This wire is terminated distal to the first molar, or even the second bicuspid attachments, because of its relative vulnerability to functional stresses in the molar region. Engagement of brackets on severely rotated teeth is simply a matter of manipulating Supercable™ fully into place with a ligature director and then closing the Spring Clips to trap it. Regardless of the malalignment, Supercable™ archwires are easily and fully engaged with no plastic deformation of any component. Its extremely low unloading force plateau assures that appliance-induced stresses within the periodontium will remain at near optimal levels throughout. The threshold forces exerted by this light wire, initially increase cellular activity thus preparing the surrounding tissue for impending changes. Continued use of such light forces eliminates excessive tissue compression thus allowing optimal tooth movement. 21 ROUND RECTANGULAR or SQUARE SPEED WIRE™ SPEED’s edgewise slot will accommodate virtually any size or configuration of archwire except those with an extremely large labio-lingual dimension (e.g. .018 x .025 in an .018 slot or .022 x .028 in an .022 slot). RECOMMENDED ARCHWIRE PROGRESSION The proper selection and progression of archwires is most important in ensuring excellence in treatment efficiency and results. SPEED Appliance design greatly simplifies and enhances archwire selection and effectiveness. SPEED’s wide interbracket span, predictably light frictional drag, and full control, with even the most undersized archwires, maximize efficiencies of tooth movement while ensuring excellence in finishing. Although SPEED’s edgewise slot will accommodate virtually any size or configuration of archwire, experienced SPEED users have found that the selected archwires outlined below most fully exploit SPEED’s unique benefits. These are recommended for best results.
