Maestro 3D Easy Dental Scan - User Manual

Introduction to the use of Maestro 3D Easy Dental Scan software

The aim of this document is to introduce the user to the use of the Easy Dental Scan Software, in a simple and quick way. Please read this manual carefully before making use of the Easy Dental Scan Software. Maestro Easy Dental Scan is the software that combines with the line of Maestro 3D dental scanners. The software allows automatic acquisition of the dental objects with one click and creation of 3D surfaces of the acquired data entirely automatic, without any user intervention. The innovative software guarantees exceptional performances, fully exploiting the parallel calculation offered by the most recent multicore and multithreading technologies available on the market.

User Interface

The figure below shows the composition of the user interface.

• 1) Main Toolbar.
• 2) Tree Area.
• 3) Info Area.
• 4) Bottom Area.
• 5) Visualization\Editing Area

Main Toolbar

The main toolbar allows the access to all functionalities of Easy Dental Scan Software.

• 1) New Acquisition - Start a new scan.
• 2) Scanner Status - Activates the window that monitors the hardware scanner status.
• 3) New Group - Adds a new group in the tree. It's possible to move the elements of the tree inside/outside a group by mouse drag and drop.
• 4) Export (Z Axis) - Export the selected item along the Z Axis. You can also select the option Export (Y Axis).
• 5) Postprocess (convert scanned data into a 3D model) - The function is enabled when an item is selected not postprocessed. This operation can take a few minutes to converts the scanned data from the scanner in a triangular geometry.
• 6) Edit - Edit the selected items. This is useful for removing artifacts due to scanning, to remove the putty scanned, for make the holefilling, the decimation, 2D\3D selection edit, etc.
• 7) Import a scanbody from library.
• 8) Align dies on arch - automatic alignment procedure of the stumps.
• 9)
  • Manual align 3-2-1 - Set Fixed item - Set the selected item as fixed in the manual align procedure.
  • Manual align 3-2-1 - Set Floating item - Set the selected item as floating in the manual align procedure.
• 10) Measures - free measures:
  • point-point measures.
  • angle measures.

• 11) CAD - send selected items to the CAD software.
• 12) Views:
  • front view.
  • rear view.
  • right side view.
  • left side view.
  • top view.
  • bottom view.
• 13) Projector status.
  • Power on.
  • Power off.
• 14) Exit.

Bottom Toolbar

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].

Visualization / Editing Area and Info Area

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.

Tree Area

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.

Scan parameters

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.

Advanced Options

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.

WARNING It may happen that with a low number of acquisitions (eg 4-5) for certain models may fail to scan because there is not sufficient overlap geometry between the various shots. In this case it is sufficient to increase the number of acquisitions into the strategy.

• 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.

WARNING Greater is the number of triangles, greater is the size of the STL file. 30000 triangles-> 1,42 MB STL file. 45000 triangles-> 2,14 MB STL file. 250000 triangles-> 11,90 MB STL file.
