Erich Arch Bars, IMF Screws and Hybrid Arch Bars in the Management of Mandibular Fractures
Sponsor: Mansoura University
Summary
Treatment options of mandibular fractures can be accomplished with either closed treatment or open reduction internal fixation (ORIF). Maxillomandibular fixation (MMF) refers to any method used to secure the maxilla and mandible in proper dental occlusion. MMF is a standard component of mandibular fracture management essential for closed treatment and commonly used du ring ORIF. Its three main principles are to establish occlusion, provide stability, and immobilize the jaws.

Conditions
Interventions
Erich Arch Bars
Stainless steel plates with hooks for wire placement are adapted over the facial aspect of teeth so the wires would be inserted to go around the necks of teeth (circumdental wiring), then both maxillary and mandibular plates are ligated to each other in order to achieve MMF.
Hybrid Arch Bars
Screw retained titanium plates with hooks for wires are adapted properly then self drilling self locking screws will be drilled in between roots of teeth to avoid injury, after fixation both jaws will be wired to accomplish MMF
IMF Screws
A total of four self drilling screws two in the maxilla and the other two in the mandible will be inserted in the bone above and below teeth roots apices to avoid injury, to be ligated to each other in a vertical and an X pattern to achieve MMF.
