Comparison of single locking miniplates versus double non-locking miniplates in fixation of anterior mandibular fracture

Abstract Background: Regaining normal occlusion, function, and bone alignment after mandibular fracture requires reduction and fixation, which can be achieved through either an open or closed approach. Various bone plating systems have been used to provide stable fixation of mandibular fractures. Purpose: The purpose of this study was to compare both clinically and radiographically, the use of single locking miniplate versus double non-locking miniplates in fixation of anterior mandibular fracture. Patients and methods: The main inclusion criteria in this prospective study were 20 patients with fractures in the main anterior mandibular region involving the symphysis and parasymphysis areas. Patients were randomly divided into two equal groups according to the type of plating system. Group I comprised of 10 patients whose fractures were fixed with a titanium single locking miniplate and group II comprised of 10 patients whose fractures were fixed with double conventional titanium miniplates. Results: At the different observation periods, no significant differences were observed between the two groups regarding soft tissue and bone healing, paresthesia, clinical stability, or intergonial distance. Conclusion: The use of a single locking miniplate fixation system in anterior mandibular fractures provided good stability, satisfactory bone healing, excellent occlusion, and early return to normal function, in addition to the intraoperative advantages of simplicity intraoperatively and reduced hardware.
