In adult patient this type of case usually is treated with ？rst premolar extraction. This case report aimed to describe orthodontic treatment in maloclussion Angle class II division 2 to correct anterior crowding deep overbite which ？nally improve the aesthetics. A 19-year old female patient with overjet 0.5 mm, step bite (overbite 7.8mm) and ANB 10° (SNA 92°, SNB 82°).
