Comments
Despite the fact that the roots of UR1 and UL1 were too short, we were able to minimize the damage by minimizing the amount of movement
To improve scissorsbite(UR4) and posterior crossbite(left side) we aligned and coordinated the arches, which proved to be very effective
In initial aligners, sequential distalization was performed to improve Class II
We continued using Class II elastics (3/16 inch, 4.5 OZ) in initial aligners
Optimized extrusion attachments for molars were effective for detailing on the left side molars
