Relevant Bony Anatomy

The mandible (jawbone) is the bony structure of the lower jaw and lowest aspect of the face. It is the largest and strongest of the facial bones and provides sockets (known as alveolar processes) to hold the lower teeth in place. The mandible primarily acts to support the lower aspect of the face, provide a fixation point for the lower teeth, allow jaw movement during speech and mastication (chewing) and is essential for other movements of the mouth (such as yawning).

The mandible forms the lower aspect of the skull and consists of two parts: a horizontal part called the body, and two vertical parts called rami which ascend almost vertically from the back of the mandibular body. The top of each ramus contains two bony prominences known as the condylar and coronoid processes.
