Vertical relation and implication of reduced vertical dimension of occlusion on body

The various parameters of maxillomandibular relation are orientation relation, centric relation and vertical relation. Of these, the vertical relation of occlusion has been modified since a long time. Parafunctional habits can lead to generalized attrition, abrasion and loss of molar support and teeth and thereby altering the vertical dimension. Till today the debate about alteration of vertical dimension of occlusion remains. Following is a review on implication of reduced vertical dimension of occlusion on body.
