Underbite Correction Time Lapse Video
This video is an example of a patient that had a severe underbite. It shows a frontal view of the teeth and how their positions changed with treatment. An underbite results from either a small upper jaw, a large lower jaw, or a combination of the two. In an underbite, the lower front teeth are in front of the upper front teeth. The correction of the underbite was achieved without a jaw surgery by using a facemask (reverse pull headgear) and having two lower bicuspids removed. The upper dental arch was narrow, so a palate expander was also used.
It should be noted that this kind of treatment can only be performed on a growing child. The facemask (reverse pull headgear) actually makes the upper jaw grow forward more. Once a girl reaches the age of 13-14 years of age or a boy reaches the age of 15 years old this type of treatment is not effective. Often, it is easier to do this type of treatment on kids when they are 8-9 years old. They are much more compliant with wearing the facemask at that age than teenagers are.
