Which Field Of View Is Right For You?

If you are wrestling with the idea of adding a new 3D imaging system to your practice, there are a few questions you should ask yourself:

  • What do I want to do with the information that the new system will provide?
  • Am I interested in return on investment (ROI)? (Of course you are, but is there more to it than that—like broadening your skills as a clinician?)
  • Am I expanding the capabilities of my practice in the future?

How you answer these questions can help you determine which field of view (FOV) is right for you and which imaging system best fits your needs.

What Do You Want to Do?
Is it endodontics? Implants? Airway analysis? Orthodontics? The following table can help you determine what to look for in an imaging solution.

Field of View
Small FOV
(5cm x 5cm)
Medium FOV
(8cm x 9cm)
Large FOV
(up to 17 cm)
Goal
Endodontics
View one or two teeth at a time
X X
Implantology
Scan single and dual jaw; perform guided surgery
 

X

X
Oral surgery
Evaluate: trauma cases; TMJ disorders; airway/sleep apnea disorders
X
Periodontics
(including, but not necessarily only implants)

Orthodontics
Evaluate: ectopic and impacted teeth; third molars

Assess TMJ, skeletal symmetry X
Airway
Evaluate airway, sleep apnea

Is Your Objective ROI?
If you are considering a shift to in-house imaging, ask yourself how many times per month you refer patients out for a scan. If your average is four or more, it may make sense to invest in a cone beam computed tomography (CBCT) imaging system. In about a year or less, your system could pay for itself.* Continue reading
