rest vertical dimension

rest ver·ti·cal di·men·sion

the vertical dimension of the face with the jaws in rest relation; decrease in rest vertical dimension may or may not accompany a decrease in occlusal vertical dimension; it may occur without a decrease in occlusal vertical dimension in patients with a preponderant activity of the jaw-closing musculature, as in patients with muscular hypertenseness or in chronic gum chewers; increase in rest vertical dimension may or may not accompany an increase in occlusal vertical dimension; it sometimes occurs after the removal of remaining occlusal contacts, perhaps as a result of the removal of noxious reflex stimuli.

Facial measurement with jaws in rest relation; a decrease may or may not accompany decrease in occlusal vertical dimension; may occur without a decrease in occlusal vertical dimension in patients with a preponderant activity of jaw-closing musculature, as in patients with muscular hypertenseness or in long-term gum chewers; increase may or may not accompany an increase in occlusal vertical dimension; sometimes occurs after removal of remaining occlusal contacts, perhaps as a result of the removal of noxious reflex stimuli.

Reconstruction of the atrophic, avulsed, or tumor affected mandible must take consideration of the rest vertical dimension (OVD + freeway space) and occlusal vertical dimensions, and from this study, bone graft heights of 2.0 cm to 3.0 cm will be sufficient to maintain the occlusal vertical dimensions in many patients.
These alterations will be individual specific and it will have effect on the rest vertical dimension, TMJ loading, tooth loading, and neuromuscular stability [12].
