The calibration tab is described here: Calibration.

The bottom toolbar is the area of the screen containing a progress bar that is displayed and updated during each computation of the program and the controls for changing the visual settings of the visualization/editing area.

• 1) magnify in [Key PGDown]/magnify out [Key PGUp].
• 2) show/hide trackball.
• 3) reset trackball [Key R].
• 4) parallel projection [Key O], perspective projection [Key P].
• 5) smooth shading [Key S], flat shading [Key F].
• 6) show/hide triangles, edges [Key E], vertices [Key V].

The visualization / editing area is the area of the window in which the models are visualized and all the editing operations are performed.

In the visualization area it is possible to see the models and edit and measure distance between different point.

In order to examine the models displayed in the visualization / editing area camera parameters (position, scale and rotation) can be setted using an instrument called trackball.

The trackball is very simple to use. Just use the Left mouse button dragging to rotate around the model, the mouse wheel to Zoom in / Zoom out and the Right mouse dragging to move (pan) the camera.

The info area of the screen shows the info related to the current item.

The Tree Area contains all the models scanned. The Tree Area organization has a tree. The use of groups allows you to keep an ordering of the models scanned. To select a model from the Tree Area just click on it with the left mouse button. The models selected will be displayed on Visualization Area. To select more models click by holding down the CTRL\SHIFT key.

The Tree Area can contain the following elements:

	Stump
	Upper Jaw
	Lower Jaw
	Upper\Lower Gingiva
	Upper\Lower Waxup
	Maxillary\Mandibular Relationship
	Rangemap
	Group

For each of these elements there is associated a set of operations accessible via enabled icons in the Main Toolbar. These allow the user to access the main functions of the software.

By accessing the drop-down menu as shown in the following figure, you can import into the tree the STL file.

Some examples of target objects:

• Maxillary and Mandibular relationship

• Upper-Lower Jaw

• Other examples of dental arch

• Impression

• Stumps

To start a new acquisition just press New acquisition in the Main Toolbar.

Through this window you can choose the type of object to be scanned

Just click Advanced Options to access to advanced options for scanning.

If you choose to scan an arch, gum, waxup or impression, you can choose if it's an upper or lower element.

In questa parte della finestra si possono definire i parametri della scansione.

• Scanning Strategy:

It's possible to choose a scanning strategy. The strategies are available depending on whether the tilt module is activated or not. If you do not have the Tilt module active, all of the strategies shown only work with the rotary axis.

• Faces (triangles):

This number defines the number of triangles you want in your final model. The figure below shows the same model with 45000, 10000 and 2500 triangles. The precision and accuracy in the 3 models is equivalent. Among the 3 models changes the number of triangles that approximate the surface geometry. The system acquires always at max precision and max accurancy. Only after obtaining the final three-dimensional model at max number of triangles, it is decimated to obtain the desired number of triangles. Is also possible to decimate the model later.

Recommended values:

• Height of interest:

This param allows you to choose the height of interest of the model, (this height value is measured starting from top to bottom).

First picture (from left to right) shows the model of a stump where the height of interest parameter is disabled and then the stump is acquired entirely including the adhesive putty support that sustains it. Subsequent images display the same stump with the height of interest parameter set at 20 mm and 15 mm respectively (as can be seen the adhesive putty support is automatically removed).

It is important to remember that, in order to make the best use of this parameter, the model (arc, one or more stumps, etc...) must be placed perpendicular to the surface of the rotary table.

In any case, you can always remove the not interesting geometry, at any time, by editing the model.

• Texture Color Superimposition:

This requires the Texture Color Superimposition module active. The activation is carried out through a software license. This is useful to obtain models with a RGB color texture or grey scale color texture. For example it helps create very accurate margin lines as marked on the model.

• Improve alignment:

If this option is checked, the software will use a procedure that will improve the alignment of the various acquisitions. This is not recommended if you use strategies with numerous acquisitions, (more than 20). This is because the time and the memory taken could be very high.

