Background: Recently, various modifications in transorally placed miniplates for direct fixation of the mandibular fracture are gaining popularity. The modifications have various advantages like more rigidity, less foreign material, less time in application, etc. Among the various modifications of miniplates, three-dimensional (3-D) plating system is also gaining popularity. Thus, in the present study, we tried to evaluate the efficacy and postoperative complications of 3-D titanium miniplates in the treatment of mandibular fractures.

Materials and Methods: A prospective study was conducted on 40 patients with non-comminuted mandibular fractures. They were treated using a 2-mm 3-D titanium miniplate through intraoral approach. All patients were systematically monitored 6 months postoperatively. Outcome parameters like infection, hardware failure, wound dehiscence, sensory disturbance of the inferior alveolar nerve, occlusion, and 3-D plate stability were recorded. The statistical tests used in study were mean, standard deviation, and Chi-square test. P values less than 0.05 were considered significant and values less than 0.001 were considered very highly significant.

Results: Two patients had a postoperative infection with no consequences. All patients had normal sensory function 3 months after surgery. Plate fracture had not occurred in any patient. Occlusal was normal and wound dehiscence was not reported. 3-D plate was stable in all the patients.

Conclusions: It was seen that 3-D titanium miniplates were effective in the treatment of mandibular fractures and overall complication rates were lesser. In symphysis and parasymphysis regions, 3-D plating system uses lesser foreign material than the conventional miniplates using Champy’s principle.
