What is CBCT scan?
CBCT stands for cone beam computerized tomography and is an important Xray technique helping in diagnosis and treatment planning in dentistry in various situations. Sometimes regular 2-dimensional X-rays are not enough to give minute details of the area concerned and, in such cases, CBCT is very useful. It is a 3 dimensional, giving more detailed information, using less radiation and produces high quality images of bone and soft tissues.
What is the principle of CBCT scanning?
This advanced scan uses a rotating device attached to an X-ray source and detector. From the X-ray source, radiation in the form a cone is directed to middle of target area and from there onto the detector. Multiple images are obtained in one complete scan and these raw images are reconstructed on the computer to an accurate scan image.
What are the uses of CBCT scan in dentistry?
  • Surgical planning for deeply impacted teeth.
  • Assessment of TMJ disorders.
  • Dental implant placement planning in terms of bone density, bone quality, distance from nerve canals and sinuses.
  • To detect pathologies of sinuses, nasal cavity or jaw tumors.
  • Evaluation of large areas of infection in the jaws.
What are the benefits of CBCT scan?
  • Images are of high quality and accuracy
  • Lower radiation exposure
  • Less expensive than conventional CT
  • Wide angle view of target area, giving more complete & useful information
  • Non-invasive and fast imaging technique
