Arch Wire

Orthodontic reverse curve wire made from nickel-titanium (NiTi) is designed to correct vertical discrepancies and arch leveling issues during orthodontic treatment. Its pre-formed reverse curve helps clinicians manage deep bite and open bite cases effectively while maintaining controlled and continuous force delivery.

Thanks to its superelastic behavior and rectangular profile, it provides improved torque expression, vertical control, and predictable tooth movement during early to mid-treatment stages.

Primary Clinical Applications

Deep Bite Correction

Orthodontic reverse curve wire intrudes anterior teeth and extrudes posterior teeth, which helps flatten the exaggerated curve of Spee. Consequently, it reduces excessive overbite in a controlled manner.

Open Bite Management

When clinicians invert the wire, it supports extrusion of anterior teeth and intrusion of posterior teeth. This approach assists in closing anterior open bites efficiently.

Arch Leveling

The reverse curve geometry helps level the occlusal plane, especially in lower arches where the curve of Spee appears more pronounced.

Torque and Vertical Control

The rectangular cross-section engages bracket slots more fully, allowing better torque expression and vertical tooth control compared to round wires.

Anchorage Assistance

The wire’s design redistributes forces across the arch, which can reduce the need for additional anchorage methods in selected cases.

Use with Elastics and Auxiliaries

Clinicians often pair it with Class II or Class III elastics, bite turbos, or other auxiliaries depending on the malocclusion.

Design & Material Features

Reverse Curve of Spee Geometry

The negative curve counteracts the natural curve of Spee, supporting vertical correction and occlusal leveling.

Nickel-Titanium Shape Memory

NiTi alloy restores the wire to its original shape after deflection, delivering light and continuous forces throughout treatment.

Rectangular Cross-Section

The rectangular profile allows three-dimensional control, including torque, rotation, and vertical movement.

Low Load-Deflection Rate

Gentle and consistent force application improves biological response and patient comfort.

Corrosion Resistance

NiTi material resists oral corrosion, ensuring durability over extended treatment periods.

Upper and Lower Arch Compatibility

Manufacturers design this wire for both maxillary and mandibular arches, depending on treatment goals.
