Présentation de nanoparticules d'oxydes métalliques et d'oxydes métalliques-silice dont les surfaces forment un complexe avec une base polymérisable, biocompatible et hétérocyclique. Les compositions polymérisables sont préparées en chargeant ces nanoparticules dans des matrices monomères à base d'acrylate, dont les compositions peuvent alors être photopolymérisées pour donner des solides opaques aux rayons X, transparents ou translucides. Les méthodes de formation de ces nanoparticules liées en complexes et de ces compositions, ainsi que les utilisations de ces mêmes compositions à des fins médicales et de restauration dentaire sont également décrites.
