One of the most challenging issues we as orthodontic practitioners face is post-treatment relapse. When we move a lingually placed lateral incisor, central, or palatally impacted cuspid, the key is to get the roots lined up under the crowns so relapse is minimized. The excellent torquing spring (ETS) was born out of my own frustration at watching anterior teeth relapse on occasion.
It will fit on .017 x .025 through .019 x .035 stainless or TMA wire. It doesn’t work as well on nitinol, as the edges of nitinol wire are more rounded.
Once the spring is in position, crimp the last two or three winds on the spring’s coil with a 142 plier and place in the mouth. Then sit back and watch it work.
