Summary

Background: Fractures of anterior mandible (symphysis and parasymphysis) make up about 9% to 57%, of mandibular fractures, and body fractures make up about 21%; posing challenges for stabilization due to anatomical constraints. Traditional 3D plates have limitations in this area, leading to the development of Modified 3D Rectangular Grid plates. Studies have shown that these plates offer superior stabilization over larger configurations while maintaining a low profile like miniplates. Additionally, design modifications ensure mental nerve preservation, balancing effective fixation with neurovascular safety.

Aim of this study: To evaluate the use of Modified 3D Rectangular Grid plates in comparison with conventional mini plates for fixation of mandibular fracture in the anterior and body regions, clinically regarding pain, interfragmentary mobility, maximal inter-incisal opening, wound healing, and sensory nerve evaluation, and radiographically regrading fracture reduction.

Conditions

  • Mandibular Fracture

Interventions

OTHER

Modified 3D Rectangular Grid plate

The system consists of a lower 1.5-mm rectangular plate and an upper linear plate that interlock through circular recesses and elevations. Each component is 0.75 mm thick at the junction, giving a total thickness of 1.5 mm. After screw fixation, it provides 3D stability similar to standard 3D plates while minimizing risk to the mental nerve.
