Invisible Braces are use by kids and adults every day
Why did Nasa make Invisible Braces?
Ceradyne Inc. with the help of NASA. invented the material made out of invisible braces. The braces are made out translucent polycrystalline alumina which was originally made to protect the infrared antennae of heat- seeking missile trackers .In other words, NASA wanted to create a tougher and stronger material for their spacecrafts and aircrafts. This was not used on a particular mission but it was used for most missions.
Then other company. Unitek was trying to make less visible braces. They decided that the material would be strong and
clear for the braces.
The material that invisible braces are made out of can be used on aircrafts or spacecrafts even though there are better materials. The materials can also be used on some trucks that need a strong outer layer because the material is very tough and strong. The material can be used under the truck and on the sides to protect it.
How we use Invisible Braces today?
They are the same size and shape as metal braces, except that they have tooth-colored or clear brackets that blend in to teeth. Some even use tooth-colored wires to be even less noticeable.
