Comparing Bone Healing in Jaw Fractures Fixed With Herbert Screws Versus 3D Miniplates (herbert screw)

September 12, 2026 updated by: Dina Abd El Aziz Metwally, Cairo University

"Comparative Assessment of Interfragmentary Bone Density in Anterior Mandibular Fracture Fixation Using Second Generation Herbert Screws Versus 3-Dimensional Miniplates: A Randomized Clinical Trial"

the goal of this clinical trial is to compare two methods of fixing fractures in the front part of the jaw (mandible): second-generation Herbert screws and 3-dimensional miniplates.

Importance:

Choosing the right fixation method is crucial for proper bone healing after a jaw fracture.

Participants:

Patients with recent anterior mandibular fractures requiring surgery.

Key Findings:

The study assessed which method better maintained bone density around the fracture, indicating potential benefits for healing.

Implications:

Understanding the effectiveness of these methods aids healthcare providers in making informed decisions, ultimately improving patient outcomes.

Design Details

  • Primary Purpose: Other
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: interventional group
•The second-generation Herbert screw has emerged as a minimally invasive alternative, offering compression across fracture lines and requiring less surgical exposure.
Active Comparator: comparator group
•Conventional fixation using 3D miniplates has been widely accepted for managing anterior mandibular fractures because of their ability to provide stable three-dimensional support
