PURPOSE: The purpose of this meta-analysis was to evaluate the efficacy of the 2.0-mm locking miniplate/screw system in comparison with the 2.0-mm nonlocking miniplate/screw system in treatment of mandible fractures. METHODS: Articles published until March 2013 were searched in the PubMed and EMBASE electronic databases. Eligible studies were restricted to comparative controlled trials. RESULTS: Four studies with 220 patients and 420 fracture sites were enrolled into the analysis. The results showed that there were no significant differences in overall complications (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.24-1.36; P = 0.21), postoperative infection (OR, 0.43; 95% CI, 0.13-1.41, P = 0.17), and postoperative pain (P > 0.05) when comparing 2.0-mm locking miniplates with 2.0-mm nonlocking miniplates in treating mandible fractures. However, the use of 2.0-mm locking miniplates had a lower postoperative maxillomandibular fixation (MMF) rate than the use of 2.0-mm nonlocking miniplates (OR, 0.18; 95% CI, 0.08-0.41; P < 0.0001). CONCLUSIONS: Mandible fractures treated with 2.0-mm locking miniplates and nonlocking 2.0-mm miniplates present similar short-term complication rates, and the low postoperative maxillomandibular fixation rate of using 2.0-mm locking miniplates also indicates that the 2.0-mm locking miniplate has a promising application in treatment of mandibular fractures.
