The aim of this case report; is to present the treatment of a male patient with skeletal Class II, dental Class II division II associated with deep bite by the using of functional appliance through a short period of fixed orthodontic treatment. A 14-year 4-month old male patient applied for treatment in our clinic with a cheef complains of retrognathic mandible. The radiographic and clinical examinations and evaluations showed skeletal class II anomalies. Dental class II division II anomaly with increased over bite had been identified. The orthodontic treatment started with functional appliance as activator. After 8 months mandibular advanced and Class I molar and canine relationship had been achieved. after functional treatment 0.018 slot straight wire Roth brackets applied for both the upper and the lower teeth. After 6 months for both jaws a 0.016 x 0.022 stainless steel wire had been applied. After that the intrusion of the incisive teeth had been achieved by using CIA. In order to achieve a Class I molar and canine relationship, Class II elastics had been used at the end of the treatment. A case with a skeletal class II and Dental class II division II with increased over bite was treated through a 2 years and 8 month of treatment and dental class I relationship with normal overbite and overjet and good occlusion achieved at the end of the treatment.
