BIO-ACTIVE Archwires

BIO-ACTIVE is a shape memory archwire exerting progressive force from the midline to the posterior sectors.

Its forces are consistent with those found to be biologically necessary to move each individual tooth along the arch:

  • Arches .016"x.016" and .016"x.022" from 80g on incisors up to 240g on molars
  • Arches .018"x.018" to .021"x.028 from 80g on incisors up to 300g on molars

In order to best use shape memory, cool the archwire before its insertion.

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)
