title: Orthodontics in 3 millennia. Chapter 2: entering the modern era.
abstract: In the early 1900s, groundbreaking scientists, working without benefit of graduate training and having little precedent, built the orthodontic edifice brick by brick. Kingsley pioneered cleft-palate treatment. Case showed us the importance of facial esthetics. Dewey and Ketcham made the ABO the first certifying board in dentistry. But it was Angle who gave us our first school, journal, society, and practical classification of malocclusion.
