3D imaging is 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.

More recently however, dentists have begun to rely on 3D imaging techniques to provide them with a detailed view of the mouth and skull.  The advantage that 3D imaging holds over regular dental x-rays is that bone structure, bone density, tissues, and nerves can be viewed clearly.

3D imaging can be completed in less than half a minute.  This means that far less radiation enters the body than if a regular set of bitewing X-rays were taken.  The main use for 3D imaging is as an aid to plan dental implant treatment and other oral surgery.

Dental implants are the most sophisticated replacement for missing teeth, but have historically proven to be time-consuming to place. 3D imaging vastly reduce the time it takes to place implants. It is thought that in the near future implants will be placed in a single visit because of this unique type of imaging.

How is 3D imaging scans used?

3D images are advantageous because they allow Dr. Bush and the staff to magnify specific areas of the face.  In addition, we can easily view cross-sectional “slices” of the jaw, which makes planning treatment easier and faster.

Here are some of the main ways in which 3D imaging is 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 is 3D imaging performed?

3D images are quick and simple to perform.  A Cone Beam Imaging System is at the heart of the 3D imager.  During the scan, the patient stands as the machine circles their head.  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 dentist is able to zoom in on specific areas and view them from alternate angles.
