G4 Reverse Curve I Pre-Torqued NiTi Archwires

Pre-torqued Superelastic NiTi wires provide early and continuous translation of torque forces to anteriors. Effective on upper or lower arches, there is 20° of torque built into the anterior region of each wire. Torque forces can be applied labially or lingually by reversing the orientation of the wire. Three anterior mm sizes allow torque forces to be applied to anterior segment with choice of 3 wire sizes. To select proper mm size arch, measure along incisal edge from distal of lateral to distal of opposite lateral with a mm ruler. Measure in mouth or on model. The Lower arch is usually 28mm while the 34mm & 38mm is used on the Upper arch.
