Palatally impacted canines: the double traction technique.

When closed eruption is used to recover palatally impacted canines, patients risk a second surgical operation because the traction attachment could come off or the wire ligature, which is connected to the attachment, could break. In order to reduce this risk, a new simple technique has been developed. Instead of the classic single one, two attachments are bonded to the impacted canine. During the orthodontic finishing, the technique includes a mandibular premolar bracket bonded to the ectopic canine. This device should produce a more negative torque (Torque -17 degrees rather than -7 degrees) over the root, which usually remains in palatal position soon after the performed crown recovery.
