CBCT scanners are a variation on traditional CT scans (also called CAT scans). A CBCT scanner creates a three-dimensional radiograph (x-ray) image of an area of the body. In dentistry, they are used to create images of the oral and maxillofacial region, including dental and bone structures, airways, nerve paths, and soft tissues.

Compared to conventional dental x-rays, CBCT scans offer higher image quality and provide a far greater level of detail for dentists. Viewing the mouth in three dimensions also allows a dentist to visualize depths and volumes of the tissue more accurately, which can be a significant benefit in treatment planning.
