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 create virtual bases, show the occlusion inspection between maxillary and mandibular arcs, measure distance between teeth and to perform virtual setup.

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 Case. In particular the info about Surgery, Doctor and Patient are displayed, also with the Case ID.

Create a New Case and Open an Existing Case

Create a New Case

To create a new case press the New Case button located in the main toolbar. The process of creating a new case consists in the following steps:

• specify the Surgery data (optional)
• specify the Doctor data (optional)
• specify the Patient data (optional)
• specify the relationship between Surgery, Doctor and Patient (optional)
• choose maxillary and mandibular models (required)

To create a new Surgery press the Add new surgery button, located in the left side of the screen. After filling the fields of the form that appears in the main side of the screen specifying the data of the Surgery, press the Insert button to add the new Surgery to the database or the Clear button to clear the fields of the form.

In the same way it is possible to create a new doctor pressing the Add new doctor button and to create a new patient pressing the Add new patient button. In order to define a Case it is necessary to press the Select patient button located in the left side of the screen.

In the main side of the screen now it is possible to make the relationship between Surgery, Doctor and Patient. The first half of the main screen area allows to make the relationships between Surgery, Doctor and Patient (see picture below).

Select the surgery from combobox. The Delete button allows to delete the surgery currently selected. Please note that when pressing the Delete button the Surgery definition is phisically removed from the Database of the Surgeries.

When the list of the Doctors associated to a given Surgery is empty and in general when it is necessary to add a new Doctor to the Surgery previously selected, it is possible to select a Doctor in Other doctors combobox and then pressing the Add button. The Delete button located nearby to the Other doctors combobox allows to remove the definition of a Doctor from the Database of Doctors.

Select a Doctor from combobox. This allows to select one of the Doctors associated to the Surgery. The Delete button located nearby to the Doctor section allows to remove a Doctor from the Doctors of a Surgery without deleting the doctor from the Database of Doctors.

When the list of the Patients associated to a given Doctor is empty and in general when it is necessary to add a new Patient to the Doctor, it is possible to select a Patient in Other patients combobox and then press the Add button. The Delete button located nearby to the Other patients combobox allows to remove the definition of a Patient from the Database of Patients.

Select one of the Patients associated to the Doctor. The Delete button located nearby to the Patient section allows to remove a Patient from the Patients of a Doctor without deleting the patient by the Database of Patients.

Please note that in the second half of the screen main area it is possible to modify the fields of the Surgery, Doctor and Patient previously added.

Pressing the Next button located in the lower right corner of the window allows to proceed in the definition of the case.

The task of choosing maxillary and mandibular models can be accomplished in three distinct way, see the image below.

• choosing a model by the tree of the Maestro Data (this is the folder in which the models acquired by Maestro 3D Dental Scanner are placed by default).
• importing a model by an external folder using the Open files from disk button (the allowed format for the models to import is the STL file format).
• importing a model by an external folder using the Import Ortho files from disk button (the allowed format for the models to import is the ortho file format).
• start the acquisition with Maestro 3D Dental Scanner.

Open an Existing Case

To open an existing case click on the Open case button located in the main toolbar. In the treeview it is now possible to select an existing case. To see all the cases of a given patient press the Select patient button located in the left side of the screen. In this phase it is possible to change the properties of a case, changing the Surgery, Doctor and Patient info and adding a new Surgery, Doctor and Patient. Also note that it is possible to move an unknown case or a case of a given Patient in a case of another Patient simply locating the case in tree and dragging it from the starting folder to the destination folder.

Pressing the Next button located in the lower right corner of the window it is possible to proceed with the next operation. Pressing the Cancel button break the process of opening an existing case.

The image below shows the process of opening an existing case.

Changing the Local Origo

In order to change the Local Origo for the maxillary and mandibular models, press the Change Local Origo button.

In the editing area appears a Manipulator (see image below). The center of the manipulator represents the origin of the coordinate system, the red arrow represents the X axis, the green arrow represents the Y axis and blue arrow represents the Z axis of the coordinate system. Using the Left mouse button it is possible to translate the Manipulator (dragging the arrows) or rotate the manipulator (dragging the circles). These operations allows to change the coordinate system of the models. Pressing the [[image:next.png] Next button located in the lower right corner of the editing area allows to move the maxillary and mandibular models in the new reference coordinate system. In order to apply the changes to the models, please remember to press the Save case button located in the main toolbar.

Virtual Base Creation

In order to add the virtual base for the maxillary and mandibular models, press the Add virtual base button. First step to perform when doing virtual base editing, it's to define a trimming line in order to remove the unimportant areas of model. It's possible to define trimming line simultaneusly for both models. After defining trimming line, software automatically detect area to remove.

TIPS: SHIFT + click or drag with left mouse button to add a point of the spline.

The second step is the editing operations on virtual bases. It's possible to choose several base types, in particular it's possible to choose between ABO, Parallel, Tweed and Ricketts models. It's also possible to perform simultaneusly several several editing operations for virtual base:

A: changing base border shape: dragging points located at base border it's possible to change the shape of the border itself. It's also possible to add/remove points using shift + left mouse double click. It's also possible to draw the base border just using the shift + left mouse button dragging near to the base border. Dragging the arrows located at base border it's possible to move the border up and down.

