Reverse Curve Wires are formed by special shaping to lower anteriors and open occlusion effectively. The corrective force depends on the curve degree and wire diameter.

ROUND ARCHWIRES
Reverse Curve Round Archwires have linear contact with brackets, which can bring vertical change of teeth position without changing the movement of molar area.

RECTANGULAR ARCHWIRES
The interface between wires and brackets could both lower anteriors and raise the molar area, straighten molars to improve the occlusion.
