The aim of the present study was to clinically and radiographically compare and evaluate the treatment outcomes using 3D miniplate versus conventional 2.0 mm miniplates in fractures fixation of the anterior mandible. The study enrolled 16 patients with a total of 18 fractures; suffering from anterior mandibular fractures (symphysis and/or parasymphysis) requiring open reduction and internal fixations through an intra-oral approach. Groups I patients were fixed using 3D titanium miniplates and screws. Group II patients were fixed using two 2.0 mm titanium miniplates and screws.
Postoperative primary clinical treatment outcome points for comparative evaluation for all patients were fracture stability, the need for additional IMF, the need for minor occlusal adjustments and satisfactory occlusion. Secondary assessment points were infection, wound dehiscence and neurosensory deficit. Radiographic evaluation postoperatively was in terms of reduction adequacy, bone union and condylar positional change measurement. With respect to all the evaluated parameters, statistical analysis showed no statistically significant difference between the two groups in terms
of clinical and radiographic treatment outcomes.
