Dentsply SDR Flowable Bulk Filling Material is a one-component, fluoride-containing, visible light cured, radiopaque resin composite restorative material designed to be used as a base in Class I and II restorations. SDR material has handling characteristics typical of a "flowable" composite but can be placed in 4mm increments with minimal polymerization stress.
SDR material has a self-leveling feature that allows intimate adaptation to the prepared cavity walls. Available in one universal shade, it is designed to be overlaid with a methacrylate-based universal or posterior composite for replacing missing occlusal or facial enamel.
