What it does

Cone-beam computed tomography (CBCT) uses X-rays to reconstruct a 3D view of teeth and jaws. It can help answer selected questions in implant planning, root canal care and oral surgery.

What usually happens

The sequence and number of visits depend on the individual case.

  1. Identify the question

    The dentist decides whether existing records or lower-dose imaging can answer the clinical question.

  2. Select the scan

    The scan area and exposure are chosen for the information needed.

  3. Capture the images

    The unit rotates around the head while you remain still.

  4. Interpret the result

    A qualified clinician reviews the scan and explains findings relevant to your care.

Options to discuss

Conventional dental X-rays

Often sufficient for routine questions.

CBCT

Adds three-dimensional detail when justified.

Optical scan

Records surfaces using light; it is not a replacement for diagnostic X-rays.

Benefits, limits & trade-offs

CBCT generally exposes patients to more radiation than conventional dental X-rays. It should be justified by a clinical need, not offered automatically because an office has the equipment.
