Comparative Evaluation of Efficacy of Conventional Erich Arch Bar Vs IMF Screws for Intermaxillary Fixation

Abstract

Aim : Evaluation of efficacy of Conventional Erich arch bar Vs Intermaxillary Fixation screws. Material and methods: This study we compared the efficacy of Conventional Erich arch bar and intermaxillary fixation screws with respect to plaque accumulation, time required for procedure, postoperative stability after achieving the intermaxillary fixation, mucosal growth and complications encountered for intermaxillary fixation. The participants were divided into two groups of 10 in each and designated as Group A and Group B. In Group A, Intermaxillary fixation was achieved by the conventional method using Erich arch bar, fastened with 26 gauge stainless steel wires. In Group B, Intermaxillary fixation was achieved by prefabricated intermaxillary fixation screws.Results: In present study total of 20 patients were analysed, The average working time for Group A and Group B were 96 minutes and 16 minutes respectively. Oral hygiene scores through modified Turskey Gilmore plaque index which was taken at immediate post operative, after 15 days, 30 days and 45 days. Maximum hygiene was maintained in intermaxillary fixation screws than conventional arch bar group but maximum stability was seen in the conventional arch bar group. In respect to mucosal coverage, mucosal growth was seen over intermaxillary fixation screws. Conclusion: This study emphasizes, the use of intermaxillary fixation screws is quick method than conventional arch bar. Conventional arch bar was significantly stable when compared with intermaxillary fixation screws therefore the patients who require long- term intermaxillary fixation, conventional arch bars would be a better option but it requires longer duration for the placement and had complications like needle sticks injury
