These nickel-free, beta-titanium-alloy archwires are an excellent combination of the strength of stainless steel and the increasing resiliency of nickel titanium. They are bendable with high force and low deflection. An excellent alternative to TMA archwires, the CNA Beta III Archwires display superb formability for loop and bend placement, reducing important chairside time. Their flexibility makes them perfect for use during the mid-to-late stages of treatment. Nickel-free for sensitive patients. They provide twice the deflection of stainless without permanent deformation. Their smooth, high-polish finish provides less friction.
