Hinge axis is defined as an imaginary line passing through the two mandibular condyles around which the mandible rotates without translatory movement. Face bow helps to relate the arc of closure or hinge axis of the mandible to the cranium. It records the opening & closing path of movement. Face bow transfer is an integral part in analyzing & studying the occlusion. Face bow record helps in securing anteroposterior positioning of cast in relation to condyles. It also helps in achieving the exact anteroposterior or vertical positioning of cast in relation to condyles.
