Summary

This study looked back at 420 patients who had jaw surgery after using either clear aligners or traditional metal braces. The goal was to see if the type of orthodontic preparation affected how smoothly the surgery went. Researchers checked things like how stable the jaw was during surgery and if any extra adjustments were needed. The findings could help patients and surgeons choose the best approach for planning jaw surgery.

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 clear aligners work as well as braces for preparing teeth before jaw surgery, patients may have a more comfortable and less visible orthodontic experience.
What could go wrong
This is a retrospective study, not a controlled trial, so results may be influenced by patient selection. It only looks at short-term surgical outcomes, not long-term success.
