Double-Efficacy archwires have a two parted cross-section. Precisely produced from a single piece of wire, the Double-Efficacy archwire offers a square or rectangular cross-section in the anterior part and a round cross-section in the posterior part. Thus in the front segment a perfect torque control of the incisors is possible, while in the posterior segment a minimized friction can be ensured. Effective and efficient sliding mechanics allow quick successes during space closure stage. Due to the use of high-quality materials the most different requirements regarding strength and rigidity can be fulfilled with Double-Efficacy archwires.
Square or rectangular Anterior Length: 34/38 mm for upper arch wire, 28 mm for lower arch wire.
The wires are available as Stainless Steel in all dental line arch forms.
