About Cone Beam Technology

Category: 3D Cone Beam (CBCT)

Our goal is to provide you with the best, most accurate, and thorough diagnosis possible. Fortunately, recent technological breakthroughs have allowed us to make major advances in our ability to achieve that goal. Cone Beam Computed Tomography (CBCT) (“dental cone beam” or “cone beam”) is a new technology similar to CAT scans in that it will give us a 360 degree 3 dimensional view of the area we are examining. Previously, we were limited by dental X-rays, even digital dental X-rays, to a two dimensional picture of a three dimensional problem.

There were many things we could not see because X-rays did not have the resolution to show them. Despite our best efforts, we were forced to infer, project, surmise, calculate, and interpret. Often, we could only give our best educated guess based on what we could see on the X-ray. Additionally, X-rays were often just not sensitive enough to show very small or beginning problems. That has all changed significantly with the advent of the dental cone beam technology. With its extremely high resolution and exceptionally low radiation, it has literally changed our world with respect to what we can now see.

Cone Beam 3D imaging offers a large volume of information and subtle details that simply cannot be obtained by any two dimensional X-ray, whether intraoral or panoramic. One 3D scan will allow us to examine the region of interest at a high resolution from many different perspectives. Clinical studies support this technology’s improved diagnostic capabilities. We are very proud of cone beam 3D and feel strongly that this state-of-the-art technology will allow us to provide our patients with the very highest level of care possible today

Taking the image is as simple as sitting still. The scan will take less than 18 seconds and the images are transferred directly to a computer. A common question about 3D imaging is the amount of radiation that is emitted in obtaining this type of image. In an effort to provide the best care and lowest radiation dose possible, we selected the CS9000 3D Extraoral Imaging System by Carestream. This machine offers extremely low radiation exposure.

We tend to be on the conservative side, so only if it is necessary or if you have a referral for a CBCT, will we take a cone beam image.

Features and Benefits

Faster and safer Since CBCT captures images in a single rotation, scan time is quicker than that of traditional spiral CT systems. Plus, since radiation doses are relative to the size of the FOV selected, practitioners can reduce the amount of radiation to which patients are exposed while focusing on particular regions of interest.

Greater accuracy Comprised of 3D cuboid structures known as voxels, the volumetric data set sent to the imaging software allows dentists to render 3D images that can be manipulated to show certain tissues, view different angles, and display varying thicknesses and depths.

Versatility Not to be limited by their own advancements, CBCT systems can be used for traditional forms of radiography, including cephalometric, panoramic and 2D imaging. This not only provides dental practitioners with additional diagnostic tools, but also makes the transition to 3D imaging easier for dental assistants and other staff.

Greater patient comfort and improved education On top of the peace of mind provided by lower radiation dosages, CBCT systems are manufactured specifically with increased patient comfort in mind. This means less restrictive positioning and more open environments with plenty of space. Also, the ability to provide patients with full 3D renderings of their condition illustrates problems in a visual manner, allowing them to play a larger, more collaborative role in their own treatment.

Cone-beam computerized tomography (CBCT) is quickly becoming the defacto maxillofacial imaging technology for diagnosis, surgical and implant-treatment planning. The key difference between CBCT and its predecessors is in the name: traditional CT scans record data with a helical, fan-shaped beam that transmits images to detectors placed in an arc around the patient, while CBCT systems employ a cone-shaped beam with a larger, adjustable field of view (FOV). And while the traditional CT captures images in thin slices that require several rotations around the patient to yield a full picture, CBCT covers the entire volume of diverse areas of interest in a single rotation
