Computerized Tomography (CBCT)

Cone Beam Computed Tomography (CBCT) is a radiographic imaging method that allows for 3D visualization of maxillofacial structures such as bones, nerves, and soft tissues. It is a variation of traditional computed tomography (CT) but uses a cone-shaped X-ray beam and a detector that rotates around the patient to capture a few hundreds of images which are then used to reconstruct a final 3D image.

Compared to standard x-rays, a dental CBCT scan is a much more detailed and effective method of capturing information about your dental health. CBCT technology also uses less radiation and requires fewer scans to see the different views and angles of the mouth. Plus, unlike traditional dental x-rays, the cone beam CT scan can show both bones and soft tissues.

CBCT advantages:

  1. High-resolution 3D images: Unlike traditional 2D dental radiographs, CBCT provides three-dimensional images, which can offer better visualization and understanding of anatomical structures.
  2. Reduced Radiation Exposure: CBCT exposes the patient to less radiation than a conventional CT scan while providing the detailed images necessary for dental evaluations.
  3. Shorter Scan Time: CBCT scans are quicker than conventional CT scans, capturing a few hundred images from a variety of angles and compiling it into a single 3D image in around 30 seconds.
  4. Applications: CBCT is used in various dental specialties, including oral surgery, orthodontics, endodontics, periodontics, and implant planning.
  5. Detailed Bone Assessment: CBCT is particularly useful in assessing bone quality and quantity, which is crucial for procedures like dental implant placement.

Use cases:

  1. Implant Planning: To determine the optimal location for implant placement, considering vital structures like nerves and sinuses.
  2. Orthodontic Assessment: For detailed cephalometric analysis and treatment planning.
  3. Evaluation of the Jaw Joints: To visualize the temporomandibular joints in cases of TMD or other joint disorders.
  4. Sinus Examination: Especially relevant for procedures that might affect the sinuses, such as upper molar extractions or sinus lifts for implants.
  5. Endodontic Evaluation: Provides a clear view of the root canals, helping in cases of complex root canal treatments.
  6. Diagnosis of Pathologies: Helps in detecting cysts, tumors, and other pathological conditions in the jaw.

FAQ

When should CBCT be performed?

It's used when 3D visualization offers a clear advantage over 2D images. Here are the scenarios when a CBCT scan may be recommended:

  1. Dental Implant Planning: Before placing dental implants, CBCT can provide a detailed view of the jawbone's quality and quantity. This is essential for determining the optimal placement and size of the implants, ensuring they don't impinge on vital structures like nerves or sinuses.
  2. Orthodontics: For complex orthodontic cases, CBCT can offer insights into the positions of teeth, especially impacted or supernumerary ones. It also aids in cephalometric analyses and treatment planning.
  3. Endodontics:In cases of complex root canal treatments, CBCT can provide a clear 3D view of the root's anatomy, revealing extra canals, root fractures, or periapical lesions that might not be evident on a standard 2D radiograph.
  4. Temporomandibular Joint (TMJ) Disorders:CBCT can visualize the TMJ in great detail, which can be beneficial when diagnosing and planning treatments for TMJ disorders.
  5. Sinus Examination: Before procedures that might impact the sinuses, like sinus lifts or upper molar extractions, CBCT can provide a detailed view of the sinus anatomy and any potential pathologies.
  6. Diagnosis of Dental and Maxillofacial Pathologies: CBCT can assist in detecting and defining the extent of cysts, tumors, and other pathological conditions in the jaws.
  7. Trauma: For patients with facial or dental trauma, CBCT can provide a comprehensive view of fractures and associated injuries.
  8. Surgical Planning: Especially for complex surgeries, like orthognathic operations or guided bone regeneration, CBCT aids in pre-surgical planning.
  9. Airway Assessment: In patients suspected of having sleep apnea or other airway obstructions, CBCT can be used to evaluate the airway's dimensions.
  10. Evaluation of Impacted Teeth: To determine the position and relation to adjacent structures, which can guide the approach for surgical extractions.

What are the limitations of a CBCT?
While CBCT offers exceptional visualization of bony structures, it might not be as detailed for soft tissues, such as muscles, lymph nodes, or glands. In such cases, other imaging modalities like MRI might be preferred.

How does the procedure look like?

The procedure is non-invasive and painless:

  • The patient is asked to remove anything that may interfere with the imaging, including metal objects, such as jewelry, eyeglasses or hearing aids.
  • The patient either sits or stands in the CBCT machine.
  • The patient must remain still during the scan to ensure image clarity. As the scanner rotates around the patient's head, it captures multiple images from various angles, which are then reconstructed into a 3D model.

Do I need to prepare for the procedure?
No special preparation is required. You will only be asked to remove any metal objects like glasses, earrings, and necklaces. If you have dental appliances or dentures, you might need to remove them as well.

When will I get my results?
Shortly after each examination we will send the results via email to you and/or to your doctor's email address listed on the referral. Additionally we can provide the results on a CD or Pendrive.

Is it safe to have a Computed Tomography during pregnancy?
Always inform your dentist or technician if you're pregnant or suspect you might be. While the radiation dose is low, it's a general practice to avoid any unnecessary exposure to it during pregnancy.

Is there an age limit for Computed Tomography?

No, there isn't an age-specific limit. Computed Tomography can be beneficial for both children and adults, depending on the medical concern.

Always consult with your doctor for specific details and any further queries related to Computerized Tomography or any other medical procedure.
