[Backshifting of lower canines in occlusion regulation]

In 17 patients the lower canines were shifted back during treatment of prognathic malocclusion and cross-bites. Stable devices with retraction loops, rubber or spring traction were used. The duration of active treatment was about 3 months, on average. During the treatment gaps after the removed premolars were closed completely, although this is nearly impossible when removable devices are applied.
