CEREC Biogeneric

CEREC Biogeneric is the first method which is able to reconstruct lifelike occlusal surfaces. On the basis of the features of a patient’s single intact tooth, the program extrapolates the naturally created morphology of other teeth. The biogeneric occlusal design functions for all single tooth restorations and fully anatomic bridges.

Currently, all occlusal design approaches are based on dental libraries and
databases containing data records of various standard teeth. Conventional
CAD/CAM programs retrieve a matching tooth from the archive, and then generate a design proposal for the given clinical situation. The user then manually edits and adapts this proposal. The biogeneric occlusal design is to replace the “dental database” design procedure applied in previous CEREC software versions. It will now be possible to create crowns, inlays, onlays, veneers, and anatomically sized bridges in a fully automated manner. The reconstruction can be based on any intact patient tooth from the same type, i.e. posterior tooth or anterior tooth. The often time-consuming process of manually adjusting the tooth to the clinical situation is now virtually a thing of the past. Moreover, due to the standardized and largely automated routines, the new software is easy to get to grips with and use.

Tools subgroup

Antagonist window
With the “Manual Trim” button in the “Antagonist” dialog box you can also hide image regions at a later point in time. For posterior tooth crowns with antagonist (design technique “Biogeneric” or “Biogeneric reference”), the “Settling”, “Cusp settling” and “Virtual grinding” buttons all have the same function as in the automatic crown suggestion (see “Options” in the “Settings” Chapter). You can use these functions if you have changed the suggested crown with the “Design” tools and would like to redefine the occlusal contacts.
For inlays/onlays in the design technique “Biogeneric” with antagonist, you can automatically set the occlusal contacts with these buttons. Automatic adaptations to the antagonist are performed for the inlay/only initial suggestion.

Settling button
With this button, the restoration is adapted to the antagonist so that the resulting contact situation is as stable as possible. The contacts should have as little penetration volume as possible. The morphology of the occlusal surface is not changed.

Cusp settling button

If the restoration features a cusp tip, the “Cusp settling” button is automatically enabled. This button triggers automatic adaptation of the individual cusps of the restoration to the antagonist. The cusps are adapted to the antagonist so that the resulting contact situation is as stable as possible. The morphology of the occlusal surface is changed.

Virtual grinding button
This button can be used to virtually grind the existing occlusal contacts. This function removes the red contacts down to a size that you have defined in the parameter dialog under “Occlusal contact strength”.
When designing inlays/onlays and crowns which are not automatically adapted, we recommend that you initially adapt the restoration to the present situation with the “Design” tools. Then you can finalize the contact situation with the following buttons in this order:

1. “Settling”
2. “Cusp settling”
3. “Virtual grinding”

Design window (3D viewer)

CEREC 3D contains a main window (3D viewer) for visualizing and
designing a restoration in 3D. The 3D viewer opens after all image fields have been acquired. The time up to display of the viewer depends upon the number of image fields and the number of single optical impressions.
You can do the following in the Design window:

  • view the image fields of the preparation, of the occlusion and of the antagonists as well as the restoration, either individually or in any combination,
  •  determine a new insertion axis,
  •  hide an image region by entering an open line mesially and distally,
  •  enter the preparation margin,
  •  immediately see the effects caused by applying a tool (e.g. editing, scaling …)
  •  view the restoration in the milling simulation before machining,
  •  rotate the objects arbitrarily.
  •  To do so, you press and hold down the left mouse button and move the mouse in the desired direction.
  •  The direction is indicated for better orientation (e.g. mesial, lingual …).
