Lingual orthodontic treatment and absolute anchorage to correct an impacted maxillary canine in an adult.

There are 2 major drawbacks to the classic orthodontic-surgical approach for resolution of impacted teeth in adults: appearance and duration of treatment. This case report illustrates the lingual orthodontic treatment of an adult with an impacted maxillary canine; absolute anchorage was achieved with a miniscrew placed in the palate. The combination of invisible appliances and a nondental anchorage system is particularly useful in adults and should make treatment available to more patients.
