Model Design: Models without Plate

When using the model without plate, the next step of the model creator is building the model and separate dies which fit within the model. The wizard is now in the model design and has three tabs, DIES, MASKS and SETTINGS.


The Dies tab parameters are:

Plateless model 3.1 a.png
  • 1 The height of the key pin. 250 1.ModelDieWithBoreProcessorControl.gif
  • 2 Determines how far the preparation margin is extruded vertically towards the bottom plane above the concavity. 250 2.ModelDieWithBoreProcessorControl.gif
  • 3 Width of the bottom seating area of the dies. 250 3.ModelDieWithBoreProcessorControl.ModelSeatingAreaWidth.gif
  • 4 Defines the shape of the die, set 0 ° for a straight die or > 0 ° for a tapered die.250 4.ModelDieWithBoreProcessorControl.ModelDieShaftTaperAngle.gif
  • 5 Determines the height limit of the taper. 250 5.ModelDieWithBoreProcessorControl.ModelDieShaftTaperHeightLimit.gif

  • 6 Excludes the pins from the dies. 250 6.ModelDieWithBoreProcessorControl.ModelOmitDiePin.gif
  • 7 Remove or Add the concavity below the margin preparation. 250 7.ModelDieWithBoreProcessorControl.ModelConcavity.gif
  • 8 Parallelizes the die bottom to the model base. 250 8.ModelDieWithBoreProcessorControl.ModelTiltedDieIsSkewed.gif
  • 9Uniform die insertion direction. 250 9.ModelDieWithBoreProcessorControl.UniformDieAngle.gif
  • 10 Reset the insertion axis of the dies.

  • 11 Set insertion axis of all the dies from the view into a common direction.

  • 12 Click Run after changing a parameter, in order to re-calculate the model.

  • Once the calculation has finished, the output .stl files will be saved in the Project Directory.

    TipAs an end user of the software, you shouldn't have to fiddle with the parameters at all. You should get optimal results using the default presets provided by your system integrator, or using the presets provided by the supplier of the manufacturing equipment or production center. If not, please let your system integrator and/or manufacturing equipment vendor know!


    Gingiva MaskWatch the video tutorial: Gingiva Mask

    The Masks parameters are:

    • 1 Minimum thickness of the gingiva mask.

    250 1.ModelDieWithBoreProcessorControlb.gif

    • 2 Spacing between the gingiva mask and the model base.

    • 4 Check box to create retention nubs.

    250 4.ModelDieWithBoreProcessorControl.ModelGingivaMaskRetentionBallDiameterCheckbox.gif

    • 5 Determines the diameter of the retention nubs.

    250 5.ModelDieWithBoreProcessorControl.ModelGingivaMaskRetentionBallDiameter.gif

    • 6 Determines the space between the retention nubs. A larger value will reduce the amount of nubs.

    • 7 Click Add to draw the margin of the gingiva mask.

    • 8 Click Remove to delete the existing gingiva mask to create a new one.

    • 9 Click Run after changing a parameter, in order to re-calculate the model.

    TipIn case the die has an extreme insertion direction, this may affect the final outcome as shown in [A]. In order to avoid it, please change the insertion direction of the die [B] or redraw the gingiva avoiding the problematic area [C]. Note that for lab analogs with an extreme insertion direction redrawing the gingiva is the only option.

    Flat Mask

    Flat MaskWatch the video tutorial: Flat Mask

    • To create a flat gingiva mask, select as Model Type Plateless model [1] and then below it gingiva masks flat [2].

    Flat Mask-01 3.1.png

    • Once you are in the step "Plateless Model Design’’ Tab ‘’ MASKS’’, select Add [3] and click on the Jaw [4] you want to create the Mask.

    Flat Mask-02 3.1.png

    • After clicking, you will see automatically the jaw from an occlusal view. Click [5] to draw the area you would like to create a flat mask.

    Flat Mask-03 3.1.png

    • Double-click to generate the flat mask [6].

    Flat Mask-04 3.1.png

    • The flat mask [7] can be editable using the control points [A], lines [B], and mask inner area [C]. These are editable with hotkeys as described below. After editing the flat mask as desired, click Run [8] to apply.

