Trios 4 - Key specifications
- Color scanning capability with 16-bit depth processing - catches shade and texture in single pass, cuts chairtime by 4–6 minutes versus traditional impression
- 590 micron minimum feature capture - tight enough for margin lines and veneer preps, matters for crowns because you skip the second scan 40% of the time
- Optical resolution 800×600 at 30fps - speed here prevents patient gag reflex during posterior scanning, directly reduces retakes
- Integrated WiFi + USB-C dual connectivity - WiFi drops in older clinics with thick walls; USB-C backup saves you a service call when the network flakes
Trios 4 price overview
Units under 1800 hours run $38,000–$42,000; anything past 2500 hours drops to $22,000–$28,000 because camera module replacement runs $4,200–$5,600 and most buyers skip it. Service history gap over 8 months is a red flag - tells you the clinic didn't maintain it.
Buyer's checklist for Trios 4
Open it up and check the camera lens for dust or fungus inside the optical path - that's $2,800 minimum to fix and 3Shape won't warranty it. Count the autoclave cycles on the tip - over 800 cycles means the tip connector starts losing contact. Ask for the last calibration date and calibration block condition; if the block is scratched or cloudy, factor another $1,400 for replacement.
US Market overview
Southern California DSOs (Aspen Dental, Pacific Dental Services) are rotating out Trios 3s and buying used 4s at volume - creates inventory glut around $28,000–$32,000 in the LA/OC market. Texas and Florida are still paying $36,000+ because DSO adoption there is 18 months behind the coast.

Trios 4 - FAQ
Trios 4 exports to Invisalign's platform natively, zero extra software. You don't need iTero unless your ortho partner demands it. Heartland Dental dumped their iTeros for Trios across 180 locations - that tells you something.
Camera module fails first - hits about 8–12% of units between 2000–3000 hours. Trigger switch on the handpiece is second at 6%. If you're past 2500 hours and handpiece is original, budget $800–$1,200 for replacement handpiece within 12 months.
Not 5 years. Realistically 3–4 more years if you maintain it and replace the camera module at 2800 hours ($5,600 all-in with labor). After 4000 hours, depreciation craters and repair costs eat your margins - better to rotate it out.

Why buy through TechCosmetic broker?
I can move a unit from your clinic to a buyer in 8–10 days instead of 6–8 weeks if it has clean service records and under 2200 hours. That's worth roughly $3,200–$4,100 in carrying cost and space you free up immediately.
