Abstract
1. Glass frits required for producing an intermediary ceramic layer forming the dentine and/or the incisal, intended to cover the basal ceramic layer for opacifying the metal coping of a dental ceramo-metallic reconstruction, characterized in that they are obtained from a mixture containing at least two separate glass frits, namely : - approximately 80 % by weight of a first glass frit which is fusible and does not devitrify, and - approximately 20 % by weight of a second glass frit which is more refractory and devitrifies partially to leucite, the said mixture having a maximum particle size of less than 65 mu m and corresponding to the following overall composition : SiO2 59 to 59.5 % by weight Al2 O3 15 to 16 % by weight CaO 0.5 to 1.5 % by weight MgO 0 to 0.2 % by weight K2 O 11 to 13 % by weight Na2 O 7 to 8 % by weight B2 O3 2.5 to 3.5 % by weight BaO 0 to 3 % by weight CaF2 0.5 to 3 % by weight TiO2 0.2 to 0.5 % by weight CeO approximately 0.2 % by weight, the said mixture forming part of the composition of a ready-for-use paste containing an appropriate quantity of a plasticizing agent and capable of being packaged in a tub or a paste dispenser of the aerosol type.
