Trios vs iTero intraoral scanner comparison: which one to choose in 2026
The market for intra-oral scanners has exploded in recent years, led by two giants: 3Shape Trios and iTero (Align Technology).
The choice of one or the other has a direct impact on the accuracy of your digital impressions, workflow speed and ergonomics, as well as compatibility with your digital laboratory and CAD/CAM tools.
In this article, we take an in-depth look at Trios vs. iTero, to help you choose the intra-oral scanner best suited to your practice and digital workflow.
Trios: precision and speed for digital workflow
- Highlights
Excellent precision (ideal for complex restorations, bridges, onlays, inlays, implants).
Ultra-fast capture thanks to continuous scan technology.
Fluid, modern interface.
Open connection, much appreciated by 3D modeling labs.
Compatible with a wide range of CAD software (including Exocad, 3Shape Dental System).
Versions available: Trios 3, Trios 4, Trios 5 portable without external battery.
- Weak points
High initial investment.
Subscription recommended to take advantage of the complete 3Shape ecosystem.
Requires high-performance computer configuration.
iTero: the #1 choice for orthodontics and the Invisalign ecosystem
- Highlights
Unrivalled Invisalign integration (simulation, automatic planning).
Excellent scan stability thanks to ergonomic sensors.
Ideal for orthodontics, aligners and splints.
TimeLapse function: monitor the patient’s oral evolution.
Simplified workflow for sending cases to Invisalign and other certified partners.
- Weak points
More closed ecosystem: less flexible than Trios for CAD/CAM.
Less suitable for complex prostheses than open systems.
High cost + monthly fees for cloud services
- For what type of practice?
Orthodontic practices.
Practitioners who perform many Invisalign treatments.
Dentists looking for an easy, turnkey workflow.

Trios vs iTero: which is the better choice?
👉 Choose Trios if :
You work a lot with fixed prostheses, implants and complex modeling.
You want a workflow that’s open, flexible and compatible with the majority of laboratories and CAD/CAM solutions.
Speed and precision are your top priorities.
👉 Choose iTero if :
A large part of your business is orthodontics.
You regularly offer Invisalign to your patients.
You’re looking for an easy, fully integrated and automated workflow.
Which dental scanner for a 3D digital lab workflow?
If your practice works closely with a 3D design laboratory (such as Dental3DDesign), here’s what counts:
✔ STL / PLY file formats
Trios produces open files that can be used directly in CAD modeling.
✔ Exocad / 3Shape / other CAD compatibility
Trios is the most versatile choice for prosthetic modeling.
✔ Quick exchange and correction
The cleaner and more accurate the scan, the less the lab has to retouch → faster workflow.
➡ Conclusion for lab workflows: Trios is often the most suitable choice.
Conclusion: Trios or iTero? The 2026 verdict
Both scanners are among the best solutions on the market, but their focus differs:
Trios = the precision and freedom of an open ecosystem
iTero = the fluidity and power of an integrated orthodontic system
So the choice depends mainly on your practice.
Make the most of your scanner with professional 3D modeling
Whatever your scanner (Trios or iTero), the quality of the final result also depends on the digital modelling performed by your laboratory.
