ARCHWIRESARE NOT ALL CREATED EQUAL.COPPER NI-TI ® – NOTHING ELSE LIKE ITThe addition of copper in Ormco’s patented Copper Ni-Ti ® wire enhances the thermal-reactiveproperties of nickel-titanium to deliver optimal forces and unmatched tooth movementefficiency. Copper is just the beginning.4 Unloading (springback) properties facilitate fast, efficient toothmovement.4 A unique unloading profile provides continuous forces, even atvery small deflections (Fig. A).4 More resistant to permanent deformation than other nickeltitaniumwires.4 Batch-to-batch consistency, with a very precise temperaturerange, ensures true heat activation and consistent, predictableresults (Fig. B).4 Easy to engage, even in the most severe cases.4 A wide range of transformation temperatures are offered to treatany type of case.4 Copper Ni-Ti wires are available in a variety of arch forms:Damon TM , Orthos ® , Broad Arch and Tru-Arch ® .4 Damon TM Copper Ni-Ti archwires now feature preloaded stops foradded convenience and comfort.COMPARING LOADING/UNLOADING CURVES*TRANSFORMATION TEMPERATURE WITH STANDARD DEVIATIONS*Body temperature (37˚C)Room temperature (25˚C)Temperature ( ˚ C )Copper Ni-Ti 35˚c .017 x .025Neo Sentalloy .017 x .025* Data available on request.** Bioforce is a registered trademark of GAC Corp.

As the wire springsback, more-consistent forces are maintained,even in minor deflections.Fig. B – Most so-called heat-activated wires have wide manufacturingtolerances, forcing their transformations to be set near room temperature.Thus they are fully active well before insertion in the mouth. Theprecision of Copper Ni-Ti allows the wire to be easily engaged before fullactivation at body temperature, thus true heat activation.14
