Orthodontic traction of a retained upper canine with Edgewise appliances: Case report

Resumen

Introduction: Diagnosis and treatment of retained teeth becomes necessary in order to avoid later complications jeopardizing the integrity of the dental arch. To this end a multidisciplinary work is instituted comprising from the early evaluation of the tooth until it is perfectly aligned in the arch, using the Orthodontics and Surgery services. According to each patient’s needs, orthodontic traction after surgical exposure may be the only treatment or it may be the first part of a more complex treatment. Objective: To apply traction to the upper right canine and to appropriately position it in the arch. Case report: Female patient, mesofacial, retained upper right canine, upper arch with a triangular shape and the lower one with a squared shape; severe crowding in both arches, the patient shows lateral upper incisors in crossbite, lower dental midline deviated to the left, molar class I on both sides and canine class not assessable on either side. Results: Successful traction of the upper right canine was achieved, taking the tooth to its proper position into the maxillary arch; molar and canine class I was achieved on both sides–arch shape was improved, appropriate overjet and overbite was achieved, and the profi le and the incisors’ long axis improved. Conclusion: Full fi xed appliances offer an option frequently used with traction applied to center of the alveolar process, using wire ligature from the buttons to the rigid archwire; this technique assures a good control system.
