Your dentist or specialist has referred you for a CBCT scan a 3D imaging technique that gives a far more detailed view than a traditional X-ray. Here is what it involves and why it is used.

CBCT stands for Cone Beam Computed Tomography. It is a type of CT scan specifically designed for the head and neck area, including your teeth, jaws and surrounding structures.

A traditional dental X-ray produces a flat, two-dimensional image. A CBCT scan produces a three-dimensional image that can be viewed from any angle.

Instead of showing you a single plane, a CBCT scan lets your dentist look at your teeth and jawbone in depth. They can slice through the image, zoom in and examine structures from multiple perspectives.

This level of detail is particularly valuable for complex diagnoses and treatment planning. It is a bit like the difference between looking at a map and being able to fly over the actual landscape.

CBCT images show your teeth, jawbone, nerve pathways and soft tissues in three dimensions. Your dentist can see the exact shape and density of your bone crucial information for planning dental implants.

It reveals the precise location of nerves, blood vessels and sinuses, reducing the risk of complications during surgery. It is also used for complex root canal treatments, detecting fractures that do not show on regular X-rays, and planning orthognathic (jaw) surgery.

The CBCT scanner looks similar to a panoramic X-ray machine. You will stand or sit with your chin on a rest and remain very still for about 20 to 40 seconds while the machine rotates around your head.

Unlike some medical CT scans, dental CBCT does not require you to go inside a tunnel. The experience is open and relatively comfortable.

The radiation dose from a dental CBCT scan is higher than a traditional dental X-ray but significantly lower than a medical CT scan of the same area. Your dentist or specialist will only recommend a CBCT scan when the diagnostic benefit clearly justifies the exposure.

Not every patient needs a CBCT scan. It is used selectively for complex cases where 2D X-rays simply do not provide enough information for accurate diagnosis and treatment planning.
