Beverly Hills Maxillofacial Surgery - Cranio-Maxillofacial Surgery Institute - Cone Bean CAT Scans

Physicians have relied on computerized axial tomography scans (CAT), for many years.  CAT scans are an X-ray procedure that uses many different X-ray images with the help of computers to generate cross-sectional or even 3D views of internal organs and structures within the body.  A knee replacement surgery, for example, would never be performed without first examining 3D imaging. The big issue with CAT scan is the amount of ionazing radiation dilivered to the patients that have all concerned

More recently however, surgeons and dentists have begun to rely on 3D imaging techniques and cone beam CAT scans to provide them with a detailed view of the facial skeletal structure without the high dose of radiation.  Another advantage that a cone beam CAT scan imaging holds over regular scan or x-rays is that the high quality of the image.

Cone beam CAT scans can be completed in less than half a minute.  This means that far less radiation enters the body than if a regular set of scan.  The main use for cone beam CAT scans is as an aid to plan for surgery.

How are cone beam CAT scans used?

Cone beam CAT scans are advantageous because they allow the surgeon to magnify specific areas of the face.  In addition, the surgeon can easily view cross-sectional “slices” of the facial skeleton, which makes planning treatment easier and faster.

Here are some of the main ways in which i-CAT® scans are used in dentistry:

  • Assess the quality of the jawbone where the implant will be placed.
  • Determine where nerves are located.
  • Diagnose tumors and disease in the early stages.
  • Measure the density of the jawbone where the implant will be placed.
  • Pinpoint the most effective placement for implants, including the angle of best fit.
  • Plan the complete surgical procedure in advance, from start to finish.
  • Precisely decide on the appropriate size and type of implants.
  • View exact orientation and position of each tooth.
  • View impacted teeth.

                                       

How are cone beam CAT scans performed?

Cone beam CAT scans are quick and simple to perform.  A Cone Beam Imaging System is at the heart of the CAT scanner.  During the scan, the patient sits or stands stationary on a designated area.  The cone beams are used to take literally hundreds of pictures of the face.  These pictures are used to compile an exact 3D image of the inner mechanisms of the face and jaw.  The surgeon is able to zoom in on specific areas and view them from alternate angles.

Previous patients report the cone beam CAT  scanner is comfortable because they remain in a sitting or standing position at all times.  Additionally, the scanner provides an open environment, meaning that claustrophobic feelings are eliminated.  The cone beam CAT scan is an incredible tool that is minimizing the cost of surgical treatment, reducing treatment time and enhancing the end results of facial skeletal surgery.

In our practice we currently use the Kodak 9500 cone beam CAT scan. If you have questions or concerns about cone beam CAT scans or 3D imaging, please contact our office.
