Beschreibung
Zusammenfassung:	A polymerizable, radiopaque dental composition including: one or more ethylenically unsaturated, polymerizable monomer and/or polymer, possible conventional fillers, pigments, initiators, activators, and thixotropic auxiliary material, as well as, in addition, a heavy-metal fluoride with very low solubility selected from the group consisting of complex heavy-metal fluorides having the general formula MIIMIVF6, where MII is a calcium, strontium, or barium ion, and MIV is a titanium, zirconium, or hafniun ion. These filler compositions exhibit excellent X-ray visibility along with excellent optical properties.
