Align · Dental Equipment · $20,000 – $40,000
Units under 3,000 hours with clean service records sit at $28,000–$34,000. Jump to $18,000–$22,000 if you're buying 5,000+ hours on the odometer or there's a service gap longer than 18 months.
Pull the handpiece and look for hairline cracks in the optical window housing - common failure point around 4,000 hours and replacement runs $3,200–$4,100. Check the USB and power ports for burn marks or corrosion; if you see that, the board is next. Fire it up and do a full-arch scan on a phantom model yourself - don't trust the seller's video.
California dental groups and DSOs are chewing through used scanners because insurance is finally paying better for digital impressions, so West Coast supply tightens every Q4. Texas and Florida chains are slower to adopt, which means you find better deals there but longer sell timelines.

Every 4,000–5,500 hours you're looking at optical degradation. It's not a catastrophic break - you just start seeing soft focus on distal edges. Cleaning the lens with the right swabs helps, but plan for a $1,600 lens cartridge replacement around that mark. Aspen Dental told me they budget for it as preventive maintenance now.
Software sync errors where the machine won't connect to the Align cloud platform - happens in roughly 30% of used units. It's usually a network config problem or outdated firmware, not hardware. Takes a tech 90 minutes to sort, so budget $600–$900 for a house call if you don't have in-house IT.
It's real, but it's not a replacement for your hygienist's assessment. It catches 73–81% of proximal decay in clinical studies, which is better than bitewings alone. Don't sell it as a diagnostic tool by itself - use it as a second pair of eyes, and your patients will appreciate the upsell into preventive treatment.

A working 5D saves a typical 12-chair DSO practice about $18,000 per year in lab remake costs and patient no-shows caused by bad impressions compared to polyvinyl. It also cuts your impression appointment time from 35 minutes to 18 minutes, which means you squeeze 2–3 extra patients per operatory weekly.
