Summary

This study compares two ways of positioning the jaw during corrective surgery for a misaligned bite (bimaxillary orthognathic surgery). The goal is to see which technique leads to healthier natural reshaping of the jaw joint (condylar remodeling) after surgery. Adults aged 18 to 65 with a specific jaw deformity will be randomly assigned to one of the two techniques. CT scans taken before, right after, and 6 months after surgery will measure changes in the joint's position and shape, along with clinical checks.

What this could mean

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

Active substance
Two surgical techniques for positioning the jaw during bimaxillary orthognathic surgery: one rotates the jaw segment, the other does not.
What this could lead to
If one technique proves better, it could guide surgeons to choose a method that reduces unwanted joint changes and improves long-term jaw function and comfort after surgery.
What could go wrong
This is a small, early-stage study, so results may not apply to all patients. The outcome depends on individual healing, and the study only follows patients for 6 months, which may not capture long-term effects.
