Two used chairs of the same model can be listed at very different prices, one described as "refurbished" and one as "used." The price gap implies the refurbished chair had real work done. Sometimes it did: new hydraulic seals, rebuilt controls, new upholstery, a technician's test, and a written warranty. Sometimes "refurbished" means it was cleaned and photographed well.
This guide explains what the common labels usually mean, how the FDA distinguishes servicing from remanufacturing, what a genuine refurbishment includes for each equipment type, and how to compare offers so you pay for work that was actually done.
Key takeaways
- There is no single legal or industry-wide definition of "refurbished" for dental equipment. Ask for a written list of what was replaced, repaired, and tested.
- Manufacturer certified pre-owned programs are the most defined category. A-dec, for example, gives its Certified Pre-Owned equipment a 3-year warranty on A-dec manufactured components.
- The FDA treats restoring a device to original specifications as servicing or refurbishing, but treats work that significantly changes performance, safety specifications, or intended use as remanufacturing, which carries manufacturer obligations.
- New-equipment warranties usually do not follow used equipment. Midmark, for example, says its dental warranty covers only the first retail purchaser.
- Judge refurbished equipment by the seller's written warranty and parts list, not the adjective.
The labels, from newest to oldest
| Label | What it usually means | Warranty you can expect | What to verify |
|---|---|---|---|
| New | Never installed or used, sold by the manufacturer or an authorized dealer | Full manufacturer warranty | That the seller is authorized, so the warranty applies |
| New, unauthorized source | New in box, sold by someone who is not an authorized dealer | Often none from the manufacturer | Manufacturer's position on warranty for this seller |
| Demo or open box | Used for display, trade shows, or briefly installed | Varies; sometimes full, sometimes reduced | Hours of use, warranty start date, whether it was installed |
| Manufacturer certified pre-owned | Inspected and restored under a manufacturer program | Manufacturer's program warranty (A-dec: 3 years on A-dec components) | Which components are covered and for how long |
| Dealer refurbished or remanufactured | Disassembled, worn parts replaced, tested by the seller's technicians | Seller's own warranty; length and terms vary widely | Written parts and labor list, test results, warranty terms |
| Reconditioned | Serviced and cleaned, some parts replaced as needed | Short seller warranty or none | What specifically was done |
| Cosmetically refurbished | New upholstery, paint, or covers; mechanics untouched | Usually none on mechanics | That the seller is not implying mechanical work |
| Used, tested working | Removed from a working office, powered up and checked | Sometimes a short arrival guarantee | What "tested" meant, and by whom |
| Used, pulled from working office | Was in use before removal; not tested since | Usually none | Removal and storage conditions, service history |
| As-is | No representation of condition | None | Everything, ideally with your own technician present |
| For parts or not working | Known or suspected problem | None | Whether parts are worth the price |
Sellers do not all use these words the same way. The table describes typical usage, so treat it as a translation guide and confirm the meaning with each seller.
How the FDA thinks about refurbishing
Dental equipment such as chairs, delivery systems, sterilizers, and x-ray units are medical devices. In May 2024 the FDA finalized guidance on the remanufacturing of medical devices that clarifies terms the used equipment world often blurs.
- Servicing is repair or preventive or routine maintenance that returns a device to the original manufacturer's safety and performance specifications for its original intended use.
- Refurbishing and reconditioning, as the guidance uses the terms, fall on the servicing side: restoring the device to original specifications without significantly changing its performance, safety specifications, or intended use. Replacing worn parts and installing manufacturer updates are examples.
- Remanufacturing is processing, conditioning, renovating, restoring, or any other act that significantly changes a finished device's performance or safety specifications, or its intended use.
The distinction matters because the FDA considers remanufacturers to be manufacturers, with obligations such as registration and listing, quality system requirements, premarket authorization where applicable, and adverse event reporting. You can read the guidance on the FDA remanufacturing guidance page.
What a real refurbishment includes, by equipment type
Use this table to judge whether a "refurbished" description is credible. A seller who did real work can tell you which of these items were done.
