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 Results may not be published yet.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.

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 tested a custom 3D-printed guide and plate for repairing broken jaw bones (mandibular angle fractures) in 24 adults. The new method was compared to the standard technique using a single miniplate. The goal was to see if the custom device helps align the broken pieces more accurately and improves healing. Participants were followed for 6 months after surgery.

What this could mean

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

Active substance
custom 3D-printed surgical guide and titanium plate
What this could lead to
If successful, this could make jaw fracture surgery more precise and reduce complications like misaligned teeth.
What could go wrong
This is a small, early-stage trial with only 24 participants, so results may not apply to everyone. The custom device also requires extra planning and cost.

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 unilateral mandibular angle fracture with or without associated mandibular fractures in need of open reduction and internal fixation. 2. Patients above 18 years old 3. Sufficient dentition to reproduce the occlusal relationships 4. Patient's consent to participate Exclusion Criteria: 1. Patients with comminuted mandibular angle fracture(s) 2. Patients with any systemic disease that may affect normal healing 3. Patients undergoing chemotherapy or radiotherapy related to the head and neck region 4. Intra-bony lesions in the fracture area that may interfere with proper anatomical reduction.
