Can a 3D-Printed retainer keep your gums healthier after braces?

NCT ID NCT07760935

First seen Aug 12, 2026 · Last updated Aug 14, 2026 · Updated 2 times

Summary

This trial compares two types of clear retainers worn after braces to see if the way they are made affects gum health. One retainer is created from a digital scan of the teeth, while the other uses a traditional plaster mold. About 52 people who recently finished braces will wear one type for six months, and dentists will measure plaque, gum swelling, and pocket depth at regular check-ups. The goal is to find out whether the digital method leads to healthier gums than the conventional approach.

What this could mean

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

Active substance
Digital vacuum-formed retainer (PETG, 1.5 mm) versus conventional vacuum-formed retainer (PETG, 1.5 mm)
What this could lead to
If digital retainers prove better for gum health, they could become the preferred choice after braces, reducing gum problems for many patients.
What could go wrong
This is a small, early-stage study (52 participants) and results may not apply to everyone. Differences in gum health could be minor or not clinically significant.
