Classification of Face

Jaw Bone Issues

It is not sufficient to categorize orthodontic malocclusions on the basis of a classification of the teeth alone. The relationship with other craniofacial structures must also be taken into consideration. Please refer to the Class I, Class II, and Class III information and illustrations below.

Maxillary Dental Protrusion teeth & Mandibular Retrognathism jaws:
These Class malocclusions are more difficult to treat due to the skeletal disharmony and may require orthognathic surgery in conjunction with orthodontic treatment.

Class 3:

Animated face and teeth classification illustration: Mandibular Dental Protrusion
Mandibular Dental Protrusion teeth:
The lower teeth are too far in front of the upper teeth. This malocclusion is treated with orthodontic procedures which may require the extraction of teeth due to the dental protrusion.
