Orthodontics
- Non Extraction
Non-extraction orthodontics is a popular choice for patients who wish
to straighten teeth without having to remove any natural permanent
teeth. During non-extraction orthodontic treatment, Dr. G Chammas
will attempt to correct tooth crowding through permanent remodeling
of the bones of the jaw.
This may include the use of functional appliances
much like retainers to non-surgically achieve a beautiful broad smile.
Non-extraction orthodontics also may allow patients to spend less
time in braces. All these things can be done with minimal or no discomfort
and without surgery.
Extraction versus Non-extraction
The treatment of irregular teeth has evolved over the last century,
largely by trial and error. Many types of treatment have been tried
during this period, most of which have been superseded. Most treatment
has been based on two underlying alternatives.
Accept that the jaws are too small and extract teeth to provide the
space.
Enlarge the jaws to accommodate the teeth.
Over the last 100 years treatment has alternated between these two
concepts and there have been decades when no orthodontists extracted
teeth and decades when they all extracted teeth. At the moment most
countries are leaving a period of extraction but some are moving towards
it. This might suggest a degree of discontent with both methods.
Both methods work well in the short term but unfortunately tend to
fail in the long term with re-crowding of the teeth. In Europe teeth
are extracted in around 75% of cases while at the moment in Australia
it may be closer to 60%. Most orthodontists will say they extract
teeth only when absolutely necessary, but clearly there is considerable
disagreement about when this might be so. Whatever the treatment very
few patients treated by these methods finish with all their teeth
and a large proportion loose eight teeth as there is not room for
the wisdoms.
Some orthodontists avoid extractions by pulling the side teeth back
with a strap aground the back of the head or neck, so making room
to straighten the front teeth. However this tends to reduce the room
for the wisdom teeth. It also encourages downward growth of the face
and there is no doubt that this can damage the face, sometimes severely.
