Abstract:
A dental filler is disclosed. The filler is produced by admixing a metal oxide sol and a water-soluble organic binder; drying said mixed sol into a dried product; and calcining said dried product; wherein said filler is a substantially amorphous cluster. The filler can be mixed into a hardenable resin to provide radiopaque dental materials having desirable strength and aesthetic character.
