3D-Printed tooth spacer could replace metal in Kids' mouths
NCT ID NCT07161076
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests a new 3D-printed plastic device that holds space in a child's mouth after a baby tooth is lost early. It compares the 3D-printed spacer to the standard metal band and loop in 13 children aged 6-9. Each child gets both devices on opposite sides of the mouth, and the team checks success, comfort, and gum health over 12 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 3D-printed dental device (space maintainer)
- What this could lead to
- If it works, this could offer a more comfortable and effective way to keep space for permanent teeth after early baby tooth loss in children.
- What could go wrong
- This is a very small early study with only 13 children, so results may not apply to everyone. The 3D-printed device might break or cause gum problems more often than the metal one.
