Intraoral scanners look like the perfect used-market item: small, light, easy to ship, and expensive new. In practice they are one of the trickiest categories to buy secondhand, because the device in the box is only useful if the manufacturer's software will run it for you, in your name, and keep running it. Some brands have formal transfer programs, some require a paid subscription to keep scanning, some have no subscription at all, and every brand eventually ends support for older models.
This guide explains how scanners work, why their used values behave so differently by brand, what to check before buying, and how to think about cost.
Key takeaways
- A used scanner's value depends first on whether the manufacturer will license and support it for a new owner. Check that before anything else.
- Align's published policy for iTero says the software license does not transfer from the seller; the buyer receives a new license through Align's transfer process, and existing warranties end at transfer.
- Recurring software cost differs by brand: iTero requires a service plan after the first year, 3Shape offers a paid TRIOS Care plan or a free TRIOS Only agreement, and Medit markets its i700 with no subscription fees.
- Scanners age fast. A model near its end-of-support date can be close to worthless no matter how clean it looks.
- The wand, tips, cart or laptop, and calibration tools all matter. Missing accessories are common and add cost.
How an intraoral scanner works
An intraoral scanner is a handheld wand with a light source and one or more small cameras. As the operator moves the wand over the teeth, it captures thousands of images and the software stitches them into a three-dimensional surface model in real time. Different systems use different optical approaches, but for a buyer the practical parts are the same: a wand, a scanning tip (reusable and autoclavable, or single-use), a computer that runs the acquisition software (built into a cart, or a laptop), and a cloud or local platform to send the scans to a lab, an aligner company, or design software.
Because so much happens in software, scanners improve through updates, and older hardware eventually stops receiving them. That is the central fact of the used market: the hardware can be in perfect condition while its useful life is set by the manufacturer's support calendar.
Why used values vary so much by brand
With a dental chair, a used unit from any major brand holds value roughly in line with its condition. With scanners, the brand's business model drives resale value. Here is how the major approaches compare, based on the manufacturers' published materials at the time of writing. Policies change, so confirm current terms before you buy.
iTero (Align Technology)
Align publishes a formal policy on the transfer or resale of iTero scanners. In summary: the software license is personal to the original owner and cannot be transferred by the seller; Align grants a new license to the buyer as part of a supported transfer. Supported transfers must stay within the country of original purchase, both parties sign a transfer agreement, and the seller must reset the scanner and erase patient data. Align will not support transfers of scanners past their end-of-support date or of unclear origin, and says a scanner acquired outside the policy may not be activated. Warranties and service entitlements end at transfer, and the buyer may face evaluation, repair, training, or administrative fees. Align's service plan page states that a separate subscription service plan is required after the first year unless an extended plan was purchased up front.
For a buyer, that means a used iTero is really a purchase of hardware plus an Align transfer, plus an ongoing service plan. Reseller packages that bundle the transfer and a subscription term are common for this reason.
3Shape TRIOS
3Shape offers two ongoing agreements. TRIOS Care is a paid subscription that includes warranty, support, express replacement, and cloud storage. TRIOS Only is a free agreement that keeps the scanner scan-ready with basic software updates but without warranty or express replacement. 3Shape states that a subscription that is neither renewed nor switched to TRIOS Only has its license revoked, which cuts off access to the scanning software. For a secondhand unit, confirm with 3Shape or an authorized reseller, using the serial number, what it will take to license that scanner in your name and whether any hardware keys or activation fees are involved.
Medit
Medit has marketed its i700 with no subscription fees, and many of its apps are free to scanner owners, though some newer apps carry monthly or per-use charges. Medit's standard scanner warranty is one year. Without a mandatory subscription, a used Medit scanner's value rests more heavily on the hardware and on its support status. Ask Medit how warranty, registration, and account ownership work for a second owner.
Dentsply Sirona, DEXIS, and others
Dentsply Sirona's Primescan is often tied into CEREC chairside milling and its software ecosystem, so its value depends on whether you are buying into that workflow. The scanner line formerly sold by Carestream Dental now carries the DEXIS name (for example the IS 3800 family). Planmeca, Straumann, Ivoclar, Shining 3D, and others round out the field. For every brand, ask the same questions: license transfer, subscription, warranty, and end-of-support date.
What holds value and what doesn't
| Factor | Helps resale value | Hurts resale value |
|---|---|---|
| Software support status | Current generation, years of support ahead | Announced or near end of support |
| License transfer path | Clear, documented manufacturer transfer process | Personal license with no supported transfer, or unclear origin |
| Recurring cost | No mandatory subscription, or a free basic tier | Required paid plan the buyer must start fresh |
| Workflow fit | Open export formats, broad lab and aligner compatibility | Locked to one ecosystem the buyer does not use |
| Hardware | Clean wand, intact cable, all tips and calibration tools | Cracked housing, damaged cable, missing tips or calibration kit |
| Computer | Cart or laptop meeting current specs | Old computer that cannot run current software |
| Wireless vs. wired | Wireless models with healthy batteries | Worn batteries or charging docks missing |
The pattern is simple. Anything that makes the scanner easy for the next owner to license, support, and plug into their workflow holds value. Anything that makes the next owner start over with the manufacturer drains it.
