How is 3-D imaging (CBCT) changing dentistry?

How is 3-D imaging (CBCT) changing dentistry?  

3-Dimensional Imaging is revolutionizing dentistry.  It is improving diagnosis and treatment in oral surgery, implant dentistry, orthodontics, and endondontics.  Computed Tomography (CT) is not new, but with the development of CBCT units now available, these images can be produced with significantly less radiation exposure (50-100X) compared to medical CT, shorter scan times (10-15 seconds in the office), and lower cost.

The CBCT provides me with a road map of sorts to plan surgical treatment.  With the ability to identify vital anatomic structures such as nerves and blood vessels, I am able to plan the best possible treatment while decreasing the risk of complications. 

 This is an excerpt from a QA that I did with a local magazine.  I have had the opportunity over the last 4 years to incorporate CBCT and 3-Dimensional imaging into my practice.  I have to say that this has completely changed my practice with regards to how I practice.

The images allow me to see things that were only available with tomograms or a medical CT.  Medical CT’s are great, but are limited by very high cost, limited availability, and large radiation exposure to the patient.

The CBCT unit allows me to bring this to the office.  The software programs available now, also allow for 3-D reconstructions that are difficult to obtain and manipulate with a medical CT.  We have an Ewoo Master Superior large field of view CBCT in our office.  This was the third unit of its kind in the United States.

We are seeing a shift in implant dentistry as CBCT is incorporated.  It is rapidly becoming the standard of care in implant dentistry.  This is due in part to the ability to identify potential problems due to bone volume, or the location of the maxillary sinus or inferior alveolar nerve.  With the ability to take direct measurements off of CBCT images, this far exceeds what can be done with panoramic x-rays or periapical films.

Before you have a dental implant placed, you should ask your surgeon or dentist to have a CBCT.  The benefit of the scan will far exceed the cost.
