Bemerkungen
- Through the extraction of first premolars, we resolved the crowding in both upper and lower arches and corrected the upper and lower dental midline
- Distalization on the lower left molars to achieve Class II relationship
- In the additional aligners, sequential distalization was performed to improve Class II
- We continued using Class II elastics (3/16 inch, 4.5 or 6.5 OZ) in the additional aligners
- Precision bite lamp was effective in preventing the vertical bowing effect of the anterior teeth
- Vertical elastics were used on the left molar for detailing
