Management of Mandibular Fractures Using Locking and Nonlocking Miniplates

Purpose: The study proposed to determine the superiority between locking plate and nonlocking miniplate for mandibular fractures (MFs) treatment. Methods: A comprehensive electronic search examining Medline-Ovid, Embase, and PubMed databases language without date was performed in February 2018. Inclusion criteria were studies in humans, including randomized controlled trials, controlled clinical trials, with the aim of comparing the 2 techniques. The quality of studies was assessed, and the relative risk (RR) with its corresponding 95% confidence interval (CI) was assessed to measure the effect size. Results: Thirteen publications were enrolled into the analysis. The results showed that there were significant differences in overall complications (RR, 0.62; 95% CI, 0.351–1.094; P = 0.06), postoperative infection (RR, 0.503, 95% CI, 0.223–1.136) when comparing locking miniplates with nonlocking miniplates in treating mandible fractures. The incidence of malocclusion showed a statistically significant difference in the outcome favoring locking miniplates (fixed: RR, 0.503; 95% CI, 0.125–2.030; P = 0.06). In addition, the use of locking miniplates had a lower postoperative maxillomandibular fixation rate than the use of nonlocking miniplates (RR, 0.414; 95% CI, 0.196–0.872; P = 0.002). Conclusion: The result of meta-analysis revealed that use of locking plate is superior to the nonlocking plate in the reducing of postoperative complication rates in the management of MFs.
