This case report describes using a tooth scheduled for extraction as an anchorage aid during orthodontic treatment. Specifically, it details how an mandibular left first bicuspid tooth planned for removal was used to redirect undesirable side effects from uprighting a mesially tipped lower right second molar. By transferring mechanical forces to the tooth marked for extraction, the authors suggest treatment time could be reduced. The results demonstrated this "free anchorage system" successfully uprighted the mandibular molar as intended.

This e-poster presentation consists on a case report in which is described
the use of a tooth, whose extraction was indicated due to orthodontic
reasons, as an anchorage aid to receive undesirable side effects provided
by the orthodontic mechanics. This is called as Free Anchorage System. In
the case reported, the approach was designed to upright a counter lateral
molar tooth. The mandibular right second molar was mesial tipped due to
right first molar loss. Since the treatment plan involved extraction of
mandibular left first bicuspid, undesirable side effects associated to molar
uprighting movement, were transferred to this tooth. The results suggest
that treatment time can be reduced if undesirable orthodontic mechanical
side effects can be directed to a tooth whose extraction is indicated.
