Model segmentation

When using the model with plate, the next stage of the model creator is starting the segmentation process. The segmentation is very similar to the traditional technique of model and die fabrication. The wizard has two tabs, PLANES and SETTINGS.

Planes

In the Planes tab there is an image of the model that can be used to toggle the segmentation/ cutting planes. These planes can be toggled on and off by clicking on the grey [A] or green dots [B]. The red dots [C]cannot be changed and are to ensure a cut between stump/die and healthy/adjacent tooth. Click Set all gingiva types to expand the options Gingiva mask [D] and Model analog (preconditioned gingiva [E] and select which one applies to the situation.

Settings

If the settings have been changed, click the Run button.

In Settings tab you can adjust the parameters that affect the model itself.

1 Select printer preset. Right click for advanced options. 2 Select material preset. 3 Automatically Save preset on exit. 4 This is for adjustment width of the cutting plane. See image Cut Width 5 The plate clearance is for depth and circumference cut around the pre-fabricated die pin. See image Plate Clearance 6 The pedestal height.See image Pedestal Height 7 Minimum thickness around the pins. See image Thickness around the Pin 8 Check box for activating/fabricating hollow model. If the Hollow model check box is checked, wall thickness [9]of the hollow model can be adjustments by using the slider for a precise value. 10 Determines how far the preparation margin is extruded vertically towards the bottom plane above the concavity. 11 Adjusts the shape of concavity below the die margin line. See image Shape Parameter 12 Gap width of the gingiva mask. See image Gingiva Mask Gap 13 Model analog support width. See image Implant Support Width 14 Model analog horizontal offset. See image Model analog horizontal offset. 15 Click Run after changing a parameter, in order to re-calculate the model.

• Cut Width

• Plate Clearance

• Pedestal Height

• Thickness around the Pin

• Shape Parameter

• Gingiva Mask Gap

• Implant Support Width

• Model analog horizontal and vertical offset

Moving the plane horizontally left click on the yellow control point b and drag to the correct position. To rotate the plane left click on the green control point a on the labial/ buccal or the lingual side. To angle the plane hold down crtl+shift and left click on the colored plane surface.

In Implant models, you can move the gingiva flat bottom vertically by moving the c plane.

Once this is done the model design is completed, and the output files have been saved in STL format. If you have an antagonist, clicking 'Next' in the wizard will take you to the model design step for the antagonist model.
