Custom 3D-Printed retainers could outlast standard wires after braces

NCT ID NCT06529601

First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time

Summary

This study compares two types of fixed retainers used after braces to keep teeth aligned: a custom-made CAD/CAM retainer (Keeppy) and a standard braided wire retainer. Researchers want to see which one breaks or detaches less often over 6 months and 2 years, and which one keeps gums healthier. The trial involves 54 people aged 13 to 20 who have just finished orthodontic treatment.

What this could mean

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

Active substance
CAD/CAM mandibular fixed retainer (Keeppy)
What this could lead to
If successful, this could show that custom-made retainers are more durable and better for gum health than standard wire retainers, improving long-term orthodontic outcomes.
What could go wrong
This is a small, single-center trial with only 54 participants, so results may not apply to everyone. The custom retainer may not prove superior or could have unexpected issues.
