hinge-bow,

n the kinematic face-bow used to determine the location of the hinge axis. The hinge-bow is a three-piece instrument with independently adjustable arms controlled by micrometer screws that lengthen or shorten them. Other micrometer screws raise or lower the caliper points to find the spots in or on the skin near the tragi where only rotary movements occur when the jaw is opened and closed at the rearmost point.
