Overbite is often confused with overjet, which is the distance between the maxillary anterior teeth and the mandibular anterior teeth in the anterior-posterior axis. "Overbite" may also be used commonly to refer to Class II malocclusion or retrognathia, though this usage can be considered incorrect. This is where the mesiobuccal cusp of the ...
This describes the incisal relationship where there is both zero overjet and zero overbite, and where the incisal edge of both upper and lower central incisors are in direct edge to edge contact. It is considered a traumatic bite in that it accelerates wear and abnormal acquired incisal form, and unaesthetic smile development.
2.a Increased Overjet >3.5 mm but ≤6 mm (with competent lips) 2.b Reverse overjet greater than 0 mm but ≤1mm 2.c Anterior or posterior crossbite with ≤1mm discrepancy between retruded contact position and intercuspal position 2.d Displacement of teeth >1mm but ≤2mm 2.e Anterior or posterior open bite >1mm but ≤2mm
Class II (Distocclusion (retrognathism, overjet, overbite)): In this situation, the mesiobuccal cusp of the upper first molar is not aligned with the mesiobuccal groove of the lower first molar. Instead it is anterior to it. Usually the mesiobuccal cusp rests in between the first mandibular molars and second premolars. There are two subtypes:
Anterior open bite resulted from tongue thrusting in a 24 y.o. patient. Anterior upper teeth are not touching their counterpart. Anterior open bite (AOB) is defined as a condition in which there is no contact and no vertical overlap of the lower incisor crown with the upper incisor crown when the mandible is in full occlusion.

An overbite of 3-5mm [2] and an overjet of 2-3mms are considered to be within the range of normal. [ 13 ] To look at the ICP, articulating paper should be placed on the occlusal surface and the patient asked to bite together, which will mark their occlusal contacts.

A posterior crossbite can be unilateral, bilateral, single-tooth or entire segment crossbite. Posterior crossbite has been reported to occur between 7–23% of the population. [8] [9] The most common type of posterior crossbite to occur is the unilateral crossbite which occurs in 80% to 97% of the posterior crossbite cases.
