Case report: Long-term outcome of class II division 1 malocclusion treated with rapid palatal expansion and cervical traction

A case of a Class II Division 1 malocclusion with reduced transpalatal width and unfavorable axial inclinations of the posterior teeth is reported. Rapid palatal expansion (RPE) was used for maxillary enhancement and molar distalization therapy to correct the anteroposterior dental discrepancy. This case report illustrates the results of the method of treatment used with a long-term (16-year-posttreatment) follow-up.
