High ROI

The DiOS® 4.0 scanner was created with a high Return On Investment in mind. The design and software allow for an unparalleled performance at a very competitive price.


The DiOS® 4.0 uses an open CAD/CAM system, allowing you to export STL files and share it with your preferred lab, or to easily transfer files and track your progress throughout the entire workflow.

Impressive Speed

Using two high-speed cameras, the DiOS® 4.0 scans quickly and efficiently. With its intelligent scan detecting algorithm, the DiOS® 4.0 picks up where it left off for a smooth scanning experience.


The DiOS® 4.0 does not require the use of powder for regular cases, making the scanning process more seamless and the experience more pleasant for the patient.

Small tip

The small tip on the DiOS® 4.0 is beneficial to both the user and the patient through simpler maneuverability and improved patient comfort.

High resolution

The DiOS® 4.0 produces realistic images which are high in resolution and rich in detail, allowing you to distinguish between tooth structure and soft tissue for easy identification of margin lines and undercuts.

*Accuracy test in vitro was conducted by Yonsei University College of Dentistry according to the methods in “Accuracy comparison analysis on scan data of single tooth, quadrant, and full arch between two types of intraoral scanner, i500 and Trios 3” Ji-Man Park, 19 December 2018.

**Accuracy test in vivo was conducted by Medit.

Video type

There is no need to worry about choppy results with the DiOS® 4.0 as it takes rapid video based scans, capturing more data in a short period of time. The resulting image taken by the dual cameras is hence smoother and more detailed.


Scanning can be uncomfortable and tiring, especially if you’re using a heavy scanner. But that problem has been eliminated with the DiOS® 4.0 scanner which is light in weight and easy to hold, making the process a comfortable one for you.

Vivid color

The DiOS® 4.0 scanner produces precise-colored scans which can distinguish between soft tissue, plaque and tooth stumps.

Single button control

The single button of the DiOS® 4.0 allows the user to start and stop the scan at any moment without having to reach for the computer. Press the button down once to start scanning, and another time to stop. When the scan is complete, hold it down for approximately 3 seconds to move to the next scanning stage.

Perfect Software and Hardware Combination
Using the DiOS® 4.0 and the Medit Link software is a pleasant experience. It is easy to understand for all users, and it is simple to incorporate the system into your practice or lab.

User-friendly UI

The software user interface is intuitive with a streamlined process so you can spend less time on scanning and more time on diagnosing and treating your patients.

Pre-Operation Scan

You can perform a pre-operation scan of a patient’s teeth and utilize this data for a variety of uses. With this pre-operation scan data, the post-operation scan can be performed more quickly and easily. The data can also be used as reference data in the modeling process to assist you in creating more natural prosthesis.

Impression Scan

This function supports composite scanning operations which use both embossed oral scan data and engraved impression scan data. With just a simple scan, both data can be sorted and merged in real-time and used for modeling.

Undercut Area Analysis

This feature allows you to analyze the undercut area based on insertion direction. You can set the insertion direction via two methods (auto or manual direction).

Automatic Alignment

The DiOS® 4.0 scan software automatically finds the occlusion with a simple scan of the bite.

Occlusion Analysis

The occlusion analysis function quickly analyzes the occlusal state of the maxilla and mandible, displaying the results in a color map with numerical values. The color map shows the degree of occlusion in different colors and displays the corresponding values when you move the cursor over each area. You can also check the distance between the prepped tooth and its antagonist.

Scan Replay

The scan replay function allows you to replay a previous scan process. By virtually showing the scan tip and scan area, you will be able to see how it was scanned, enabling you to identify and improve your scanning methods or habits.

High Resolution Scan

You can select specific parts of the tooth to scan at high resolution. This function allows you to scan in HD only where it is required, enabling efficient management of scan time, data capacity etc. The selected area is displayed in a different color for ease of use.

Lock Area

You can lock the scan area by painting it and locked (colored) area will not be updated by further scanning. Use this feature to fix retracted gingiva after immediate scanning as it might collapse. You can still trim the locked surface. Deleted locked surface can be re-scanned.

HD Camera

Along with 3D Scan function, this function allows you to use the scanner as intraoral camera to take HD pictures. You can share images with a lab and use them when consulting patients.
