In the treatment of maxillofacial fractures, Inter-maxillary fixation IMF is an important. The upper and lower arch bars or Ivy eyelet wiring is secured by wires and IMF is done with the help of box wiring. Typical indications for its use are minimally displaced fractures, deep bite cases, stabilization of fracture during open reduction and internal fixation, orthognathic surgeries and in tumor resection surgeries. Inter-maxillary fixation IMF is an important contrivance in the treatment of maxillofacial fractures, and is usually applied by wiring together the fixed upper and lower arch bars or Ivy eyelet [ 1 , 2 ]. Different IMF methods, including prefabricated arch bars, direct interdental wiring, continuous or multiple loop wiring, and IMF screws, have been reported [ 1 , 2 ].

Correspondence Address : Dr. Objective: Various techniques have been employed from time to time to achieve maxillomamdibular fixation. Although arch bars provide an effective and versatile means of maxillomandibular fixation, their use is not without shortcomings.
However the introduction of intermaxillary fixation screws IMF has eliminated many of these issues of arch bars. The aim of the present study was to compare the advantages and disadvantages of intermaxillary fixation screws over the Erich arch bars in mandibular fractures.
Materials and Methods: Sixty dentulous patients who reported to Department of Oral and Maxillofacial Surgery, Al-Ameen Dental College and Hospital, Bijapur with mandibular fractures and required intermaxillary fixation as a part of treatment plan followd by open reduction and internal fixation under GA were selected and randomly divided into 2 groups of 30 patients each that is Group A and Group B. Group A included patients who received intermaxillary fixation with Erich arch bars.
The parameters compared in both the groups included, surgical time taken, gloves perforation, post-operative occlusion, IMF stability, oral hygiene, patient acceptance and comfort and non-vitality characteristics. Results: The average surgical time taken and gloves perforations were more in Group A,the patient acceptance and oral hygiene was better in Group B, there was not much statistically significant difference in postoperative occlusion and IMF stability in both groups.
Accidental root perforation was the only limitation of IMF screws. Conclusion: Intermaxillary fixation with IMF screws is more efficacious compared to Erich arch bars in the treatment of mandibular fractures.
