What is CBCT?

CBCT is a digital x-ray scanner specifically designed for scanning the head and jaws. The technology employed at EDI is called an i-CAT CBCT. The scanner rotates 360 degrees around the patient’s head in a matter of seconds. The x-ray is a low-energy, fixed anode tube, similar to those used in panoramic machines. The cone-shaped x-ray provides 360 views that can be presented in 2D image and 3D volume for advanced planning and diagnostic support. With a typical scan time of 20 seconds or less, the patient is subject to significantly less radiation than traditional Medical CT scans of the oral and maxillofacial region.

What is CBCT used for?

The i-CAT Cone Beam 3D Imaging system provides dentists and specialists complete views of all oral and maxillofacial structures, giving the dental professional the most thorough diagnostic information possible for a variety of treatment areas. This allows for more accurate treatment planning and more predictable treatment outcomes.

  • TMD Investigation – A CBCT scan provides thee-dimensional images of the condyles and surrounding structures, allowing for a complete analysis and diagnosis of bone morphology, joint space, and function. Combined with radiological reporting by our Oral and Maxillofacial Radiologist, dental professionals are given the critical information needed to evaluate and design treatment plans.

  • Impaction/Supernumerary Investigation – Three-dimensional imaging provides more accurate viewing of impacted, supernumerary, or abnormal teeth in relationship to other anatomical structures, such as roots, nasal fossa, and sinuses. Understanding the tooth’s position and its relationship to adjacent teeth and structures enhances accurate management of the treatment.

  • Medical Modeling – Medical Modeling is a procedure during which a highly accurate physical model can be made from medical imaging modalities such as CBCT. Sophisticated software is used to view and extract information to create a virtual, 3D model of a patient’s bone structure. After the virtual model is created, the digital file is then sent to a rapid prototyping machine to produce the final model in physical form. Complete models are then measured and checked for accuracy and have become a valuable tool when planning Mandibular/Maxillofacial Orthognathic Surgery, Craniofacial or TMJ Reconstruction, or for Distraction Osteogensis treatment.
  • Sinus/Upper Airway Investigation – Volumetric data obtained from a CBCT survey can be used to visualize the sinuses and the entire airway path from the nasal and oral entrances to the laryngeal spaces for:

    – Identification of anatomical borders
    – Determination of degree of infection and presence of polyps
    – Assistance in airway studies for diagnosis and treatment of obstructive sleep apnea
    – Calculation of actual volume of airway space
    – Determination of the point of airway constriction
