Abstract

Introduction: Mandibular fracture is the most common type of trauma with various fixation modalities. One of these modalities is the use three-dimensional miniplates (3D) miniplate system.
Objectives: To compare the efficacy of rectangular grid miniplate with two standard miniplates in the management of mandibular angle fractures.
Materials and methods: Fourteen patients were randomly divided into two groups each including seven patients. Group A received Rectangular grid miniplate, and group B received two conventional miniplates. Clinical assessment visits are scheduled after 24 hours, one, four, six, and twelve weeks. A radiographic examination was done after twelve weeks to calculate the average bone density along line of fracture.
Result: After twelve weeks, both groups had normal occlusion, no wound infection or dehiscence, normal sensory function and a statistically significant reduction in pain intensity (p < 0.001). The average bone density improved statistically significantly in both groups A (p < 0.001) and B (p < 0.001) when comparing post-operative 12 week values to pre-operative values.
Conclusion: Rectangular grid miniplate in mandibular angle fractures fixation provides a predictable and stiff fixation option that can withstand functional loads and allow early return of patients normal life.
