Resolve C.II by sequential distalisation of both quadrants. The upper midline should be shifted 1 mm to the right, further distalisation of the 1st quadrant being necessary. If right C.II cannot be resolved by upper distalisation alone, make virtual jump of the lower arch.
The upper midline, once shifted to the right, shall be taken as a reference for centring the lower midline. This centring shall be done by means of a virtual jump of the lower arch.
To equalise the number of active aligners in both arches, coordinating the movements in such a way as to avoid overlaps between the premolars and molars of both arches.
Place buttons on upper canines and lower first molars.
Make necessary lower IPR (3 to 3) to resolve the Bolton discrepancy and end up with 1 mm of anterior protrusion.
Expand 1.5 mm in the 2nd and 3rd quadrant and 1 mm in the 1st and 4th quadrant, using coronovestibular inclination as far as possible, without exceeding 0º torque in the upper arch, and finishing with cuspid-fossa gearing in premolars and molars.
