Fractures in the tooth-bearing area of the anterior mandible are generally treated first to establish the ideal occlusion. Fractures in the regions without teeth (posterior body/angle/ramus/condyle) are usually treated secondarily.
The angle fracture is most commonly treated with one miniplate fixation along the upper border of the lateral surface of the mandible, and the contralateral fracture through the body/symphysis is treated with more rigid fixation.
Various fixation schemes are available for the fracture of the body/symphysis (eg, two miniplates, a large or extra-large profile 2.0 locking plate, or a reconstruction plate).
