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.
Pseudo Class III
Crowding of the teeth is probably the most common orthodontic problem. Although many factors contribute to dental crowding, this problem typically stems from a discrepancy between the space in each jaw and the size of the teeth.
Crowding is often one of several orthodontic problems. Crowding can be the cause or result of other problems, such as impacted teeth, retained teeth or teeth that do not naturally fall out. Crossbite of the front or rear teeth can also cause the teeth to become crowded.

Narrow upper jaws often cause crossbites, which means a misaligned bite. An anterior crossbite occurs when the narrow upper jaw forces the patient to thrust their lower jaw forward when biting, causing the lower teeth to bite in front of the upper teeth.
During development, this condition is especially damaging as it places additional stress to the TMJ (jaw joint) as it is still growing. We highly recommend correcting an anterior crossbite.
A posterior crossbite will usually result from a narrow upper jaw or abnormally wide lower jaw. A narrow upper jaw will often force a patient to move the lower jaw forward or to the side when closing into a stable bite. When closed into this accommodating position, the lower teeth are located outside the upper teeth.
A posterior crossbite can involve one side of the jaw, known as a unilateral crossbite, or both sides of the jaw, known as a bilateral crossbite.
