018X018 UPPER NITANIUM REVERSE CURVE SPEE STRAIGHT LEG (10)
Product code: [A226-276]
Straight Leg RCS: The anterior portion of the wire has a rocking horse curve and the legs of the wire are flat and level. Straight legs do not toe-in the molar, they help to tilt back molars for anchorage purposes. The wire easily puts curve of spee on the upper arch, and can be used to torque the molars bucally. Intrusion or extrusion of anterior teeth can also be accomplished. When flipped, it can be used to expand the lower arch. This is truly a multi-functional arch!
Reverse Curve of Spee (RCS) Archwires are best suited for:
Preventing molar tipping and rotations.
Maintaining anterior torque.
Initial leveling and aligning.
Arch consolidation and expansion.
Deep and open bite correction.
Retraction of flared, protruding incisors.
10 per pack.
