Contemporary resin-based composite materials for direct placement restorations: packables, flowables and others.

ABSTRACT

Resin-based composite (RBC) materials are composed of principal and diluent monomers, fillers, coupling agents and other components. These materials have been developed in recent years to produce packable and flowable materials, and materials which may release ions under specific conditions and which may contain fibres. Materials which are organic-inorganic copolymers have also become available. Long term clinical trial data are not available for the most recently introduced materials.
