The British Orthodontic Society dates its origin to the unification in 1994 of the British Society for the Study of Orthodontics (BSSO), which was founded in 1907, with four other national orthodontic societies, the Consultant Orthodontists Group, the British Association of Orthodontists, the Community Orthodontists Section and the Association of University Teachers of Orthodontics.
