Major Problems
Major Problems:
Increased Overjet - When the upper teeth are too out of the lower;

Crossbite - When the upper teeth are inside the lower;

Open bite - When posterior teeth are in contact and there is a space between the upper and lower anterior teeth.

Deep bite - when your upper teeth cover too much the lower teeth.

Misalignment of the midline - when the line passing through the anterior-superior teeth is not aligned with the line between the lower anterior teeth.

Diastema - When there's spaces between teeth.

Crowding (lack of space) - When there is no space in the dental arch to accommodate the teeth.

Impacted teeth - teeth that do not erupt. This happens sometimes with the canine tooth. It's necessary surgical exposure of the tooth. Then the tooth is pulled to the arcade with the braces.

Classification of malocclusion (Angle):
The malocclusions are classified by classes, Angle, according to the ratio of the teeth of upper jaw with the lower jaw, given by the position of a molar. Class I is normal and class II and III pathological.
| Class I | Class II - Division I |
