Controlling the Vertical Dimension
Volume 51 : Number 7 : Page 375 : Jul 2017
The vertical dimension of the face, or facial height, is one of the more esoteric concepts in dentistry. The online Medical Dictionary defines it as "the linear dimension in the midline from the hairline to menton." Anterior facial height is rather self-evidently described as "the sum of upper and lower facial heights, the lower limit of the latter variously defined as the pogonion, gnathion, or menton. Posterior facial height is often measured from the gonion to the condylare, sella, or center of face point." The occlusal correlate of facial height is the vertical dimension of occlusion (VDO).
