INTRODUCTION AND OBJECTIVE: Numerous methods have been described for achievement of Intermaxillary fixation in the treatment of fractures of facial skeleton. Conventional methods like Erich arch bars and eyelet wires are currently most common methods for achieving intermaxillary fixation (IMF), but they have their own disadvantages. Since 1989, IMF using intraoral self tapping IMF screws has been introduced for treatment of mandibular fractures. The aim of this work was to compare the efficacy, advantages, disadvantages indications and potential complications associated with Erich archbar v/s self tapping IMF screws in the management of mandibular fractures. METHODS: Twenty patients with mandibular fractures, reporting to Department of Oral and Maxillofacial Surgery, The Oxford Dental College, Bangalore were evaluated, to compare the efficacy of two techniques. The parameters considered were, time taken, perforations in the gloves, patient acceptance, oral hygiene, iatrogenic dental injuries, and needle stick injuries during IMF with Erich arch Bar and self tapping IMF screws. RESULTS: The mean time taken for IMF was 8.52 ± 2.7 min with screws as compared to 100 min with Erich arch bars. Mean number of perforations were significantly more in Group II. Oral hygiene status was good in 90% and fair in 10% of Group I and 100% fair in Group II patients. CONCLUSION: Use of self tapping IMF screws for intermaxillary fixation is a valid alternative to conventional Erich arch bars in the treatment of mandibular fractures. Iatrogenic injury to dental roots is the most important problem to this procedure, which can be minimized by careful radiographic evaluation and treatment planning.
