Abstract
Pour la fabrication de produits dentaires, on utilise habituellement des matériaux produits selon la technique métallurgique. On ne peut à cet effet utiliser tous les matériaux. La transformation ultérieure des matériaux par coulée nécessite beaucoup d'énergie pour les faire fondre. L'invention concerne un procédé pour la fabrication de produits coulés dentaires et d'un matériau destiné à ces derniers. A cet effet, on fait fondre partiellement de fines particules du matériau et on compacte les particules fondues. On obtient alors un demi-produit fritté. Lors de la transformation ultérieure par technique de coulée, ce demi-fritté fond aisément dans le creuset d'une installation de coulée pour donner des produits coulés dentaires. Lors du traitement ultérieur mécanique, ce demi-produit fritté offre une bonne homogénéité. Les demi-produits frittés fabriqués selon ce procédé conviennent pour tous les produits techniques dentaires à fabriquer par technique de coulée, notamment pour des éléments constitutifs d'implant, des couronnes, des bridges et des modèles coulés.
