“…Majority of the studies included in the analysis recommend the use of IMF screws for MMF. A systematic review conducted by Bins et al 37 suggested that IMF screws can be used for temporary MMF for uncomminuted fractures. Considering the result of present meta-analysis, high risk of bias, confounding factors and the considerable heterogeneity we confirm that there not enough evidence to conclude that IMF screws are alternative to Erich arch bars.…”

Study Design: Systematic review and meta-analysis. Objective: Maxillomandibular fixation (MMF) is a step of paramount importance during the management of maxillofacial trauma. Erich arch bars are being used for this purpose for decades but with advances in maxillofacial trauma management, intermaxillary fixation screws came into existence and are being used routinely. The present study was designed to identify if the intermaxillary fixation screws are really an alternative to Erich arch bars for management of maxillofacial trauma. Methodology: An exhaustive literature search was conducted in May 2020 on various electronic databases and studies comparing Erich arch bars and intermaxillary fixation screws were recruited for the analysis. Random-effects model with Mantel Haenszel statistics was used to analyze oral hygiene and duration of achieving MMF. Results: A total of 96 studies were identified, out of which 8 studies were included in the meta-analysis. There was no statistically significant difference in oral hygiene status of the patients in both the groups. Intermaxillary fixations screws required statistically significantly less time in achieving MMF. Needle stick injury was prominently seen with the use of Erich arch bar whereas other complications like mucosal coverage, root injury, screw loosening and screw fracture makes the use of intermaxillary fixation screws questionable. Conclusion: The present meta-analysis suggests that there is not enough evidence to recommend the use of intermaxillary fixation screws as an alternative to Erich arch bars. Further research with large sample size, high quality evidence and better methodology is recommended in this direction.
