Due to living his childhood as handicapped, Stanton's interest gave way to study of orthodontics, where he wanted to focus on correcting malocclusions of children.
He attended Angle School of Orthodontia in 1905 in St. Louis and moved back to New York City to practice as an orthodontist.
In addition, he played a significant part in formation of the journal The American Orthodontist in 1907, which at that time was the first specialized dental publication.
Based on Stanton's efforts to have a study group in order to promote orthodontic thought, Eastern Association of Graduates of Angle School of Orthodontia was formed.
The results of their effort was published in an article named An Instrument for Surveying and Mapping the Denture.
