3Shape · Dental Equipment · $22,000 – $42,000
A Trios 4 with under 8,000 logged scans, clean service history, and a dock that holds charge sits at $38,000–42,000. Drop that to 15,000+ scans with a calibration gap over 18 months, and you're looking at $22,000–28,000 - and you'll spend $1,200 on recalibration before clinical use.
Fire it up at the seller's location; run a calibration check yourself using the built-in diagnostic (takes 90 seconds). Look at the handpiece for hairline cracks around the tip - common wear point, costs $800–1,100 to replace. Pull the service logs from 3Shape's cloud portal; if there's a gap longer than 14 months between calibrations, the unit drifted and you're absorbing calibration cost.
Southern California DSO expansion is pushing used Trios 4 demand hard - Pacific Dental Services is actively acquiring practices in the LA/OC corridor and they standardize on Trios. Texas and Florida markets are slower because smaller practices still run Itero or Cerec acquisitions.

Different lanes. Trios 4 has better color accuracy and faster workflow in cosmetic/ortho; Medit is cheaper upfront ($28k–34k used) and integrates easier into mixed-brand offices. iTero locks you into Align's ecosystem. Pick based on your lab partners and case mix, not hype.
Nope. Dock battery replacement runs $280–350 and takes 15 minutes. Wireless module swap is $600–750 if that's the issue. Neither one kills the deal unless you're buying a $22k unit and suddenly need two grand in fixes - then you renegotiate.
A busy practice (8–10 hygiene chairs) runs 6,000–10,000 scans per year. If you're buying one with 18,000+ scans in three years, the thing got hammered and you need a full recalibration before placing it in your clinic. Check the clinic size where it came from.

I can move a documented, calibrated Trios 4 in 6–8 weeks vs. 4+ months on your own; that's cash flow that matters when a buyer's financing depends on equipment ready to scan day-one. I also handle the 3Shape account transfer and dock reconfiguration, which saves you 20+ hours of back-and-forth with tech support.
