3D Printing in Orthodontics

3D printing in Orthodontics at Riolo Orthodontics

At Riolo Orthodontics we employ a number of different 3D printers using different printing technologies

We use our 3D printers to create retainers, aligners to move teeth without metal braces on the front of the teeth as well as many other orthodontic appliances. Combined with the 3D digital scanner we can create models of your teeth that are much more accurate than traditional impressions. As a result this method of capturing your tooth anatomy will create a more accurate retainers compared to the traditional method of taking a mold of your mouth. At the time you get your retainer you will also receive the 3D printed model of your teeth. This model can be brought in to make a new retainer if you lose your retainer or your dog happens to chew it. We also keep a digital copy of your teeth that can be reprinted if you happen to lose both your retainer and 3D printed model.

How the 3D printer works

First, we acquire a scan with our intra-oral digital scanner. Next the file is edited to have a base added and holes in the surface mesh are repaired. After the file has been edited it is uploaded to the 3D printer. Our Printer employs either SLA (Stereolithography) or DLP (Digital Light Projection) printing technology which hardens resin with a ultraviolet laser in very small layers building upon each other. After the print the build supports of the model are removed. The model is then cleaned using isopropanol. This 3D printing technology is used in the production many orthodontic appliances including Invisalign.

The benefits of the 3D printer for patients

The intra-oral scanner is less invasive and more accurate than the traditional impressions. Since the these digital models are printed in house we can turn these models around the same day!  We now have the ability to produce retainers the same day as the braces are removed.  This means there is no chance the teeth will move before you get your retainers. The 3D scan and 3D printing is also more accurate than impressions so the retainer will fit your teeth perfectly.  We use this technology to produce Movement Aligners, Clear Aligners specifically design for each of our patients to align their teeth as quickly and efficiently as possible.

We teach this technology to dentiat and orthodontists.  If you are interested in learning more you can contact us at TheToothMovement.
