Ramus fractures

Aside from the condylar process and angle fractures, other fractures occur within the mandibular ramus. These may be horizontal, vertical, or comminuted fractures; and are usually minimally displaced. Fractures through the ramus of the mandible are comparatively rare.

Most ramus fractures do not cause a significant malocclusion because the pterygomasseteric sling maintains the fragments' position.

This panoramic radiograph shows a linear, complete, minimally displaced, horizontal fracture of the right mandibular ramus. There is also a fracture of the mandibular symphysis.
