Study summary

This study compares two methods for fixing fractures of the front part of the lower jaw:

Conventional plates and screws Headless compression screws

Patients are randomly assigned to one of the two treatment groups. Researchers will use imaging to see whether either method causes a significant change in the position of the mandibular condyles, which are the parts of the jaw that connect to the jaw joints.

Why it matters: Proper condylar position is important for normal jaw movement, chewing, and overall TMJ function.

Main goal: To determine whether conventional plates or headless compression screws provide better preservation of condylar position after surgery.

The study may help surgeons choose the most appropriate fixation technique for patients with anterior mandibular fractures.

Interventions

  • Deviceheadless compression screw

    Headless compression screws provide interfragmentary compression along the long axis of the mandible while maintaining a low-profile fixation system. Their design allows stable fixation with minimal hardware bulk and may reduce unwanted transverse displacement of fracture segments.

  • Deviceconventional plates

    Conventional plate-and-screw fixation has long been considered the standard treatment modality for anterior mandibular fractures. However, plate fixation may induce transverse mandibular widening or narrowing due to plate adaptation forces, screw placement, and limited interfragmentary compression

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Sep 2026; primary completion for Feb 2027, 5 months later.

Of 38 non-industry interventional studies with no phase under Mandibular Fractures, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 24. This study's planned 5 months is below that.

Counting every sponsor, half of 38 studies reached it within 13 months; a quarter within 9 and three quarters within 24.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
