Abstract
Background: A 53-year-old Thai female patient came to the orthodontic clinic with upper anterior teeth protrusion and insecurity while smiling as the chief complaints. Her expectation was to correct these problems. The examination showed severe skeletal Class II discrepancy with hyperdivergent facial pattern, orthognathic maxilla but retrognathic mandible, and anterior gummy smile. An orthodontic treatment combined with bimaxillary orthognathic surgery was planned. The treatment objectives were to correct the upper anterior teeth protrusion and gummy smile and improve the patient’s skeletal, dental, and soft tissue morphology. The treatment duration was 34 months to achieve normal skeletal, dental, and soft tissue structure in the anteroposterior, vertical, and transverse dimensions. At 30 months after completing treatment, the patient was recalled. We found acceptable function, improved esthetic results, and stability. The patient was pleased with the treatment outcome.
