Intra-dental wires (embrasure) are the simplest and fastest form of MMF to implement.
It may be used for simple mandibular fractures in patients with good dentition.
Because of the wires' large gauge, caution must be used when any of the teeth are loose.
One pitfall when using arch bars is the risk of contamination of bloodborne infection from patients. Passing the wires to secure the arch bar can result in a puncture or tear in the surgeon's glove and the possibility of disease transmission to the surgeon.
Universal infection control shall be ensured for every patient, regardless of the disease status of the patient. Adequate protective barriers, as well as techniques, are essential to prevent prick accidents.
Use of double gloves. The lower number of perforations in the inner gloves demonstrate the effectiveness of double gloving.
A thicker gauge wire (eg, 0.64 mm) is passed through the maxillary and mandibular teeth' interdental space. A minimum of one wire on each side of the mandible should be used.
When all the wires are passed, they are tightened with the patient in occlusion.
ORIF is then performed, and the wires are removed at the end of the case.
Due to the difficulty of removing these large wires, it is not recommended to leave them in postoperatively.
