CBCT has now become a standard of care in the evaluation of dental implant sites. Many manufacturers of CBCT machines claim to offer low-dose protocols which exposes the patients to a radiation dose that equals (or is less) than a panoramic image allowing to view the future implant sites in 3D and giving more information in regards to better planning and patient outcome. This presentation will show clinical cases, will compare diagnostic potential between 2D and 3D imaging, will discuss the importance of selecting the best radiographic examination to use for best decision and result in the dental implant practice. Evidence-based literature will be used and dosimetry comparison will be assessed.


Learning Objectives

At completion of this presentation, participants should be able to:

  1. Understand the power of 3D imaging in the implant planning process
  2. Recognize the information you may gain with a conebeam CT scan
  3. Discuss incidental findings in the volume scanned and area of interest and what to do next
  4. Discuss the effect of radiation and the dose for different imaging modalities used in dentistry including the use of different CBCT field of views, comparing with other sources of radiation such as cosmic and background radiation
