Definitions

  • Ceramic is a preferred material in prosthetics because of its biocompatibility.
  • Al 2 O 3 , ZrO 2 , Si 3 N 4 , MgO and SiAION ceramics are particularly suitable.
  • coloring ceramics By coloring ceramics, a denture can be produced whose color can be adapted to the color of the natural teeth. It is known to apply to ceramic body colored layers in a separate process or to impregnate a porous surface layer of the ceramic body with a liquid treatment of the material to be dyed and post-treated. This is a complicated process.

Abstract

Selon l'invention, pour fabriquer des corps frittés céramiques colorés, en particulier dans des applications en médecine dentaire, on connaît la technique qui consiste à appliquer dans une opération séparée des couches colorées sur les corps en céramique ou d'imprégner une couche poreuse de surface du corps en céramique d'une préparation liquide de la substance colorante et de réaliser un traitement de finition. Ce procédé est complexe. L'invention consiste donc à ajouter les substances colorantes à sec sous forme de poudre au matériau de la composition de base du corps céramique à former et à le mélanger de manière homogène à sec avec cette dernière.
