코멘트
- Segmental distalization was used to correct Class II over UL with Class II elastics
- Expansion of the upper arch was used to create an ideal arch form and create space for anterior retraction to correct the large overjet
- Expansion of the lower arch was used to alleviate crowding
- Additional aligners are used for bite settling and to further finish the overjet at 2 mm
