Archwire Progression:
The initial archwires were chosen keeping in mind the degree of malalignment and our goal of utilizing light forces. In the Upper arch, SPEED Supercable was chosen due to the severity of the malalignment. Supercable is able to impart rather low forces despite severe deflection. In the Lower arch, a low force .014 Nickel Titanium wire was chosen. Although it is arguable whether they are required, my choice was to use steel ligature ties selectively to eliminate any possibility of archwire release on severly malaligned teeth.
During tooth translation, a full sized Stainless Steel wire, with an electrolytically reduced posterior section, was utilized in the Upper arch. This wire inhibits anterior torque loss while permitting controlled posterior tooth translation.
Finishing in the upper arch was acheived with a slightly undersized Stainless Steel wire into which required detailing bends were easily and accurately placed. A full sized Stainless Steel wire was used in the lower arch, because no detailing bends were required.
