What does “Overbite” mean?
Overbite is the amount by which the upper front teeth overlap the lower front teeth vertically when the mouth is closed.
A term that describes the degree of overlap
Some overlap of the front teeth is present in a normal bite. Excessive overlap is called a deep bite; a vertical gap with no contact is called an open bite. The term “overbite” itself does not always mean excessive overlap.
Distance or ratio and actual contact
It can be recorded as the length of the overlap or the percentage of coverage of the lower front teeth. Along with the readings, we check to see if the lower front teeth are irritating the palate gums, if there is tooth wear and functional discomfort. Overjet, the horizontal front-to-back distance, is also measured separately.
Evaluate front teeth and molars together
The inclination and height of the front teeth, molar contacts, and vertical jaw relationship are assessed together. The goal is not simply to reduce a number, but to establish overlap appropriate to the overall bite and tissue condition. The required tooth movement and retention plan are based on the diagnosis.
Frequently Asked Questions
Is having an overbite abnormal?
No. Normally, the front teeth overlap to a certain extent. The degree of overlap, damage to the gums and teeth, and function are evaluated together.
Is it an overbite if the front teeth come forward?
The horizontal front-to-back distance is overjet. Overbite is the degree of vertical overlap between the upper and lower front teeth.
