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 Results may not be published yet.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

Summary

This study looked at 20 people who needed their upper front teeth moved back after having their first premolars removed. They were split into two groups: one used a 5-mm power arm and the other a 9-mm power arm to apply force. Researchers used 3D X-rays to measure changes in bone thickness and tooth position, aiming to find which force level is safer and more effective.

What this could mean

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

What this could lead to
If successful, this could help orthodontists choose the best force level for safer, more predictable tooth movement.
What could go wrong
This is a small, completed study with only 20 participants, so results may not apply to everyone. It measures bone changes, not long-term outcomes.

This is an AI summary of the original study and may miss details. Read our disclaimer.
