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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests two types of plates used to fix a specific kind of jaw fracture, called a subcondylar fracture. One plate is made of titanium, the standard metal. The other is made of PEEK, a medical plastic that can be 3D-printed. Researchers will compare how well each plate restores jaw function by measuring how wide patients can open their mouths after surgery. They will also check imaging results to see if PEEK causes fewer problems on scans than titanium.

What this could mean

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

Active substance
PEEK trapezoidal plates versus titanium trapezoidal plates for surgical fixation of subcondylar fractures
What this could lead to
If PEEK plates work as well as titanium, they could offer a safer option for jaw fracture repair with less imaging interference and fewer implant-related complications.
What could go wrong
This is a small early study with only 24 patients, so results may not apply broadly. PEEK plates might not hold the bone as securely as titanium, and surgery carries standard risks like infection or implant failure.
