What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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
Cancelled before anyone took part.

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

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tests a custom 3D-printed device to widen the upper jaw in 16 young adults aged 18-30. The expander is attached directly to the bone with mini-screws, avoiding pressure on teeth. Researchers will use 3D scans to measure how the jaw bones and teeth move over three months. The goal is to see if this bone-borne approach is effective for correcting a narrow upper jaw.

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 bone-borne rapid maxillary expander (device)
What this could lead to
If successful, this could offer a more precise and less painful way to widen the upper jaw in young adults, potentially reducing the need for tooth-based expanders.
What could go wrong
This is a very small early study with only 16 participants, so results may not apply to everyone. The device uses mini-screws, which carry risks of infection or loosening.
