Assessment of the Accuracy of Patient Specific Plates for Correction of Maxillary Cant in Facial Asymmetry
Assessment of the Accuracy of Patient Specific Plates for Correction of Maxillary Cant in Facial Asymmetry: A Prospective Clinical Trial
Cairo University
8 participants
Jan 1, 2025
INTERVENTIONAL
Conditions
Summary
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

Interventions
Patients will undergo orthognathic surgery using Virtual Surgical Planning (VSP) combined with custom-fabricated Patient-Specific Plates (PSPs). High-resolution CT scans will be used to create 3D models of each patient's craniofacial structure. Surgical plans will be developed using specialized CAD software, and PSPs will be designed and manufactured using 3D printing and milling techniques. During surgery, these custom plates and accompanying cutting guides will be used to accurately reposition the maxilla, ensuring precise correction of maxillary cant. This approach aims to improve surgical accuracy, reduce operating time, and enhance postoperative outcomes.
