3Shape's D-250™ is a state-of-the-art 3D scanner designed to create accurate 3D scans of dies/stumps, inlay preparations, bridge preparations, bites/antagonists, wax-ups and full dental casts.

3D copies of the customer's dental casts or dies/stumps are available within minutes. Saved in an open format, they can be used directly in 3Shape's modeling software package, DentalDesigner™ or in other third-party software applications.

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


Example of scanned preparation including the opposing teeth scanned from the bite impression



  • 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.

  • Fast and easy positioning of the objects 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 object are automatically captured: the object is placed on a rotation plate (360 degree rotation) and is moved along a linear axis (translation) and a secondary rotation axis (tilt) to ensure maximum exposure of the geometry to the cameras and laser

Versatility
The D-250 handles most types of dental models, according to your scanning needs: dies/stumps, inlays (incl. deep inlays), bridge preparations (from 2 to 14 units), bites, wax-ups (crowns, bridges), pontics, full casts (up to 16 units), overbites (double scans)

Open file formats
The 3D files can be saved and exported in a number of standard formats, such as STL. This makes the D-250 fully compatible with all open solutions and applications available on the market

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

One-button scanning
Just place the object (cast, bridge, die) in the scanner -no precise positioning is necessary. Click on one button in the scanning software and 3Shape's unique scanning technology ensures a complete coverage of the whole geometry of the object, including potential undercuts

Alignment of scanned parts
Using 3Shape's unique algorithms, the scanner automatically aligns different scanned parts (upper and lower bite, stump and dental cast etc.)

Automatic 3D model creation from scanned data
The scanner software automatically creates a surfaced 3D model from the acquired point cloud data. The 3D files are ready to be modeled in 3Shape's DentalDesigner™ or other third-party software applications
