If you’re deciding between iTero and Primescan, the short answer is: both are top-tier scanners, but they suit different practice models. Primescan holds a consistent accuracy edge in independent research. iTero Lumina closes that gap — at least in manufacturer-supported data — and pulls ahead on diagnostic features and file format flexibility. The right choice depends far more on your ecosystem and workflow than on raw specs.

iTero vs Primescan: What the Accuracy Research Actually Shows

Accuracy comparisons between intraoral scanners get murky fast, because who funds the study matters. Keep that in mind here.

Independent peer-reviewed evidence has consistently placed Primescan at or near the top. A 2022 study published in BMC Oral Health ranked CEREC Primescan first among scanners tested for accuracy, ahead of Trios 4, Medit i500, and iTero Element 2. The Institute of Digital Dentistry uses Primescan as its reference benchmark when comparing other devices — that’s not a casual endorsement. A 2023 in vitro study of full-arch implant impressions (published via PubMed) tested 14 scanners including Primescan, iTero 5D, and iTero 2; Primescan produced the most accurate digital impressions of the group.

iTero’s picture looks different — though the context matters. Align Technology’s own ANA/ANSI 132 bench testing (July 2024) showed iTero Lumina outperforming Trios 5, CS3800, Medit i700, and Allied Star. An Align-supported in vitro study in the Journal of Dentistry (2025) found Lumina led on trueness (0.04% relative error) and precision (0.032%). Both results are real, but Primescan was not included in either comparison group. That omission is significant.

For the All-on-4 concept specifically, a PMC in vitro study found Primescan, iTero 5D, Trios 3, and Trios 4 all fell within acceptable trueness and precision thresholds — clinical parity, not a decisive win for either brand.

The practical takeaway: if implant or full-arch accuracy is your priority, independent evidence still favors Primescan. For restorative single-arch work, the gap is narrow enough that other factors should drive your decision.

Scanning Technology and Hardware

The iTero Lumina, launched February 2024, uses Align’s proprietary Multi-Direct Capture (MDC) technology: six cameras and five projectors at the wand tip, firing blue and green lasers through a diffractive element to produce a hexagonal capture pattern. The result is a maximum capture depth of 25 mm and a field of view three times larger than its predecessor, the iTero Element 5D. Align reports scanning speeds up to twice as fast as the 5D — per the manufacturer’s own data.

Primescan 2, announced September 2024, is built on the same optical engine as the original Primescan with a measured capture depth of up to 20 mm. The hardware upgrade isn’t the headline here; the architecture is. Primescan 2 is the first cloud-native intraoral scanner, processing scan data entirely through Dentsply Sirona’s DS Core platform. It doesn’t need a dedicated computer — any laptop, tablet, or mobile device with an internet connection works. That makes multi-chair or multi-site deployment genuinely simpler.

The catch: DS Core is a subscription service, and Primescan 2 requires a paid DS Core plan to operate. That’s a recurring cost that doesn’t exist in the same form with iTero, and practices should model it into any total cost of ownership calculation. See our intraoral scanner price guide for how to frame these numbers.

Ecosystem, Connectivity, and File Formats

This is where practice type really drives the decision.

iTero is built into the Align Digital Platform and integrates directly with Invisalign case submission — no workarounds, no third-party middleware. It also connects with cone beam CT data for third-party treatment planning. The lab network covers over 3,000 partners, per Align’s figures. On file formats, iTero Lumina exports STL, PLY, and OBJ — OBJ and PLY retain color data, which is useful for certain digital workflows and lab communications.

Primescan 2 exports STL only, according to clinical evaluations by the Institute of Digital Dentistry. For most restorative workflows that’s fine, but if color-scan data matters to your lab or implant planning team, it’s a real limitation. On the upside, Primescan integrates natively with CEREC CAD/CAM software and Dentsply Sirona’s milling and printing hardware (Primemill, Primeprint), enabling same-day crown fabrication in-office without additional software licensing.

If you’re an Invisalign-heavy practice, iTero wins on integration by default. If you’re running in-house milling with CEREC, Primescan is the natural anchor of that workflow.

Diagnostic Features: NIRI Is a Real Differentiator

iTero Lumina Pro includes Near-Infrared Imaging (NIRI), which can flag interproximal caries without ionizing radiation. The iTero Element 5D was the first device to combine 3D scanning, intraoral color imaging, and NIRI simultaneously. A 2021 multisite clinical study found NIRI comparable to bitewing radiographs for detecting interproximal lesions — a meaningful finding given how often patients defer X-rays.

Primescan doesn’t offer an equivalent. If caries co-diagnosis during scanning is a clinical or practice-differentiation priority, that’s a genuine gap. That said, NIRI isn’t a replacement for a full radiographic protocol — for more on how digital imaging fits together, see our piece on digital radiography in dentistry.

Which Scanner Fits Your Practice?

For orthodontic-forward practices or those with strong Invisalign volume, iTero Lumina is the obvious fit — the ecosystem integration alone justifies it. For practices running same-day CEREC restorations, Primescan 2’s native milling integration and cloud-native flexibility are hard to beat. For implant-heavy or surgical cases where full-arch accuracy is paramount, the independent research still points to Primescan. And if caries detection without radiation is a clinical priority, iTero Lumina Pro is currently the only option in this comparison that offers it.

Neither scanner is the universal answer. Get demos of both, ask each vendor for a full subscription and service cost breakdown, and test against your actual patient mix before committing.

Frequently asked questions

Is iTero or Primescan more accurate?

Independent peer-reviewed studies, including a 2022 BMC Oral Health study and a 2023 full-arch implant study, consistently rank Primescan at or near the top for accuracy. Align Technology's own data shows iTero Lumina outperforming several competing scanners, but Primescan was not included in those comparisons. For implant and full-arch work, independent evidence currently favors Primescan. For single-arch restorative cases, the difference is clinically narrow.

Does Primescan 2 require a subscription?

Yes. Primescan 2 operates entirely through Dentsply Sirona's DS Core cloud platform, and a paid DS Core subscription is required to use the scanner. This is an ongoing cost that practices should factor into the total cost of ownership alongside the hardware purchase price.

Can iTero and Primescan both send files to outside labs?

Both support open data export, but with a difference. iTero Lumina exports STL, PLY, and OBJ formats — PLY and OBJ retain color data. Primescan 2 exports STL only, according to Institute of Digital Dentistry evaluations. For most lab workflows STL is sufficient, but if color scan data is part of your digital submission process, iTero has the edge here. iTero also connects to a network of over 3,000 lab and implant partners, per Align's figures.

Does iTero offer caries detection that Primescan doesn't?

Yes. The iTero Element 5D and Lumina Pro models include Near-Infrared Imaging (NIRI), which can detect interproximal caries without radiation. A 2021 multisite clinical study found NIRI performance comparable to bitewing radiographs for interproximal lesions. Primescan does not currently offer an equivalent diagnostic imaging layer.
