Abstract:
A case of a Class II, division 1 malocclusion with reduced transpalatal width is reported. The only treatment provided for this patient was rapid palatal expansion. After expansion, the mandible seemed to be carried forward to its normal position, resulting in a spontaneous correction of the Class II malocclusion. This case report illustrates the outcome of the method of treatment used with a long-term (14-year posttreatment) follow-up.
