Purpose: Intermaxillary xation (IMF) is an essential principle in the management of mandibular fractures; but with the recent advent of open
reduction and internal xation (ORIF), the use of IMF is almost limited to intraoperative procedure only. This study aims to investigate and
compare the effectiveness of Erich arch bar & intermaxillary xation (IMF) screws for the management of mandibular fractures.
Materials And Method: A randomized prospective study was conducted on 20 patients with mandibular fracture, who were randomly allotted to
two groups. Group A patients received intermaxillary xation using Erich arch bar and group B patients received IMF screws. The parameters
assessed were time taken for application and removal of appliance, stability of occlusion, glove perforation, and pre-and post-operative plaque
accumulation.
Results: The mean time for placement of the Erich arch bar was 43.10 minutes as compared to 18.60 minutes with intermaxillary xation screws.
Better occlusal stability was shown with an arch bar over IMF screws, and was statistically signicant. More glove tears or penetrations occurred
during application in group A than Group B (p<0.01). Also, The Plaque Index assessment on removal of appliance showed a statistically signicant
difference between the two groups; higher in the arch bar group.
Conclusion: This study indicates that with acceptable occlusal stability, IMF screws technique is an effective and favourable alternative to Erich
arch bars for temporary intermaxillary xation in mandibular fractures.
