One really cool feature about Galileos and other CBCT machines is that you don’t have to scan just humans, you can scan stuff and 3D print them! There are a few things you need. First, you need the “Scan Can”. If you are a Galileos Comfort Plus owner you get it for free. If not you can buy it for about $200 from your Galileos Specialist. They should know what it is. In the Sidexis software you can export to “3rd Party Processing” and what you want to do is use the highest resolution possible by closing the “bounding boxes” in the software around the night guard. Export to DICOM and import into a free software called Invesalius, who’s only job is to convert DICOM to STL. You can download at the link below:
Invesalius is really simple. Just import the DICOM images and play with a little slider until everything turns green. Then export to STL. Here is the file in Meshmixer and I used a software called XYZ to add supports and get it ready for my el cheap $495 Wanhao Duplicator I7 printer using FDA approved NextDent Ortho Clear resin. At $249 per L it is the exact same, as proven by the FDA, as the new $495 LT Clear from Formlabs.
Just to have a model, I ran the CEREC stills through ExoCAD’s model builder. Can you do it in Meshmixer? Absolutely, but this is lightning fast and you can also add these little “articulator” extensions which have a “ball and socket” connection to test the occlusion. Also printed on the Wanhao using a resin I am testing from my buddy Cheng Laung Wu!!
With the exception of the supports, there was no adjustments as all with this night guard. I was disappointed to see that it has a very slight yellow cast to it. It was post UV cured for 30 minutes, maybe theres a different way of curing it. I adjusted using the Amazon ceramic burs which can be purchased for $11.99 with free shipping at the link below as opposed to $60 from Axis.
We ended up making him two. This is the occlusion with no adjustment besides removing the supports. He said it fit just like his old night guard, well, because it is just a clone!!!
If you want to know how to use your CBCT to make night guards or just want to know all about 3D printing we will be in Vegas Jan 19/20 for two days of hands on with various printers including the Envisiontec, Moonray and even the Wanhao Duplicator!! Register at the link below:
