Cone Beam Computed Tomography and its applications in Dentistry

Document from the year 2022 in the subject Medicine - Dentistry, grade: 1, , course: Masters of Dental Surgery in Oral Medicine and Radiology, language: English, abstract: Cone-beam CT is almost certainly going to revolutionize dental radiology and impact on almost all aspects of dental practice. CBCT is an emerging technical advancement in CT imaging that uses cone beam acquisition geometry to provide relatively low-dose imaging with high isotropic spatial resolution acquired with a single gantry revolution. Efficient use of the x-ray beam in CBCT imaging produces a relatively low x-ray tube power requirement, which, along with flat panel detection and limited anatomic coverage, has facilitated the production of compact CBCT scanners suitable for use in an office-based setting. The development and rapid commercialization of CBCT technology dedicated for use in the maxillofacial region will undoubtedly increase both general and specialist practitioner access to this imaging modality. CBCT is capable of providing accurate, sub-millimetre resolution images in formats enabling 3D visualization of the complexity of the maxillofacial region. Increasing availability of this technology provides the practitioner with a modality that is extending maxillofacial imaging from diagnosis to image guidance of operative and surgical procedures.
