Free Mode

自由模式

The Free Project mode is a specific use of OpticalRevEng Dental, suggested when the user needs to acquire some data that does not fit in any of the supported Structed Projects.
The free mode can be used to experiment the scan system or to scan a single object.
In free mode there is no Project Tree, no automatic alignment and no Step-By-Step Wizard. However, it is still possible to acquire data, align two objects together, generate a mesh and edit all the information.

The project logic is completely in the user's hands, who is responsible to correctly choose a reference item, align all the objects and choose the best scan and mesh strategy for all the project data.

Some tools work differently in Free Mode, as the project can lack some information.

Acquisition

In Free Mode, the software has no information regarding the type of object to be scanned, its name or its color.
By clicking the Acquisition button, an extra dialog will ask to add this information.

Alignment

In Free Mode, the software can't automatically identify the reference item. To align two objects, use the drag and drop function as explained in the Project Tree page.

Mesh Generation

As no information was provided about the scanned object, an extra dialog will require the user to define the appropriate Mesh Generation strategy.
In the same dialog, it is also possible to choose whether to aggregate the acquisition or not.

If aggregate is checked, the software will create just one mesh with all the selected acquisitions.
If aggregate is not checked, each acquisition will be separately converted.

Implant Alignment

When an implant marker is aligned to its implant library, the tooth position of the Scan Body needs to be manually defined.
Select the correct implant position or the identification will not be correctly exported

Exocad Export

In a free project, the software can't automatically export the data to Exocad.
By clicking on the Export To CAD button, a wizard will start. The first page will ask:

• In which folder the data has to be exported
• If the user wants to export a single model (with or without a bite) or two stone models

Then, after clicking next, the software will ask the user to specify the status of each mesh in the project.
For every jaw, the following meshes can be identified:

• Master Meshes : all the meshes that are part of the stone model: healthy parts, stumps, pontic parts, etc.
• Gingiva Meshes : mesh of the separated gingiva
• Markers : meshes of the implant markers
• Pre-Op or Waxup : mesh of the Provisional Model or of a Waxup, selecting the type of element.

When all the meshes are identified, click Export to save the files on disk.
