What is a Cone Beam CT Scan?
Dental cone beam computed tomography (CBCT) is a special type of x-ray used when regular dental x-rays are not sufficient. We may use this technology to produce three dimensional 3D images of your teeth, soft tissues, nerve pathways and bone in a single scan. Images obtained with cone beam CT allow for more precise treatment planning.
CBCT is not the same as conventional CT. However, dental cone beam CT can be used to produce images that are similar to those produced by conventional CT imaging.
With cone beam CT, an x-ray beam in the shape of a cone is moved around the patient to produce a large number of images, also called views. CT scans and cone beam CT both produce high-quality images.
Dental cone beam CT was developed as a means of producing similar types of images but with a much smaller and less expensive machine that could be placed in the dentist’s office.
Cone beam CT provides detailed images of the bone and is performed to evaluate diseases of the jaw, dentition, bone structure, nasal cavity and sinuses. The cone beam CT has the advantage of lower radiation exposure compared to conventional CT.
