Cone Beam CT (CBCT) Imaging

Dentistry has witnessed tremendous advances in all its branches over the past decade. With these advances, the need for precise diagnostic tools, specially imaging methods, has become mandatory. From the simple 2-D X-rays, advanced imaging techniques like, cone beam computed tomography (CBCT) have found a place in modern dentistry. Changing from analogue to digital radiography has not only made the process simpler and faster but also made image storage, manipulation (brightness/contrast, image cropping, etc.) and retrieval easier. Three-dimensional imaging has made the complex head and facial structures more accessible for investigation.

Types of scans

2D scans

  • OPG (orthopanthograph)
  • Lateral Ceph 
  • Sinus view

3D scans for dental 

  • CBCT of Upper jaw
  • CBCT of Lower jaw
  • CBCT of single tooth or section of jaw
  • CBCT of TMJ ( jaw joints) 

3D scans for ENT 

  • Sinus view
  • Middle ear( internal auditory meatus) 
  • Airway analysis 

Why we need these types of scans

These images are vital for accurate treatment planning for patients undergoing orthodontic (braces), implant, root canal treatment, surgical removal of wisdom teeth and other facial surgeries. In fact, these images guide the Dentist enabling execution of a treatment plan with confidence & accuracy, thus, improving quality of treatment & minimizing probability of failure.

In implant dentistry the quality and quantity of the bone present can be assessed in 3 dimensions. The software will allow for simulation of the exact type of implant length and width to be placed. This allows accurate planning of the patients’ treatment. 

Position of impacted wisdom teeth can assessed along with any vital structures (nerves) that it may affect. The radiation dose compared to a normal CT is very low. Certain CBCT outputs are less than 1/10th of a normal CT.

The overall benefit to the clinician with this additional information is very high. This translates to a more predictable and successful outcome for the patient
