Which type of malocclusion is indicated by an increased overjet measurement?

An increased overjet measurement is indicative of Class II Division 1 malocclusion. In this type of malocclusion, the first molars are positioned in a way that allows the upper front teeth (incisors) to protrude significantly over the lower front teeth, leading to a larger than normal distance between them. This is often due to the upper incisors being either excessively upright or protruded.

Class II Division 1 malocclusion is characterized not only by this increased overjet but also by a deep bite, where the upper teeth overlap the lower teeth more than they should. Patients with this type of malocclusion often have a retruded lower jaw in relation to the upper jaw, contributing to the increased overjet.

Understanding this classification helps dental professionals assess and plan appropriate orthodontic treatment for patients presenting with this dental alignment issue.
