Intermaxillary fixation screws in position Click here to view. Sitemap What’s New Feedback Disclaimer. A new and easy technique for maxillomandibular fixation. Although arch bars provide techniqued effective and versatile means of maxillomandibular fixation, their use is not without shortcomings.

An audit of mandibular fractures treated by intermaxillary fixation using intraoral cortical bone screws.

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.

The number of wires and size of spiral can be varied depending on the type of fracture and embrasure space, respectively. It firmly maintains the desired occlusion. Here we present a new IMF technique using single loop-designed wires, providing bucco-lingual stabilization. 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.


The Ulster hook for intermaxillary fixation. Loop of the wire can be held for easy and swift removal of wires.

Spiral Intermaxillary Fixation

Since time immemorial there is a constant quest of oral and maxillofacial surgeons to find a quick way for IMF. 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.

The loop wire is passed around the neck of the upper first molar tooth, both ends of loop wire going from buccal to palatal, one along the mesial surface and other end along the distal surface of tooth Fig. Plast Reconstr Surg ; It lends support to the fractured fragment from both buccal and lingual surfaces. 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.

The disadvantage of this technique is that removal of the wires after completion of procedure is very difficult, as we cannot hold the wires for retrieval. In this technique, single 26 gauge stainless steel wire of 6 inches is taken, which is shaped as Ivy loop. Br J Oral Maxillofac Surg.

A New Simplified Technique for Intermaxillary Fixation by Loop-Designed Wire

Br J Oral Maxillofac Surg ; Some authors have used single wires for IMF with bucco-lingual stabilization [ 12 ]. However the introduction of intermaxillary fixation screws IMF has eliminated many of these issues of arch bars.


Holmes S, Hutchison I.

Author information Article notes Copyright and License information Disclaimer. Once all six wires are passed, then the upper and lower wire ends are twisted together to achieve IMF Fig.

Spiral Intermaxillary Fixation

This article has been fication by. 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. Same procedure is repeated on the premolar teeth and on the contralateral side molar and premolar regions. Erich arch bars, intermaxillary fixation screws, mandibular fractures. Results of intraoral cortical bone screw fixation technique for mandibular fractures.

Steinbacher Plastic and Reconstructive Surgery. 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 [ 12 ].
