Patent

CA 2466620

The invention relates to an opalescent glass-ceramic product, especially an opalescent glass-ceramic product as a dental material or as an additive to or component of dental material, comprising at least the components SiO2, Al2O3, P2O5, Na2O, K2O, CaO and Me(IV)O2. In order to obtain improved opalescence with improved transparency, in addition to fluorescence, thermal expansion and a combustion temperature adapted to other materials, the opalescent ceramic product is devoid of ZrO2 and TiO2or is essentially devoid of ZrO2 and TiO2, such that the Me(II)O content in the glass ceramic is less than approximately 4 wt. % and the Me(IV)O2 content amounts to approximately 0.5 - 3 wt. %. The invention also relates to a method for the production of the opalescent glass- ceramic product. The glass-ceramic product can be used as dental material or as an additive to or a component of dental material.

L'invention concerne une vitrocéramique opalescente, en particulier une vitrocéramique opalescente utilisée comme matériau dentaire ou bien comme additif ou composant d'un matériau dentaire, laquelle comprend au moins les composants suivants: SiO¿2?, Al¿2?O¿3?, P¿2?O¿5?, Na¿2?O, K¿2?O, CaO et Me(IV)O¿2?. Pour que l'on obtienne une opalescente améliorée et également une transparence améliorée, ainsi qu'une température de combustion, une dilatation thermique et une fluorescence ajustées sur d'autres matériaux, il est prévu que la céramique opalescente soit exempte ou pratiquement exempte de ZrO¿2? et de TiO¿2?, que la vitrocéramique présente une teneur de Me(II)O inférieure à environ 4 % en poids et que la teneur en Me(IV)O¿2? soit d'environ 0,5-3 % en poids. L'invention concerne en outre un procédé de production d'une telle vitrocéramique. Cette vitrocéramique peut être utilisée comme matériau dentaire ou comme additif ou composant d'un matériau dentaire.
