Virtual Planning Export & Model Builder

Virtual planning export and model builder

General workflow

Possible application scenarios

Proprietary export formats are mostly used in a dedicated workflow.

The examples below illustrate selected application scenarios for STL export, which is the most versatile export format. Other scenarios may be possible as well.

1. Export of surface scan with scanbodies

This is used to transfer data to a CAD/CAM system (=virtual IO scan with scanbodies).

Work steps include:

Select STL file export
Select the Untouched export option.
Tick the scan which is to be exported.
Tick the tooth positions to be included and assign scanbodies.
Select the export coordinate system. Use the coordinate system of the scan as export coordinate system, if the surface scan originally comes from a CAD system.
Click Export planning to export data.

2. Creation of model with holes for implant analogs

This is used to fabricate dental restorations with an analog workflow.

Work steps include:

Select STL file export.
Select the Insert implant analogs option.
Select the scan to be used to create the model.
Tick the tooth positions to be included.
Define implant analogs : Define an analog for each implant and have it subtracted from the model during calculation. Design the virtual analog in a way that it protrudes from the surface of the model to actually create holes in the model. Such holes must be designed to correctly hold the physical implant analogs which are used to build the dental restoration.
Adjust the block-out direction to get an even, well balanced model.
Set the block-out method. Block out open regions if you work with an open scan. If the result is not satisfying, have the model blocked out along its outline.
Select the export coordinate system. Use the coordinate system of the scan as export coordinate system if the surface scan originally comes from a CAD system. If you want to use the resulting STL file together with other objects (e.g. drill guide), choose the patient coordinate system for export

3. Creation of model from an IO or impression scan

This workflow is used to fabricate a plain model (without implant information).

Work steps include :

Select STL file export.
Select the Insert implant analogs option
Select the scan to be used to create the model.
Do not include any tooth positions (remove the checkmarks).
Adjust the block-out direction to get an even, well balanced model.
Set the block-out method. Block out open regions if you work with an open scan. Set the socket height to 0 mm
Select the export coordinate system. Use the coordinate system of the scan as export coordinate system if the surface scan originally comes from a CAD system. If you want to use the resulting STL file together with other objects (e.g. drill guide), choose the patient coordinate system for export.
Click Export planning to export data.

4. Creation of model to fabricate a deep-drawn guide

This is used to fabricate a deep-drawn drill guide with an analog workflow.

Work steps include:

Select STL file export.
Select the Insert implant analogs option.
Select the scan to be used to create the model.
Tick the tooth positions to be included.
Define implant analogs.
Define implant analogs. Define an analog for each implant and have them integrated with (added to) the model during calculation. Analogs will form posts in the resulting model and hold the sleeves. Such posts should have a plateau on their top to ensure the sleeves are well seated, and must hold the sleeve in the correct height.
Adjust the block-out direction for the model. The block-out direction coincides with the insertion direction of the guide
Set the block-out method. Remove all undercuts when blocking out the model
Select the export coordinate system. Use the coordinate system of the scan as export coordinate system if the surface scan originally comes from a CAD system. If you want to use the resulting STL file together with other objects, choose the patient coordinate system for export.

5. Export of a segmentation for import in a CAD-CAM system

This is used to subsequently process such segmentation with a CAD-CAM system.

Work steps include:

If possible, import and match a scan of your patient situation with your DICOM data. The scan should come from the same CAD system in which the segmentation is to be imported subsequently.
Select STL file export.
Select Untouched export.
Tick the segmentation of your dataset (instead of a scan). Adjust the level of detail if required.
Do not include implants.
Choose the coordinate system of the scan which you have imported before as export coordinate system. This way, the segmentation will appear aligned to the scan in the CAD system.
Click Export planning to export data.

6. Print a segmentation for presentation purposes

This is used to print a segmentation for presentation purposes.

Work steps include:

Select STL file export.
Select the Insert implant analogs option.
Select the segmentation of your dataset which should be printed. Adjust the level of detail if required.
Tick the tooth positions to be included.
Define implant analogs. Define analogs for the implants and have them subtracted from the model during calculation. Design the analogs in a way that they protrude from the surface of the model to actually create holes in the model. If implants shall be placed in the printed segmentation, the size of the analogs designed in coDiagnostiX must meet the implant dimensions.

If the segmentation is very complex, coDiagnostiX might not be able to deduct the holes. In such a case, use Multi-file export and process your data with a separate software.

7. Export of data for bone block design

This export is used to provide bone and implant planning information to bone block manufacturers for customized bone block design and manufacturing. An alternative way to provide such data is sending them to the service provider through caseXchange (see Requesting services in the caseXchange chapter).

Prior to export:

Segment the affected jaw bone (check with the bone block provider if partial or full jaw is needed).
Plan the implants with the usual procedure.

Export work steps:

Select STL File to Export
Select the Insert implant analogs option.
Select the bone segmentation that is relevant for design. Adjust the level of detail if required.
Tick the implants to be included in your export.
Define an implant analog for each implant. Use the standard cylinder with the implant's diameter and length. Integrate the implant analog with (=add to) the model during calculation.
Set the export coordinate system to Patient coordinate system.
Enable Multi-file export (check with service provider if required).
Click Export planning to export data.
