Cone beam computed tomography in orthodontics: A literature review

Abstract

3D imaging is quickly emerging as the standard of care in orthodontics as new ultralow-dose CBCT technology offers safer and more affordable volumetric scanning than ever before. Orthodontist routinely use 2-dimensional (2D) static imaging technique, but deepness of structures cannot be obtained and localized with 2-D imaging. Introduction of cone-beam computed tomography (CBCT) for the maxillofacial region provides opportunities for dental practitioners to request multiplanar imaging. This review covers the principles, image acquisition and image reconstruction, various display modes of CBCT and its various application in orthodontics.
