A more rigid variant, which is more like an arch bar screwed into the bone, may offer additional stabilization in cases with alveolar comminution. These may behave somewhat like an external fixator for the alveolar segment.

Arch bars are applied to the teeth, and MMF is secured. In most cases, heavy elastics or wires are placed for four weeks, followed by lighter training elastics, encouraging a range of motion exercise and a soft or blenderized diet.

Maxillomandibular fixation, also known as arch bars, is a surgical procedure used to immobilize the jaw following trauma or corrective surgery. This is done by placing stainless steel wires and arch bars around the upper and lower teeth, effectively locking the jaw in place while it heals.

Attaining occlusion with an oral endotracheal tube may be difficult; nasotracheal intubation or tracheotomy may be needed. Use of dental wax may decrease lip trauma induced by the arch bars. The arch bars should be removed only after the fractures are healed and stable.

If arch bars or MMF screws are used intraoperatively, they are usually removed at the conclusion of surgery if proper fracture reduction and fixation have been achieved. Arch bars may be maintained postoperatively if functional therapy is required or if required as part of the fixation.

A revolutionary system designed to establish preoperative occlusion and bone reduction. It combines elements of both arch bars and MMF screws in an effort to bring the standard of care for maxillomandibular fixation techniques into the 21st century.

While using Erich arch bars to achieve MMF has remained the gold standard through the last century, the technique has multiple limitations, which have spurred innovative approaches, such as intermaxillary fixation (IMF) screws, hybrid arch …
