The author addresses whether the face bow is irrelevant for all types of prosthetic work and for planning orthognathic surgery.', 'The author searched electronic databases to find studies whose investigators used the strongest clinical evidence (that is, randomized clinical trials) and studies whose investigators incorporated the use of cinefluorography. The author found 13 studies and 1 Internet video that provided strong evidence to support the irrelevancy of the face bow transfer.', 'Evidence indicates that the face bow has nothingto do with speech, the fit and comfort of the prostheses, ridge morphology, facial contours, the color ofthe teeth and denture bases, the arrangement of the artificial teeth, chewing efficiency stability, and the psychological aspects of prosthodontic treatment. The cinefluorographic example showed that there was no condylar axisof rotationduring functional activity, a sawing action of themandibular incisors during the incising oftoast andthemandible moving in a back and forth,rockingchair-like movement during functional activity.
