4 Safety instructions
Always observe the following safety instructions when setting up, starting up and using the scanner:
1. The device may only be operated by adequately trained personnel instructed on the intended use of the device and the
following safety instructions.
2. We strongly advise against any use other than the intended use, as improper use may result in property damage and
personal injury.
3. The device is solely intended for use in dry, indoor rooms.
4. The device was developed and manufactured according to the applicable safety standards and with the utmost diligence.
However, the risk of electric shock, overheating or fire due to technical defects of single components cannot be ruled out
completely. Therefore always switch the device off when it is left unattended for extended periods, e.g. over night. This
will also benefit the environment as it reduces electricity consumption.
5. Only operate the device on a sturdy substructure (table, workbench, etc.) with a minimum weight bearing capacity of at
least twice the scanner net weight listed in the technical specifications.
6. To remove objects that dropped into the scanner or to clean the inside of the scanner, the device must first be switched
off using the on/ off switch E(see Fig. 2).
7. If you detect damage or a functional defect, mark the scanner as defective and prevent it from being further operated until
repaired.
8. Please be sure not to place anything other than the objects to be scanned into the scanner. Make sure no objects fall
through the scanner opening.

5.2 Operation of orthoX®scan
The key components of the 3D model scanner orthoX®scan are a 3D sensor in the scanner camera and a positioning mechanism.
During measurement the 3D sensor projects a striped pattern onto the object to be scanned. At the same time a camera records
the striped pattern. The software uses the camera images to calculate a three-dimensional image of the object.
For a complete measurement, the object is positioned at various angles to the 3D sensor using the positioning mechanism of
the scanner. The software then merges the single measurements acquired this way to a closed 3D model of the object.
5.3 Model holder
The model holder is removable and is secured
in position in the orthoX®scan by a magnet.
The model is fixed securely in position on
the removable model holder by a clamping
mechanism with the aid of a sure-grip screw.

6 Placing model in the 3D model scanner orthoX®scan
The model should be placed in the orthoX®scan with the model holder. The model holder is removable and is secured in position
in the unit by a magnet. The model is fixed securely in position on the removable model holder by a clamping mechanism with
the aid of a sure-grip screw.
6.1 Securing model on model holder
Place model in model holder with the anterior teeth facing towards the
sure-grip screw. Secure model on holder by tightening sure-grip screw.
First, scan the maxilla. Then, scan the mandible (see Fig. 5).
6.3 Placing model holder in the orthoX®scan
model scanner
The model holder will only fit on the magnet retention plate in the scanner
if you insert it in the correct position. The anterior teeth of the models on
the holder must always face the camera on the inside of the scanner.
JIf the holder is inserted incorrectly, the holder is loose and
allows a slight tipping movement.
6.2 Placing the upper and the lower model in
occlusion in the model holder
After scanning the upper and the lower model, both models have to be
scanned in occlusion (= vestibular scan). Leave lower model in the model
holder and align upper model in occlusion on lower model. Once both
are correctly positioned, fix the set of models on the model holder using
rubber bands (please cross bands over to secure). Use the lateral hooks on
the model holder to secure the rubber bands.
!
Fix models tightly! Loose models can lead to unusable scan
results. If necessary, insert a wax bite to position models
correctly. The wax bite can stay on the model during scanning.

JThe various color patterns of the upper and lower jaw as well as the vestibular scans make it easier to
recognize an offset.
Check if preview is correct.
If you find the data set not to be good, you can repeat this step by clicking on Articulation (see chapter 7.5).
JThe jaws will be roughly aligned. Minor deviations are allowed and will be corrected during the matching
process. However, if matching does fail, you can repeat the manual aligning.
If you find the data set to be good you can confirm with Continue . The software automatically starts the matching
process. This may take a few moments.
JThe recorded measurements are automatically assembled using special algorithms and put together to STL
data. This process is called matching. The quality settings of STL files are described in chapter 8.1.
14

Once the images have been matched, the finished data set is reloaded into the 3D Viewer and displayed.

Now you can remove excess areas from the model. Use the cutting icons ( or ) to edit the data set.
Select a cutting tool ( oder ), and left-click around the respective area to select it.
To complete the process, click on the right mouse button. The model is cut and can be reset with Undo if necessary.
JThe smaller the data set, the smaller the data volume to merge.
15

After cutting the data set, save the scan data by clicking on Save .
Click on Finalize project to conclude the project .
Clicking on Finalize project will also open a dialog box for dynamic thinning to adapt the size of the STL file (see Fig. 23).

7.5 Aligning maxilla and mandible manually
If the upper and lower jaws are not aligned correctly, use the articulation function to correct the alignment.
Start articulation with the Articulation icon in the tool bar above the 3D Viewer. In the window that opens, you can choose
between automatic aligning or manual aligning using at least three reference points.
Fig. 26: Window for manual alignment
JThe individual scans must be merged to obtain a complete STL data set with both jaws aligned. You need to
determine reference points in the scans for the alignment.
19

Select at least three distinctive reference points by clicking once with the left mouse button on the colored jaw. When
selecting, make sure you use points that can definitely be reflected in the vestibular scan.
To set these points and move the models you will need to use the following shortcuts:
CTRL + left mouse-click: Rotate model
CTRL + right mouse-click: Move model
Left mouse-click: Set points
DEL: Delete last point
