1) Currently on invisign - mould 24 of 42

2) For 5k (Cdn) - I get 42 moulds, a method used to scan and submit my progress for each mould duration, feedback and advice from a dentist, a scan test to see who they fit

3) Considering the cost of braces and the flexibility these allow (as long as you are disciplined in wearing them) it's well worth it

4) My teeth were really misaligned. At 42 I just decided to do it so I could smile more in pics. Not confidence issue, just sometimes in life you have to do things for yourself

5) You can see the 3d printing lines and its pretty detailed given how lightweight and accurate the shape is for each tooth

6) There are little mounts they install on your teeth for the moulds to latch on to as well, so its not just a fit on the teeth but the mounts as well

7) Each individual mould has a unique number on the package in comes in as well as on the mould. Each package has my name, the dentist and the mould number out of 42.

8) I could see changes starting with mould 6

9) If look even close to mould 42, I will be extactic

10) it also comes with an attachment for your phone that alows you to submit self exams each mould. Its really cool. its very impressive

Tangential, but I have sleep apnea. Fortunately I have it mild enough to get away with a mouthpiece instead of a CPAP (which is good anyway because I also have bruxism).

The mouthpiece works great and I would recommend everyone get tested for sleep apnea if your insurance covers it, but I have to admit that paying for it bothered me. Even with insurance covering some of it, it cost me about $600.

I know that there's a deceptively high amount of engineering required for these kinds of things, but it was very hard to wrap my head around paying $600 for what amounted to a couple pieces of clear plastic. I actually got them to send me the STL of the scan of my teeth, and some back of napkin math indicated that it would have cost me about fifteen cents of resin to print it out myself. Instead I'm paying about 4000x that price.

Obviously this is not apples to apples, I'm sure they're using different and/or better resin that what I have, and as I said there's probably engineering and fine-tuning for this, but even still it was not fun to pay for.

All the same, I sleep like 10x better, so I suppose that considering that $600 is a cheap price to pay.

So shouldn't this really be something that could be opened sourced. I think I've seen a few write ups of people that did their own, but seems like a highly functional implementation could be democratized.

I don’t like this interviewer’s tone, at all. It was like… confrontational but in a teenage way.

There’s a dental procedure in Latin America that is cheaper but only a few places in the US do it.

Most teeth align themselves as kids age. This is almost never necessary.
