CBCT Technology

Skull icatimplant 1

The dental CBCT imaging method allows dentists to obtain vital three-dimensional information without exposing patients to high levels of radiation that the patient would receive from medical CT scans.

The following compares the absorbed radiation emitted from each x-ray modality or activity:

  • Full mouth dental periapical films- 150 microseverts
  • Panorex- 10-15 microseverts
  • A round trip flight from NY to LA is 40 microseverts (flight crews and pilots get 2000-4000 microseverts/year)
  • Medical CT falls in the range of 2000-5000µSv with a head/sinus CT usually around 2200 µSv
  • Our brand new ICAT FLX machine can take 3D scans with doses as low as 4µSv.  That is significantly less than any other machine out there.

Before a practitioner performs surgery, he/she should be equipped with up-to-date knowledge regarding the possible conditions located under the soft tissue within the oral cavity.

In the past, doctors would have to send you to the hospital or imaging center for the scan.  To make it more convenient for our patients we have this technology in our office.

Three dimensional data generated by cone beam computed tomography(CBCT) technology offers a ‘surgical view’ or slices of the entire field of view. Cone beam scans assist with determining bone structure, nerves, arteries and veins,  and pathology. The knowledge obtained from capturing 3D scans has the ability to influence the effectiveness and efficiency of dental treatment. During a CBCT scan, the scanner rotates around the patient’s head, obtaining nearly 600 distinct images. The scanning software collects the data and reconstructs it, producing what is termed a digital volume composed of three dimensional voxels of anatomical data that can then be manipulated and visualized with specialized software.

 Why Dr. Tran would ask for a scan:

Dental Implants

  • Location of anatomic structures: mandibular canal, submandibular fossa, incisive canal, maxillary sinus
  • Size and shape of ridge, quantity and quality of bone
  • Number, orientation of implants
  • Need for bone graft, sinus lift
  • Use of implant planning

What are the advantages of CBCT?

  • Lower radiation dose than  2D panoramic radiographs
  • Thyroid shield can be used in many cases
  • Comfortable for patients
  • Scan time is only 4 to 8 seconds
  • Images are available almost immediately on screen
