A leucite glass-ceramic is prepared from a glass comprising: about 66.8 to about 71.9 mol % of SiO, about 8.5 to about 10.6 mol % of AlO, about 9.5 to about 12.8 mol % of KO, about 0.5 to about 4.0 mol % of CaO, about 0 to about 3.0 mol % of TiO, about 1.8 to about 4.0 mol % of NaO, about 0.1 to about 6.0 mol % of LiO, about 0 to about 1.0 mol % of MgO, about 0 to about 3.0 mol % of NbO, and about 0 to about 3.0 mol % of BO. The leucite glass-ceramic is prepared by subjecting the glass components to a nucleation heat treatment, followed by a growth heat treatment. The leucite glass-ceramic may be used in the fabrication of a Dental restoration using various processes, and may be used in the construction of Dental restorations such as ceramic Dental inlays, crowns, veneers, bridges, veneering materials for zirconium oxide restoration substrates, alumina oxide restoration substrates, or metal restoration substrates.

Leucite glass ceramics

A bioactive glass composition comprising one or more glasses comprising Si02, P205 and a fluoride, the Si02 content being less than 40 mole %, the P205 content being at least 4 mole %, and the fluoride content being greater than 1 mole %. The bioactive glass or glass-ceramic can be used in a number of medical applications, including dental applications such as toothpaste.
