It is advantageous to scan patient for refinement prior to surgery, but wait to send for refinement afterwards and use photos from the buccal occlusion to set the occlusion.

Stabilization during surgery can be done with TADs placed:

Maxillary arch expansion should be completely corrected prior to jaw surgery.

Regular progress records to assess arch coordination are important during the pre-surgical phase.

Special attention needs to be paid to movements which may cause inferences and bite articulation issues during the time of surgery, especially during the initial treatment planning set-up. The movements which require overtreatment are:

There may be a period of lag for certain movements to express prior to surgery. Thus, it is recommended to go immediate into surgery after the patient finishes their last aligner.

The patient should try to get their aligners in as soon as possible post-surgery.

It may be most appropriate to level the Curve of Spee in a deep bite patient post-orthognathic surgery with aligners.

If performing a 3-piece maxillary surgery, an upper same day Essix is the only way to hold the upper arch post-surgery.
