The Impression-free Cerec Multilayer Bridge with the CAD-on Method

Two new developments extend the spectrum of the Cerec applications: Cerec-Connect: The entire mandible and maxilla can be scanned, as well as their relationship to one another, with the intraoral scanner. Multilayer technique for up to four-unit fixed dental prostheses (FDPs): the CAD-on technique from Ivoclar is the latest procedure in which a zirconium oxide framework and a veneer structure of e.max-CAD are bonded together by ceramic. Intraoral data acquisition with Cerec-Connect, design with Cerec-inLab and fabrication of the three-unit FDP are described and illustrated with a clinical case, and further developments are suggested.
