3D Imaging in Orthodontics – A Narrative Review

Abstract

Three-dimensional (3D) technology has been widely used in orthodontics in recent years. Conventional computed and
cone-beam computerized tomography (CT/CBCT), ultrasonography (USG), magnetic resonance imaging, and surface
scanning, intraoral scanning are some of the 3D technologies in orthodontics. The purpose of this article is to review the
currently available orthodontic appliances which utilizes 3D technology such as the principles in 3D imaging and its possible
applications of 3D facial imaging in orthodontics, the different techniques of 3D imaging of the teeth as well as the recent
efforts to create the “virtual orthodontic patient” with the help of 3D soft- and hard-tissue data. This article is basically a brief
narrative review of some of the commercially available 3D-based technologies in orthodontics.
