What is used to repair fractures to the mandible or maxilla?

Arch bars are commonly used in the surgical repair of fractures to the mandible or maxilla. They serve as a method of provisional fixation, providing support and stabilization during the healing process. The arch bars are typically attached to the dental arches and allow for the application of intermaxillary fixation, which helps to maintain proper occlusion and alignment of the jaw while it heals.

In the context of maxillofacial trauma, arch bars are particularly advantageous because they can be easily applied and removed, making them a versatile choice for managing fractures in this area. They can accommodate various facial fracture patterns and are integral to the stabilization of the dentition during the healing of fractures.

Other options such as screws, plates, and wires may also be used in the repair of facial fractures, but they serve different purposes. Screws and plates are often used in internal fixation methods for more stable constructs, while wires might be used alongside arch bars or for specific fracture types where immobilization is required. However, when considering the question specifically about the primary tool for repair in mandible or maxilla fractures, arch bars are the go-to choice due to their effectiveness in maintaining jaw alignment during recovery.
