The lower teeth protrusion
This type of malocclusion is also called “Class III malocclusion”. The maxilla develops by a small amount compared to the mandible.
The upper teeth protrusion
Malocclusion with protrusion of the upper teeth is also called “Class II malocclusion”. The upper jaw develops in excess relative to the lower jaw (mandible).
Dental crowding
Dental crowding is caused by a discrepancy between the size of the teeth (too large) and the size of the jaws bone (too small), due to hereditary factors.
