Dental CBCT
Dental CBCT (cone-beam computed tomography) is a 3D exam of the teeth, jaws, and surrounding tissues. It is widely used for implant planning and oral surgery.
How it differs from medical CT
CBCT uses a cone-shaped beam, so one rotation captures the whole jaw region. Its radiation dose is usually lower than a conventional medical CT, although it remains higher than a panoramic X-ray.
The result is a three-dimensional volume that can be viewed in multiple planes to assess root position, the inferior alveolar nerve canal, and bone density.
Clinical uses
CBCT is often used to plan dental implants, assess impacted wisdom teeth close to nerves, and evaluate jaw cysts or tumors. Orthodontists also use it for complex treatment planning.
The exam also helps evaluate the maxillary sinuses before certain upper-jaw procedures.
Things to know
Patients are asked to remove jewelry, metal objects in the head area, and removable dentures. The scan is usually brief, around one to two minutes.
Because its dose is lower than medical CT, CBCT still needs to be properly indicated. Your dentist will choose the exam according to your treatment needs.
Key points
- Used for dental implants and oral surgery planning.
- The dose is lower than a standard medical CT.