B: changing base shape: dragging points and arrows located at corners of virtual base it's possible to change the shape of the virtual base (for example it's possible to change the width and the length of bases). During all the editing operations, constraints that exists between angles/sides of base are preserved.

C: changing base height: dragging the arrow positioned at base bottom it's possible to change the height of bases (this option it's disabled for ABO bases). All operations concerning virtual base editing process are performed with Shift + left mouse button dragging (Shift + left mouse double click to add remove points to base border). Using the “Symmetrical changes” checkbox, editing will be performed simultaneusly on both bases. After finishing editing process just press Next button in order to finalize the editing procedure and merge the defined bases with maxillary and mandibular models.

TIPS: SHIFT + double-click / drag with left mouse button to add/remove points to base border.

Stitching between base and model it's more smooth and the transition between arch and base it's smoother.

Analysis and Measures

Occlusion Inspection

To see and analyze the occlusion inspection between maxillary and mandibular arcs just press the Occlusion inspection button. After the computation each point of the surface of an arch is painted with a color representing the distance by the opposite arch surface. In the right side of the editing area is located a legend that explain the meaning of the colors. It is also possible double clicking on the model to know the exact distance value for this point. Please note that it is possible query for the value only for an area of the model with a color assigned.

The following images shows the occlusion inspection visualized on both the arcs. To activate this visualization press the Open mouth button.

The following image shows the occlusion inspection visualized on the maxillary arch. To activate this visualization press the Show Maxillary button.

The following image shows the occlusion inspection visualize on the maxillary arch. To activate this visualization press the Show Mandibular button.

Cross Section

As for the process of the cutting line definition, it is possible to add, remove or modify the position of the points. For each line segment defined by two consecutive points the current length of the segment is showed. On the left side of the screen the total length and the average length of the segments are showed too. Using the Undo button and the Redo button it is possible Undo / Redo all the operations performed. It is also possible to clear the measure using the [[image::Polyline.delete.png]] Reset button. In order to save the measures, after pressing the [[image::next.png] Next button, please remember to press the Save case button located in the main toolbar.

Arch Length

In order to perform the analisys of the arch length, select the arch to inspect using the Show Maxillary button button or the Show Mandibular button and then press the measures button.

TIPS: double-click with left mouse button to add a point of the spline to compute the arch length.

Put the points in the following order to define a correct spline. It's possible to add more than 3 points.

TIPS: double-click with left mouse button to add a point.

Virtual Setup

With this feature, you can make a setup of both jaws and create all the models needed to complete the treatment. It's possible to add the custom attachments and the label 3D.

Tooth Segmentation

Detect Margin

In order to perform the tooth segmentation, select the arch to segment using the Show Maxillary button or the Show Mandibular button and then press the Tooth Segmentation button. Before this it's necessary complete the measurement of individual teeth.

The first step is identify the margin of the tooth. See the image below.

To identify the margin of the tooth, double-click with the mouse near the margin to add a new control point as showed below:

Every two points entered by the user, the software makes a line near on the margin of the tooth. Usually is enough 4 clicks to draw a margin, as shown in figure. If the autocomplition of the line is not correct, press CTRL + Z or press button and try to add a new click in a different position example closer to the previous point.

TIPS: To add a point between two consecutive points, hold double-click near the edge of the two points. To remove a point, double-click over it. To move a point, drag over it.

Cutting Line

In order to perform the cutting line of the tooth segmentation, select the arch to segment using the Show Maxillary button or the Show Mandibular button and then press the Cutting line button. Before this it's necessary complete the previous step of Detec Margin. See the image below:

TIPS: To add a point between two consecutive points, hold double-click near the edge of the two points. To remove a point, double-click over it. To move a point, drag over it. Click with center mouse button to change the rotation center of the trackball.

Tooth Local Origo

In order to perform the local origo of each tooth, select the arch to segment using the Show Maxillary button or the Show Mandibular button and then press the Change local origo button. Before this it's necessary complete the previous step of Cutting Line. See the image below:

To change the local origo of a tooth, double click over the tooth and use the manipulator to change the origo. When you change the local origo the virtual root of the tooth change direction. Use the left toolbox to change the root dimension when a tooth is selected. See the image below:

TIPS: click with center mouse button to change the rotation center of the trackball.

Virtual Setup

In order to perform the virtual setup, press the Virtual Setup button.

In this step you can translate and rotate the teeth in order to obtain the desired final position. To select a tooth, click with left mouse button over a tooth.

TIPS: SHIFT + left mouse button to translate the teeth selected. CTRL + left mouse button to rotate. Click with the middle mouse button to change the center of rotation of the trackball.

Take a look to the GUI on the left of the screen that allows to access to all the functionalities of the Virtual Setup.

Layers

The layers are the steps that are useful to work with some groups of teeth in different period, i.e.:

you can move the posterior teeth and build a layer1.

than you can move the anterior teeth and build a layer2.

In this way when the software builds a set of virtual models, it is obtained:

Original model
virtual model (1)	Clear aligner 1
virtual model (2)	Clear aligner 2
...	...
Layer1	Clear aligner L1
virtual model (k)	Clear aligner k
virtual model (k+1)	Clear aligner k+1
Layer2	Clear aligner L2

So the first set of aligners don't move all teeth but only the posterior teeth. Only after some weeks, when you start to the layer1 you are ready to move the the anterior teeth.

It's possible to work only with the last layer. If you select a different layer, all functionalities will be disabled.
