An 11 years old girl reported with the chief complaint of poor appearance of her front teeth. There was anterior open bite with constricted palate and bilateral posterior cross bite. Lips were full, averted with normal length and there was more gingival exposure on smiling. OPG confirmed mixed dentition; 1st permanent molars were erupted whereas 2nd and 3rd molar were un-erupted. Cephalo-metric analysis showed SNA to be 820 and SNB 760. The ANB value was 60 and over Jet 7mm indicating moderate class-II skeletal pattern. Wits analysis confirmed this observation with an AO-BO distance of 3mm and the lower incisor – APO =- 1. Interincisal angle was 1240. Space analysis revealed a requirement of 3mm in lower and 5mm in upper arch. The aims of the treatment were to correct the anteroposterior and transverse discrepancies, leveling and aligning of arches, correction of over jet, overbite, and elimination of the habit. Non-extraction modality of the treatment was adopted upper and lower edgewise appliances with rapid palatal expander, and for distalization headgear was prescribed.
