In this page will be followed and explained the wizard for scanning 2 models in occlusion with 3 dies (2 upper and 1 lower) using Open Technologies' Dynamic Articulation Module.

The Dynamic Articulation Module allows the user to transfer the mastication position realized in the laboratory with a real articulator into its Exocad virtual equivalent. The available articulators in Exocad, for which we can provide the exact positioning are Artex, Protarevo Kavo, Sam, Bioart A7 and Denar by Whipmix.

When the Dynamic Articulation Module gets enabled, the user is provided with a set of 4 Mounting Plates and a Recalibration Object. See Accessories- Dynamic Articulation Module.

Before using the Module for the first time it is necessary to calibrate the axis of the scanner to work accordingly to the occlusion simulation. Learn how to calibrate at the page Calibrate your scanner.

THIS IS AN ADDITIONAL OPEN TECHNOLOGIES LICENSE MODULE: ASK YOUR DEALER HOW TO GET IT!!

Project definition starting from Exocad

To create this project in Exocad, click on the DentalDB icon on your desktop. The project manager will open.

Fill in the project information, the kind of restoration that needs to be designed and the extra parameters. For this kind of project make sure that the Scan Mode is set on one of the available virtual Articulators of Exocad; choose between:

  • Two stone models in Articulator A for Artex
  • Two stone models in Articulator S for Sam or Adesso
  • Two stone models in Articulator P for Protarevo- Kavo
  • Two stone models in Articulator B for Bioart's A7
  • Two stone models in Articulator D for Denar by Whipmix

For further information on how to create projects in Exocad, visit the specific page on the Exocad Wiki!

Here is the project definition for our demo project; we have used the Articulator Protarevo by Kavo:

Prj-exo-dynamic.gif

Once the project has been defined just click OPT in the Actions section to launch the scanning software.
The first thing the scanning software shows is the project created in Exocad. Check if the articulator selection is correct, if so click the Accept Button Ok.png.

Prj-check-dynamic.gif

Project definition starting from ScanWay

All projects can be defined in the scanning software as well, regardless the CAD that will be later on used to design.

Launch the scanning software double-clicking on the ScanWay icon on your desktop. The Welcome Page will open; to create the project click on the first icon.

NewPrjIcon.png

For detailed information on how to define a project visit the specific page: Create a New Project.

For this project, take particular care in the articulator selection. If the articulator gets wrongly defined, the virtual articulation won't be realistic and useful.
Also, remember to set Exocad as CAD platform, since this module is specifically designed to work for Exocad's Virtual Articulator.

Here is the definition of our demo project:

Prj-definition-dynamic.gif

Both the project definitions described lead to the same wizard, which will be now followed step by step.

Step 1: Articulator Scanning

The first step of any project that has been set to have both jaws, is the Articulator Scan.

In this specific case, the Articulator has to be scanned. The scanned articulator needs to match the one selected in the project definition.
We suggest scanning the articulator tilting it backward, to get as much information as possible. This is just a suggestion as not all articulators can be tilted.

Articulator positions.png

In the live view of the scanning interface, you can actually see that if the articulator is standing straight it will be difficult to acquire the occlusion properly.

Live arti posizioni.png

Once the articulator has been placed in the scanner, the scan can be started with the Scan ButtonScanAction.png. Once the scan is finished the result will be shown.

Arti-dynamic-steps.png

For further information on the other available functions check the Scan Interface page.

Click NextAction.png to access the second step of the wizard.

Step 2: Lower Model

The second step of any project that has been set to have both jaws, is the Lower Model Scan. All steps, except for the articulator one, include two sub-steps: the actual scan and the edit of the acquired image.

Scan Step

Place the lower model on the split-cast base matching the selected articulator; for our demo case we used the Protarevo- Kavo Splitcast base.

Basetta protar.jpg

Click the Scan ButtonScanAction.png. Once the scan is finished the result will be shown.

Lower-dynamic-steps.png

Click NextAction.png to access the second part of the Lower model step.

Edit Step

This step allows to edit the acquired image; for detailed information on all the available options in this step visit the Edit Tools page.

The image at this step can be both edited or trimmed. At this stage, it is actually important not to edit too much the image or cutting big chunks of information, since it would make it more difficult for the software to calculate the automatic alignment of the object to its reference.

In this particular case, since the model is mounted in the articulator, it's not scanned on a perfectly horizontal plane, so to trim it faster we used the polygonal selection tool.

Edit-lower.gif

When you are satisfied with the result click NextAction.png to access the next wizard step.

