Alignment of an ectopic canine with mini-implant anchorage: a case report.

Aims: To describe the treatment of an ectopic maxillary left canine and Class II molar relationship in a 12 year-old girl.

Methods: A pendulum appliance was used in a first phase of treatment to distalise the maxillary molars to a Class I molar relationship. In the second phase of treatment, a mini-implant, inserted between the roots of the left maxillary central and lateral incisors, provided anchorage to move an ectopic maxillary left canine into position.

Results: The implant remained stable throughout treatment and a maxillary canine - first premolar transposition was corrected. Good overjet and overbite were achieved and have been maintained one year after completion of active treatment.
