Conebeam computed tomography (CBCT): the new vista in oral and maxillofacial imaging.

Cone beam computed tomography (CBCT) has the potential to reduce the size and cost of CT scanners. This emerging technology produces images with isotropic sub-millimeter spatial resolution with high diagnostic quality, short scanning times of about 10-30 seconds, and radiation dosages of up to 15 times lower than those of conventional CT scans. It is ideally suited for dedicated dentomaxillofacial CT scanning. This technology provides dental practitioners with complete solution for performing specific diagnostic and clinical tasks, including implant planning, temporomandibular joint evaluation, facial fractures, dentoalveolar surgery, orthognathic surgery and periodontal surgery. CBCT is capable of providing a 3-dimensional representation of the maxillofacial hard tissues with minimal distortion. The objective of this article is to highlight the clinical applications of CBCT to oral and maxillofacial surgeons and other dental specialists in Nigeria.
