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

- 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.
