What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.

Summary

This study looks at whether standard, off-the-shelf jaw joint implants can be planned using 3D virtual software, just like expensive custom implants. Researchers will review X-rays from 30 patients who already had TMJ replacement surgery to see if virtual planning with standard implants could have achieved similar results. The goal is to make jaw joint replacement more affordable without sacrificing quality.

What this could mean

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

Active substance
Standardized temporomandibular joint prosthesis
What this could lead to
If successful, this could make TMJ replacement surgery more affordable and accessible by using standard prostheses with virtual planning.
What could go wrong
This is a small, retrospective study analyzing past cases, not a treatment trial. It may not prove that standard prostheses work as well as custom ones in all patients.
