    Abstract:
    PURPOSE: Intermaxillary fixation (IMF) is a fundamental principle in the management of mandibular fractures but with recent advent of open reduction and internal fixation (ORIF), use of IMF is almost limited intraoperatively. Therefore, we compared the efficacy of Erich arch bar versus embrasure wires for intraoperative IMF in mandibular fractures. METHOD: This prospective study was comprised of 50 patients with mandibular fractures who required ORIF with intraoperative IMF. Patients were categorized into two groups of 25 patients each: Erich arch bar technique was used for group A and embrasure wire technique for group B. Parameters were time taken for IMF, needle stick injury, occlusal stability, iatrogenic complications, and periodontal status of patients. STATISTICAL ANALYSIS: Chi-squared test and unpaired t test analyses was run on IBM SPSS 21.0 version (2015) software. RESULT: Mean time for placing embrasure wire (3.48 min) was significantly less than that for Erich arch bar (48.08 min). Needle stick injury rates to the operator as well as the assistants were significantly less when using the embrasure wire than the Erich arch bar. The Erich arch bar had significantly superior postoperative occlusion stability. Iatrogenic injury was more common when placing the Erich arch bar than the embrasure wire. Postoperative oral hygiene status was good in patients that received the embrasure wire. CONCLUSION: Embrasure wire technique is a quick, easy, and reliable technique for minimally or moderately displaced fractured mandible and had better clinical outcomes than did patients that underwent the Erich arch bar technique.
