The practice of orthodontics has always been a blend of art and science. For nearly a century, from the early 1900s to the dawn of the 21st century, the fundamental tools of the trade remained remarkably consistent: metal brackets, archwires, elastics, and two-dimensional radiographic films. The orthodontist's eye, guided by experience and training, was the primary diagnostic instrument, and the movement of teeth was achieved through mechanical force systems that had changed little since the time of Edward Angle.
