Surgical Management of Vertical Class III Malocclusion with Severe Skeletal Openbite Using Minimum Pre-surgical Orthodontics - A Case Report.

Rationale And Patient Concerns: A 19-year-old male patient presented with a dentoalveolar Class III malocclusion on a Class III skeletal base with facial asymmetry, increased facial proportions, complicated by anterior open bite of 6.2 mm, unilateral posterior crossbite with Index of Orthognathic Functional Treatment Need score of 5.4.

Introduction: An anterior open bite is a form of vertical discrepancy that presents as a lack of contact between maxillary and mandibular segments. The treatment modalities usually involve either intrusion of posterior teeth or extrusion of anterior or a combination of both. The anatomical relationship between the apex of the maxillary molar roots to the inferior wall of the maxillary sinus floor is crucial in planning posterior intrusion.
