Tunnel technique for the treatment of impacted mandibular canines.

The tunnel technique is a combined therapeutic approach that includes both surgical exposure of the impacted canine and orthodontic traction of the tooth to the center of the alveolar ridge, followed by final orthodontic alignment. A healthy periodontium at the completion of therapy is the expected outcome. The tunnel technique has been shown to be effective in the treatment of impacted maxillary canines and can be suggested for the treatment of infraosseous impacted canines in the mandible when the corresponding primary canine is still present. Through the description of clinical cases, the management of the tunnel technique is reported.
