Alpha-Flow ® is a radiopaque, light cure resin-based micro-hybrid flowable composite. The specially formulated materials incorporate both a Nano-sized filler for increased flexibility and superior polishability and a 0.7-micron filler for excellent strength and wear resistance. This unique combination provides a material with extreme versatility for use in a wide range of procedures, including Class III and V cavity figurations and small Class I and II restorations. Alpha-Flow ® contains fluorescence to provide a duplication of the natural tooth surface.
