Mystery Of Midline In Facebowtransfer : A Pilot Study.

Location of the transverse hing axis is an important step in mounting the casts on an articulator. The axis of the articulator shaft should coincide with the mandibular transverse hinge axis of the patient. In our routine practice the midline of the wax rim coincides with the midpoint of the face bow fork. A pilot study was carried out to observe the effect of deviation of midline of occlusal rim on the face bow fork in the saggittal plane.
