Dentsply Sirona · Dental Equipment · $38,000 – $75,000
A unit with under 8,000 scans and clean service records sits at $55K–$65K; anything over 12,000 scans or a service gap longer than 18 months drops to $38K–$48K. Tube replacement alone runs $8,200–$10,500, which kills margins on high-hour units.
Open the tube housing and look for dust accumulation or discoloration around the x-ray port - indicates environmental stress or poor maintenance. Check the calibration logs in the software; if the last service is more than 24 months old, the alignment is suspect and recalibration will cost you $2,100–$2,800. Spin the gantry by hand through a full rotation and listen for grinding or hesitation - replacement bearings aren't cheap.
Southern California and Arizona are glutted right now because Pacific Dental Services and Western Dental oversupplied the market with used units after consolidations in 2022–2023. Northeast (Boston, NYC) has tighter inventory and commands $8K–$12K premiums because DSOs there hold equipment longer.

Lease if you're under 15 locations or want predictable CAPEX. Aspen Dental leases theirs; they pay $1,400/month all-in and swap every 6 years. If you're 20+ locations and keep equipment 7+ years, buying at $52K and reselling at $28K–$35K in year 7 is smarter math than $1,500/month × 84 months.
At 8% APR over 60 months on a $55K unit, you're looking at $1,100/month principal + interest. Throw in maintenance ($180/month warranty, $300/month if you self-insure), and you're at $1,480–$1,580. Leasing at $1,400 all-in starts looking reasonable unless your scan volume justifies the wear.
Dentsply rates the tube at 200,000–250,000 exposures. Most clinics hit 10,000–15,000 scans per year, so you're looking at 15–25 years of life - but the software becomes obsolete in 8–10 years. That's why Heartland Dental cycles these every 6 years regardless of tube hours.

I source units directly from retiring practices and DSO upgrades, which saves buyers 15–20% versus going through equipment brokers who mark up 30%. I also have a tech who can spot $6K in hidden repair needs before you buy, which has saved my repeat clients an average of $11,200 per unit.
