Nickel Titanium (NiTi) Superelastic 1

Along with low-friction Black-Ti® wire, Superelastic 1 (SE1) wire rounds out Ultimate’s austenitic Nickel Titanium wire line. The moderate, consistent forces exhibited by SE1 wire provide a great avenue for early to mid-stage treatment. It provides slightly less force than our Black-Ti wire, and is fully austenitic at room temperature. Due to its high flexibility and resiliency, Ultimate’s Superelastic 1 wire recovers beautifully from bends and deformation of angles up to 45°, and even up to 75° in some cases!
- Moderate, consistent force over a long activation period.
- Greater patient comfort than with Stainless Steel wires.
- Excellent resiliency.
- Highly flexible.
- Responsive to chilling.
- Af of 45-60° F (7.2-15.6°C).
- Square and Rectangle wires offer ability to simultaneously level and add torque and rotation earlier in treatment. More efficient than treatment with Stainless Steel.
| Arch Forms | NAT2, GLOBL, STD, OPTMA™, and INT. Superelastic Nickel Titanium wire is also available in 7 in. lengths and 15 in. spools. See Specialized Archwire section for Torqued, Connecticut Intrusion Arches (CTA®), and Utility Arches. |
