CÉRAMIQUE POUR INCRUSTATIONS VESTIBULAIRES POUR DES RESTAURATIONS DENTAIRES EN DIOXYDE DE ZIRCONIUM STABILISÉ À L'YTTRIUM ET PROCÉDÉ DE FIXATION D'INCRUSTATIONS VESTIBULAIRES SUR DES RESTAURATIONS DENTAIRES EN DIOXYDE DE ZIRCONIUM STABILISÉ À L'YTTRIUM
The invention is directed to veneer ceramics for dental restorations of framework ceramics comprising yttrium-stabilized zirconium dioxide. It is the object of the invention to make possible a translucent veneer ceramic which has high flexural strength as well as excellent adhesion to the framework ceramic of yttrium-stabilized zirconium dioxide. According to the invention, this object is met in a veneer ceramic for dental restorations made of yttrium-stabilized zirconium dioxide which is produced from the following components: a) SiO2 58.0-74.0 percent by weight b) Al2O3 4.0-19.0 percent by weight c) Li2O 5.0-17.0 percent by weight d) Na2O 4.0-12.0 percent by weight e) ZrO2 0.5-6.0 percent by weight.