• Close base:

If this option is checked, the software close the bottom base of the model automatically.

• Postprocessing (convert the data acquired in a 3D model):

If this option is checked, the system automatically postprocessing the data acquired and it builds the triangular geometry surface. If it is not checked the data will be not postprocessed. It is possible postprocess the data acquired later.

• Good (fast): this option is recommended.
• Best (slow): this option take more computation time and make a 3D models with more details.

• Play sound after scan:

It's possible to choose a *.wav file to play after the scan and after the postprocessing.

• Turn off the system after the scan:

Turn off the system after the end of the scan.

This window shows the progress of the scanning phase. This may take a few seconds or a few minutes depending on the strategy chosen. In the window on the left shows the 2D image acquisition and 3D image on the right.

After this operation, if the the option "Postprocessing" was checked the software automatically generates the surface of the model from the acquired points, and adds to the Tree Area a new element. Then selecting it in the Tree Area, the model is displayed into the Visualization Area.

If the option "Postprocessing" was not checked, the software adds to the Tree Area a new element with a greyscale icon. Before you can perform any operation of this model is necessary to postprocess the data acquired.

In the following images the correct positioning of the models on the rotary table is showed. The image below shows an arch correctly positioned on the rotary table. The arch should be placed at the center of rotary table supported by the putty or any other adhesive that keeps it well anchored to the table.

The arch should be parallel to the surface and should not be tilted.

It is possible to put on the rotary table of the scanner more stumps simultaneously. See the following pictures to observe the proper placement of stumps. After the scanning process, the software automatically recognizes and separates the individual stumps, adding an item in the Tree Area for each acquired stump. The pictures below show how to correctly place the stumps on the rotary table of the scanner. The scanner may be equipped with a multidie plate of 8 teeth.

The numbering (1..8) on the plate meets the numbering of the elements added to the Tree Area only if the plate is placed in front of the scanner. When working with more than a stump it is absolutely necessary that adhesive putties sustaining stumps and the body of each stumps will be separated at least some millimeters from each other. In this way the scanning software is able to recognize each stump, see the correct stumps position in the picture below:

An example of incorrect positioning:

The following image shows the window for managing the scanning strategies.

• 1) Scanning group: MMR, Arch, Stumps, Impression.
• 2) Strategy name.
• 3)
  • New Strategy.
  • Save current Strategy.
  • Delete current Strategy.
• 4) Add tilt command (before adding the command selects the rotation degrees).
• 5) Add rotation command (before adding the command selects the rotation degrees).
• 6) Commands:
  • Clear all commands.
  • Delete selected command.
  • Add tilt home position command.
  • Add rotation home position command.
  • Add an alignment group.
  • Add a single acquisition.
  • Start the strategy simulation.
• 7) add a batch acquisition. (before adding the command select the number of rotary table steps of the rotary Axis).

The registration of stumps is totally automatic and it allows to replace the low resolution stumps, acquired with the arch, by the high resolution stumps acquired without the arch.

Select into the Tree Area the arch with the stumps (which are to be replaced) and click the button

After the arch is displayed in the Visualization Area with a constrained view so that it can be inspected only from above.

• 1) To add the stumps\scan body to substitute, select these from tree area and press the buttons.
• 2) Options:
  • if replace stumps is checked, the high resolutions of the single stump will be replaced with the lower resolutions stump scanned with the arch. This is recommended if you need to work with a dental cad software. If not select this option the stump will be only aligned.
  • If this option is checked the software make a backup copy of the data.
• 3) Choose the kind of registration procedure (1 point registration or 2D selection registration).
• 4) Preview area of the stumps.

After having selected and added the stumps, press the SHIFT key and left mouse button double click with the left mouse button over the center of the head of the low resolution stumps to indicate the position where every stump must be registered.

