Abstract

L'invention concerne un alliage dentaire résistant à la corrosion qui présente des caractéristiques de manipulation améliorées durant le plombage d'une cavité dentaire. Les particules d'alliage sont caractérisées en ce qu'elles ont une teneur en argent et en cuivre supérieure à la moyenne à la surface, une forme exceptionnelle différente de celle des alliages en paillettes ou sphériques et une surface spécifique de 0,23 à 0,26m**2/g environ. Application au plombage des cavités dentaires.
