20th century In the early 20th century, Edward Angle devised the first simple classification system for malocclusions, such as Class I, Class II, and so on. His classification system is still used today as a way for dentists to describe how crooked teeth are, what way teeth are pointing, and how teeth fit together. Angle contributed greatly to the design of orthodontic and dental appliances, making many simplifications. He founded the first school and college of orthodontics, organized the American Society of Orthodontia in 1901 which became the American Association of Orthodontists (AAO) in the 1930s, and founded the first orthodontic journal in 1907. Other innovations in orthodontics in the late 19th and early 20th centuries included the first textbook on orthodontics for children, published by J.J. Guilford in 1889, and the use of rubber elastics, pioneered by Calvin S. Case, along with Henry Albert Baker.

'''Today, space age wires, also known as dental arch wires are used to tighten braces but would you believe it if you were told they were made by NASA? NASA made an alloy of nickel and titanium called Nitinol in 1959 to be utilized for solar panels and antennae on their satellites. In1979, an orthodontist by the name, Dr. George Andreasen, developed a new method of fixing braces with the use of the Nitinol wires because they had super-elasticity. Dr. Andereason used the wire on some patients and later found out that he could use it for the entire treatment. He then started using the nitinol wires for all his treatments and as a result, dental doctor visits were reduced, cost for dental treatment was reduced, and patients reported less discomfort.'''
