First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at whether adding rubber bands (elastics) to standard clear plastic retainers helps keep an underbite correction stable after orthodontic treatment. Researchers want to see if this simple addition can reduce the need for future jaw surgery. The trial involves 42 people who have already completed treatment for a skeletal underbite.

What this could mean

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

Active substance

Class III elastics (rubber bands) added to clear plastic retainers

What this could lead to

If it works, this could offer a non-surgical way to maintain underbite correction and reduce the need for jaw surgery.

What could go wrong

This is a small, early-stage study with only 42 participants. The results may not apply to everyone, and the elastics may not prevent relapse or surgery.
