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 Results may not be published yet.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 tested whether custom-made 3D-printed PEEK (a strong plastic) plates are as good as standard titanium plates for fixing a specific type of jaw fracture. Eighteen adults with a broken jaw angle received one of the two plates during surgery. Researchers measured bone healing on CT scans, bite strength, and wound recovery over 12 weeks.

What this could mean

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

Active substance
Custom-made 3D PEEK plate and 3D titanium plate (both are implantable devices used to fix broken jaw bones)
What this could lead to
If PEEK plates work as well as titanium, they could offer a lighter, more comfortable option for jaw fracture repair without metal interference in scans.
What could go wrong
This is a very small trial (18 people) comparing two surgical devices, so results may not apply to everyone. PEEK plates might not hold the bone as securely as titanium.
