In search of anatomic truth: 3-dimensional digital modeling and the future of orthodontics.

The goal of imaging in medicine and dentistry has been to display a patient’s anatomic truth. Until now, imaging technology has been largely confined to 2 dimensions. Some 3-dimensional (3D) imaging techniques have been developed, but they are limited by the amount of information they can display and by their static nature. The development of an interactive 3D digital model of a patient’s anatomy would greatly improve our ability to determine different treatment options, to monitor changes over time (the fourth dimension), to predict and display final treatment results, and to measure treatment outcomes more accurately.
