Crowns & CAD-ON Bridges


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.
