A Review on Cone Beam Computed Tomography in Orthodontics
Cone Beam Computed Tomography (CBCT) is a vital source of three-dimensional (3D) imaging analysis in clinical orthodontics. CBCT can supply more reliable information as compared to conventional two dimensional radiographs due to the advancement in the technology, reconstruction algorithms and viewing software for CBCT. CBCT is used widely for evaluation of impacted teeth. CBCT can allow to localize such impactions accurately and also to evaluate root resorption of teeth. The three dimensional nature of CBCT allows the volumetric assessment of airway structures. In addition, it enables the visualization of abnormalities of temporomandibular joint (TMJ), analysis of malocclusion, identifying the ideal bone insertion sites for mini-screws in the palate, mandibular ramus, alveolar bone, and also planning for orthognathic surgery. While recording CBCT, the justification, risks, and benefits of CBCT should be kept in mind. This review article describes the advantages, disadvantages, and utility of CBCT in orthodontics.
