Angle School of Orthodontia was the first school of orthodontics in the world, established by Edward Angle in 1899. The school taught its students orthodontics over a period of 3–6 weeks. The school graduated 183 students until it closed in 1927.

American Association Of Orthodontists
Founded in 1900, the American Association of Orthodontists (AAO) is the world's oldest and largest dental specialty organization. It represents nearly 19,000 orthodontist members throughout the United States, Canada and abroad. All orthodontists are dentists and may simultaneously hold membership in the American Dental Association. Its headquarters are in Creve Coeur, Missouri, near St. Louis. Orthodontists are dental specialists in the diagnosis, prevention, and treatment of orthodontic problems who have completed two to four years of advanced training in an accredited orthodontic residency program. Only those dentists who have completed this training may call themselves "orthodontists," and only orthodontists may be members of the American Association of Orthodontists. In 2013 Gayle Glenn was elected as the first female president of the American Association of Orthodontists. AAO is affiliated with the Canadian Association of Orthodontists.

Northeastern Society Of Orthodontists
The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography. A compass rose is primarily composed of four cardinal directions— north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and northwest—each located halfway between two cardinal directions. Some disciplines such as meteorology and navigation further divide the compass with additional azimuths. Within European tradition, a fully defined compass has 32 'points' (and any finer subdivisions are described in fractions of points). Compass points are valuable in that they allow a user to refer to a specific azimuth in a colloquial fashion, without having to compute or remember degrees. Designations The names of the compass point directions follow these rules: 8-wind compass rose * The four cardinal directions are north (N), eas ...
