Has anyone with a 3d printer tried 3d dentures yet? Would that work?

[–] wizardbeard@lemmy.dbzer0.com 9 points 1 hour ago* (last edited 1 hour ago)

Nope. As far as extrusion printing goes: normal 3D printing filament is not food safe and the tiny stairstep layers would be perfect breeding grounds for bacteria and plaque impossible to properly clean. For resin printing: that shit's toxic in liquid form, very bad idea to ingest as a solid, and dust from the hardened prints (like if you sand a nub down) when breathed in works like asbestos on your lungs.

[–] exasperation@lemm.ee 3 points 1 hour ago

Dental printers are a pretty standard way to make these things. There's a whole regulatory process for testing and certifying the printers and their resins for continued contact with gums/skin/teeth for toxicity, infection, irritation, etc.

But there are still significant drawbacks to using dead synthetic stuff as a replacement for living tissue.

I've been hearing about lab grown teeth for decades at this point. Cool to hear progress regardless though

[–] muhyb@programming.dev 13 points 6 hours ago (2 children)

That's great but how would it connect itself to the nervous system?

[–] betterdeadthanreddit@lemmy.world 44 points 5 hours ago (2 children)

Step one is to let it relax so you're dealing with a calm system instead.

[–] gnutrino@programming.dev 11 points 4 hours ago (1 children)

We have different ideas to put the teeth inside the mouth. We could transplant the young tooth cells at the location of the missing tooth and let them grow inside mouth. Alternatively, we could create the whole tooth in the lab before placing it in the patient’s mouth.

I assume option 1 at least would lead to the nerve connections naturally growing as the tooth does. Regardless, this still seems in the super early lab-proof-of-concept stage so I guess the ultimate answer is we don't know yet.

[–] muhyb@programming.dev 5 points 3 hours ago

Hmm, option 2 seems like root canal treatment but instead there is a new tooth. However if they can predict the direction where the tooth will grow, option 1 seems promising.

[–] Grimtuck@lemmy.world 20 points 6 hours ago

They're going to need to shrink it down, that's way too big.

[–] betterdeadthanreddit@lemmy.world 33 points 7 hours ago (1 children)

Can't wait for the stories about how the fillings are tuned for the new 8G networks and caused COVID-29.

If lab grown teeth give me better reception then I'm all for it!

[–] betterdeadthanreddit@lemmy.world 6 points 7 hours ago (1 children)

Yeah but you have an unskippable 30-second ad whenever you wake up.

[–] MrVilliam@lemm.ee 9 points 6 hours ago

So are you a writer for Black Mirror or a time traveler or...?

[–] PrincessLeiasCat@sh.itjust.works 15 points 7 hours ago (2 children)

I have no doubt that this is a good thing and will improve quality of life, however just the concept itself is the stuff of nightmares.

Teeth…just there….growing….

[–] Tattorack@lemmy.world 8 points 5 hours ago

Honestly, a number of animals have regenerating teeth. Many animals in the past (like dinosaurs) also had regenerating teeth.

Humans are missing out.

[–] Halcyon@discuss.tchncs.de 2 points 6 hours ago

Yeah, thanks, I'll prefer the ceramic implant. Which works fine already.

[–] witty_username@feddit.nl 4 points 5 hours ago (1 children)

Can they grow them with funky colours?

[–] GoofSchmoofer@lemmy.world 4 points 3 hours ago

Give it time and there will be the option of Gigantic Corp paying for your teeth if you grow their logo on them.

[–] WrenFeathers@lemmy.world 59 points 10 hours ago (2 children)

Insurance is guaranteed not to cover this.

Luxury bones!

[–] Supervisor194@lemmy.world 6 points 8 hours ago

And boy it sounds expensive.

[–] MrJukes@lemmy.today 9 points 7 hours ago

Can they make them smaller than the one in the thumbnail? Otherwise, count me out

[–] altphoto@lemmy.today 5 points 7 hours ago

Well hurry up!

[–] osaerisxero@kbin.melroy.org 15 points 9 hours ago

RFK never heard of this, so it couldn't be a real thing

[–] s_s@lemm.ee 5 points 9 hours ago (1 children)

My Labrador has excellent teeth.

Man's best friend becomes man's best mouth.

[–] jabathekek@sopuli.xyz 5 points 8 hours ago (1 children)

are you going to train your dog to chew things for you

[–] I_Fart_Glitter@lemmy.world 7 points 8 hours ago (1 children)

Labrador is happy to chew, will not give back.

[–] fed0sine@lemm.ee 2 points 5 hours ago

Only take!! No give.
