The goal of this clinical trial is to learn how accurate patient-specific plates (PSPs) are for correcting a tilted upper jaw (maxillary cant) in people with facial asymmetry. The main questions it aims to answer are:
* How closely does the actual surgery match the virtual surgical plan? * How satisfied are participants with how they look after surgery?
Researchers will compare the surgery results using PSPs to the original 3D virtual plan to see how well they match.
Participants will:
* Have a CT scan and 3D virtual surgery planning * Get custom-made plates designed to fit their upper jaw * Undergo surgery to correct the tilt of the upper jaw * Be followed for up to 6 months to check healing and results
