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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tested two ways of using 3D-printed models to help rebuild the lower jaw after tumor removal. Surgeons used bone from the patient's leg to reconstruct the jaw. One method used a full model of the healthy jaw, while the other used a segmented model that fit the leg bone pieces precisely. Both methods worked, but the segmented model gave more consistent facial symmetry. The study involved 36 people and showed that in-house 3D printing is a practical, low-cost tool for jaw reconstruction.

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

36 people

The number who actually took part.

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

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

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 undergoing segmental mandibular reconstruction with a free fibular flap. 2. Mandibular defects resulting from benign tumors, malignant tumors, trauma, or osteonecrosis requiring reconstruction. 3. Availability of preoperative high-resolution CT imaging suitable for virtual surgical planning and 3D modeling. 4. Agreed and signed the consent forms Exclusion Criteria: 1. Contraindications to free fibular flap harvest (e.g., significant peripheral vascular disease, prior fibular surgery). 2. History of previous mandibular reconstruction or major maxillofacial surgery altering baseline anatomy. 3. Preexisting severe facial asymmetry unrelated to the mandibular defect. 4. Inadequate imaging data or incomplete medical records. 5. Incomplete or poor-quality postoperative photographs preventing accurate asymmetry measurement.
