Abstract

The aim of this case report presents a case of skeletal II and dental Class II treated with functional appliance in a male patient with increased openbite. A 9-year-old male patient was admitted to our clinic with gaping of anterior teeth. Clinical and radiographic evaluation revealed skeletal class II and dental class II anomaly and increased openbite due to mandibular retrognathia. 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, 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
