Bemerkungen

We expanded both arch. For upper arch, we used Class II elastic to increase anchorage of distalization. For lower arch, we added a little IPR to level Spee's curve. We used optimized rotation attachments to derotate lower premolars. Aligners were changed every 10 days. No addintional aligners were used for this case.
