is a revolutionary system for straightening crooked
teeth and closing gaps between teeth in many cases
can replace the need for traditional metal-wire braces
that have long been used in traditional orthodontic
practice. The system utilises the latest in computerised
technology and three dimensional modelling to generate
a series of clear, see-through aligners or “clear
braces”. They are virtually un-noticeable when
you are wearing them and are often referred to
by many patients as “Invisible Braces”.
The Clear aligners are specially fabricated to fit
your teeth exactly and over time they slowly move
your teeth into a position that gives you a natural
looking straight smile.
So how does the Invisalign
system work? Its simple :
- You wear your aligners for 22 hours a day
- You remove your aligners to eat and brush your
- As your teeth move slowly over time
- You change your aligners approximately every
- Have regular progress checks with your dentist
- Full treatment takes from 6 months to a year
(sometimes 18 months).
Can Invisalign be used
for all orthodontic cases?
For the majority of crooked teeth problems including,
overbites, underbites, crowding, crossbites and gaps
between your teeth Invisalign works very well. However
more severe orthodontic cases where perhaps teeth
extraction is required or there is a lot of movement
needed then Invisalign may not be appropriate. During
your free consultation your dentist will be able to
tell you if you are suitable for Invisalign. In very
severe cases traditional wire braces, friction free
Damon braces or lingual braces may need to be used
to correct your tooth alignment.
What is the procedure?
1. After an initial consultation and assessment of
your smile and teeth alignment your Invisalign dentist,
will take an impression (mould) of your teeth using
a special “dental putty” and take several
photographs of your teeth and smile from different
2. A 3D digital model of your teeth is then created
at the Invisalign laboratory using a CT scanner.
3. Using the latest patented software the model is
used as a basis to generate a simulation of your teeth
movement from their current position to the final
4. This simulation is then used as the basis to design
your aligners, custom made for your teeth and to be
changed every two weeks as your teeth move little
5. Your newly fabricated aligners will then be sent
back to your dentist along with the 3D simulation
so that you can see for yourself the expected movement
of your teeth over time.
6. Your dentist will give you strict instructions
on how to use the aligners, they must be worn for
a minimum of 20 hours a day, the success of the treatment
is highly dependent on your compliance as a patient
and so requires dedication.
7. You will have regular checkups with your dentist
to ensure that your treatment is going as initially
How much does Invisalign
This depends on the severity of your case, where you
go for the treatment and the skill of your dentist
/ orthodontists. During your Free consultation you
should be given an accurate indication of likely costs
for your particular case.
