- The Norris System

Control Without Compromise. To achieve superior arch development and fully expressed smiles, research has shown low-forces and less friction are the obvious routes to take.  It is critical to preserve the free-sliding mechanics of passive self-ligation while reducing the learning curve.  

The Norris 20/26® PSL System incorporates best-in-class features including:

• .020 x .026 Archwire Slot

•  Reduced slot dimension to deliver unparalleled control while preserving free-sliding mechanics

•  Auto-Open/Auto-Close Door

•  The unique mechanism allows the door to actually “glide open” and “glide closed” once the door travels 50% in either direction.  

•  This “Assisted” opening and closing is the first and only of its kind, and is another leap forward in PSL technology.

•  Deep Tie-Wing undercuts

•  This true “Twin” design easily accepts ligature ties and chain for additional control.

•  Nickel-Free Chromium Cobalt

• Cobalt-Chromium boasts superior frictional characteristics vs. 17-4 Stainless Steel, while providing a safe solution for any potential nickel-allergy patients.
