ABSTRACT:
A dental face bow which is readily fittable to a patient's head includes a pair of contact members, such as ear pieces, to be positioned against aural-temporal areas, such as external auditory meatuses, on opposite sides of the patient's head, members to support the contact members, a threaded moving device, which is a thumb wheel operated telescoping unit, for simultaneously moving the supporting members and the contact members nearer together or farther apart, as desired, in a straight line path, in response to rotation of a part of the moving device, e.g., the thumb wheel and auxiliary telescoping means joined to the supporting members for the ear pieces and parallel to the threaded telescoping means, to prevent relative movement of the supporting members. The face bow is adapted to have joined to it universally adjustable mounting means, including a transfer rod, on which a bite index, including a bite plate, may be mounted, which transfer rod, together with the bite index held thereto, is removable from the face bow and readily transferable to a dental articulator in desired bite plate position to aid in mounting a maxillary dental cast.
Also described are: particular types of ear pieces; finger pieces on the face bow to enable a patient to assist in fitting the face bow to his head; means for holding an orbitale pointer in desired storage position on the face bow when the pointer is not in use; an improved transfer rod, including improved means for selectively fastening it to a face bow and to a dental articulator and improved means for assisting in positioning the transfer rod for such fastenings; and an improved universal mounting jig for readily mounting on any of a variety of articulators a bite and transfer rod combination in desired position corresponding to that on the face bow.
