I've seen this time and time again, especially on this forum. Orthodontists will take off the braces too early. The bones tend to settle even after 1 year from surgery. The braces themselves, and even the titanium plates and screws they use to fixate the bones, are there to stabilize the bony structure. You can talk to any Oral Surgeon, and they will say that even with these plates and screws and braces, the bone is almost considered a fluid medium, meaning they are subject to movement, it's not a completely rigid structure, so the screws and plates will move within the bone.
Leaving the braces on for at least a year, can help at least, but taking them off at approximately 3-6 months is premature. I've recently seen a poster on this forum who had hers taken off after 6 months and she has a cant to occlusional plane, and it was severe to notice at resting lip posture.
So when the swelling initially goes down, your final facial structure won't be apparent, but years after. Also, are you having bone grafts for the CCW rotation? Or HA paste? I read the study by Wolford on using HA paste, and the first 3 months are critical, eating soft foods only, any undue stresses on the bone graft can cause instability of the structure around it, because of indifference of materials, unless it's your own bone or cadaver.
