The Norris Extra Broad Archwires are 30% broader than the broadest arch on the market. This extra broad arch achieves a number of key efficiencies and effect (see below). Norris Extra Broad Archwires are the perfect complement in how they fully express the torque and tip of the bracket over existing passive systems, yet without the binding of other higher frictional systems.
Benefits & Features
Maximum Leveling & Alignment: Teeth are afforded a greater range of motion.
Treating Posterior Cross Bite: The broad shaped archwire can often be effective at correcting crossbites.
Produces A Beautiful Broad Smile: Reduces The Dark Posterior Buccal Corridors and expresses each tooth to its full outer- most potential.
Pre-Stopped: This helps control wire shifting archwire and can be tightened at any position along the arch in accordance with the doctor’s preference.
19×25 “Rounded Rectangular”: This “Rounded-Rectangular” NiTi, Beta and Stainless Steel archwire shape makes insertion, clip closure, and seating smoother than ever. Only the sharp corners are rounded so torque control is not compromised.
