Ectopic Canines; Prevention, Exposure and Extrusion for a Great Natural Smile
After 3rd molars, the second most commonly impacted teeth are the maxillary canines. The impaction of a canine not only poses an aesthetic concern but may also present significant risk for maxillary lateral root resorption if not treated by age 12. Prevention of impaction can be achieved via appropriate diagnosis and intervention during growth and development. Radiographic and clinical evaluation during the mixed dentition to prevent impactions will be discussed. These interventions such as extraction of primary teeth and orthodontic therapy to open space for the permanent canine will be reviewed. Cases where this intervention is not provided in a timely manner or does not have a successful preventive outcome will also be presented. Radiographic techniques to identify the location of the ectopic canine will be reviewed. Clinical cases involving surgical management techniques for exposure and subsequent orthodontic management for extrusion into the arch will be presented. In addition, two cases of adult canine and exposure and long term follow up will be presented.
