It is possible to fabricate a try-in as a single piece from tooth-coloured wax prior to milling the bases in resin. This then serves to correct the digital set-up.


Generation in CAD

9 Monoblock zusammenfügen.png

The function for creating monoblock prostheses can be selected in the context menu after modification of the denture bases and teeth. After changing to the expert mode, this menu can be opened in the background with a right click.

19 Merge to Monoblock.jpg


To create the monoblock prosthesis, one selects the function „Full denture merge to monoblock“ [5]. Then the maxilla and mandible are each saved as single pieces including the teeth, and can be milled subsequently.


TipThe generated monoblock data sets are not exported, but are saved exclusively with the scenario..



Processing of monoblock dentures in the Ceramill System after patient try-in

14 neu.png

After the try-in of monoblock dentures in the patient's mouth, a number of situations may arise where possible necessary changes need to be included in the final resin denture within the Ceramill Mind software. These can be applied by markings on the monoblock denture. The procedures for the following situations are explained subsequently:





__Situation 1 – No changes necessary following try-in

__Situation 2 – Change of gingival shape necessary

__Situation 3 – Change of tooth positions necessary

__Situation 4 – Change of tooth sets necessary

__Situation 5 – Correction of bite necessary


Starting further processing is performed via the desktop link "Ceramill Mind“ as a matter of principle.

Situation 5 – Correction of bite necessary

If the bite has changed, the previously calculated static set-up areas have become void and need to be updated.

__To this purpose, the models need to be re-articulated.

__The case must therefore be generated new and scanned with the changed bite/articulation in order to determine the thus changed static set-up areas new.

__The previous tried-in monoblock denture can act as set-up aid in the form of a situation model.
