    As someone with 3 very expensive implants and a fourth one coming in the next few months, I was expecting this to be a post about someone making their own teeth that they would use in their own mouth. But that is cool too. Despite the fact that the final product causes me profound repulsion. It looks like a Lovecraftian bio-monstrosity in the beginning stages of replicating a human body.

      "flesh teeth"

      ZBrush or Blender would probably be the best way to clean this model up though. I bet just normalizing the polygon count would remove a lot of the "golf ball texture" on the jaws and teeth, and then just manually cutting and smoothing the remaining bits would go a long way towards making it less horrific. I don't have a lot of experience with sculpting (and only in Blender at that) but that doesn't seem like it would be super hard to clean up and would be a great model to learn on. You could even use your tongue for reference!

      The last time I had dental work done, a technician took detailed scans of my teeth and compiled them into a digital model of my mouth. From that they were able to construct the exact shape I needed for a filling and 3D printed it while I waited. It fit right into place like a puzzle piece. I was blown away by the whole process.

        Are they using additive manufacturing these days? The last time I got a filling done they were using a glorified CNC mill to shape a blank.

          It depends on where you go really - in my experience, a lot of UK dental work is done with traditional methods involving a technician, dremel and a block of ceramic, or a CNC mill like you've described.

          There is a growing number of manufacturers of 3D printers who have developed ceramic printers capable of printing teeth out of zirconia, like the more well know Lithoz, Formlabs, and Stratasys systems, as well as lesser known companies (that i came across whilst double checking the above) like Ackuretta, Asiga and DentaFab. Their usage though is pretty small scale id say - I dont really see examples of the printed teeth at AM exhibitions. There was also a company who had systems that could print the ceramic implants as well as colour match them to the rest of the patients teeth but i cant find the name of it off the top of my head. I believe it was an italian manufacturer.

          Oh that’s a very good question. I was in the other room and didn’t see it firsthand. Probably they were doing the same thing you have experience with. I assume that produces a stronger result than additive printing would, but I don’t know much about this stuff.

          Edit: Just saw @TheDarkerZone’s response, that’s a lot better informed than what I wrote, haha
