CBCT (3D X-ray)

Cone Beam Computed Tomography (CBCT) is an advanced imaging technology that plays an increasingly important role in modern dentistry. Compared with standard dental X-rays—and in many cases with conventional medical CT—CBCT provides high-resolution, three-dimensional images while typically using a significantly lower radiation dose than a classic medical CT scan. This makes it possible to assess teeth, the jawbone, and nerve pathways with great precision, which is why CBCT has become an important tool in comprehensive dental diagnostics.

What is a CBCT?

Cone Beam Computed Tomography (CBCT) is a specialised 3D X-ray scan designed to capture detailed images of the teeth, jaws, and facial structures. While conventional dental X-rays show only two-dimensional views, CBCT creates accurate three-dimensional images. This allows us to see complex anatomical details—such as fine root canals, nerve pathways, or changes in the jawbone—far more clearly and in greater detail.

A CBCT works in a similar way to a CT scan, but uses a much narrower, cone-shaped X-ray beam—meaning the radiation dose is typically significantly lower than a conventional medical CT. The scan itself takes only a few seconds, and the images are captured and processed digitally straight away, without any X-ray films.

Benefits of CBCTs

• High image quality: 3D imaging allows a precise assessment of the teeth and jaw structures.

• Lower radiation exposure: Compared with conventional medical CT, CBCT typically uses a significantly lower dose—while providing high resolution within a smaller, focused scan area.

• Improved diagnostics: By clearly locating nerve pathways, cysts, or inflammatory changes, CBCT supports precise treatment planning and can increase safety during procedures.

• Time-saving: The scan takes only a few seconds, and the 3D images are available to our team straight away.

• More precise, minimally invasive planning: Detailed pre-planning can make procedures such as dental implants or wisdom tooth removal gentler, safer, and more efficient.

Use cases of CBCT

CBCT is used in many areas of dentistry, including:

• ImplantologyFully digital dental implant planning: CBCT allows us to measure bone height, width, and density and to map nerve pathways—essential for placing implants safely. With 3D imaging, implants can be planned with millimetre-level precision.

• Endodontics (root canal treatment): A CBCT can reveal complex root canal anatomy and helps detect hidden inflammation, root fractures, or canals that are difficult to locate on standard X-rays.

• Oral surgery: Before procedures such as removing impacted wisdom teeth, treating cysts, or planning jaw surgery, CBCT provides the detailed anatomical information needed for safe planning.

• TMJ assessment: For jaw joint symptoms or functional problems, CBCT can show bony changes and support a more detailed diagnosis.

What happens during a CBCT scan

1. Preparation: You’re positioned carefully to minimise movement and ensure sharp images.

2. Scanning: The CBCT unit rotates around your head for a few seconds, capturing multiple images that are then reconstructed into a 3D model.

3. Review and analysis: The 3D data is displayed on screen immediately and is assessed by your dentist (or oral surgeon, if involved).

4. Discussing the results: We explain the findings in clear terms and agree the next steps together.

Conclusion

Cone Beam Computed Tomography (CBCT) has become an important part of modern dentistry. It combines highly detailed diagnostics with a comparatively low radiation dose and allows us to plan dental and surgical procedures in a safer, more gentle way. Patients benefit from clearer explanations, more efficient treatment planning, and an overall higher level of safety.

If you’re facing a more extensive dental procedure, it’s worth speaking with our team about whether a CBCT scan would be helpful. Investing in modern diagnostics can improve planning, increase safety, and support better outcomes.
