Vertical overlapping of the mandibular incisors by the maxillary incisors when the jaws are in centric (habitual) occlusion.
The usual formation of the teeth, in which the top incisors come down over and in front of the bottom incisors when the jaws are closed.
A type of malocclusion in which the jaw and upper front teeth project too far forward.
Condition in which the upper teeth extend abnormally over the lower teeth.
Overlapping of the lower front teeth by the upper front teeth. A slight overbite is normal because the upper jaw is larger than the lower jaw. An overbite may be caused by tongue thrusting, when a person unknowingly and repeatedly pushes the tongue forward and applies pressure on the front teeth, or by thumb-sucking, which also pushes the top front teeth outward. It may also be caused by hereditary factors that determine the position of the teeth or result in a discrepancy between the length of the upper and lower jawbones. Overbites are treated with orthodontic appliances that bring the teeth into position or the jaws into alignment with dental braces. If the condition is caused by an imbalance in the lengths of the upper and lower jawbones, orthopedic headgear may be worn to decrease the excess length of the upper jawbone or to develop the length of a shortened lower jawbone.
The overlapping of the upper incisor teeth over the lower ones.
A dental term describing the condition where a person’s upper incisor teeth vertically overlap the lower incisors. If serious, the person may need orthodontic correction and this is usually done in childhood after the permanent teeth have developed.
The vertical extension of the incisal ridges of the upper teeth over the incisal ridges of the lower anterior teeth when the jaws are in occlusion.
Overbite refers to the overlap of the upper front teeth over the lower ones. A mild degree of overbite is considered normal due to the natural size difference between the upper and lower jaws. However, in cases of malocclusion, the overbite can be more pronounced than usual, or the lower teeth may extend forward in front of the upper teeth, a condition known as prognathism.
