Abstract

L'invention concerne un procédé pour former un mélange de plusieurs porcelaines afin d'obtenir un mélange de porcelaines ayant des caractéristiques de couleurs prédéterminées correspondant à celles d'un échantillon de référence. Ce procédé est caractérisé en ce qu'il comprend les étapes qui consistent: 1 degrés A mesurer les valeurs des densités optiques pour le rouge, le bleu et le vert de cet échantillon de référence; 2 degrés A choisir une première porcelaine ayant des valeurs de densité optique pour le rouge, le bleu et le vert proches de celles de l'échantillon de référence; 3 degrés A déterminer les valeurs des densités optiques respectives dont les moyennes avec les valeurs des densités optiques pour le rouge, le bleu et le vert de la première porcelaine sont égales aux valeurs respectives mesurées des densités optiques pour le rouge, le bleu et le vert de l'échantillon de référence; 4 degrés A choisir une seconde porcelaine ayant des valeurs de densité optique pour le rouge, le bleu et le vert proches de celles déterminées à l'étape 3; et 5 degrés A mélanger des quantités appropriées de ces première et seconde porcelaines. Application à la fabrication de dents artificielles.
