A CBCT (cone‑beam CT) scan produces high‑resolution 3D images of teeth, jaws and facial bones. It’s used for dental implant planning, endodontics (root canal anatomy), assessment of impacted teeth, TMJ evaluation, orthodontic and surgical planning, sinus and trauma evaluation, and detection of jaw pathology. It guides precise treatment where detailed bone structure and spatial relationships are essential.

Cone-beam CT (CBCT) uses a cone-shaped X-ray beam and flat-panel detector to produce high-resolution 3D images of bone, commonly for dental and maxillofacial use, with lower radiation dose but limited soft-tissue contrast. Conventional (medical) CT uses fan-shaped beams and multi-detector arrays, provides better soft-tissue detail and larger field-of-view for whole-body imaging, but typically at higher radiation exposure.

CBCT can reveal abnormal masses or bone changes and help localize lesions, but has limited soft‑tissue contrast and is not ideal for definitive tumor detection or characterization. It may suggest a lesion requiring further evaluation, but MRI or contrast‑enhanced diagnostic CT (and biopsy when indicated) are preferred for accurate tumor diagnosis, staging, and treatment planning. See a specialist if suspicious findings appear.

Yes. Cone-beam computed tomography (CBCT) acquires volumetric data by rotating a cone-shaped X‑ray beam and detector around the patient to reconstruct a true 3D image. It provides high-resolution, multiplanar views of bone and dental structures for diagnosis, treatment planning, and surgery. CBCT often delivers lower radiation than conventional CT but has limited soft-tissue contrast compared with medical CT.

A CBCT scan exposes patients to higher radiation than conventional dental X‑rays (though generally lower than full medical CT), so use is justified only when benefits outweigh risks. Other risks include image artefacts from metal restorations, incidental findings that can cause anxiety, and contraindication in pregnancy. Minimizing dose, limiting the field of view, and expert interpretation reduce potential harm.

A CBCT scan’s actual X‑ray exposure is very quick—typically 10–40 seconds—while patient positioning and setup add several minutes. In most clinics the entire appointment takes about 5–20 minutes. Larger fields of view, higher resolution settings, or special positioning needs can extend total time slightly. Image reconstruction and review by the clinician may take a few additional minutes.
