Cone-beam computed tomography (CBCT) represents the most recent development of dental imaging. Unlike traditional two-dimensional intra- and extra-oral radiography, CBCT provides high quality three-dimensional images of dental and maxillofacial structures. Typical CBCT images present with axial, coronal, and sagittal slices. With secondary reconstruction, the CBCT data can be reformatted into true panoramic, cross-sectional, and many other craniofacial views. CBCT, such as I-CATTM unit (pictured above), has very short acquisition time and requires very low radiation exposure when compared with conventional CT. Therefore, it is considered as an ideal imaging modality for oral and maxillofacial diagnosis and surgical planning.
