History of Orthodontics
Dr. Norman Kingsley was among the first to use extra oral force to correct protruding teeth. The emphasis of this era was to correct facial proportions via extraction of teeth. Very few people of this time had a complete set of teeth. PRESENT Orthodontics uses a combination of extra oral forces to align teeth as well as growth modification, surgery and extractions to accomplish three goals:
1.Create the best occlusal relationship
2.Create acceptable facial esthetics
3.Create a stable occlusal result
