Duplicate denture

This page documents exocad's software releases from 2025 on. See documentation for older versions

With the duplicate denture option, reproduce the patient's existing denture, considering the new anatomical situation, in a highly automated workflow. After the tooth segmentation, the teeth can also be adjusted to change the existing design. Instead of relining an old denture, rapidly and inexpensively produce a new one.

In DentalDB, select the specifications as usual for the Full Denture. You will need an additional Scan, the 360° denture scan. In the Copy existing scanned denture? section, select Yes. Click OK to continue.

Select Design to start the DentalCAD.

The first step is the Scan Data Editor, which allows you to edit the mesh. You can also open the Free-form Denture Scans in this step.

Use Free-form Denture Scan step to make the necessary changes. Check this page for further information using this tool.

In the next step, the margin of the denture is automatically detected. You can make the necessary adjustments using the Draw free [1] option or Edit [2]. Use the Start auto detection [3] button if it’s not detected automatically. Use the Set from view [4] option to adjust the insertion direction. Click Accept drawing changes [5] to generate the jaw scan.

Clicking next you will enter the Denture tooth Segmentation step. If the Cloud services are enabled, the segmentation starts automatically.

Click any tooth to extract it, using the Define tooth centers by click [6]. You can also Start the auto-segmentation [7] using the available Cloud services. In the Correction [8] tab, you can make any necessary corrections by drawing. The teeth become colorful after the segmentation is completed.

If required you can correct the denture tooth placement in the next step.

Afterwards, you can also use the Free-forming tools.

In the next step you need to design the bottom side of the denture base as you would do for a regular full denture. Click here to find more information about this topic.

After the bottom side of the denture base is created, the denture base is generated automatically. You can now create the connectors.

Then, you can Free-form the denture base. Click 'Next' to proceed.

Once that's finished, you can Adapt Denture Base to Teeth. The software will trim the teeth basally to maintain the minimum thickness of the denture base.

At last, in the Merge and Save restorations step the design is finished and the files are saved to the project directory.