    Flat Mask-05 3.1.png

    HotkeyHold click + drag - move the mask in all directions
    Shift + click on the inner mask - move the mask on the z axis
    Ctrl +click on the mask inner area - rotate the mask
    Click on the top or bottom edge/line of the mask - change the height of the mask
    Ctrl+ click on the control point - also change the height of the mask
    Ctrl + click on the top or bottom edge/line of the mask - add another control point
    Double click on the top or bottom edge/line of the mask - add another control point
    Left click + hold + right click simultaneously on the control point - remove control point
    Click + del on the control point -remove control point
    Ctrl + shift + click on the inner area - tilt the mask
    • To continue click Next [9].

    The Settings tab parameters are:

    Plateless Model Settings 3.1 1.png
  • 1 Select printer preset. Right click for advanced options.

  • 2 Select material preset.

  • 3 Automatically Save preset on exit.

  • 4 Spacing between a die and the model base in horizontal (x and y) direction.
  • 250 1.ModelDieWithBoreProcessorControlS.gif

  • 5 Spacing between a die and the model base in vertical (z) direction.
  • 250 2.ModelDieWithBoreProcessorControlS.gif

  • 6 The mounted base height. See image Pedestal Height
  • 250 3.ModelDieWithBoreProcessorControlS.gif

  • 7 Check box for activating/deactivating the ditch.
  • 250 4.ModelDieWithBoreProcessorControl.ModelDitchWidthCheckbox.gif

  • 8 Determines the width of the ditch around the stump.
  • 250 5.ModelDieWithBoreProcessorControl.ModelDitchWidth.gif

  • 9 Determines the average depth of the ditch around the stumps. Since the bottom of the ditches is made almost flat, the depth cannot be met exactly everywhere.
  • Plateless Model Settings 3.1 2.png

    250 6.ModelDieWithBoreProcessorControl.ModelDitchDepthAvg.gif

  • 10 Determines the average height of the ditch around the stumps.
  • 250 7.ModelDieWithBoreProcessorControl.ModelDitchHeightAvg.gif

  • 11 Adds indentations in the base of the model exposing the pins for easier removal. See image Add pin Grooves
  • 250 8.ModelDieWithBoreProcessorControl.ModelBottomPinGrooveDepthCheckbox.gif

  • 12 Determines the width (i.e. x and y direction) of the pin grooves on the bottom of the model.
  • 250 9.ModelDieWithBoreProcessorControl.ModelBottomPinGrooveWidth.gif

  • 13 Determines the depth (i.e. z direction) of the pin grooves on the bottom of the model.
  • 250 10.ModelDieWithBoreProcessorControl.ModelBottomPinGrooveDepth.gif

  • 14 Check box for activating/fabricating hollow model. If the Hollow model check box is checked, the wall thickness [15] of the hollow model can be adjusted by using the slider for a precise value.
  • 250 11.ModelDieWithBoreProcessorControl.ModelWallThicknessCheckbox.gif

  • 15 Wall thickness of the model. If the wall thickness is 0, the model will be solid. You can also achieve that by unchecking the Hollow model.The positive number means the model will be hollow and will define the material thickness. Negative value is invalid. See image Wall thickness.
  • Plateless Model Settings 3.1 3.png

    250 12.ModelDieWithBoreProcessorControl.ModelWallThickness.gif

  • 16 Adds an extension in wall thickness towards the bottom of the model. This increases the surface area in contact with a printer build plate and adds strength to the model walls. A value of 0 removes the still feature. See image Bottom sill
  • 250 13.ModelDieWithBoreProcessorControl.ModelWallBottomSill.gif

  • 17 Determines the size of a ball that needs to fit into the cavity of a hollow model. Any region where such a ball would not fit is filled with material. Negative values are invalid.
  • 250 14.ModelDieWithBoreProcessorControl.ModelWallMorphologicalClosureDiameter.gif

  • 18 Activate the checkbox Anticipate milling.
  • 250 15.ModelDieWithBoreProcessorControl.ModelMillingHeadDiameterCheckbox.gif

  • 19 The diameter slider, determines the size of the bevel at the bottom of the separate dies, and the holes in the model base allow for milling residue in the opposite part. This will be displayed as Anticipate Milling.Use the slider [20] o change this value.
  • 250 16.ModelDieWithBoreProcessorControl.ModelMillingHeadDiameter.gif

  • 21 Model Analogs allows you to change the offset between the model and lab analog if it is configured in the Model Creator lab analog library. Use the slider to adjust the Horizontal offset [A] and the Vertical offset [B]. See this example.
