- occlusal vertical d. the vertical d. of the face when the teeth or occlusion rims are in contact in centric occlusion; decrease in occlusal vertical d. may result from modification of tooth form by attrition or grinding, drifting of teeth, or, in edentulous patients, by resorption of residual ridges; increase may result from modifications of tooth form, tooth position, height of occlusion rims, rebasing or relining, or occlusal splints.- rest vertical d. the vertical d. of the face with the jaws in rest relation; decrease in rest vertical d. may or may not accompany a decrease in occlusal vertical d.; it may occur without a decrease in occlusal vertical d. 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 d. may or may not accompany an increase in occlusal vertical d.; it sometimes occurs after the removal of remaining occlusal contacts, perhaps as a result of the removal of noxious reflex stimuli.- vertical d. a vertical measurement of the face between any two arbitrarily selected points which are conveniently located, one above and one below the mouth, usually in the midline. SYN: vertical opening.
