Abstract

Background:  Intermaxillary fixation is regarded as a significant step in the management of maxillofacial trauma since it restores the pre-injury occlusion. Various types of tooth-borne devices like arch bars are used to achieve intermaxillary fixation. To overcome the shortcomings of Erich arch bar, cortical bone screws for IMF were introduced. The present study was designed to compare the efficacy of IMF screw over Erich arch bar in mandibular fracture. Material and Method: The prospective randomized study was carried out on 60 patients. Patients were randomly divided into 2 groups of 30 patients each. In group A, intermaxillary fixation was achieved by using Erich arch. In group B, IMF was achieved by the use of IMF screws. In this study, patients were evaluated for the following variables- surgical time for achieving IMF in both technique, oral Hygiene, Intraoperative and postoperative complications.  Result: The average surgical time taken for achieving MMF per patient in group A and group B was 85.32 min and 16.75 min respectively. Plaque deposition was more in Erich arch bar group.  Conclusion:  IMF screw offers an effective alternative for Erich arch bar in the treatment of the minimally displaced mandibular fracture.
