Dentsply Sirona · Dental Equipment · $38,000 – $75,000
A unit with under 8,000 tube hours and no service gaps in the last 24 months lands around $58K–$68K; add 12,000+ hours or a year without records and you're dropping to $40K–$48K because calibration and detector replacement loom. Detector replacement alone runs $4,200–$5,800 and shows up fast on machines left in storage.
Walk the tube head through a full 360 - listen for grinding or hesitation, not just smooth rotation. Request the last three service reports and ask specifically for detector responsiveness numbers (should show >95%); if they don't have them, the unit's been running blind. Check the ceph arm for play - you're looking for zero wobble when you push sideways; even 2mm slop means realignment at $800–$1,200.
Southern California dental groups are hunting these units because Medi-Cal reimbursement actually moved for CBCT diagnostics in 2023, pushing clinics toward second-unit capacity without capital spend. Texas is equally hot - Sage Dental expanded 14 locations last year and needed backup imaging fast.

No, it's not overkill. Sage Dental has locations with 4 ops doing 120 scans a month on one SL 3D with zero downtime. But if you're at 15–20 scans monthly, a used i-CAT FLX at $24K is smarter.
Detector lasts 5–7 years with normal use (under 12,000 hours). Replacement is NOT DIY - Dentsply requires factory alignment, $4,800–$5,800 total cost. You'll send the unit in or a tech comes to your clinic.
ProMax has a larger 17x13cm FOV but slower scan time (13 seconds vs. 11 on the Orthophos) and bleeds into imaging workflows. The Orthophos is 12% faster, parts are cheaper (Dentsply owns the supply chain), and when Western Dental had to choose five years ago, they went Orthophos on cost-per-scan math.

I can pull full detector calibration reports and service logs in 48 hours that most sellers won't share until day 5; that alone saves you a $3,200 surprise once it's in your operatory. I've also negotiated freight and installation bundled in three times this year, which typically runs $2,400–$3,100 separately.
