Retraction of canines with control of tooth inclination is described, using the direct application of extra-oral traction. the technique requires a modified facebow to be inserted into buccal tubes on canine bands; no archwires or springs are involved. In the upper arch the facebow is connected to a standard variable pull headgear, while a supported cervical strap is required for the lower canines. Preliminary investigations are outlined and the procedure is illustrated by some clinical cases from a pilot feasibility study.
