Without significant knowledge of anatomy, and with nerve pathways and anatomical landmarks differing from person to person, people performing mandible piercing procedures often damage important structures when they pass the curved needle up through the skin of the underside of the chin and into the oral cavity. The rami provide articulation points by way of two processes – the coronoid and condyloid (or condylar) processes.
