| gel diffusion precipitin tests in one dimension | Precipitin test's in which antigen solution and antibody incorporated in agar are layered in tubes, permitting effective diffusion in the vertical dimension; the antibody-containing agar may be overlaid directly with antigen solution (single (gel) diffusion in one dimension).

| vertical dimension | The length of the face determined by the distance of separation of jaws. Occlusal vertical dimension (ovd or vdo) or contact vertical dimension is the lower face height with the teeth in centric occlusion. Rest vertical dimension (vdr) is the lower face height measured from a chin point to a point just below the nose, with the mandible in rest position. (12 Dec 1998) |
| rest vertical dimension | 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.

| dimension | 1. Measure in a single line, as length, breadth, height, thickness, or circumference; extension; measurement; usually, in the plural, measure in length and breadth, or in length, breadth, and thickness; extent; size; as, the dimensions of a room, or of a ship; the dimensions of a farm, of a kingdom. "Gentlemen of more than ordinary dimensions." (W. Irving) Space of dimension, extension that has length but no breadth or thickness; a straight or curved line. Space of two dimensions, extension which has length and breadth, but no thickness; a plane or curved surface. Space of three dimensions, extension which has length, breadth, and thickness; a solid. Space of four dimensions, as imaginary kind of extension, which is assumed to have length, breadth, thickness, and also a fourth imaginary dimension. Space of five or six, or more dimensions is also sometimes assumed in mathematics. 2. Extent; reach; scope; importance; as, a project of large dimensions. 3. <mathematics> The degree of manifoldness of a quantity; as, time is quantity having one dimension; volume has three dimensions, relative to extension. 4. <mathematics> A literal factor, as numbered in characterising a term. The term dimensions forms with the cardinal numbers a phrase equivalent to degree with the ordinal; thus, a^2b^2c is a term of five dimensions, or of the fifth degree. 5. <physics> The manifoldness with which the fundamental units of time, length, and mass are involved in determining the units of other physical quantities. Thus, since the unit of velocity varies directly as the unit of length and inversely as the unit of time, the dimensions of velocity are said to be length <divby/ time; the dimensions of work are mass <times/ (length)^2 <divby/ (time)^2; the dimensions of density are mass <divby/ (length)^3. Dimension lumber, Dimension scantling, or Dimension stock, lumber for building, etc, cut to the sizes usually in demand, or to special sizes as ordered. Dimension stone, stone delivered from the quarry rough, but brought to such sizes as are requisite for cutting to dimensions given. Origin: L. Dimensio, fr. Dimensus, p. P. Of dimetiri to measure out; di- = dis- + metiri to measure: cf. F. Dimension. See Measure. Source: Websters Dictionary (01 Mar 1998) |
| occlusal vertical dimension | The vertical dimension of the face when the teeth or occlusion rims are in contact in centric occlusion; decrease in occlusal vertical dimension 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.
