Teeth crowding is the most common orthodontic problem. It occurs when there is an insufficient amount of space for all of the teeth to fit normally within the jaw.

There are many types of dental malocclusion, one of these is spacing. This occurs when there is an excessive amount of space within the jaw, which results in gaps being left between the teeth.

.

Tooth rotation is another form of dental malocclusion. This occurs when the teeth turn or tip away from their normal alignment.

Overjet referrs to the horizontal overlap of the upper over the lower front teeth.

A class I dental malocclusion with anterior crossbite occurs when the upper teeth tilt backwards behind the lower front teeth.

A class III dental malocclusion with anterior crossbite occurs when the lower teeth are positioned further forward than the upper teeth.

The anterior teeth are removed to give a better vew of the posterior teeth. A class III dental malocclusion with posterior crossbite occurs when the upper jaw and teeth are more narrowly aligned than normal. This prevents the upper and lower teeth from fitting together properly.

A normal bite is considered to have a 1 to 3 milimeter vertical overlap between the upper and lower front teeth. An open bite occurs when there is no vertical overlap present.

A normal bite is considered to have a 1 to 3 milimeter vertical overlap between the upper and lower front teeth. A deep bite occurs when this overlap exceeds 3 milimeters.
