What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

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.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 13 people

The number the study aims to enrol. It can still change while the study runs.

Started

May 2024

Expected to finish

Oct 2025

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

6 to 9 years

Sex

Anyone

Healthy volunteers
