3Shape TRIOS Review: Models, Features and Pricing

The 3Shape TRIOS range is one of the most widely benchmarked intraoral scanner families on the market — four distinct models covering everything from a wired entry-level unit to a wireless flagship with AI-assisted diagnostics. If you’re evaluating whether TRIOS belongs in your practice, here’s what the lineup actually looks like, what each model does differently, and where the trade-offs sit.

For a broader view of how TRIOS stacks up against competing platforms, see our guide to the best intraoral scanner options in 2026, or check intraoral scanner price benchmarks to put the figures below in context.

The Four TRIOS Models, Explained

TRIOS Core — The Entry Point

TRIOS Core is 3Shape’s wired, entry-level model. It delivers accurate color digital impressions and connects to the 3Shape Unite ecosystem, so labs receive scans in a single click — no file downloads, no email chains. For practices that want a clinical-grade scanner without the cost of wireless hardware or advanced diagnostics, Core is the logical starting point.

TRIOS 3 — The Workhorse (Refreshed 2024)

The TRIOS 3 has been in continuous clinical use since 2015. A 2021 study by Nulty et al., published in Dentistry Journal, found TRIOS 3 accuracy comparable to the Dentsply Sirona Primescan and statistically better than several other scanners tested. That’s a meaningful baseline.

The 2024 refresh moves the connection to USB-C and shrinks the pod by 10% while cutting its weight by 30%. It’s still wired, which some clinicians consider a limitation and others consider a non-issue. The hardware is powered entirely by PC — no separate power brick.

TRIOS 5 — The Everyday Wireless Model

Launched in 2022, the TRIOS 5 has since won six dental industry awards for best intraoral scanner, plus a Red Dot design award, according to 3Shape. It’s the brand’s smallest and lightest scanner, 20% lighter and 30% smaller than TRIOS 4.

The clinical case for TRIOS 5 is built around its ScanAssist alignment engine, which builds the 3D model in real time without the calibration step — the scanner is calibration-free. Infection control is handled by a closed autoclavable scan tip (cleared by FDA, per 3Shape; tips are rated to 100 autoclave cycles) plus ultra-thin disposable sleeves. The mirror is sealed, which keeps dust out of the optics.

TRIOS Share, a free activation, lets the wireless TRIOS 5 work on any PC or Mac in the practice — useful for multi-chair setups without dedicated scanner stations.

TRIOS 6 — The Flagship

The TRIOS 6 is only available in a wireless configuration (pod or MOVE Pro). Its headline differentiator is hyperspectral imaging, combining Near Infrared, Blue, and White light to capture geometry and color detail at up to 110% higher resolution than its predecessor, according to 3Shape’s own figures. That’s a vendor-reported spec and hasn’t yet accumulated the depth of independent study that supports the TRIOS 3.

The bigger clinical story may be Dx Plus — an AI diagnostic layer trained on thousands of scans that identifies surface caries, tooth wear, gingival recession, and plaque, and estimates severity. One important caveat: TRIOS Dx is not cleared by the FDA for clinical use in the US. Practices evaluating the TRIOS 6 for US deployment need to factor that in.

The 3Shape TRIOS and Unite 25.2 software update (2025) introduced Dx Plus and the TruAbutment ioConnect all-in-X workflow for TRIOS 6 users.

Scanning Technology

All TRIOS scanners capture approximately 2,500 images per second. From roughly every 100 images, the system generates a sub-scan — a point cloud with color data. The engine reconstructs the 3D model continuously, which avoids the stitching errors that can compound during longer scans. That’s the architecture behind the accuracy numbers in the published studies.

The 3Shape Unite Ecosystem

Buying a TRIOS scanner means buying into 3Shape Unite, the workflow platform that connects to 60+ practice management systems and over 2,000 dental companies, labs, and treatment apps. For same-day restorative workflows, TRIOS scanners integrate with Dentsply Sirona’s Primemill and Primeprint via Unite and DS Core for in-office milling and printing.

3Shape Automate, the AI crown and nightguard design service, accepts TRIOS scan uploads and returns completed designs in minutes. That kind of downstream integration is where the ecosystem argument is strongest — though it’s worth asking your lab and PMS vendor whether their specific workflows are already supported before assuming they are.

Pricing

Per 3Shape’s published pricing, TRIOS 5 starts from $25,900 (excl. tax and shipping). Other models span roughly $12,800 to $28,800 on the same basis. The first year of TRIOS Care — covering onboarding, training, support, warranty, and express replacement — is bundled into the purchase price. After year one, practices choose between continuing TRIOS Care or switching to a zero-cost TRIOS Only plan.

These are list prices. Actual quotes vary by region, configuration, and any bundled software. Verify current pricing directly with a 3Shape representative.

What to Make of It

For most general practices entering digital impressions, the TRIOS 5 hits the most useful balance of portability, infection control, and clinical evidence. The TRIOS 3 remains a sound, well-studied wired option for practices where wireless isn’t a priority. TRIOS 6 is compelling on paper, but the US FDA status of Dx limits its clinical value in American practices for now — and the independent evidence base hasn’t caught up to the marketing yet.
