Abstract :The aim of this case report presents a case of skeletal II and dental Class II divisional I treated with functional appliance in a male patient with increased overjet. A 9-year-11-month-old male patient was admitted to our clinic with lower jaw retention. Clinical and radiographic evaluation revealed skeletal class II and dental class II division I anomaly and increased overjet due to mandibular retrognathie. The treatment was started with rapid maxillary expansion. After the retention period of 6 months, the treatment was continued with activator appliance to correct mandibular retrognathia. Mandibular advancement and class I molar and canine relationship were achieved after 10 months of activator use. In conclusion, in the case of dental class II division I, increased overjet, rapid maxillary expansion and functional treatment with activator appliance resulted in a good occlusion with normal overbite and overjet with dental class I relationships.
