Stepped-Force NiTi Archwires

Stepped-Force™ NiTi Archwire combines superelastic and thermal-activated technologies in a single wire for optimized orthodontic force delivery. The anterior segment features thermal activation, providing gentle therapeutic force for anterior teeth, while the posterior segment utilizes superelastic properties to deliver stronger force for posterior tooth movement. The bicuspid region serves as an intermediate transition zone. This innovative design creates a progressively increasing force gradient from anterior to posterior, matching the physiological requirements of different tooth structures. The result is ideal regional force levels that enhance patient comfort and reduce the need for frequent archwire changes.
