An interventional study of headless compression screw and conventional plates in Anterior Mandibular Fracture, sponsored by Cairo University. Not yet recruiting. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-17.
Sponsored by Cairo University · Not applicable, Interventional, and Other
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.

Exclusion Criteria:
Device: headless compression screw
Device: conventional plates
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.
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

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.
