ßIII-CNA® Solid
Ultimate’s custom-developed, nickel-free ßIII-CNA® wire offers excellent formability and moderate forces for mid- to late stage treatment. Offering easier ligation than stainless steel and moderate tooth-moving forces, ßIII-CNA® wire allows for earlier use of rectangular wire for torque correction. Its formability is ideal for chairside placement of loops and bends for space closure, tipping, or focused tooth movement. Lengths are perfect for fabrication of auxiliary arches, retainer and palatal appliances, as well as devices requiring intricate bends or loops.
- Nickel-free! Eliminates nickel-sensitivity concerns.
- Formability allows for intricate loop designs.
- Gentler force than comparable size Stainless Steel wire. Provides for earlier use of rectangle wire to correct torque.
- Moderate stiffness for root correction.
- Overcorrection is possible by placing bends.
