Orthodontic-Surgical Correction of a Skeletal Class III Malocclusion: Case Report

Abstract

Introduction: Class III malocclusions and anterior crossbites are disturbing for patients because they are very apparent and often cause aesthetic and functional damage. Description: The clinical case describes a 19-year-old patient in good general health attended the dento-facial orthopedics service at the Rabat Hospital Center for Dental Consultation and Treatment presenting an anterior crossbite. The clinical examination and the cephalometric analysis showed that the patient had a Class III malocclusion of maxillary and mandibular origin with hyperdivergent facial type. An orthodontic-surgical treatment was well indicated for correction of the skeletal discrepancy in three phases: presurgical orthodontic preparation, orthognathic surgery and orthodontic finishing. Results: In reviewing the patient’s final records, the major goals set at the beginning of treatment were successfully achieved; the facial profile and proportion were significantly improved with solid functional occlusion Conclusion: In class III malocclusion when facial aesthetics is altered, the surgical-orthodontic treatment is the most indicated for patients who do not present facial growth.
