Abstract
A novel face bow and method of its use for accurately transferring gnathological relationship data from a patient to an articulator, the face bow including radioluscent arm pieces with radiopaque markers or indicators for locating critical points, the method of use comprising the mounting of the face bow on a patient in generally conventional fashion and then producing a cephalometric head x-ray of the patient with the improved face bow in place, the radioluscent arm pieces permitting anatomical features of the patient to be clearly viewed with precise correlation to reference planes. Radiopaque markers are located at various selected points on the face bow to accurately reflect the position of points of interest, such as an articulator's axis of rotation, such that these points become superimposed with the patient's anatomical features on the cephalometric head film.
