CAD/CAM technology for zirconia based ceramics frameworks achieving

Restorations produced with computer assistance are increasingly being adopted in dental technology. The aim of the study was to evaluate the effectiveness of the technological procedures in achieving zirconia based ceramics frameworks using Cercon CAD/CAM system. Data capture from models were made using an 3D laser scanner The virtual 3D dental restorations were designed on the computer screen following the specific steps. The CAD software transforms the virtual model into specific set of commands which drive the CAM unit. CAM complete restorations were created by substraction from presintered soft prefabricated zirconium oxide blocks, and finally these were sintered. Using Cercon system a wide variety of frameworks from zirconia based ceramics can be fabricated. After initiation, handling with Cercon CAD/CAM system is easy for the practitioner.
