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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether custom-made PEEK (a high-performance plastic) plates are as good as or better than custom titanium plates for repairing fractures of the lower jaw. Twenty adults with a broken jawbone will receive one type of plate during surgery. Researchers will use 3D imaging software to measure how accurately the bones heal, comparing the two materials.

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 polyether ether ketone (PEEK) plates compared with custom-made titanium plates
What this could lead to
If PEEK plates prove more accurate or easier to use, they could become a preferred option for repairing jaw fractures.
What could go wrong
This is a small, early-stage trial with only 20 participants, so results may not apply broadly. PEEK plates may not outperform titanium in real-world use.

Study facts

What this study's own registry entry says, in plain language.

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 20 people

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

Started

Feb 2025

Expected to finish

Aug 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with at least a unilateral body fracture indicated for Open reduction internal fixation. --Dentate adult patients. * All ages and both sexes were included in this study. Exclusion Criteria: * Patients with systemic disease (may affect normal healing). * Patients with old and/or mal united fractures (affect accuracy of re-reduced the fractured segments). * Patients whom cannot tolerate follow up intervals (affect accuracy of study results).