Step 3: Upper Model

The upper model Scan, like the lower model, requires the user to undergo two steps.

Scan Step

Place the upper model on the split-cast base matching the selected articulator and click the Scan ButtonScanAction.png. Once the scan is finished the result will be shown.

Upper-dynamic-steps.png

Click NextAction.png to access the edit step for the Upper model.

Edit Step

The upper model can still be edited as shown for the lower model. This time, we will edit the image using a different selection tool.

Edit-upper-dynamic.gif

Step 4: Dies Scan

The steps necessary to successfully scan the dies vary depending on the scanning method that the user chooses to apply: the use of the multi-die plate or the custom set-up.

With Multidie

This method is applied by default by the software. It implies that the user will put the dies on the multi-die plate in the position shown by the software, which will make each die immediately recognizable and cut the steps of the wizard.

Definition
As mentioned, the position of the dies in the multi-die plate is pre-established by the software.

The multidie order is based on the Universal tooth numbering, starting from the last element of the first quadrant and following in a clockwise order. Therefore the die that needs to be placed in the central element will always be the one closest to the last element of the first quadrant.
If there are more than 9 dies, a second definition step will be shown.

Wizard-multidie-def.png

Click NextAction.png to access the multidie scan step.

Scan
The multi-die scan interface is similar to the other steps we just explained, except for the multi-die reference that is kept as a reminder on the right side of the window, under the live view.
To proceed click the Scan ButtonScanAction.png. Once the scan is finished the result will be shown.

Multidie-steps.png

Click NextAction.png to access the edit step for the multidie scan.

Edit
The edit step offers the same tools we saw in previous steps. In this case, more than one tool may need to be applied.

Edit-multidie.gif

When you are satisfied with the result click NextAction.png to access the next wizard step.

Alignment
After being edited the dies get aligned to their references. The result is then shown on the monitor. To learn how to change, fix or redo the alignment check the Alignment Interface page.

Dies-autoalign.gif

Custom Set-Up (Without Multidie)

The user can also decide to scan the dies in a custom order, for instance, if he needs to scan the dies on the model base. To access the custom set- up definition, click on the CustomSetupAction.png icon when the software presents the multi-die definition.

Custom-setup-dies.png

Definition
The software proposes by default a unique scan group which means that, if not defined otherwise, the software will ask the user to scan all the stumps together. In this case, I have created a second scan group, to divide the scan of the upper dies from the scan of the lower dies. Click NextAction.png to access the scan steps.

Def stumps.png

Scan
Depending on the number of scan groups created, the software will propose one or more scanning steps.

First, the software requires the user to insert the dies in the scanner and acquire the items of the first group.
As a reminder, it marks the items to be scanned together on the right of the window, under the live view.

Then it will ask the user to insert the item selected for the second group. Since the second scan is an individual die, there will be no reminder on the right. Click NextAction.png to continue.

Dies-steps.png

Dies Identification
When a scan group has more than one item, the user will be asked to separate each die from the others to correctly identify it.
This step occurs in between the scanning steps. To learn more about the identification of the dies visit the Scan Interface page. Click NextAction.png to continue.

Extract 24 26.gif

Edit
If the scan group is formed by one individual die, there will be no identification step. Instead, the edit step will be presented. Click NextAction.png to continue.
Alignment
After being edited or identified the dies get aligned to their references. The result is then shown on the monitor. To learn how to change, fix or redo the alignment check the Alignment Interface page.

Step 5: Healthy and Pontics

At this stage, the project has been scanned, unless the user wants to rescan the healthy and pontics. This step is, in fact, a result of the scan of the scanned reference model, trimmed to exclude the parts that have been scanned individually (in this case, the dies). It sometimes happens that in the first model scan, the contact points on the healthy are not correctly recognized, which would require the user to rescan the model. Otherwise, just click NextAction.png to continue.

Healty-both.png

The software will then propose a further edit step to allow the user to modify the healthy image. Proceed in the edit step as previously explained.

Step 6: Mesh Generation and Export

At this point, the software immediately starts mesh generation. The meshes can be edited and exported individually or as a unique image. To learn more about mesh editing visit our Mesh Tools page.

Click on the Export Button ExportToCadAction.png to export to CAD.

Wizard-interface.PNG

If the project has been started from Exocad, the CAD will automatically open and the design can be started immediately. Otherwise, the software will ask the user how to export the file.
Since Exocad has been selected in ScanWay's project definition, the software will ask the user to find the folder containing the DentalProject file for this job.
