Overview

overbite


Show Summary Details

Quick Reference

The vertical overlap of the incisor teeth. It is described as average, when the upper incisors overlap the lower incisors by a third of their height, reduced when the upper incisors overlap the lower incisors by less than a third of their height, or increased when the upper incisors overlap the lower incisors by more than a third of their height. An overbite can also be described as complete where there is contact between the lower incisors and either the upper incisors or the junction of the teeth with the palate, or incomplete where the lower incisors make no contact with the opposing upper incisors or the palatal mucosa when the buccal segment teeth are in occlusion. Compare overjet.
