Successful use of all-ceramics in posterior crown and bridge depends on
The right material for the restoration based on position in the mouth and expected stress levels on the material.
MINIMAL restoration thickness of 1.5 mm in all excursive movements.
Smooth shoulder finish line preparations.
Clear and distinct CEREC images or impressions.
Opposing occlusion that is uniform and allows centralized contacts on your restorations
Connector dimensions for bridges of minimally 9 mm2.
Selecting the proper base ceramic shade…choose the lightest shade seen on adjacent teeth, determine whether the adjacent teeth appear opaque/chalky or violet/translucent, and include a shade tab of the most chromatic area of the tooth. The most chromatic area is usually the cervical or body of a natural tooth. A clinical photo with a shade tab included in the image is a huge help.
Clinical Protocol for Bridgework
Send impressions, cast, and mounted casts, or CEREC digital data through CEREC Connect after identifying the finish lines of the proposed restoration.
We will design the virtual restoration (and send you several screen shots if you would like to see the proposal).
We will fabricate the zirconium framework and send it to your office in a few days for a framework try-in with your patient.
You let us know the moment this framework fit is verified. We will immediately begin fabrication of the e.maxCAD superstructure.
Return the framework to us for completion of the project. Let us know any further shading or characterization instructions for the e.maxCAD superstructure.
We will have it back for seating. If any further changes in shade, character, or contacts are required, no problem, send us your ideas with the bridge.
