Temporary tongue thrust: failure during orthodontic treatment.
This report presents the case of a 25-year-old male patient who sought orthodontic treatment. Oral examination revealed an Angle Class I relation, with a bimaxillary dento-alveolar protrusion, evidence of anterior crowding, and a large overbite and overjet. Radiographic examination revealed a skeletal Class I occlusion. During the distal movement of the canines, occlusal interferences between the canines occurred and the commencement of a tongue thrust was observed. After correction of the applied forces, the canine movement was completed and the habit was no longer detectable. The incident indicates that an unusual oral habit suspiciously occurring during treatment should lead to an immediate reconsideration of the orthodontic treatment strategy.
