Interdisciplinary treatment of Class III malocclusion: a case report.

The case report describes the multidisciplinary treatment of a 25-year-old male patient with a Class III malocclusion. Anterior and bilateral posterior crossbites were present. To correct the posterior crossbite a surgically assisted rapid maxillary expansion was performed. The significant three dimensional skeletal discrepancy was solved in a second phase with a surgical advancement of the maxilla. Functional and aesthetic occlusion in an improved facial profile was achieved with an interdisciplinary treatment that included orthodontic treatment, maxillofacial and periodontal surgery, and direct composite restorations.
