3D printed jaw brace could fix Children's bite without surgery

NCT ID NCT07710391

First seen Jul 17, 2026 · Last updated Jul 22, 2026 · Updated 2 times

Summary

This trial tests a new 3D printed dental appliance designed to correct an underdeveloped upper jaw in children aged 8-13 with class III malocclusion (where the lower jaw sticks out). The device, called a reverse twin block, is worn in the mouth to gently guide jaw growth over six months. Researchers will compare the 3D printed version to a conventional one to see if it improves jaw alignment, comfort, and oral health.

What this could mean

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

Active substance
a 3D printed reverse twin block appliance
What this could lead to
If effective, this 3D printed device could offer a more precise and comfortable way to correct jaw alignment in growing children, potentially reducing the need for more invasive surgery later.
What could go wrong
This is a small, early-stage trial with only 30 participants, so results may not apply to everyone. The device is new and its long-term benefits or risks compared to standard care are not yet proven.
