Overbite | Class II Malocclusion
A malocclusion with the upper front teeth protruding or due to the lower teeth and/or jaw positioned back relative to the upper teeth and/or jaw.

Underbite | Class III Malocclusion
A malocclusion with the lower front teeth protruding or due to the lower teeth and/or jaw positioned ahead relative to the upper teeth and/or jaw.

Deep Bite
This occurs when the upper front teeth overlap the bottom front teeth an excessive amount.

Congenitally Missing Teeth
A genetic occurrence in which the expected number of permanent teeth do not develop.

Crossbite
Upper posterior (back) teeth are in crossbite if they erupt and function inside or outside of the arch in the lower posterior teeth. Lower anterior (front) teeth are in crossbite if they erupt and function in front of the upper anterior teeth. A crossbite can be individual teeth or groups of teeth.

Open Bite
A malocclusion in which teeth do not make contact with each other. With an anterior open bite, the front teeth do not touch when the back teeth are closed together. With a posterior open bite, the back teeth do not touch when the front teeth are closed together.

Crowding
This occurs when teeth do not have enough room to erupt.

Spacing
This may be caused by missing teeth or may be a cosmetic issue.
