The introduction of diagnostic tools, such as cone-beam computed tomography (CBCT) and their clinical application to the 3D craniofacial image is one of the most interesting and pressing issues in orthodontics at present. An update and research is, therefore, required into this topic. Our aim in this manuscript is to explain how the medical CT and CBCT work, to compare their advantages and disadvantages and to explain image processing in order to provide a detailed account of what CBCT represents today in the field of orthodontics.
