Metro Orthodontics Rectangular Super Elastic NiTi Archwires - Upper 0.018 x 0.025

NiTi (Nickel Titanium) archwires possess superelastic properties that deliver continuous, gentle forces well-tolerated by teeth during alignment. The material also exhibits shape memory, allowing it to maintain its predetermined shape throughout the treatment course, ensuring consistent force delivery.

The rectangular cross-sectional design of these archwires provides enhanced directional control and precision in tooth movement compared to round wires. This geometry allows for more specific force vectors, making it particularly effective for addressing complex orthodontic cases requiring controlled three-dimensional tooth positioning.

These archwires are used throughout orthodontic treatment phases including levelling, alignment, and finishing stages. The rectangular super-elastic design makes them versatile for addressing various malocclusion patterns and achieving specific treatment objectives across different case complexities.

Super-elastic NiTi archwires maintain relatively constant force levels over a wider range of deflection compared to stainless steel alternatives. This property reduces the frequency of wire adjustments and appointments, improving treatment efficiency while minimizing patient discomfort from force fluctuations.

These rectangular archwires are designed to fit standard rectangular slot brackets (0.022" × 0.028" or similar slot dimensions). Compatibility should be verified with your specific bracket system specifications to ensure proper engagement and force transmission during treatment.
