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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 study tests custom-made 3D-printed metal plates for rebuilding the lower jaw after surgery, injury, or disease. Standard plates often need bending during surgery, which can lead to poor fit and breakage. The custom plates are designed from each patient's own CT scans to fit perfectly. Fourteen adults with jaw defects will receive the plate and be followed for 3 months to check for complications and jaw function.

What this could mean

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

Active substance
Patient-specific reconstruction plate (custom 3D-printed metal plate)
What this could lead to
If successful, this could make jaw reconstruction more precise and reduce the risk of plate failure or complications.
What could go wrong
This is a very small early study with only 14 participants, so results may not apply to everyone. The plate could still loosen, break, or cause infection.

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: 1. Patients with a segmental mandibular continuity defect, not involving the condyle. 2. Patients suffering from benign, locally invasive or malignant lesions that involving the lower border of the mandible. 3. Patients with recurrent lesions after resection. 4. Patients dealing with osteomyelitis or jaw osteonecrosis that is indicated for sequestrectomy. • Stage-III jaw osteonecrosis. 5. Patients with traumatic defects. 6. Patients with post-gunshot mandibular defects. Exclusion Criteria: 1. Medically compromised patients contradict the operation. 2. Patients with segmental mandibular defects that require condylar process resection 3. Patients with lateral segmental mandibular defects involving the condyle that require reconstruction using an alloplastic total joint. 4. Patients with an active infection at the site of resection.
