History of orthodontics

History of orthodontics

Straightening teeth, namely by tooth extraction which helps proper alignment of the teeth was practiced since ancient times, although the branch of dentistry orthodontics appeared only in the 1880s.

According to the American Association of Orthodontists (AAO), archaeologists discovered the mummified bodies of ancient people who were raw metal bands around the teeth, and the Etruscans were buried still wearing the devices used in life to prevent damage teeth and teeth change position. Also, the findings made by a researcher in a Roman tomb in Egypt show some teeth bound with gold wire - the first document of a link.

However, in terms of appearance and evolution of orthodontics, great discoveries came later, around 1800, the credit from many people who have left their mark on the progress of dentistry.
History of orthodontics
First, we should mention the "father of dentistry," Pierre Fauchard (photo), who in his work from 1728 - "Surgeon Dentist" - devote an entire chapter methods of straightening teeth. Fauchard used for straightening teeth a device called "bandits", a piece of precious metal horseshoe shaped what was intended to expand the maxillary arch.

A few years later, in 1757, French dentist Bourdet in turn published a book, "The Art dentist", of which a section was reserved for ways to correct alignment of teeth and also devices used for this purpose. Bourdet, dentist king of France, has perfected the "band" of the Fauchard, being the first premolars extraction recommended to correct "clutter" that has been scientifically proven teeth and jaw growth.
History of orthodontics
Scottish surgeon John Hunter wrote, among other works, "The natural history of teeth" (1771) and "practical treatise on diseases of the teeth," describing in detail the anatomy of the tooth, or dental pathology. He was the one who coined the term "cusp," "bicuspid" "incisive" and "molar."

In 1819, Delebarre introduced in practice clasp wire straightening teeth, and in 1841, Joachim Lafoulon coined the term "orthodontics."

Historians believe that the title "father of orthodontics" to be offered so Norman W. Kingsley, a dentist, sculptor, writer and artist, author of "Treatise on jaw abnormalities" (1880), and JN Farrar, author of two books "Treatise on dental irregularities and ways of correcting teeth." Latter owe the invention of braces, he was also the first to suggest the use of pressure on the teeth at regular intervals to straighten.

Another leading figure in the evolution of orthodontics is Edward H. Angle (1855-1930), who developed the first classification system for malocclusions, a system that is used today. System or offer dentists a simple way to describe how crooked teeth are, what direction they are pointing and how they are arranged in the oral cavity. All Angle is one who, in 1901, founded the first school of orthodontics and organized the American Society of Orthodontics, which became the American Association of Orthodontics in 1930.
In the early 1900s, Orthodontists using gold, platinum, steel, silver, rubber (sometimes wood, ivory, zinc, copper and brass) to manufacture ligatures, hooks and loops used to straighten teeth. The most commonly used was gold (from 14 to 18 carats) due to its malleability. Were made of gold wires, ligatures, clips, while the iridium-platinum alloy sheets were made braces that were fixed on maxillary arch. Gold teeth straightening devices are wrapped around each tooth individually.

In 1929 the first commission was established specialist orthodontic American Commission and the late 1930s, was invented toothbrush with nylon bristles ('38) and stainless steel throughout the '40s began to be used scale. However, using this alloy braces was controversial, being fully accepted in the 1960s.

Before we get to the inventor of Invisalign, braces device "invisible"-should I mention in this History of orthodontics and Dr. New York SC Barnum, who invented the rubber dam (rubber wrap that is used to isolate teeth when a dental), Eugene Solomon Talbot's (1847-1924), who first used radiographs in orthodontics and Calvin S. Case, the first person who used rubber elastic braces.

As braces "invisible," its inventor is Zia Chishti, along with business partner, Kelsey Wirth, founded Align Technology company in 1997, the company manufactures and markets Invisalign appliances. They were sold for the first time in May 2000.
