摘要：

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.
