overbite

 [o´ver-bīt]
extension of incisal ridges of the upper anterior teeth below the incisal ridges of the corresponding lower teeth when the jaws are closed normally.
Classification of overbite. From Darby and Walsh, 1994.

ver·ti·cal o·ver·lap

1. 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;
2. the distance that teeth lap over their antagonists vertically, especially for the distance that the upper incisal edges drop below the lower ones, but it may also describe the vertical relations of opposing cusps;
3. the relationship of the maxillary incisors to the mandibular incisors when the incisal edges pass each other in centric occlusion.
Synonym(s): overbite

overbite

/over·bite/ (o´ver-bīt″) the extension of the upper incisor teeth over the lower ones vertically when the opposing posterior teeth are in contact.

overbite

(ō′vər-bīt′)
n.
A malocclusion of the teeth in which the front upper incisor and canine teeth project over the lower.

overbite

[ō′vərbīt]
Etymology: AS, ofer, over, bitan, to bite
increased vertical overlapping of the mandibular anterior (lower front) teeth by the maxillary anterior (upper front) teeth, usually measured perpendicular to the occlusal plane. Compare overclosure, overjet.

Overbite

malocclusion of teeth

A form of dental malocclusion in which there is a reversal of the normal relationship of the mandibular and maxillary teeth, with lateral displacement of opposing teeth (i.e., a poor bite) and difficulty in mastication. Normally, mandibular teeth lie inside maxillary teeth and the outside mandibular cusps or incisal edges meet the central portion of opposing maxillary teeth.
 
Complications
Periodontal disease, caries.

overbite,

n a vertical overlapping of maxillary teeth over mandibular teeth, usually measured perpendicular to the occlusal plane. See also overjet and overlap, vertical.

Vertical occlusion was graded according to the coverage of mandibular incisor by the most protruded fully erupted maxillary incisor and was recorded as ideal: if the lower primary incisal edges were contacting the palatal surfaces of the upper primary central incisors in centric occlusion, increased, if the mandibular incisors were touching the palate, open bite, when a gap existed between the incisal edges of incisors along the occlusal plane, and reduced, if the incisal tips of the lower primary incisors were not contacting the upper incisors or the palate in centric occlusion but with positive overbite [9].
