Spiral wires are placed in mandible and then the free end of both maxillary and mandibular wires are tightened to achieve IMF. The average surgical time taken and gloves perforations were more in Group Tecbniques 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.
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.
Direct bonding of arch bars in the management of maxillomandibular injuries. Open in a separate window.
A rapid, safe, and non-invasive maxillo-mandibular fixation technology. Discussion A good IMF technique should be easy and quick, low cost, secure desired occlusion, avoidance of unwanted forces on anterior teeth, minimally invasive, safe for the patient, possess an emergency quick release system.
Transalveolar screws and the incidence of dental damage: Once all six wires are passed, then the upper and lower wire ends are twisted together to achieve IMF Fig.

Then the wire is wound around the tip of intermxaillary instrument four of five times. This leads to formation of a spiral through which the other end of the wire is taken out to lock the spiral Fig. Erich arch bars, intermaxillary fixation screws, mandibular fractures.

None Sources of Funding: Some authors have used single wires for IMF with bucco-lingual stabilization [ 12 ]. Different IMF methods, including prefabricated arch bars, direct interdental wiring, continuous or multiple loop wiring, and IMF screws, have been reported [ 12 ]. The aim of the present study was to compare the advantages and disadvantages of intermaxillary fixation screws over the Erich fixatiob bars in mandibular fractures.
Foxation for correspondence and reprint requests Yuvika Raj Kumar, B. No specialized instrument or laboratory work is required. Intermaxillary fixation with IMF screws is more efficacious compared to Erich arch bars in the treatment of mandibular fractures. Steinbacher Plastic and Reconstructive Surgery. A good IMF technique should be easy and quick, low cost, secure desired occlusion, avoidance of unwanted forces on anterior teeth, minimally invasive, safe for the patient, possess an emergency quick release system.
This technique makes use of six evenly spaced spiraled wires three in each maxilla and mandible.
Spiral Intermaxillary Fixation
As less number of wires is ifxation in this technique, hence the incidence of needle stick injury and gingival trauma also decreases as compared with arch bars.
The Ulster hook for intermaxillary fixation. Typical indications for its use are conservative management of minimally displaced fractures, maxillofacial fractures in deep bite cases, stabilization of fracture during open reduction and internal fixation, orthognathic surgeries and in tumor resection surgeries.
However, the authors have found that there fixahion certain drawbacks pertaining to this technique, for example, if one set of upper and lower wires breaks while twisting, then all the wires need to be released and redone.
Yuvika Raj KumarB. Fixatoon disadvantage of this technique is that removal of the wires after completion of procedure is intermaxllary difficult, as we cannot hold the wires for retrieval. After achieving the occlusion, the ends of wire are twisted together on the buccal surface of the lower premolar and molar teeth on both sides Fig. Author information Article notes Copyright and License information Disclaimer.
