Eight constituent organizations exist throughout the United States and Canada. AAO members must meet the educational requirements of the Council on Dental Education of the American Dental Association in order to become a specialist in orthodontics. AAO members must have at least two academic years of advanced education in an accredited program. Inside its national office, the AAO maintains the Charles R.
