Comments

1. The efficiency of arch expansion in the mixed dentition is high.
2. Essentially complete control of permanent teeth with poorly developed roots and induction of unerupted teeth.
3.The roots of the teeth at 2.4 and 2.5 were growing normally before and after treatment and orthodontic treatment did not affect their growth and development (shown by contrast on radiographs)
