Preformed utility archwires with adjustable legs. Ideal for use in mixed dentition cases and available in three different metals: stainless steel, Nitanium® Super Elastic and Bio-Kinetix® Thermal NiTi. All archwires have a convenient 3mm step-down to fit all situations, allowing gentle force to be applied to anterior teeth. The Bio-Kinetix Utility Arch uses an anterior wire for lighter, continuous Nitanium force from the same wire diameter. More rapid tooth movement without root resorption. Pain relief in closed-bite T.M.J. cases. Frictionless alignment of upper and lower anteriors. Allows for use of auxiliary springs. Rapid midline corrections. Reduced bicuspid extractions and general treatment time.
