Common Orthodontic Problems

Class II

Class II problems represent an abnormal bite relationship in which the upper jaw and teeth are located in front of the lower jaw and teeth. Class II patients usually exhibit a convex facial profile with a recessed chin. In most cases, this relationship is due to inherited characteristics.

A skeletal Class II problem occurs when the upper back molars are forward of the lower back molars. This gives the patient the appearance of having a recessed lower jaw, a protruding upper jaw, or both.
