/diy/ - Do It Yourself

This isn't rocket science. Teeth move under pressure. I'm going to apply that pressure, and move 2 of my teeth in opposite directions, about 2 millimeters, over the course of several years.

Why? What will go wrong?

This is basically the same process as actual invisalign uses, just DIY.

DIY orthodontics.

The problem:
My teeth are crooked. My right central incisor is pushed inwards, while my right lateral incisor (right next to it) projects outward. I had braces when I was a teenager, but since then these two teeth have drifted in opposite directions, about 2-3 mm. I don't have money for braces again. All my other teeth are still in their correct locations, it's just these two.

The solution:
I have a 3d printer. I'm going to 3d print my own "invisalign."

1. Make a mold of my teeth.
2. 3d scan the molded resin..
3. Create a 3d model of my palate, with each tooth as a separate moveable object.
4. I'm going to create a set of 20 or so 3d prints of my teeth, in the positions interpolated between their current position.
5. I'm going to use Shapelock/instamorph thermoplastic to make a smooth invisalign-style retainer for each of the 3d prints.

Since only 2 of my teeth are out of alignment, I will be anchoring the retainers on the other teeth.

I have the 3d modeling/scanning skills required, and I have the 3d printing capability. I don't know about molding. How do I make an impression/mold of my teeth for the initial 3d scan? Whats a good cheap pourable plastic or resin for this initial impression?

Also, does anyone on here have any orthodontic knowledge? I need to know more about the time frame for teeth movement, to determine how often to switch retainers and how much movement to plan out for each retainer. Should the movement be linear over time, or does it need a period of initial acceleration?

I considered 3d printing the retainers, but I think Shapelock will be better because it's smoother than PLA, more flexible, and potentially less toxic (and definitely less toxic than ABS).
