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 Results may not be published yet.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.

This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a custom 3D-printed surgical guide helps dentists place tiny screws in the upper jaw more accurately than the traditional free-hand method. Each participant gets both techniques on opposite sides of their mouth, so the comparison is direct. The goal is to see if digital planning leads to better screw position, stability, and fewer complications during orthodontic treatment.

What this could mean

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

Active substance
CAD/CAM 3D-printed surgical guide
What this could lead to
If digital guides prove more accurate, this could make orthodontic miniscrew placement safer and more predictable, reducing complications and improving treatment success.
What could go wrong
This is a small, early-stage study with only 33 participants. The benefits of the guide may not be large enough to justify the extra cost and planning time, and results may not apply to all patients.
