Using Copy Denture Scans as an Impression to Design a New Denture

It is possible to use Copy Denture scans to design a new denture. This workflow requires aligned scans created during the Copy Denture scanning workflow.

For information about creating and scanning Copy Denture orders, refer to the "Copy Dentures – Order Creation" and "Copy Dentures – Scanning" sections of the Technical Documentation.

Designing a New Denture from Copy Denture Scans

Step 1: Create a new order and select the required denture type.

Step 2: Set the "Object type" to "Digital Impression".

Step 3: Import the scans:

• Import the upper denture scan as the upper scan.
• Import the lower denture scan as the lower scan.
• Import the upper denture scan again as the wax rim scan.

Step 4: Go to the "Refine upper jaw scan" step and then the "Refine lower jaw scan" step.

Configure the settings as follows:

• Clear the "Improve scan borders" checkbox.
• Select the "Impression" checkbox.

  Step 5: Proceed to the "Occlusal alignment" step.

Use the upper jaw scan imported as the wax rim to define the occlusal plane by placing points on the molars and upper anterior teeth. Adjust the occlusal plane as required.

Step 6: Proceed to the "Trim the upper jaw" step and draw the trimming spline.

Step 7: Proceed to the "Trim the lower jaw" step and draw the trimming spline.

Step 8: Proceed to the "Sculpt upper jaw" and "Sculpt lower jaw" steps.

Apply sculpting operations if required to correct scan artifacts, poor triangulation, or similar scan imperfections.

Step 9: Click "Next" to continue to the "Model Analysis" step.

From this point, continue designing the denture using the standard workflow described in the "Full Dentures" section of the Technical Documentation.

The completed denture is shown below.
