Abstract

Background:  One of the most important achievements of orthodontic therapy is the development of orthodontic records. Record keeping is necessary not only for diagnosis and treatment planning, but also for case follow-up, communication with colleagues, and treatment evaluation. Two-dimensional (2D) imaging technology, like cephalometric and OPG and photos, as well as plaster models, have recently become commonplace. Though, after the advent of three-dimensional (3D) technologies (computed tomography, stereophotogrammetry and laser scanners) into dentistry, 3D imaging systems have become increasingly popular, particularly in cases involving craniofacial deformities. Indeed, 3D imaging offered further accuracy and objective diagnostic details about the craniofacial soft and hard tissue, as well as making 3D analyses simpler, quicker, and more effective. The aim of this review is to give an overview of 3D imaging techniques, as well as their benefits, drawbacks, and the indications for 3D imaging.