| Equipment | Credible refurbishment typically includes | Cosmetic-only warning signs |
|---|---|---|
| Patient chair | Hydraulic seals or fluid serviced (or electric actuators checked), pump and motor tested under load, switches and foot control checked, new upholstery, base and shrouds repaired | New upholstery with no mention of lift, tilt, or controls |
| Delivery system | New tubing, o-rings, and control block service, handpiece air and water pressures set, waterline system cleaned, holders and arms adjusted | Cleaned and polished with original tubing |
| Operatory light | Arm tension and drift corrected, electrical checked, LED or bulb assembly tested, lens or shield replaced if hazy | New shield only |
| Tabletop sterilizer | Chamber inspected for pitting, door gasket replaced, valves and sensors checked, cycles run and verified, ideally with test results | Exterior cleaned, "powers on" |
| Compressor | Hours noted, heads rebuilt or checked, dryer serviced, tank inspected and drained, output tested | No hour reading or service record |
| Vacuum | Pump inspected and tested for capacity, seals and impeller checked, separator status documented | Runs, with no capacity figures |
| Handpieces | New turbine or bearings, chuck tested, speed and water spray checked | Polished exterior |
| Digital imaging | Software version confirmed, license transfer documented, calibration or image quality check, sensor cable inspected | "Works great" with no software details |

Warranties: what actually transfers
New-equipment warranties usually protect the first buyer from an authorized source. Midmark's published dental warranty, for instance, says coverage extends only to the first retail purchaser through an authorized Midmark distributor and is not transferable. A-dec's warranty applies to products purchased from A-dec or an authorized A-dec dealer, and A-dec separately offers a 3-year warranty on A-dec components sold through its Certified Pre-Owned program.
So for used and refurbished equipment, the warranty that matters is usually the seller's own. Get it in writing, and read it for:
- Length, and whether it starts at sale, delivery, or installation.
- What is covered: parts only, or parts and labor, and whether travel is included.
- Who performs warranty work, and where (on-site, or you ship it back).
- Exclusions, especially installation by someone other than the seller.
- What happens if the seller cannot fix it: repair, replace, or refund.
Worked example: comparing a refurbished chair to a used one
All numbers here are hypothetical and exist only to show how to compare offers.
Example: you are choosing between two chairs of the same model and similar age.
| Chair A: "refurbished" | Chair B: used, tested working | |
|---|---|---|
| Price (hypothetical) | $6,500 | $3,800 |
| Written work list | New upholstery, hydraulic seals and fluid, foot control rebuilt | None |
| Warranty | 6 months parts and labor, local technician | None |
| Your likely spend in year one (hypothetical) | $0 to $300 | $800 upholstery, plus possible hydraulic service estimated at $600 to $1,200 by your technician |
| Inspection cost | Optional | $250 technician inspection recommended |
| Estimated all-in, year one | $6,500 to $6,800 | $4,850 to $6,050 |
In this made-up comparison, Chair B is still cheaper even if everything goes wrong, but the gap narrows from $2,700 to a few hundred dollars in the worst case, and Chair A comes with a warranty and less downtime risk. If Chair A's seller could not produce a written work list, the comparison would collapse: you would be paying $2,700 for new upholstery and a promise. The label did not decide this. The paperwork did.
Questions to ask any seller of refurbished equipment
Refurbished equipment questions
- What exactly was replaced, repaired, and tested? Can I have that list in writing?
- Were parts new from the manufacturer, aftermarket, or used?
- Who did the work, and what is their training on this brand?
- What was the equipment's condition and history before refurbishment?
- Is any manufacturer warranty or program coverage involved, and has the manufacturer confirmed it?
- What does your warranty cover, for how long, and how do I make a claim?
- Were any modifications made beyond the original manufacturer's design?
- For digital equipment: what software version, and does the license transfer to me?
- Can my own technician inspect it before I pay?
- Who removes, crates, ships, and installs it, and who is responsible if it is damaged in transit?
Red flags
- "Refurbished" with no work list, or a work list that only mentions cosmetic items.
- "Like new" on equipment with visible wear in the photos.
- Claims that a manufacturer warranty transfers, without documentation from the manufacturer.
- Serial plates missing, painted over, or not matching paperwork.
- A warranty that requires you to ship heavy equipment back at your expense.
- Refusal to let your technician inspect before payment.
- Digital equipment with no way to confirm software license status.
When each category makes sense
| Choose | When |
|---|---|
| New | You want full warranty, predictable timelines, latest technology, or financing tied to new equipment; or the used market for that item is thin or risky (many digital devices) |
| Manufacturer certified pre-owned | You want a manufacturer-backed warranty at a lower price and the program covers the items you need |
| Dealer refurbished | The seller documents real work, gives a usable warranty, and is close enough to service it |
| Used, tested | You have a trusted technician, some repair budget, and time; chairs and mechanical equipment from major brands are strong candidates |
| As-is | Price is low enough that you can absorb a repair or treat it as parts, and you have inspected it yourself |

The bottom line
Treat every label as a claim to verify. Ask for the work list, the parts source, the warranty in writing, and the right to inspect. With those four things, you can compare a refurbished unit to a used one on real numbers. Without them, "refurbished" is just a more expensive way to say "used." Before you buy, run through the pre-purchase checklist and read what to expect from an inspection. When you are ready to shop, see what is listed on the ChairsideSource marketplace.
