IS THERE ENOUGH EVIDENCE TO REGULARLY APPLY BONE SCREWS FOR INTERMAXILLARY FIXATION IN MANDIBULAR FRACTURES?

The aim of this prospective study was to appraise the role of embrasure wiring in the treatment of mandibular fractures over the arch bar as adjunctive techniques of maxillomandibular fixation (MMF). This study was conducted on 40 patients who were surgically treated for mandibular fractures with accessory use of MMF (embrasure: group A vs. arch bars: group B). All patients were evaluated for demographic data, etiology, and location of fracture. Characteristically, the complications, including wire injury, infection, and malocclusion, were recorded. The data were analyzed using Student's t-test and chi-square test as appropriate. Statistical significance was set at p < 0.05). In this study, data from 40 patients were included. In group A (embrasure wiring), time required for placement of MMF was significantly less than (7.85 ± 0.81 minutes) that in group B, and also there was less incidence of wire prick to the operator in group A than in group B ( p < 0.05). However, in terms of wire prick and malocclusion, no statistically significant difference was noted in groups A and B ( p > 0.05). Patient treated with embrasure wiring intermaxillary fixation had better outcomes especially in terms of time of placement and less incidence of wire prick injury when compared with arch bar.

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 signicant. 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 signicant 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.
