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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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 whether acid-etched titanium miniscrews stay more stable than standard machined ones when used to anchor orthodontic treatment. About 30 people with crowded or misaligned teeth will receive both types of screws in different parts of their mouth. The goal is to see which surface helps the screws hold better, potentially improving the success of braces or aligners.

What this could mean

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

Active substance
titanium miniscrews with machined or acid-etched surfaces
What this could lead to
If acid-etched miniscrews prove more stable, they could improve orthodontic treatment outcomes by reducing screw failure.
What could go wrong
This is a small, early-stage study with only 30 participants, so results may not apply broadly. Both screw types carry risks like loosening or infection.
