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 This study
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 Results may not be published yet.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

Researchers at Al-Azhar University are studying how bite forces change after a procedure called piezocision-assisted rapid maxillary expansion. This procedure uses small surgical cuts to help widen a narrow upper jaw. The study compares teenagers and young adults to see if age affects the results. Sixteen patients with a narrow upper jaw will have their bite forces measured with a digital system before and after treatment.

What this could mean

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

Active substance
Piezocision-assisted rapid maxillary expansion, a procedure that uses small surgical cuts to help widen the upper jaw
What this could lead to
If the procedure changes bite forces in a predictable way, orthodontists could better plan treatment for a narrow upper jaw and set realistic expectations for different ages.
What could go wrong
This is a small study of 16 people with a short follow-up, so the results may not apply broadly. The procedure involves minor surgery and can cause pain, swelling, or infection.

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 16 people

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