BioActive is a shape memory archwire exerting progressive forces, 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 use shape memory at its best, cool the archwire before its insertion.
Some archwires are available with a central V-Bend (or «dimple»). And then, a letter D appears in the P/N.
