It's very apparent there is a cant to the occlusional angle.
Did you surgeon not inform your Ortho to remain in braces during the post-op care? This is usually around 6 months.
I cannot find a reason as to why your Ortho did not know that the bones do tend to shift around after surgery, even with titanium plates and screws. This is negligence at the least.
You should try and speak to her as to why your care ended so soon. There is not going to be much for braces to fix this, you'd have to undergo another surgery to fix this. As soon as you alerted her there was some canting apparent, I do not believe she should have ignored your concerns.
There are however, other options you can explore. Find another Ortho and get a AAO transfer form (from your original Orthodontist), then work with another Oral surgeon or the same one.
If you feel as if you were misinformed of the complications afterwards, or not aware, and your Ortho ignored your issues, file a licensing board complaint.
