Orthodontic Treatment Types
Crowding |
| Teeth may be aligned
poorly because the dental arch is small
and/or the teeth are large. The bone
and gums over the roots of extremely
crowded teeth may become thin and recede
as a result of severe crowding. Impacted
teeth, poor biting relationships and
undesirable appearance may all result
from crowding. |
|
|
|
|
| A deep overbite or deep
bite occurs when the lower incisor (front)
teeth bite too close or into the gum
tissue behind the upper teeth. When
the lower front teeth bite into the
palate or gum tissue behind the upper
front teeth, significant bone damage
and discomfort can occur. A deep bite
can also contribute to excessive wear
of the incisor teeth. |
|
|
|
Open
bite |
| An open bite results
when the upper and lower incisor teeth
do not touch when biting down. This
open space between the upper and lower
front teeth causes all the chewing pressure
to be placed on the back teeth. This
excessive biting pressure and rubbing
together of the back teeth makes chewing
less efficient and may contribute to
significant tooth wear. |

Overjet |
| Overjet or or upper protruding
teeth is where the upper front teeth
protrudes beyond normal contact with
the lower front teeth. An overjet are
prone to injury, often indicate a poor
bite of the back teeth, and may indicate
an unevenness in jaw growth. Commonly,
protruded upper teeth are associated
with a lower jaw that is short in proportion
to the upper jaw. |
|
|
|
Underbite |
| About 3 to 5 percent
of the population has a lower jaw that
is to some degree longer than the upper
jaw known as an underbite or lower jaw
protrusion. This can cause the lower
front teeth to protrude ahead of the
upper front teeth creating a crossbite.
Careful monitoring of jaw growth and
tooth development is indicated for these
patients. |
|
|
|
Crossbite |
| The most common type
of a crossbite is when the upper teeth
bite inside the lower teeth (toward
the tongue). Crossbites of both back
teeth and front teeth are commonly corrected
early due to biting and chewing difficulties. |

|
Spacing |
| If teeth are missing
or small, or the dental arch is very
wide, space between the teeth can occur.
The most common complaint from those
with excessive space is poor appearance.