By double clicking over the head of the stumps, it is added to the Visualization Area a sphere (called marker) associated with a number. Color and number, as shown in the picture, these are associated with the right stump.

Before to proceed with the registration, please make sure that each marker is associated with the right stump. To proced with the registration press the button .

A progress bar placed in the Bottom Toolbar will indicate the progress of the registration process.

At the end of the registration process the result of the registration is displayed in the Visualization Area, where low resolution stumps have been replaced with high resolution stumps. If you are satisfied with the result press the button to finish and save the registration obtained or press the previous button to return to previous step.

If one or more stumps are not correct aligned, press the close button near the marker and then after having completed this task you can re-register only those stumps.

If the registration is not satisfactory, please verify that markers have been placed in the correct position as explained previously (in the center of the head of each stump and in the correct order).

With the manual registration process, is possible to align any pair of models. To align two models. For example useful to align a stump on an arch or an arch or bite with a antagonists reference model.

To align the two models need to select the fixed model (example maxillary mandibular relationship) and the floating model (example arch). The next image shows the manual alignment window.

To align the floating object over the fixed object you have to add some points in the fixed model that appears to the left of the screen and the same points should be added to the floating object in the right of the window. You must add at least 3 points on each model.

• 1) Clear fixed or floating point.
• 2) Fine alignment. Improves the initial alignment given by the points entered by the user.
• 3) In case you are align a stump over an arch you can check this option to replace the geometry of the high resolution stump on the lower resolution stump of the arch.
• 4) Preview area where are showed the fixed and floating model.
• 5) Alignment result.

With this button you can access the editing features of the rectangular selection. The image below shows the filter window.

Holding down the SHIFT key and the left mouse button you can draw a rectangular selection area. The area of ​​the selected geometry will appear colored red.

This scanning wizard helps the user to make all necessary scans and alignments to obtain a complete case to work into Ortho Studio software.

The following image shows the first step of the scan. In this phase you can scan maxillary and mandibular relationship. In this window you can change the scanning settings and the scanning strategy.

The following image shows the result of the previous scan, the maxillary and mandibular relationship. Now the user can scan the lower arch.

The following image shows the result of the previous scan, the lower arch. Now the user can scan the upper arch.

Now it's possible to perform the alignment of the upper and lower arch respect to the relationship.

The procedure of alignment is the Manual 3 2 1 Alignment. After that the scanning software send the correct data to the Ortho Studio software.

This scanning wizard helps the user to make all necessary scans and alignments to obtain a complete case to work into all dental cad integrated with Maestro 3D Scanner. The following image shows an example of a wizard step of the scan. In this window you can change the scanning settings and the scanning strategy.

To integrate the scanner with the exocad software you need to edit the file \exocad-folder-installation\DentalDB\config\defaultsettings-db.xml as shown in the figure below.

From the menu of the main window, tap on the enter ? -> About.... The image below shows the About window of the Software. In this window there is the dongle serial (tap on the adjacent key to copy it in the clipboard) and the version number Build

• 1) Dongle Serial.
• 2) Copy Dongle Serial into Clipboard.
• 3) Software Build Release version.

From the main menu tap on the entry File -> Check for updates.

From the main menu tap on the entry File and tap on the entry Activate for each available module. Here, a message that will show if the module is active will appear; otherwise a window to import the license file that will activate the module in case it is not, will open.

Just make a copy of the folder where the software saves all scans. By default the folder is c:\MaestroData\.

If the software is very slow on startup, the cause is probably that the save folder (by default c:\MaestroData\) contains many scans. Just empty the folder or delete it completely and restart the software.

Edit the file application.settings.xml which is located in the installation folder of the software and change the string MaestroFolderData="c://MaestroData". To restore the settings with default value, just delete the file application.settings.xml and restart the software.

Yes it's possible but in order to improve scanning of metal parts you must use a scanning spray. In the market there are a lot spray but we advise the [Vacalon quickcheck spray].
