Closed coil spring Ni-Ti SENTALLOY

Sentalloy Coil Springs: Superelasticity and Thermal Activation Sentalloy coil springs are NiTi orthodontic devices recognized as the first superelastic springs on the market. They are designed to move teeth with gentle, continuous force, minimizing periodontal stress. How they work: Activated by body heat (~37°C), triggering a martensitic transformation that maintains constant force regardless of activation degree. Clinical Benefits: Provides ideal physiological movement without patient compliance. Reduces chair time and the risk of root resorption. Availability: Open (expansion) and closed (retraction) versions in Light (100g), Medium (150g), and Heavy (200g) forces.
