评论

1. Mandibular advance with the Precision Wings are very useful for deep bite improvement.
2. This treatment is a combination of expansion, proclination and intrusion of lower dentition
3. In the Additional Aligner phase class II elastics are used to maintain jaw relation and to help close posterior open bite.
