Treatment Plan • Straight wire series to level, align, rotate teeth • Open the bite with accentu-ated and reverse curves in 0.20 stainless steel arch wire • Constrict the maxillary arch • Develop the lower arch by unlocking the mandible • Cross bite elastics to correct the right buccal cross bite • Class 2 elastics to correct the molar and canine relation • Achieve maximum intercuspa-tion of the premolars • Place lower fixed 4-4 lingual retainer • Place upper Hawley retainer • Monitor third molars for removal • See periodically to adjust the upper retainer and check the band on the lower retainer • Estimated treatment time: 24 -30 months cating flared maxillary and mandibular incisors.
