Objective
To systematically review the efficacy of poly-L-lactide (PLLA) material treatment versus titanium plates treatment for mandibular fractures.
Methods
We searched the Cochrane Library, PubMed, Embase, Chinese Journal Full-text Database, VIP Database, and Wanfang Database to collect literatures about randomized or non-randomized controlled trials using PLLA treatment (the trial group) versus titanium plates treatment (the control group) for mandibular fractures in the last ten years (from January 2007 to March 2017). The quality evaluation and data extraction were carried out by 2 reviewers independently and analyzed by Review Manager 5.3 software.
Results
A total of 8 literatures including 453 patients with mandibular fractures were included in this Meta-analysis. There was no significant difference in total complications between the two groups [odds ratio (OR)=0.98, 95% confidence interval (CI) (0.55, 1.75), P=0.95], including dislocation healing [OR= 0.96, 95%CI (0.46, 2.01), P=0.90], occlusal disturbance [OR=1.53, 95%CI (0.61, 3.87), P=0.37], infection [OR=0.63, 95%CI (0.23, 1.74), P=0.37], and secondary operation [OR=0.46, 95%CI (0.17, 1.27), P=0.14].
Conclusion
There is no significant difference between PLLA and titanium plate in the treatment of mandibular fractures.
