Dentsply Sirona · Dental Equipment · $38,000 – $75,000
A machine in the $38K–$48K range usually has 8,000–12,000 tube hours logged and documented service; anything below $40K without a service record from the past 24 months is a red flag because you're looking at $2,500–$4,500 in immediate sensor calibration and tube inspection. The $65K–$75K units typically sit under 5,000 hours with full factory service history and current software licensing.
Get the tube hour readout from the control panel - if the seller can't pull it in 30 seconds, walk. Physically inspect the bite block and forehead rest for deep cracks; replacement is $800–$1,200 and dealers know it. Run a test scan on your own phantom (bring one) and compare the DICOM file metadata dates to the service records - gap over 18 months means either the clinic stopped using it or ignored maintenance.
California DSOs are consolidating out of 3-4 older single-head pan/ceph setups into one SL 3D per location, so inventory is competitive in Orange County and LA metro; Heartland Dental's expansion into Arizona is driving demand there because they standardize on this model across their platform. Prices have dropped 8–12% in the past 18 months because supply caught up to the initial hype.

Yes, straight up. The SL 3D is faster, the image sharpness is 20% better at 75 microns, and Dentsply's software updates actually work - not like some older Planmeca boxes where you're stuck on 2019 software because the hardware is too old to patch. Only scenario you'd hesitate: if you run high-volume implant surgery and need full-skull imaging daily, then the larger FOV on a Vatech Green 15 might make sense, but you'll pay $58K–$82K and need more shielding.
Factory spec is 50,000 hours before performance drops below clinical tolerance. In a typical DSO chair running 6–8 scans per day, you're at 2,000–2,500 hours per year, so you get 20–25 years if the machine is maintained. Tube replacement runs $6,500–$8,200 installed, but I've only seen three calls for that in 18 years - most practices upgrade before they hit the limit.
Used machines are typically sold AS-IS, no warranty unless I broker a dealer refurb (which I do for +$3K–$5K markup, totally worth it). Parts - sensor module, tube, collimator - I stock or have landed in 48–72 hours through my distributor relationships. Dentsply's authorized dealers charge 25–30% markup over what I pay, so buying through me locks that out.

I source these with full service history and calibration done pre-delivery, which saves a clinic 3–4 weeks of downtime and $1,800–$2,200 in calibration labor they'd eat otherwise. You also get me on speed dial if the sensor acts weird in month two - that's worth the 6–8% markup over private-sale pricing because walk-in clinics don't have an IT department.
