  • Patent number: 4419077
    Abstract: An improved orthodontic face-bow and method for preventing eye and facial injuries. The face-bow applies force to a patient's teeth through an orthodontic arch wire fixed to the patient's teeth. The face-bow comprises a frame having a pair of rearwardly extending arms each terminating in hooks at their rear ends and in a central frame portion at their forward ends. Rearwardly or upwardly extending spaced levers with forked ends are secured to the frame adjacent. The levers are removably connected to the arch wire. The face-bow includes an auxiliary arch wire secured to the frame adjacent the central frame portion. The auxiliary arch wire comprises auxiliary arms extending rearwardly from the central frame portion. The ends of the auxiliary arms are removably positioned in association with a buccal tube fixed to a molar. The auxiliary arch wire prevents accidental removal of the face-bow from a patient's mouth, thereby to prevent eye and facial injuries.
