Have you ever fixed your own teeth?

For the stuff that's NOT 4WD related, here's where you can come on in and discuss it, but do play nice!

WTF do you think techs make teeth from? Ceramics still?
Yes, I'd imagine they are a ceramic of some sort. Just like teeth.
And I use a tube of his superglue (not superglue at all) on my fishing knots - like I said, he's a mate. I wear a couple of his crowns.
He also casts my lure heads out of vacuum bagged epoxy at night time for ******* and giggles while he's waiting for the kiln.
He also works with a maxillo facial surgeon (another mate) implanting titanium nutserts into smashed jaws then recreating people's teeth and faces after they have been through windscreens or had cancer, but hey wtf would he know about the products he's made his living from for the last 30 years and now lectures on as well?
Yes, so they're epoxies. Just like I said. Just like knead-it. What was your point? Oh yes, you are telling me that I was right. Thanks for the confirmation.
When your home dentistry goes to crap and you develop an abcess in the jaw sent me a PM, I'll hook you up with some guys who actually know what they are doing.
When?
PHd in chemistry? The material's already invented mate.
I know. That's why I used it. What was your point?
If whatever you are using has polished off in a few days I'd suggest you go find someone who has one or better still just use what the pros use
No doubt the dental product is a different grade. But it's also a whole lot more expensive, without justification. It's just an epoxy. If this one fails I just rebuild it.

BTW it's still holding firm. And I've even now started chewing on it (but only soft stuff)

If you can't afford a dentist your probably only eating 2min noodles anyway. So you'll be fine.

just curious. if you ever needed implants, would you want to save the $280 per screw and buy some stainless steel screws from bunnings. cause they are way more expensive without justification.

Stainless grades are not in the same league as epoxy. People can have a reaction to the nickle content in steel, that's why piercings are available in a number of specific alloys. I would not expect epoxy to be as active from a chemical point of view.

I can see that you're what they call an "ideas man"

I've lost track. Are you the bloke with the friends with the urinary problems? Have they got that seen to yet?

BTW, tooth fix is still going strong. Hey, I'm as surprised as you are......

Thought I'd update this. The original repair finally wore away after 16 months, so I used the same roll of Knead-It to fix it again. More money saved :lol:

Yep fixed my own tooth, not the extreme as this tread but still, Just this Australia day 2016 was holidaying on Moreton Island and my front crown fell off in my hand. So glad i did not swallow it. Well after searching for the Ambo's only to find out they can not assist and they are not even allowed to put stitches in to some poor bugger all they can do basically is put a band aid on, i finally made my way to the shop and purchased some superglue, dried the tooth and crown, two drops and in goes the crown, well that was not pleasant but it did the job and still going strong. $1800 saved.

Yep, superglue is amazing stuff, and is what dentists use to attach crowns anyway.

The reason is works so well is due to the adhesion mechanism. Most glues say that the surfaces must be "dry and free of grease", because if you go down to microscopic level and look at most surfaces they are uneven, wet and dirty. The problem this causes with most glues (that mostly work by adsorption or hydrogen bonding) is that the adhesive sits on top of the oil or water and doesn't interact with the surface very well, so adhesion is linited.

Superglues, however, are water-activated acrylate polymers. That is, water on the surface actually initiates the curing process. If the surface is completely dry it will never set. That's why superglues only work on surfaces that are at least partially hydrophilic, so that they will adsorb moisture from the atmosphere.

So this process kills two birds with one stone - it initiates the reaction quickly, causing it to set in seconds, and also the fact that the reaction sucks up the water means that there is more intimate contact with the adhesive than is normally possible wirth adhesives.

So having cleaned and dried your teeth, you have removed all but the monolayer of water adsorbed to the surface, which is exactly what you want, and the reason why it worked so well.

And yes, Heisenberg aka Chuck Steak. I ran into a problem with logins s omehow, so set up a more chemistry related ID. But I don't make ice....

Superglue is a standard for emergency trauma surgery.

That's right it is the suture material you can use when you don't have sutures available. There is some use in it sticking to skin after all!

Oh yes and for the record the composite that dentists use isn't epoxy resin, it is methracylate resin with a short blue light activated polymerizer, it is not a thermosetting resin. The white colour comes from silica dust.

It is actually closer to the stuff that windscreen repairers use to fix cracks in laminated windscreens. That resin is UV polymerised, but I guess it would be a bit hazzardous for a Dentist to have to wave a UV light around all day.
