Also
known as dental cone beam computed tomography, cone beam scans are smaller
versions of CT scans used exclusively in dentistry. A cone beam scanner is a
special type of x-ray machine that can provide a clear and total view of the
patient’s face, mouth, and jaws.
Unlike
the traditional CT scan used in virtually every hospital nowadays, cone beam
scanning captures slices of the face and both jaws in just one quick scan rather
than taking separate scans one layer at a time. Thanks to this, there’s no
overlap of slices and an extremely detailed and accurate picture of the
patient’s mouth and jaws is made possible. Once the images are taken, they are
sent to a computer to create a precise 3-D model of the patient’s mouth, jaws,
and face that can be manipulated from all angles on a computer monitor.
Cone
beam scans are commonly used for planning the treatment of several dental issues
like surgical planning for impacted teeth, accurate placement of dental implants,
evaluations of the jaw, sinuses, nerve canals, and nasal cavity, determining bone
structure and tooth orientation, as well as an array of other procedures.
Furthermore,
with the new improvements to the technology, there’s a significantly smaller chance
of radiation overexposure, thus making cone beam scans safer as opposed to
traditional x-rays. They’re also much faster and cheaper than common CT scans
since they can pump out results in a matter of minutes.
