Damon Clear 2 combines the properties of low friction passive self-ligating technology with the aesthetics that image-conscious patients demand. The result is a crystal-clear appliance that goes beyond all aesthetic and functional expectations.Completely aesthetic passive self-ligation brackets, with unparalleled design. Polycrystalline alumina (PCA) material is resistant to staining from coffee, mustard, red wine and other agents. Eliminates the need for elastomerics, which stain and collect bacteria during treatment. Advanced passive self-ligation technology with low ligation force, minimizing frictional resistance for more efficient tooth movement.
