Cone Beam 3D Imaging (CBCT)

Cone Beam Computed Tomography, commonly called CBCT, is an advanced form of dental imaging that creates detailed three-dimensional views of the teeth, jawbones, and surrounding anatomical structures.

Unlike traditional 2D dental X-rays, which provide a flat image, CBCT allows our team to examine dental structures from multiple angles and better understand their spatial relationships.

This additional information can be especially valuable when evaluating complex dental conditions, planning treatment, and assessing areas that may not be fully visible on conventional dental X-rays.

What Is CBCT?

A CBCT scan uses a cone-shaped X-ray beam to capture multiple images as it rotates around the patient. Specialized computer software then combines these images to create a three-dimensional representation of the area being examined.

CBCT can provide detailed information about:

• Teeth and tooth roots

• Jawbone structure

• Nerve pathways

• Sinuses

• The temporomandibular region

• Implant sites

• Airway anatomy

• Areas of bone loss or other abnormalities

Because CBCT provides three-dimensional information, it can help our team evaluate structures that may be difficult to fully understand using traditional 2D X-rays alone.

Cavitations & Previous Extraction Sites

CBCT imaging can be particularly useful when evaluating areas of the jaw where teeth have previously been extracted.

A previous extraction site may show changes in bone density, shape, or healing that warrant further evaluation. A CBCT scan can provide a more detailed view of the three-dimensional anatomy of these areas than a conventional dental X-ray.

Some practitioners use the term cavitation to describe an area of altered or incomplete bone healing at a previous extraction site. The significance and causes of these findings can vary, so they should be evaluated on an individual basis.

When a patient has concerns about a previous extraction site, CBCT imaging can provide additional information that may help determine whether further evaluation or treatment is appropriate.

Superior 3D Image Quality

One of the primary advantages of CBCT is the amount of anatomical detail it can provide.

Dr. Allen can evaluate the relationship between teeth, roots, bone, nerves, sinuses, and other surrounding structures in three dimensions. This can be particularly helpful when diagnosing or planning treatment for more complex conditions.

CBCT may assist in evaluating findings such as:

• Cysts or other abnormal areas

• Bone loss

• Bone infections or inflammation

• Impacted teeth

• Root fractures or other dental abnormalities

• Complex root anatomy

• Sinus-related dental concerns

• Jawbone abnormalities

• Extraction site cavitations

CBCT is not necessary for every dental examination. It is typically used when the additional three-dimensional information can contribute meaningful information to diagnosis or treatment planning.

Airway Assessment

CBCT can also provide three-dimensional information about the upper airway.

When clinically appropriate, this information may be useful when evaluating the anatomy of the airway and its relationship to surrounding structures.

A CBCT airway assessment may allow us to examine:

• Airway size and shape

• Areas where the airway may appear narrowed

• Surrounding anatomical structures

• The relationship between the jaws, tongue space, and airway

Better Dental Implant Planning

CBCT has become an important tool for planning dental implant treatment.

Before placing an implant, it is important to understand the available bone, the location of nearby anatomical structures, and the relationship between the proposed implant location and surrounding tissues.

The three-dimensional information from CBCT can help with:

• Evaluating available bone

• Identifying important anatomical structures

• Assessing the location of nerves

• Evaluating the relationship to the maxillary sinus

• Determining appropriate implant positioning

• Planning bone grafting when necessary

• Creating computer-guided surgical plans

In appropriate cases, CBCT data can also be used to create a surgical guide that helps transfer the planned implant position to the clinical procedure.

This detailed planning can improve surgical precision and help reduce avoidable risks associated with implant placement.

A More Complete View

Traditional dental X-rays remain an important part of routine dental care, but they cannot show every aspect of a three-dimensional anatomical structure.

CBCT gives us another level of information when a more detailed view is warranted.

Our goal is not to use advanced imaging simply because it is available. Instead, we use CBCT when the additional information can help us better understand a patient's individual anatomy, diagnose a condition, or plan treatment.

CBCT in Omaha

If you are interested in advanced dental imaging or have questions about a previous extraction site, dental implant treatment, airway anatomy, or another complex dental concern, CBCT may provide valuable additional information.

Dr. Allen can determine whether three-dimensional imaging is appropriate for your situation and explain what the images show and how that information relates to your treatment options.
