1. Support and training
Support is the most important quality, and the easiest to overlook. True support includes onboarding, chairside training for the whole team, ongoing education, and fast help when something goes wrong in the middle of a patient visit. Ask who provides the training, whether it happens in your office or online, and how quickly support responds. A scanner your team is not confident using will end up in a drawer.
2. Software
Software drives the learning curve and the day to day experience. Look at the user interface, scanning prompts and feedback, AI features such as soft tissue filtering, and how often updates are released. Just as important is the lab connection. An open system exports standard files so you can send cases to any lab without restrictions. Ask for a live demonstration rather than relying on videos.
3. Versatility
Some scanners are built for a narrow set of indications. Confirm the scanner can handle the cases you actually see: single crowns, bridges, implant scan bodies, partials, dentures, full arch, and orthodontic records. Depth of field matters here, since a deeper scan range makes posterior and hard to reach areas easier to capture. Peer groups of dentists who already use the scanner are a good place to ask how it performs across case types.
4. Clinical proof
Every scanner images a stone model well. Scanning a live patient with saliva, soft tissue, and limited access is a different test. Ask for documentation of real clinical cases such as crowns, implants, and full arch work, and talk to dentists who use the scanner every day. Real patient results are the best way to know whether the scanner performs the way the specifications suggest.
5. Total cost of ownership
Compare cost over five years, not just the purchase price. Add any subscription, software license, or per-scan fees, then subtract what you will save on impression material, shipping, retakes, adjustments, and chair time. Scanners you own outright with no recurring fees usually come out well ahead over five years. Ask every vendor for a written five year total.
6. Warranty
One year coverage has long been the norm for dental technology. Ask how long the warranty lasts, what it covers, whether an extended warranty is available and when you have to buy it, and what happens if the scanner fails. Find out whether you will receive a loaner or a replacement unit quickly, because a scanner that is out for repair stops your digital workflow.
7. Scan quality
Image quality is what your lab cares about most. Accuracy depends on the optics, the number of cameras, calibration, and the software that processes the scan. Look at accuracy specifications, self calibration, and color realism, and ask the lab you work with to review sample scans. Clean margins and contacts in the file mean better fitting restorations and fewer remakes.
