The precision of measurement and the stability of the preferred vertical dimension of occlusion in man.
A longitudinal study on the preferred vertical dimension of occlusion (PVDO) established with edentulous subjects shows that these subjects can be divided into two groups, one in which there is significant instability of PVDO, and a second where the instability of PVDO is not greater than can be expected from the imprecision of the PVDO matches. It is concluded that the subjects in the latter group must have referred to a reasonably fixed standard during their PVDO determinations.
