Note: The nasion relator assembly
moves left and right along the crossbar,
and the facebow caliper design allows
the arms to move equal distances during
the opening and closing motions.

Positioning the Facebow on
the Patient
1. Before attempting to place the facebow
onto the bitefork, it is suggested
the operator rehearse the following
procedure with the patient. Caution the
patient that the plastic ear pieces in the
auditory canal will greatly amplify noises
during the procedure.
2. A finger cot placed over each ear piece
will help facilitate proper disinfection of
the facebow.
3. With the bitefork positioned in the
patient’s mouth, slowly slide the transfer
jig on to the bitefork shaft. (Figure 6)
