| vertical osteotomy | An oral surgical procedure similar to sliding oblique osteotomy. (05 Mar 2000) |
|---|---|
| vertical overlap | The extension of the upper teeth over the lower teeth in a vertical direction when the opposing posterior teeth are in contact in centric occlusion, the distance that teeth lap over their antagonists vertically, especially for the distance that the upper incisal edges drop below the lower ones, but may also describe the vertical relations of opposing cusps, the relationship of the maxillary incisors to the mandibular incisors when the incisal edges pass each other in centric occlusion. Synonym: overbite. (05 Mar 2000) |
| vertical parallax | The relative vertical displacement of the image when each eye is closed in turn; seen in vertical diplopia, or heterophoria. (05 Mar 2000) |
| vertical plate | Flat portion of a bone which lies within or closely approximates a vertical plane. See: perpendicular plate of ethmoid bone, perpendicular plate of palatine bone. Synonym: lamina perpendicularis, pars perpendicularis, vertical plate. (05 Mar 2000) |
| vertical retraction syndrome | <syndrome> A retraction of the globe and pseudoptosis on attempted adduction; due to co-innervation of the horizontal recti. Sometimes there is an inability to abduct the affected eye (type 1), or adduct the affected eye (type 2), or both (type 3). Synonym: Duane's syndrome. (05 Mar 2000) |
| vertical strabismus | A form of strabismus in which the visual axis of one eye deviates upward (s. Sursum vergens) or downward (s. Deorsum vergens). (05 Mar 2000) |
| vertical transmission | <microbiology> Transmission of a pathogen such as HIV from mother to foetus or baby during pregnancy or birth. See: perinatal transmission. (09 Oct 1997) |
| vertical vertigo | Dizziness experienced when standing upright. (05 Mar 2000) |
| 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. (05 Mar 2000) |
| Scardino vertical flap pyeloplasty | A reconstructive technique for correction of uteropelvic obstruction, whereby a vertical flap of renal pelvis is brought down and interposed into a vertical incision in the ureter. Compare: Culp pyeloplasty. (05 Mar 2000) |
| disease transmission, vertical | The transmission of infectious disease or pathogens from one generation to another. It includes transmission in utero or intrapartum by exposure to blood and secretions, and postpartum exposure via breastfeeding. (12 Dec 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. (05 Mar 2000) |
| alveolobuccal sulcus | The upper and lower half of the buccal vestibule on each side. Synonym: alveolobuccal sulcus, gingivobuccal groove, gingivobuccal sulcus. (05 Mar 2000) |
| alveololabial sulcus | The upper and lower half of the labial vestibule, in the embryo, the groove formed by the deepening of the labial sulcus; its inner wall becomes incorporated with the alveolar process of the mandible or the maxilla, and its outer wall with the lips and cheeks. Synonym: alveololabial sulcus, gingivolabial groove, gingivolabial sulcus. (05 Mar 2000) |
| alveololingual sulcus | That part of the oral cavity proper, on each side of the frenulum linguae, between the tongue and the mandibular alveolar process or ridge, in the embryo, the groove on each side between the lingual primordium and the alveolar elevations of the mandible. Synonym: alveololingual sulcus, gingivolingual groove, gingivolingual sulcus. (05 Mar 2000) |
