Summary
Three-dimensional (3D) plates provide superior occlusal stability for mandibular angle fractures compared to 2D plates. This leads to better functional restoration and fewer complications, making 3D plates a promising alternative for fracture management.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
- Biomaterials Engineering
Background:
- Mandibular fractures require effective management, with open reduction and internal fixation being the standard.
- Controversy persists regarding the optimal fixation methods for mandibular angle fractures.
Purpose of the Study:
- To compare treatment outcomes of three-dimensional (3D) plates versus two-dimensional (2D) plates for mandibular angle fractures.
- To evaluate the efficacy and complications associated with each plating system.
Main Methods:
- A clinical comparative study involving 30 patients with mandibular angle fractures.
- Random allocation into two groups: 3D plate fixation and 2D plate fixation.
- Assessment of surgical time, pre- and post-operative occlusion, mouth opening, and complications over 6 months.
Main Results:
- Both plating systems significantly improved mouth opening.
- No significant difference in surgical time or post-operative complications between groups.
- 3D plates showed a significantly smaller gap between bony segments at a specific point (P=0.04), indicating better stability.
Conclusions:
- Three-dimensional plates offer superior occlusal stability for mandibular angle fractures.
- 3D plates facilitate early functional restoration and may reduce the need for inter-maxillary fixation.
- 3D plates represent a viable alternative to conventional miniplates with potentially lower morbidity.
