Comparative Study between Titanium Miniplates and Three-dimensional C Plates for Fixation of Mandibular Fractures in the Mental Nerve Region: Randomised, Clinical Study

Abstract

Introduction: Mandibular fractures, representing 35.54%–44.2% of facial fractures, often affect the mandibular body and subcondylar region. Effective treatment seeks optimal reduction, stable fixation and functional restoration. This study assesses a modified three-dimensional C plate’s efficacy in treating mandibular fractures, emphasising occlusal forces and the mental nerve region. Materials and Methods: A randomised clinical trial (2019–2024) involving 20 patients with mandibular fractures was conducted. Group A (10 patients) received the modified C titanium plate and Group B (10 patients) received conventional miniplates. The clinical parameters – pain, occlusion, mobility, bite force and neurosensory deficits – were evaluated pre- and postoperatively at various intervals. Statistical analysis was performed using the SPSS software. Results: Group A shows superior bite force and functional outcomes, with significant neurosensory recovery by the 10th day. Both groups had no plate fractures, screw loosening or infections. Group A also had better stability, reduced procedural time and improved post-operative comfort. Conclusions: The modified C miniplate provides superior stabilisation, simplifies application, reduces complications and enhances early functional recovery compared to conventional miniplates.
