Comments

We used Twin block to advance lower jaw when the girl were 10 years old. After 8 month twin block treatment, and the MA feature was launched in China, we started to treat this young girl with Invisalign Teen MA system. In order to correct deep bite, lower anterior teeth have been intruded, and lower premolars have been intruded.
