Dental 3D Imaging
3D imaging is an incredible diagnostic tool, allowing us to get your diagnosis right the first time. It also allows Dr. Dunson to thoroughly plan oral surgeries. To better explain what Cone Beam CT ( CBCT ) is, we should first explain regular CT.
Computed tomography (CT) imaging, also referred to as a computed axial tomography (CAT) scan, involves the use of rotating x-ray equipment, combined with a digital computer, to obtain images of the body. Using CT imaging, cross-sectional images of body organs and tissues can be produced and provide helpful information to dentists and physicians. Though there are many other imaging techniques, CT imaging has the unique ability to offer clear images of different types of tissue. It can provide views of soft tissue, bone, muscle, and blood vessels, without sacrificing clarity. Other imaging techniques are much more limited in the types of images they can provide.
To understand the difference between CT imaging and other techniques, consider an x-ray of the head. Using basic x-ray techniques, the bone structures of the skull can be viewed. With magnetic resonance imaging (MRI), blood vessels and soft tissue can be viewed, but clear, detailed images of bony structures cannot be obtained. On the other hand, x-ray angiography can provide a look at the blood vessels of the head, but not soft tissue. CT imaging of the head can provide clear images not only of soft tissue, but also of bones and blood vessels.
CT imaging is commonly used for diagnostic purposes. In fact, it is a chief imaging method used in diagnosing a variety of cancers, including those affecting the lungs, pancreas, and liver. Using this technology, not only can physicians confirm that tumors exist, but they can also pinpoint their locations, accurately measure the size of tumors, and determine whether or not they’ve spread to neighboring tissues.
In addition to the diagnosis of certain cancers, CT imaging is used for planning and administering radiation cancer treatments, as well as for planning certain types of surgeries. It is useful for guiding biopsies and a range of other procedures categorized as minimally invasive. Thanks to its ability to provide clear images of bone, muscle, and blood vessels, CT imaging is a valuable tool for the diagnosis and treatment of musculoskeletal disorders and injuries. It is often used to measure bone mineral density and to detect injuries to internal organs. CT imaging is even used for the diagnosis and treatment of certain vascular diseases that, undetected and untreated, have the potential to cause renal failure, stroke, or death.

How does the CT scan help Dentists and Physicians?
It allows them to:
-Visualize internal anatomy that can not be diagnosed externally
-Plan treatment and surgery prepare necessary aids
-Analyze the position and orientation of critical structures, like nerves, teeth roots, previous implants, the sinus and nose
Is it painful?
No, the CBCT scan process is completely painless.
Is it handicap-accessible?
The iCAT scanner from Imaging Sciences International is handicap Accessible
What are the Cone Beam scanners used for?
-Implant planning (learn more about implants)
-Orthodontic planning & implant anchorage
-Airway study (sleep apnea)
Why a CBCT scanner rather than a regular Medical CT scanner?
-X-Ray Radiation exposure to the patient is up 10 times less than a regular CT scanner.
-Much faster scan time. Scan on a CBCT takes between 10-40 sec, while on a regular CT scanner it takes a few minutes.
-Cheaper, average price of a CBCT scan could be up to 50% less than a regular MDCT scan.
What are the benefits versus risks?
-Unlike regular x-rays CT scans can discriminate between many types of tissue including bone, teeth, nerves and soft tissue.
-CT scans are noninvasive, and can eliminate the need for exploratory surgery in some cases.
-CT can identify the effects of conditions such as infection and tumors.
-A cost-effective tool for imaging a wide range of clinical problems.
As with all imaging modalities that use ionizing radiation, the use of CBCT does involve a consideration of risk to the patient. However, it has the benefit of providing useful information needed to assist in making a diagnosis and/or in facilitating treatment. When any dentist refers you for an x-ray examination, he or she has made the determination that the benefit outweighs the risk. Of course, it is ultimately up to you to decide whether to undergo the examination. Bear in mind that the risk of most x-ray examinations are much less than other risks we commonly accept in daily life.
