With the arch from improved, the length of mandibular dental arch is reduced. Pay attention to the root torque when the front teeth are retrated. When the maxillary arch is slightly extended,the teeth are aligned.At the same time with elastic class Ⅲ,produce a small amount of bite jump to anterior crossbite corrected.
