Which type of fracture is treated with arch bars?

Arch bars are specifically designed for stabilization of mandibular fractures. These bars are typically made of stainless steel and are affixed to the teeth through dental wire, creating a framework that helps in alignment and immobilization of the mandible during the healing process. This method is essential since proper occlusion (the way the upper and lower teeth come together) must be maintained, which is crucial for function and aesthetics.

The other types of fractures listed do not require arch bars in their standard treatment. Nasal fractures are generally treated with external splints or splinting materials, zygomatic fractures may involve plates or screws to stabilize the bone, and orbital fractures may involve different surgical techniques such as the use of implants or sutures but do not utilize arch bars. Therefore, the use of arch bars is specifically tailored to address the unique requirements of mandibular fracture stabilization.
