DiOS® 4.0 (Medit i500)

DiOS® 4.0 (Medit i500)

The DiOS® 4.0 intraoral scanner combines all the benefits of digital scanning technology: lifelike colour scans, realistic, accurate and detailed images, maximum openness during data exchange and a remarkable speed available at an unbeatable price.

Digitise your Workflow!

  • High ROI
    The design and software allow for an unparalleled performance at a very competitive price.
  • High Resolution 
    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.
  • Impressive speed
    Using two high-speed cameras, the DiOs® 4.0 scans quickly and efficiently.
  • Vivid color
    Precise-colored scans can distinguish between soft-tissue, plaque and tooth stumps.
  • Flexibility
    The open CAD/CAM system allows to export STL files and share it with your prefered lab, or to easily transfer files and track your progress throughout the entire workflow. 
  • NEW: Smart Scan Filtering
    Three filter options help to remove unnecessary soft tissue, leaving only the necessary gingiva or teeth data.


  • Powderless
  • Small tip
  • Video type
  • Lightweight (276 g)
  • Single button control



Optimal Software and Hardware Combination

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 patient.

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.

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).

Occlusion Analysis

The DiOS® 4.0 scan software automatically finds the occlusion with a simple scan of the bite. Any interference between the maxilla and mandible are displayed on an easy-to-read color map.

Pre-Operation Scan

You can perform a pre-operation scan of a patient's teeth. 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.


It is easy to take 2D images with 3D model data and share them with a laboratory.
