Adapting to occlusion and adjacent (proximal)

Free Forming - ADAPT -Occlusal - PIC(3).png

This screen allows you to adapt restorations to the antagonist (if scanned), and to the adjacent teeth.

If you have used the Virtual Articulator feature (available as an add-on module; requires supported scanner for a direct facebow transfer or you can manually set the occlusal set using Bonwill's triangle), you may chose between static or dynamic occlusion [17].

You can define a desired distance to the antagonist (for anatomic and reduced parts) using the slider(s) desired distance [16].

For the actual adaptation, you have the choice between a smart shape-preserving adaptation [15], which will try to preserve the tooth morphology, or simply cutting intersections with the antagonist, cut intersection [14].

To adapt to anterior teeth, switch to Approximal [13].

TipUse a combination of both – first the shape-preserving adaptation [15], which will keep small intersections, then cut intersections [14].

When Pull to Adjacent Teeth[18] is checked, the teeth will be adapted even if there is no contact prior to adaptation

When done, click 'Next'.

Adapting pontics to the gingiva

Free Forming - PONTIC - PIC(2).png

Using the "Pontic" tab, you can adapt pontics to the gingiva. The Desired Distance [21] 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.

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 [21] is respected in the final restoration, perform the adaptation after the reduction.

TipCheck Pull down to gingiva [22] 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)
TipYou control the ridge-lap position of the pontic during the placement of the pontic shape

Finally, click Adapt to gingiva [20] to perform the actual adaptation.
