3Shape TRIOS®

New scanner represents the next generation in digital impression taking.

Moving beyond scanning for copings and crowns alone, TRIOS is de­signed to eas­ily and efficiently deal with even complex clinical situations and quickly provides consistent, accurate, high-quality restoration results for an extensive range of indications.

Features and Benefits

TRIOS does not involve spraying, which can ruin scan accuracy, is uncomfortable for patients, and prolongs chairtime. Designed for ease of use, it can be used by both dentists and assistants after receiving brief instructions, and does not need to be held at a specific distance or angle for focus. Users can even rest the scanner on the teeth for support as they scan. It combines hundreds or thousands of 3-D pictures to create the final 3-D digital impression based on real data rather than interpolated artificial surfaces. It is 100 times faster than conventional video cameras, capturing more than 3,000 2-D images per second. Its autoclaveable tip, which can be flipped for alternating between scanning upper and lower jaws, provides optimal hygiene and meets clinical requirements. Its live 3-D visualization and motion-sensor interface enables dentists to view the digital impression being built on their touch screen during scanning, using the hand-held scanner to virtually rotate and turn the 3-D digital impression for easy viewing at all angles without touching the screen.

Tools for New Orders, Corrections, Validation

The TRIOS® order form, which can be customized to match the laboratory’s specific information requirements and offerings, makes it fast and easy to create new orders, attach 2-D images, and convey all case aspects to the laboratory. Dentists can conveniently mark detailed tooth color information directly on an illustration of the tooth.

When initial scanning results are not satisfactory, the TRIOS® Undo/Redo feature lets users edit their scans, delete unwanted details, and rescan specific regions as they build up flawless impression results.

TRIOS’s built-in tools for instant clinical validation help to ensure the high quality of the impression and tooth preparation while the patient is still in the chair (Figure 1). The Occlusal Clearance tool measures distance to ensure adequate space for the particular restoration, and the Insertion Direction tool controls prepared teeth for convergence/divergence. Rotate-and-zoom functionality lets dentists easily validate an impression’s quality on their screen and add comments to the laboratory directly on the 3-D image.

Laboratory Communication

The Communicate™ solution, which is optimized for sharing case information as 3-D images, offers dentists immediate and efficient 2-way communication with their laboratory to help them ensure optimal results. For example, laboratory technicians can verify details in the digital impression sent from the clinic, laboratories can send their design and margin line proposals and get back comments from the dentist, and dentists can view and discuss with their patients the virtual diagnostic wax-ups sent from the laboratory (Figure 2 and Figure 3).

Multiple Indications, Flexibility

TRIOS scans allow dentists to work with the laboratory of their choice and enjoy a wide range of dental indications, laboratory technician expertise, and a flexible choice of materials. TRIOS supports crowns, bridges, inlays, onlays, and veneers with subgingival preparation. TRIOS’s scan accuracy enables dentists to easily capture single-implant positions, using validated scan-bodies, and improve final esthetics by adding a scan of the soft-tissue emergence profile. 3Shape laboratories receiving pre-preparation digital impressions can use their CAD software to produce and send back cost-efficient temporaries and diagnostic wax-ups in highly esthetic designs based on the digital impression alone.

As TRIOS is not tied to a specific model provider, dentists and laboratories can shop freely among model types, manufacturing methods, and model services to match their models to the specific patient case, while optimizing turnaround time and costs. Laboratories using 3Shape CAD can offer support for fully functional implant models.


With features geared to a dental clinic’s internal workflows and external service needs, the TRIOS system’s technology advancements has set new standards for impression-taking in terms of accuracy, speed, and ease of use, providing clinicians with new ways to see more patients and deliver consistent, high-quality dental care.
