Summary

This study tests a computer model that simulates how a person's face will look after orthognathic (jaw) surgery. Researchers will compare the simulation to actual 3D scans taken 6 months after surgery in 30 patients. The goal is to give patients a reliable preview of their post-surgery appearance.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could give patients a realistic preview of their face after jaw surgery, reducing anxiety and improving satisfaction.
What could go wrong
This is a small, early-stage study with only 30 participants, so results may not apply to everyone. The simulation might not perfectly match real outcomes.

This is an AI summary of the original study and may miss details. Read our disclaimer.
