[Traction of impacted teeth using bone anchorage and cantilever springs: a case report]

Egression and orthodontic traction can lead to parasitic movements on the anchoring elements. It is often necessary to use a device including several dental elements sometimes associated with traction auxiliaries. The author, through clinical cases, will develop his therapeutic approach, to limit these parasitic movements as much as possible. The use of a bone anchorage associated with a cantilever arch improves the management of this frequent orthodontic problem.
