Overbite refers to the extent of vertical overlap of the maxillary central incisors over the mandibular central incisors; it does not refer to a lower jaw being too far behind the upper jaw (retrognathia) or a misalignment of the teeth.

Overbite is measured relative to the incisal edges of the upper and lower incisor teeth. Normal overbite is about 1-2 mm, or 10-25 %, as it can be expressed in both millimetres and percentage.
