Abstract
La présente invention divulgue un bloc de masse dentaire pour la coupe, le bloc de masse dentaire étant un bloc de vitrocéramique comprenant une phase cristalline dans une matrice de verre amorphe, la phase cristalline principale étant du disilicate de lithium, et de l'eucryptite étant en outre inclus en tant que phase cristalline supplémentaire. Le bloc de masse dentaire est un matériau à gradient fonctionnel qui présente un gradient de la taille de la phase cristalline principale par rapport à la profondeur, et dans lequel aucune interface n'est présente à des points au niveau desquels la valeur de gradient de la taille de cristal principale change. Le bloc de masse dentaire est utile pour fabriquer une prothèse dentaire artificielle qui est similaire à une dent naturelle, la phase cristalline supplémentaire d'eucryptite facilite le traitement mécanique du bloc de masse dentaire par rapport au cas où seul le disilicate de lithium est présent, et le bloc de masse dentaire réduit non seulement le temps nécessaire à la fabrication de la prothèse dentaire artificielle, mais peut également procurer l'effet d'une stabilité structurelle accrue en termes de distribution de forces en raison de la fonctionnalisation par gradient des propriétés mécaniques.
