Invisalign IS Rocket Science: History of Invisible Braces

You don’t have to be a rocket scientist to know that invisible braces, such as Invisalign™ are an easy, painless way to get straight teeth.

But, you do have to be a rocket scientist to invent invisible braces. Invisalign™ is made from Translucent Polycrystalline Alumina (TPA), a material developed by NASA’s Advanced Ceramics Research, originally designed to protect heat seeking missiles. [i]

Now, instead of protecting missiles, these clear braces protect and straighten your teeth.

Invisible braces and invisible were first sold in 1987, but their prices were less cost effective than Invisalign™ prices and the procedure was much less precise. At twice the cost, these first generation invisible braces resembled mouth guards, they were cumbersome, ill-fitting and almost as bad as traditional wire braces.

In 1997, Stanford University students Zia Chishti and Kelsey Wirth perfected the Invisalign™ orthodontics procedure. [ii]

The MBA students used high-tech computer imaging graphics to make sure that the invisible braces work exactly like metal braces, without the pain and the constant adjustments.

Here’s a fun fact; neither Chishti nor Wirth had any dental training, they were both traditional braces users that were tired of dealing with teeth issues.

Invisalign™ officially hit the markets in 2000 and instantly became the easiest to use, most popular invisible braces ever.

    This is awesome, what fun facts! I had no idea that my invisible braces were developed ny NASA!

    Invented by NASA – is there anything out there NOT invented by frickin’ rocket scientists? Shouldn’t they be busy getting us to Mars or something?!?!?

    Seriously – pretty cool technology!

    My sister has braces like this. I can’t wait to tell her how they were invented. I hope somethign liek this pops up on a trivia question somewhere so that I can look extra super smart. . .

    Great title! It really drew me in.

    I love the concept behind this, and I love when technology moves laterally to affect all areas of expertise.
    I wonder if those scientists knew they were working on the next best alternative to braces and oral surgery.
