In November of 1899, he taught a Postgraduate course on orthodontia in his office in St. Louis where his students urged him to create a school for teaching Orthodontics. He founded the Angle School of Orthodontia in St. Louis, Missouri 1900, where he formally established orthodontics as a specialty. With Angle the specialty of orthodontics received a new impetus. He coined the term malocclusion to refer to anomalies of tooth position and classified various abnormalities of the teeth and jaws, invented appliances for their treatment and devised several surgical techniques as well. Angle standardized appliances in a series of books and pamphlets, including a text that he authored, Treatment of Malocclusion of the Teeth and Fractures of the Maxillae: Angle's System.
His increasing interest in dental occlusion and in the treatment necessary to obtain normal occlusion led directly to his development of orthodontics as a specialty, with himself as the "father of modern orthodontics".The development of Angle's classification of malocclusion in the 1890s was an important step in the development of orthodontics because it not only subdivided major types of malocclusion but also included the first clear and simple definition of normal occlusion in the natural dentition.
Angle was concerned with the aesthetics of orthodontics as well as functionality and so he collaborated with the artist and art educator Edmund H. Wuerpel in applying aesthetics to his field. The artist and dentist collaborated for many years and Wuerpel lectured frequently at Angle's request, in St. Louis as well as in Pasadena.
The Angle Orthodontist, founded in 1930, is the official publication of the Edward H. Angle Society of Orthodontists, society established in 1922, and is published bimonthly in January, March, May, July, September and November by The EH Angle Education and Research Foundation Inc. In 1901, he also founded the Society of Orthodontists which later became American Society of Orthodontists.
Edward Angle has 46 patents to his name.
