Marking the matrix and patrix of attachments

This procedure does not belong to the simple nesting workflow.

  1. Position your objects horizontally and vertically in the top view.
  2. Rotate your objects about the Z-axis in the top view.
  3. Check if all cavities and drillings are correct.
  4. Specify the drilling range for objects with unrecognized drillings.
  5. Mark the cavities for objects with unrecognized cavities.
  6. Set bars for all objects.

This procedure belongs to step 11 of the complete nesting workflow.

  1. Delete any incorrect machined areas.
  2. Change the status of objects and delete non-required objects.
  3. Position your objects horizontally and vertically in the top view.
  4. Rotate your objects about the Z-axis in the top view.
  5. Adjust the height position of your objects and/or rotate them about the X/Y-axis (required for multilayered blanks).
  6. Check if all cavities and drillings are correct.
  7. Specify the drilling range for objects with unrecognized drillings.
  8. Mark the cavities for objects with unrecognized cavities.
  9. Create a sinter bar for objects that require a sinter bar.
  10. Set drops for objects that require drops.
  11. Mark the attachment for objects with an attachment.
  12. Activate anterior tooth editing for the desired object)
  13. Edit or delete labels milled on objects.
  14. Set bars for all objects.

The patrix and matrix of attachments must be marked manually for optimum editing. Optimum editing includes grinding repetitions and using activated optional tools.

  • Open the Nesting view for adjusting objects with the following icon in the main icon bar:

Preparing the marking of attachments

  1. Make sure that you have added both the object with the matrix and the object with the patrix to the blank.
  2. Prepare the objects:
    1. Check for incorrectly marked drilling ranges and cavities.
    2. Mark all drilling ranges.
    3. Mark all cavities.

  1. (Optional) Select the desired object in the blank display.

    • DentalCAM highlights the object in the object list with a colored border.

    Figure is an example

  2. Open the editing functions for the required object with the following icon in the left column: 

    • The icon bar for the editing functions is displayed.

     

  3. Open the editing function for marking attachments with the following icon: 

    4. Opening the editing function for marking attachments (icons marked orange)

    • In the left column, icons for marking the attachments display. In the blank display, DentalCAM hides all elements except for the selected object.

    2. Icon for selecting reference points
    3. Icon for correcting the calculated shape of the attachment
    4. Icon for completing the workflow

Marking the matrix

  1. Start the workflow by selecting the following icon in the left column: 

  2. Position the view so that you are looking into the matrix from the insertion direction of the patrix.

    • Choose a steep angle.

    • You must be able to see a good portion of the inner contour of the matrix.

    3. Example: Inner contour of the matrix is visible; insertion direction of the patrix is indicated by an arrow

  3. Continue by selecting the following icon in the left column: 

  4. Select 2 points on the part of the inner contour that runs parallel to the insertion direction of the patrix. Leave some space between the points.

    5. Example: The first point has been set, the second point still needs to be selected (possible location marked orange)

  5. The following happens:

    1. The blank display changes to top view.
    2. DentalCAM calculates the shape of the attachment and marks it accordingly:
      • Turquoise balls: The area is part of the attachment.
      • Black balls: The area is not part of the attachment.

    Example: Calculated contour of the attachment with errors (see orange markings)

  6. If necessary, correct the shape of the attachment.

    • Select a black sphere to extend the area to that sphere.

    • Select a turquoise ball to reduce the area to this ball.

    Your goal is to mark an area with the turquoise balls that is slightly bigger than the attachment.

    7. The marking of the contour has been corrected. It is a bit bigger than the contour itself.

  7. Finish the workflow by selecting the following icon in the left column: 

    • The following happens:
    1. DentalCAM re-calculates the shape of the attachment based on your input.
    2. When the calculation is finished, the attachment is marked in yellow.

  8. Save your changes with the lower arrow icon:

  9. Close the area for the editing function with the upper arrow icon:

Marking the patrix

  1. Start the workflow by selecting the following icon in the left column: 

  2. Move the view so that you can see a good portion of the contour of the patrix.

    3. Example: Contour of the matrix is visible

  3. Continue by selecting the following icon in the left column: 

  4. Select 2 points on the contour of the patrix.

    5. Example: The first point has been set, the second point still needs to be selected (possible location marked orange)

  5. The following happens:

    1. The blank display changes to top view.
    2. DentalCAM calculates the shape of the attachment and marks it accordingly:
      • Turquoise balls: The area is part of the attachment.
      • Black balls: The area is not part of the attachment.

    Example: Calculated contour of the attachment with errors (see orange markings)

  6. If necessary, correct the shape of the attachment.

    • Select a black sphere to extend the area to that sphere.

    • Select a turquoise ball to reduce the area to this ball.

    Make sure to also mark both radii at the sides of the attachment.

    7. The marking of the contour has been corrected. Both radii have been properly marked.

  7. Finish the workflow by selecting the following icon in the left column: 

    • The following happens:
    1. DentalCAM re-calculates the shape of the attachment based on your input.
    2. When the calculation is finished, the attachment is marked in yellow.

  9. Close the area for the editing function with the upper arrow icon:

Removing the marking of attachments

  1. (Optional) Select the desired object in the blank display.

    • DentalCAM highlights the object in the object list with a colored border.

    Figure is an example

  2. Open the editing functions for the required object with the following icon in the left column: 

    • The icon bar for the editing functions is displayed.

     

  3. Open the editing function for marking attachments with the following icon: 

  4. Select the following icon in the left column next to the label 1: 

  5. DentalCAM deletes the marking of the attachment.
