BIO-ACTIVE light Archwires


Bio-mechanical Properties Equivalent to INITIALLOY in a Small Diameter Archwire

BIO-ACTIVE™ Light lets you begin treatment with large diameter (.020” x .020” and, coming soon, .018” x .018”) archwires and activate third-order bends.

The biomechanical properties (force, superelasticity and shape memory) are equivalent to small diameter archwires such as INITIALLOY .014’’ (50 gf) on inscisors, INITIALLOY .018’’ (150 gf) on lateral section and INITIALLOY.020 ‘’ (250 gf) on molars.

Some archwires are available with a central V-Bend (or «dimple»). In that case, a letter D appears in the P/N. (please refer to the GC Orthodontics Products Catalog)
