3Shape's R-250 is a state-of-the-art 3D scanner used to create accurate 3D scans of full dental models in a few clicks.

3D copies of customer's dental casts are available after a few minutes. Saved in an open or locked format, the models can be used directly for storage, analysis and fabrication of orthodontic treatments. They can also be saved in an encrypted format for online communication between practitioners.

The scanning system runs on a standard Windows-based PC (included) and requires no specific expertise to be operated.

Examples of bite registrations: the plasters are scanned and processed using 3Shape's R-250™ 3D scanner.



  • Fast - total scan and processing time for one die: 45 secs.
  • Full coverage scans all undercuts and inlay preparations automatically using a 3-axis/2 cameras setup
  • Easily scans the antagonist from a bite impression
  • High stability and minimum maintenance needs
  • Scans all colors - laser and camera parameters are automatically adjusted to the scanned material
  • Easy remakes - all user input (modelling operations) is saved along with the 3D models

The scanning of a dental cast is performed using an optical scanning system, in which laser planes are projected onto the object. High-resolution digital cameras acquire images of the lines created on the cast. 3Shape’s unique processing software automatically processes the images and creates accurate and fully surfaced 3D models.

Unique features of the R-250 scanner guarantee superior scan results. The scanner captures the full geometry of the dental cast in one scanning session with high accuracy, including undercuts present on the original study model.

  • Fast and easy positioning of the casts in the scanner without compromising accuracy.
  • Consistently high levels of precision are guaranteed by projective geometry and a novel calibration of the laser, cameras and axes.
  • Undercuts on the original model are automatically captured: the object is placed on a rotation plate (360 degree rotation) and is moved along a linear axis (translation) and rotated around a third axis (tilt) to ensure maximum exposure of the geometry to the cameras and laser.

Models of plaster scanned using 3Shape's R-250 dental 3D scanner can be used for storage purposes. Files can be locked in order to avoid digital alterations of the 3D virtual model.

Versatility
the R-250 can scan all types of dental models.

Open or locked file formats
the 3D files can be saved and exported in a number of standard formats, such as STL. This makes the R-250 fully compatible with all open solutions and applications available on the market. The 3D scanned data can also be locked to prevent the virtual model from being digitally altered.

High and consistent levels of accuracy
Continuous validation using Mititoyo™ metrology gauge blocks

One-button scanning
just place the cast(s) in the scanner -no precise positioning is necessary. Click on one button in the scanning software: 3Shape’s unique 3-axes scanning technology ensures a complete coverage of the whole geometry of the cast, including potential undercuts.

Alignment of scanned parts
using 3Shape’s unique algorithms, the scanner aligns the upper and lower model either based on cutting planes or using an additional alignment scan.

Automatic 3D model creation from scanned data
the scanner software automatically creates a fully surfaced 3D model from the acquired point cloud data. This data processing can take place on a separate PC, which frees up capacity to maximise scanning volume.

3D Viewer
3Shape provide a 3D viewer that allows for remote viewing of 3D files.
