POLYCARBOXYLIC ACID AND SILICA-ALUMINA (-CALCIA) CEMENT, KIT AND COMPOSITION THEREFROM

摘要

A poly(carboxylate) cement pack comprises as one component a water soluble poly(carboxylic acid) or a precursor thereof, and as another component an aluminosilicate glass, the ratio of acidic to basic oxides in the glass being selected such that the glass will react with a poly(carboxylic acid) in the presence of water to form a poly(carboxylate) cement. The aluminosilicate glasses of this invention are low in fluorine compared to known usable glasses. These glass containing cements find use in dental restorative practices.
