We have effectually treated 22 years girl who had complained of an aterior open-bite. Treatment was based on non-extracted and multibanded technigue at the use of horizontal loop with 0.016 inch green Elgiloy wire. Anteior cross elastics, C1Ⅲ intermaxillary elastics, occasicnally C1.Ⅱ elastics were used. when vertical discrepancy was corrected, we changed the arch wire making use of 0.018 ×0.022 inch rectangular wire with 1st. and 2nd. order bend. After 12mons. the ideal arch wire with tie back loop was placed for stabilizing arch. Nearly after 20 months bands were removed and placed retainer.
