Designed to simplify Class II restorations. Rings are made with drawn-wire Nitinol (nickel-titanium alloy) as well as PEEK (polyether ether ketone), which produces superior spring characteristics reducing ring stretch. Less bulky, fully stackable design fits well in tight spots, handling MODs and multiple restorations with ease. Tip geometry reduces flash and ring pop-off. Bands are fully contoured for ideal anatomy, so they will not collapse on wider preps.
