The central incisor tip in both Mn/Mx is not good, and there is space.

Make an ideal arch line by adjusting rotation and tip, and retraction, and finally setup to resolve space.

Since the amount of overjet is larger than the normal occlusal, we adjusted the - torque.

The axis of the maxillary central incisor is - tipping, so the axis is corrected by + tipping and the space is uniformed.

Using the remaining space, the mandibular was aligned through tip adjustment and slight torque adjustment.

Since it is a case where the maxillary overbite is insufficient, a little intrusion was added when retraction.

We setup without IPR because there is enough space.

Since this patient has a poor periodontal disease, we divided the steps as finely as

possible to reduce the amount of movement per device.

After alignment by applying rotation, we perform retraction over three layers, and slowly close space.
