Which term refers to the vertical overlap of the incisors when the jaws are closed?

Explanation:
Vertical overlap of the upper incisors over the lower incisors when the jaws are closed is called an overbite. It describes how much the upper front teeth cover the lower front teeth in the vertical direction. A normal bite has some overlap, while an excessive overlap is often called a deep bite. If there were no vertical overlap at all, that would be an open bite. Overjet refers to how far the upper incisors project in front of the lower incisors horizontally, and crossbite is when the upper teeth bite inside the lower teeth across the arch. So the term for vertical overlap is overbite.
