The impaction of the maxillary permanent canines is relatively frequent clinical problem. This often leads to the resorption of permanent lateral and/or central incisor roots and causes space problems. Therefore, early detection, accurate diagnosis, and efficient treatment are essential.

The complex orthodontic mechanics applied to align the tooth back into the arch, may frequently lead to complications involving adjacent teeth and supporting tissues. Therefore, in order not to affect surrounding structures, simple mechanics with additional anchorage to create eruption path are preferred. Different clinical management options according to the position of the impacted canine and resultant space problems should be considered to solve the problem. Also, detailed planning of eruption guidance has a priority.

Here we report the cases of maxillary unilateral and bilateral canine impaction using lingual arches with auxiliary buccal wire arms to guide eruption without causing side effects on the adjacent teeth. For the accurate diagnosis, CBCT scanning helps locating the relative position of the impacted canine with the adjacent teeth. Also, close consultation with the experienced oral surgeons for surgical exposure of the impacted teeth may result in less soft tissue side effects. Finally, hygiene control around the once impacted tooth is essential in keeping the gingival tissues normal.
