abstract: This case report describes the treatment of a 12-year-old Chinese boy with a Class II skeletal profile, an extreme overjet, and a retrusive mandible. The patient was teased at school because of his appearance, and he was experiencing negative psychosocial impacts, including shyness and falling grades. Orthodontic treatment had a positive psychosocial impact on his life over a period of 10 years. The advantages of using functional appliances are highlighted in this report.
