Manufactured from medical-grade nickel-titanium alloy, these arch wires demonstrate shape memory and thermal responsiveness, returning toward their preformed rectangular arch shape as intra-oral temperature increases. The combination of thermal activation and dimensional stability supports predictable force delivery over a broad activation range, allowing clinicians to advance treatment mechanics efficiently. Supplied in packs of 10 pieces, the wires are available in a range of rectangular sizes suited to standard bracket systems, providing dimensional versatility to match treatment phase requirements and bracket prescription.
