what is an overjet
Overjet vs Overbite. These two orthodontic terms are used to describe incisor relationship and are often confused by both patients, parents and sometimes general dental practitioners. Overjet is the measurement (usually in millimetres) between the upper incisal edge and the labial surface of the lower incisors. The normal value is considered to be approximately 2-3 mm but this is increased in Class 2 Division 1 malocclusions and reduced in Class 3 malocclusions.
