ClinConnect Summary

This clinical trial is studying a new way to predict how a patient's face will look after undergoing a specific type of jaw surgery known as bimaxillary orthognathic surgery. This procedure is often performed on individuals with Class III dentofacial deformities, where the jaw alignment can affect both appearance and function. The researchers are using advanced 3D imaging technology to improve the accuracy of these predictions, which could help doctors plan surgeries more effectively and achieve better outcomes for their patients.

To participate in the study, individuals must have had certain types of jaw surgery and provide preoperative and at least six months postoperative 3D scans of their face. However, those with specific conditions, such as previous facial surgeries, certain craniofacial anomalies, or significant facial asymmetry, will not be included. The study uses existing imaging data, so no new procedures will be performed for this trial, and participants' privacy will be protected throughout the process. The findings from this research aim to enhance our understanding of facial changes after surgery and improve the overall treatment planning in maxillofacial surgery.
