The „Freeforming“ screen gives you access to the following features:
- Anatomic forming: Changing the shape of the tooth anatomy, while taking advantage of the intelligent library models
- Virtual wax knife - adding or removing material, smoothing
- Adaptation of pontics to the gingiva
Click & drag on the tooth to change its shape.
|Use buttons - to change the area that you're editing:
- „Cusps“  edits individual cusps. Note that this only works properly for restorations based on model teeth (anatomic crowns/copings, anatomic inlays, etc), for offset copings or waxups, the software cannot know the location of the cusp.
- „Tooth parts“  edits the mesial, distal, buccal, lingual side , whereever you click on. Useful e.g. for adjusting approximal contacts.
- „Entire tooth“  edits the entire tooth.
|Useful hotkeys are available in the „Entire tooth“ mode. Hold <CTRL> to switch to rotation, <SHIFT> to switch to scaling. This way, you can rotate or scale the tooth, while it still stays attached to the preparation margin. As always, the software will remind you of the available hotkeys if you move the mouse over the respective button .|
- „Ridge“  is for fine-tuning of ridges/bulges.
|You can also drag and drop the bottom of a pontic when in „Anatomic“ forming mode.|
By unfolding the „Advanced options“ expander, you can get access to options that allow you to restrict the movement in certain ways. Using , you can restrict movement to occlusal direction (up/down) only. Using , you can hold certain parts of the tooth fixed: either the cusp tips or the equator.
|A useful example how you can take advantage of this option: To create deeper or flatter fissures, switch to „Entire tooth“ , then check „Cusp tips“ . Now, you can simply drag and drop fissures to make them more or less pronounced, without overly changing the rest of the tooth shape.|
The „Free“ tab – adding or removing material, smoothing
Click on the „Free“ tab to switch to the „Virtual Wax knife“, which allows you to add or remove material. You can toggle between adding/removing material and smoothing/flattening using buttons  and .
Adding / removing material:
To add material, click on the tooth and hold the mouse button. The longer you hold it, the more material will be added.
|Hold <SHIFT> to remove material|
Activate Smooth mode , click and hold the mouse button on the parts you'd like to smooth.
|Hold <SHIFT> to flatten (super-smoothing)|
Hold <CTRL> for a more shape preserving smoothing
|You can also use the smoothing option to remove certain artefacts (e.g. due to bad scan data when doing digital copy milling).|
Adjusting the brush
Using slider , you can adjust the speed at which material is added or removed while you hold the mouse button (or the amount of smoothing when in „Smooth/Flatten“ mode). Slider  controls the brush size, that is, the area that is affected around the mouse pointer.
|You can switch to a different virtual tool using . For example, the „Point of knife“ tool is useful for carving fissures.|
Adapting pontics to the gingiva
|Using the „pontics“ tab, you can adapt pontics to the gingiva.
The „Distance“ slider  controls the distance to the gingiva after the adaptation:
- A negative value means that the pontic will intersect the gingiva scan (that is, the physical pontic will apply pressure on the gingiva)
- A positive value means that there will be a gap between gingiva and pontic
- A zero value (default) means that the pontic will be in direct contact with the gingiva
|Check the „Pull down to gingiva“ box  if the gingiva is so low that the pontic doesn't intersect it to begin with. This will pull down the pontic towards the gingiva during the adaptation (Alternatively, you can pull the pontics down to the gingiva manually by dragging on the bottom while the „Anatomic“ tab is active). |
When designing reduced pontics, the „Freeform“ screen will appear twice, once before and once after the reduction. Therefore it's your choice whether to perform the pontic adaptation on the full anatomic or on the reduced shape. To make sure that the exact distance value  is respected in the final restoration, perform the adaptation after the reduction.
Finally, click „Adapt to gingiva“  to perform the actual adaptation.
Adaptation to antagonists / approximal adaptation
This screen allows you to adapt restorations to the antagonist (if scanned), and to the ajacent teeth.
If you have used the Virtual Articulator feature, you may choose between static or dynamic occlusion .
You can define a desired distance to the antagonist (for anatomic and reduced parts) using the slider(s) .
For the actual adaptation, you have the choice between a smart shape-preserving adaptation , which will try to preserve the tooth morphology, or simply cutting intersections with the antagonist .
To adapt to anterior teeth, switch to the „Approximal“ tab .
|Use a combination of both – first the shape-preserving adaptation , which will keep small intersections, then cut intersections .|
