Invisalign Scanner
Technology







If your initial exam indicates that you would benefit from treatment, we will prepare diagnostic records – orthodontic x-rays, facial photographs and study models. These are used to help diagnose as well as document the health and position of the teeth prior to treatment.

If the patient is ready to start treatment, orthodontic separators will be placed and an appointment will be scheduled to place the orthodontic appliances.

Good morning, I’m Dr. Andy Frost and I am an orthodontist in Creve Coeur, Missouri.
00:12
Our business is straightening teeth, for children and adults.
00:17
The product that we’re discussing today is the iTero Scanner. And the purpose of the
00:21
scanner is to get an exact digital representation of the patient’s teeth for invisalign treatment.
00:29
So traditionally when we would do Invisalign treatment we would make an impression of someone’s
00:33
teeth and then that would be scanned by the Invisalign company. Now, we make an exact
00:39
digital representation with our scanner which is much more accurate than using the two-step
00:44
process of doing the impressions and then the scan. It’s about 10 to 15 minutes to get
00:49
an exact representation.
00:52
The technology has been available for four or five years now and for wide spread use.
00:58
We’ve been using it for about two years.
01:00
Well, Invisalign is becoming more and more available all the time. The company is promoting
01:06
products for younger and younger patients all the time. We use it mostly for people
01:11
who have all of their adult teeth and we haven’t treated anyone younger than about 14 years
01:16
of age using invisalign. I think it’s best used for people who can comply with it well;
01:21
adults who don’t want to wear braces, it’s a very nice alternative.
01:25
So, in order for us to get a high quality scan of the type we need to do the treatment
01:32
properly, we have to isolate the teeth using a retractor. This keeps the cheeks away from
01:39
the teeth as well as taking saliva away which will distort the scan. Now she is working
01:46
on the interior teeth and as she works around the mouth, she will be able to track the scan
01:51
on the computer monitor as she progresses.
01:54
Once she’s worked around the lower teeth, she will move to the upper teeth.
02:09
So, once the patient’s scan has been put into the Invisalign software, I have the ability
02:13
to see how the teeth are going to move during the treatment. So, in this young man’s case,
02:19
you can see that the upper jaw is widened and the teeth are brought back and aligned.
02:26
We can also see it in the front view or the side view so we can see how we want the teeth
02:34
to overlap. The software also shows us where the placement of all of the buttons are
02:41
for this patient’s treatment. These, in real life, are not red but white.


In order to make Invisalign impressions faster, more comfortable, and more accurate, we have a new iTero scanner at the office.

The iTero scanner uses the latest digital scanning and 3D computer modeling technology to construct an accurate digital model of your teeth and your bite. The scanner passes quickly over and around your teeth with little-to-no discomfort and a digital model is produced chairside instantly.

The cutting-edge technology offered by this machine means that we no longer have to use messy and uncomfortable PVS impression material. This cuts the discomfort out of taking impressions and the computer model of your teeth will be more accurate than old impressions ever could be.

Improved accuracy means a drastically lowered chance of fit issues and the need to re-take impressions. One survey found that Invisalign cases using iTero equipment had seven times fewer fit issues and ten times fewer rejections. Plus, using iTero means faster appointments and less time between taking an impression and receiving new Invisalign treatments.

Using a computer model has many advantages over a traditional PVS impression. 3D computer models are constructed instantly, their digital format can be saved and transferred very easily, and they are extremely detailed. The iTero software can even be used to project the results of your Invisalign treatment.

One of the best advantages of the iTero scanner is patient comfort and convenience. Impressions are now faster and easier than ever, with no mess or discomfort.

Invisalign just got even more convenient with our new iTero scanner. To schedule an appointment for Invisalign or other orthodontic treatment, contact Dr. Andy Frost today!
