FIELD: medicine; stomatology. ^ SUBSTANCE: invention concerns self-hardening glass carbomer composition resulted from processing of fluorine-doped silica glass (a) poly (dialkylsiloxane) with chain-terminal hydroxyl group where alkyl groups contain 1-4 carbon atoms, (b) acid water solution and (c) release of processed fluorine-doped silica glass from acid water solution. Glass carbomer composition does not show any compression or expansions that is important property for packing of high durability and wear resistance. Composition is also characterised by lower scuffing and wear sensitivity, higher hardness, more smooth surface, higher color fastness, good matching, e.g., with bone tissue and lower water sensitivity. ^ EFFECT: composition has good hardness and reliability. ^ 11 cl, 3 tbl, 1 ex |
