CONE-BEAM COMPUTED TOMOGRAPHY IN ORTHODONTICS – A REVIEW

Abstract

Radiographic imaging is an important part of orthodontic diagnosis and treatment planning. Cone Beam Computed Tomography (CBCT) is a diagnostic imaging technology designed to produce undistorted three-dimensional images similar to computed tomography (CT) but at low equipment cost, simpler image acquisition, and lower patient radiation dose. CBCT technology utilizes a cone beam-shaped source and a two- dimensional detector to provide multidimensional accurate images for diagnosis and treatment planning. CBCT helps in localizing impacted teeth, identifying and quantifying asymmetry, visualizing airway abnormalities, evaluating placement sites for temporary skeletal anchorage devices, viewing condylar position and temporomandibular joint
