A state-of-the-art, nano-filled universal composite, ZNano from Danville Materials has a high percentage (73% by weight) of zirconia/silica-based filler (80 nm), creating superior esthetics, polish, and durability. ZNano also offers very high physical properties when compared to other composites. At a radiopacity of 205% of aluminum, it is easy to read. Shades are a close match to VITA.
