Dental Cone Beam CT Scan

Dental Cone Beam Computed Tomography is a particular type of x-ray machine used in situations where regular dental or facial x-rays are not sufficient.  This particular type of CT scanner uses a special type of technology to produce three dimensional images of dental structures, soft tissues, nerve paths and bone in the craniofacial region in a single scan. Images generated with cone beam CT help to plan the treatment more precisely.

Cone Beam CT and the conventional CT are not the same thing though CBCT may produce similar images like one produced by the regular CT. CBCT provides detailed images of the bone. It is preferred over the regular CT as it helps to evaluate diseases of the jaw, dentition, bony structures of the face, nasal cavity and sinuses. It does not provide the full diagnostic information available with conventional CT, particularly in evaluation of soft tissue structures such as muscles, lymph nodes, glands and nerves. Cone Beam CT however has the advantage of lower radiation exposure compared to conventional CT.

How does the CBCT work?

CBCT was developed with an intention of producing similar type of images as CT at much smaller expense and detailed, high quality images. In the procedure of 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. In a single rotation, the detector can generate anywhere between 150 to 200 high resolution images, that can provide your dentist or oral surgeon with valuable information about your oral and craniofacial health.

How to prepare for CBCT Dental procedure?

CBCT scans do not require much preparation except you must wear comfortable, loose fitting clothes to your examination or else you will asked to change into a gown. Metal objects such as jewellery, spectacles, hairpins or dentures or hearing aids which might affect the image of the scan, must be removed prior the examination. Women will be asked to remove bras containing metal underwire. Piercings are also suggested to be removed if possible.


In dentistry, the procedure is generally used for orthodontic needs but it may be also used for surgical planning for impacted teeth, accurate placement of dental implants, evaluation of the jaw, detecting, measuring and treating jaw tumors and determining bone structure and tooth orientation.