What to inspect before you buy
Scanners are easier to test than most equipment because you can see the output immediately. If you can, scan a typodont or your own teeth with the unit at the seller's office, logged into software that shows it working, and export the file.
Used intraoral scanner checklist
- Serial number checked with the manufacturer: supported model, end-of-support date, and transfer eligibility
- Written quote for transfer, activation, evaluation, and any required subscription
- Seller has reset the device and removed patient data as the manufacturer requires
- Live test scan completed, with stitching and color working normally
- Wand housing inspected for cracks, and the scanning window or mirror free of scratches, stains, or haze
- Cable intact at both ends (wired models), or batteries and chargers working (wireless models)
- Tips counted, with their sterilization cycle limits known
- Calibration tool present and calibration completes successfully
- Cart or laptop meets the current software's requirements
- Export confirmed in the file formats your labs and aligner companies accept
- Seller's account released, so the scanner is not still linked to them
Tips are consumables
Reusable scanner tips have finite sterilization lives. Medit, for example, lists up to 150 sterilization cycles for i600 and i700 tips and up to 50 for the older i500. 3Shape specifies a pre-vacuum (Class B) autoclave cycle for TRIOS 3 tips. A used scanner that comes with worn tips needs new ones, and your sterilizer has to be able to run the cycle the tip maker specifies. If you are shopping sterilizers too, see tabletop sterilizers compared.
Red flags
Common expensive mistakes with used scanners:
- Buying a scanner whose manufacturer requires a formal transfer, without doing the transfer. The unit may simply not activate.
- Buying a scanner imported from another country. Several manufacturers do not support cross-border transfers.
- Assuming the seller's subscription or warranty comes with the unit. It usually ends at sale.
- Buying a model close to end of support because it is cheap. It will be cheaper still, and harder to use, in a year.
- Paying for a scanner that is still logged into the seller's account, or that contains patient data. That is also a privacy problem for the seller.
- Listings with no serial number, no live demo, and no explanation of why it is being sold.

Cost considerations
New scanner prices span a wide range. An industry price guide published in 2024 listed starting prices from under $10,000 for some value brands to around $34,000 to $35,000 for flagship models such as the iTero Element 5D Plus and Primescan, with 3Shape TRIOS starting near $19,000 and the Medit i-series near $13,500. Used prices depend heavily on the transfer and subscription picture described above. Certified pre-owned packages from resellers, which typically bundle the manufacturer transfer, some warranty, and sometimes a subscription term, often cost more than a private-party unit but remove most of the licensing risk.
When you compare options, compare total cost of ownership over the years you expect to use the scanner, not the purchase price. A rough framework:
| Cost line | Where it comes from |
|---|---|
| Purchase | Private seller, reseller, or manufacturer |
| Transfer or activation | Manufacturer's transfer policy and any evaluation or repair it requires |
| Subscription or service plan | Required for some brands, optional or absent for others |
| Tips and consumables | Reusable tips with cycle limits, or single-use sleeves and tips |
| Computer | Replacement cart or laptop if the existing one is out of spec |
| Add-on software | Design, ortho simulation, or other apps you actually plan to use |
| Repair risk | Out-of-warranty wand repair or replacement |
Hypothetical example (illustrative numbers only): Scanner A is a private-party unit at $9,000, but the buyer must pay a $2,500 transfer and evaluation fee and a service plan of $300 a month. Over four years that is $9,000 + $2,500 + $14,400 = $25,900. Scanner B is a newer unit at $15,000 with no required subscription, plus $1,200 in tips and a $1,500 laptop, for $17,700 over the same period. Scanner B costs more on day one and less over the life of the purchase. Plug in the real quotes for the brands you are considering; the structure of the comparison is what matters.
Also compare against your actual scan volume. If you send a handful of impressions a month and do not offer aligners, the return on any scanner is slower than the sales pitch suggests. New vs. used equipment for new grads walks through that decision more broadly.
Workflow and integration checks
Before you buy, confirm three integration points. First, the labs you use accept scans from that platform, either directly or through open file export. Second, any aligner company you use accepts that scanner. Some aligner programs are tied closely to particular scanners, so check. Third, the scanner software can run on your network and backup setup without creating a data-handling gap. Scan data is patient health information; how it is stored and who can access it is part of your HIPAA program, covered in our compliance chapter.
Selling a scanner you already own
If you are on the other side of the deal, the same rules work in reverse. A scanner you can hand over with a clean manufacturer transfer, a documented history, all tips and tools, and a working computer will sell faster and for more. Start the manufacturer's transfer paperwork early, reset the device and remove patient data as required, and release it from your account. See where to sell used dental equipment for channel options.
The practical approach
Treat a used scanner as a software purchase that happens to come with hardware. Check support status and transfer rules with the manufacturer first, compare total multi-year cost rather than sticker price, and test the unit live before paying. If the transfer path is unclear, a certified pre-owned unit or a lower-cost new scanner may be the better buy.
