Incisor Classification - bite of the front teeth
Although teeth come in many different arrangements, it is possible to classify them by common patterns based on the appearance and bite of the front teeth. There are 4 categories in the British incisor classification (these differ from the American Angle's classification).
- Class I - nearly normal bite of the front teeth
- Class II, division 1 - protrusive upper front teeth, probably the commonest in the U.K.
- Class II, division 2 - upper front teeth tipped back, unusual
- Class III - reverse bite of the front teeth (underbite) uncommon
|Class I||The bite of the front teeth is normal - the teeth may appear either crowded or spaced|
|Class II division 1||The upper front teeth protrude away from the bottom teeth - also known as buck teeth and goofy teeth|
|Class II division 2||The upper front teeth slope backwards|
|Class III||The lower front teeth bite in front of the upper front teeth - also known as an under-bite|
|Hypodontia||Developmentally missing teeth|
|Adult||Orthodontic treatment for the non-growing patient|
