Introduction

Mandibular angle fractures account for approximately one-third of mandibular fractures and pose biomechanical challenges in surgical management. Although conventional miniplates are widely used, concerns regarding their strength in certain fracture patterns have led to evaluation of alternative fixation designs. This randomised clinical study compares single Y-shaped plate fixation with conventional miniplate fixation in mandibular angle fractures.

Methodology

Twenty patients were randomly allocated into two groups (2.0-mm Y-shaped plate or a 2.0-mm four-hole conventional miniplate with gap). Clinical and radiological outcomes were evaluated preoperatively and postoperatively using cone beam computed tomography. Parameters assessed included occlusion, maximum mouth opening, pain, neurosensory status, interfragmentary gap, and lower border distraction.

Results

Both fixation systems showed comparable outcomes in occlusion, mouth opening, and postoperative complications. The Y-plate group demonstrated higher bite force and more favourable radiological findings; however, these differences were not statistically significant.

Conclusion

Both systems were clinically effective for mandibular angle fractures. Although the Y-shaped plate showed trends towards improved functional and radiological outcomes, no significant superiority over conventional miniplates was observed. It may, however, offer better biomechanical stability in complex fractures or where customised fixation is required.
