dimension, vertical

dimension, vertical,

n 1. a vertical measurement of the face between any two arbitrarily selected points that are conveniently located one above and one below the oral cavity, usually in the midline.
n 2. the vertical height of the face with the teeth in occlusion or acting as stops. See also relation, vertical.

dimension, vertical, decrease,

n a decrease of the vertical distance between the mandible and the maxillae by modifications of teeth or the positions of teeth or occlusion rims, or through alveolar or residual ridge resorption.

dimension, vertical, increase,

n an increase of the vertical distance between the mandible and the maxillae by modifications of teeth or the positions of teeth or occlusion rims.

dimension, vertical, occlusal,

n the vertical dimension of the face when the teeth or occlusion rims are in contact in centric occlusion.

dimension, vertical, rest,

n the vertical dimension of the face with the jaws in the rest relation.

dimension, vertical, rest, decrease,

n 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 chronic gum chewers or patients with muscular hypertension.

dimension, vertical, rest, increase,

n may or may not accompany an increase in occlusal dimension. It sometimes occurs after the removal of remaining occlusal contacts, perhaps as a result of the removal of noxious reflex stimuli.
