Title (EN) AESTHETIC DENTAL MATERIALS
(FR) MATERIAU DENTAIRE ESTHETIQUE
Abstract: front page image
(EN)The invention provides for a material comprising (a) a hardenable resin; and (b) fillers comprising (i) clusters of nano-sized particles, the clusters comprising non-heavy metal oxide particles and heavy metal oxides and being not fully densified; and (ii) non-agglomerated, non-heavy metal oxide nano-sized particle or non-agglomerated, heavy metal oxide nano-sized particle. The material is suitable for use as dental materials.
(FR)La présente invention concerne un matériau comprenant (a) une résine durcissable et (b) un matériau de remplissage. Ce dernier comprend, d'une part (i) des nanoparticules en grappes, et d'autre part (ii) des particules non agglomérées. Les nanoparticules en grappes (i), qui comprennent des particules d'oxydes métalliques non lourds et des particules d'oxydes métalliques lourds, ne sont pas totalement densifiées. Les particules non agglomérées (ii) sont essentiellement des nanoparticules d'oxydes métalliques non lourds et des nanoparticules d'oxydes métalliques lourds. Ce matériau convient comme matériau dentaire.
