Applications of cone beam computed tomography for a prosthodontist

open access: yesThe Journal of Indian Prosthodontic Society, 2016
Cone beam computed tomography (CBCT) is a medical imaging technique of X-ray computed tomography where the X-rays are divergent, forming a cone. CBCT systems have been designed for imaging hard tissues of the maxillofacial region. The increasing availability of this technology provides the dental clinician with an imaging modality capable of providing ...
