Abstract

La présente invention concerne un procédé permettant de fabriquer un matériau de restauration utilisé en dentisterie ainsi que le matériau de restauration dentaire réalisé selon le procédé de fabrication. L'invention concerne également une poudre de restauration des caries dentaires incorporant le matériau de restauration dentaire, une poudre de charge provisoire et une poudre adhésive temporaire, utilisable pour la restauration prothétique. Lorsque les matériaux de restauration dentaire selon l'invention sont utilisés séparément en tant que poudres pour l'émail, la dentine ou le cément en fonction du tissu respectif présentant les caries dentaires, les effets de la restauration peuvent être maximisés. Après la préparation d'une cavité pulpaire, l'obturation temporaire peut être réalisée avec l'adhésif temporaire efficace utilisable pour la restauration dentaire. En outre, la biocompatibilité de la restauration pour l'hygiène dentaire est excellente, puisque le matériau de substrat et les dents naturelles ont la même composition.
