This article shows how to apply orthodontie force to impacted cuspids and bring them into proper arch position using a unique innovative anchorage system consisting of two short mini-screws placed buccally in cortical bone. Attached to this fixed anchorage is an .018 TMA round wire that emerges from the gingiva to exert direct 3D control on the canine without any additional dental support. The general procedure for moving impacted teeth into position and the mechanics utilized are described in detail with illustrations from clinical cases we have treated.
