In this page will be followed and explained the wizard for scanning 2 quadrant models in occlusion with 3 dies using the Open Technologies Quadrant Module.

This module allows to scan quadrant models, with up to 4 stumps, in a 2-steps defined project cutting in half the scanning time.

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

To create this project in Exocad, click on the DentalDB icon in 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 '''Two stone models in occlusion''', the type of model will be specified later in the scanning software to trigger the correct wizard.

For further information on how to create projects in Exocad, visit the specific page on the [http://wiki.exocad.com/wiki/index.php?title=DentalDB_Module Exocad Wiki!]

Here is the project definition for our demo project:

[[File:prj-definition-exo-quadrant.gif]]

Once the project has been defined just click '''OPT''' in the Actions section to launch the scanning software. <br />The first thing the scanning software shows is the project created in Exocad.

In order to activate the correct wizard, click on the '''Model Type''' icon and select the {{Inline button|quadrantModel.png}} option.<br /> Click the Accept button {{Inline button|ok.png}} to save the changes and start the project.

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 [[Splash|Welcome Page]] will open; to create the project click on the first icon.

Here is the definition of our demo project:

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

In this case, for articulator, is ment the quadrant tray occlusor, which can be scanned directly on the normal model holder.<br />The user can decide freely how to place the occlusor on the model holder, here are our suggestions.

Once the objects have been placed in the scanner (either the articulator or the models one on top of the other), the scan can be started with the '''Scan Button'''{{Inline button|scanAction.png}}. Once the scan is finished the result will be shown.

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

Click {{Inline button|nextAction.png}} to access the second step of the wizard.

This step develops in the usual phases.

For this step, all the elements need to be positioned as marked by the software in the Quadrant holder.<br />

Click the '''Scan Button'''{{Inline button|scanAction.png}} to start the scan. Once the scan is finished the result will be shown.

Click {{Inline button|nextAction.png}} to access the edit step.

In this case, the image has been trimmed using the base cut tool and clincing on the apply button.

'''BE CAREFUL NOT TO TRIM TOO MUCH, AS TO DO SO THE SOFTWARE MIGHT HAVE ISSUES DURING THE AUTOMATIC ALIGNMENT'''

[[File:edit-quad.gif]]

Click {{Inline button|nextAction.png}} to access the alignment phase.

As for all scanned items, the software tries to allign all the images to their reference. In this case the reference for all the scanned items is the articulator scan.

At the end of the alingment the results are shown. To learn more on the automatic alignment and the manual procedure visit our [[Align|Alignment Interface]] page.

Click {{Inline button|nextAction.png}} to access the last step of the wizard.

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|Mesh Tools]] page.

Click on the Export Button {{Inline button|exportToCadAction.png}} to export to CAD.

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.
