Buying a CBCT is one of the biggest equipment investments you’ll make, so getting demos of any units you're considering is a wise investment of time (like test driving a car). In each demo, you'll have the opportunity to learn about the unit and the manufacturer, plus it's your chance to understand how the CBCT will fit with your clinical workflow and long-term practice plans. Make the most of your demo time with this checklist of questions you should get answered for each unit you're considering.
What fields of view (FOVs) are available, and which procedures are they best for?
Implants, endo, ortho, and airway cases all require different scan sizes. Choose a unit that covers both your current needs and potential future growth. In some cases, you may be able to purchase an upgradeable CBCT, allowing you to start at a smaller (and more affordable) FOV, while giving you the option to upgrade in the future based on practice growth. Some units have a flexible FOV, providing set FOVs while allowing you flexibility to adjust within a range.
What voxel sizes does this CBCT system support at different fields of view, and how does that affect suitability for my planned usage?
Voxel size (resolution) determines how finely a CBCT captures anatomy. Endodontic cases may require ultra-high resolution (≤100 μm voxels), while implant planning typically balances detail with coverage (125–200 μm). Orthodontic and airway evaluations use larger FOVs and therefore larger voxels (200–400 μm), which are sufficient for skeletal landmarks. Note that the sharpest voxel sizes are generally only available at the smallest FOVs, and finer resolution comes with higher dose and noise.
How is radiation dose managed. Are low-dose or pediatric modes available?
Lower dose protocols protect patients and can improve patient willingness to have a scan (which can lead to improved case acceptance).
How fast is the scan, and does it reduce motion artifacts?
Quicker scans typically mean sharper images, while the imaging algorithm can compensate for patient motion that does occur.
What processing is done to the image and when?
Is any metal artifact reduction, motion reduction, or other processing applied during image acquisition, or is it done post image acquisition? Is there an option to "turn off' any processing to see the original captured image? The ability to see a pre-processed image may allow additional analysis of clinical findings.
Does it take a true pano or a reconstructed pano?
If you rely on panoramic imaging, make sure it’s not an afterthought.
Can the unit generate an FMX, and how does the quality compare to intraoral X-rays?
Will this be a suitable replacement for individuals who can't tolerate intraoral sensors?
Does it support facial scanning or photo overlays?
These tools improve case presentation and help patients visualize outcomes by overlaying their actual images over the 3D scan.
What size room is required for installation?
Check whether you’ll need renovations or shielding upgrades, especially if the room hasn't already been used for imaging.
How large is the gantry (opening)? Will larger patients fit comfortably? Will it support both standing and sitting patient positioning?
Comfort and accessibility matter for patient experience and for your ability to capture scans for all patients that you'd like to.
What patient education features are built in?
Some manufacturers include patient education features and content in their software, which can assist you when educating patients about the pros and cons of different treatment options (for example, the difference between a bridge and an implant).
What software is included, and what type of computer is required?
Does it run on a standard PC or demand a high-end graphics workstation? How many workstations can have the software installed, or use it simultaneously? Will I be able to view scans on any operatory computer, or just specific ones?
Is it compatible with my practice management and imaging systems?
Integration saves staff time and reduces duplicate work.
Does it connect with third-party planning software (such as Blue Sky or Dolphin)?
Compatibility with tools you already use can prevent expensive software switches later.
What implant libraries are included?
An up-to-date library is critical for accurate implant planning.
How easy is it to export scans? Will anyone I share it with need additional software to view the scans?
Smooth sharing with labs and referrals avoids bottlenecks in patient care.
What training is provided, and is refresher or new-staff training available?
Understand what the initial training approach looks like. Do you get multiple sessions over time, including with real patients? Is training included when you have new staff start, or will you need to pay for additional training? Is it available for the life of the unit, or only while it's in warranty?
What warranty coverage is included (parts and service)?
Repairs can cost thousands. Get clarity on what’s included and for how long.
Are extended warranties available?
How long can you extend the warranty, and does it cover the full unit?
What is the average response time for service calls?
Downtime can mean lost production. Make sure you understand how quickly you could get replacement parts and service if an issue does occur.
What remote support options are available? What percentage of issues are resolved remotely vs requiring an in-person service call?
Phone or remote login support can fix issues faster than waiting for a tech.
Are software updates included or do they require a subscription?
Updates keep your system current, but subscription fees can add significantly to long-term costs. If software updates are included, find out if it's for the life of the unit, or only during the warranty period.
Are there any recurring costs or additional fees I should plan for?
Make sure you won't be surprised about other costs that will be required to make full use of the unit.
