By Sirona Dental Staff n Sirona Dental has announced the introduction of CEREC Zirconia, an all-ceramic substitute for the tradi- tional PFM (porcelain fused to metal), and the CEREC SpeedFire furnace into the family of Sirona products and technology. CEREC now provides a completely new process in the dental practice. Combining the new CEREC SpeedFire furnaceandCERECZirconiamaterial, dentists can now deliver full contour crowns and small bridges made of the full-strength, high-quality zirconium oxide in a single visit. Previously, the complicated work- ing steps required to process zir- conia limited its application to the laboratory environment. Sirona’s new CEREC Zirconia and SpeedFire furnace will bring many workflow steps together into a reliable, simple process, according to the company, making chairside production of zir- conia possible. CEREC Zirconia is a pre-shaded translucent zirconium oxide avail- able in 10 classic VITA shades. The materialismilledinanenlargedform and then densely sintered to its final size in the new sintering furnace, CEREC SpeedFire. The over-sized milling facilitates a new level of milling precision, lead- ing to superb fitting restorations, according to the company. The sinter- ing process takes 10 to 15 minutes for crowns and less than 30 minutes for bridges. The subsequent glaze firing gives a high-gloss finish to the restoration. Other benefits include minimal tooth reduction, financial savings as zirconia is less expensive than alternative materials and less post- operative sensitivity. The short process to produce CEREC Zirconia restorations is both convenient and economical, accord- ing to the company. With this intro- duction, Sirona also offers a new wet/dry mill option for its milling units. Dry milling reduces the overall processingtimeforzirconiaand,com- bined with the fast sintering cycles, enables the chairside procedure. The workflow is easy to learn, accordingtothecompany.TheCEREC Software 4.4.1 guides the dentist through the whole process, including sending the sintering and glazing information to the furnace. No pro- gramming of the furnace is required as the software handles it all auto- matically. Patients avoid messy impression material, receive less anesthetic and do not have to deal with a temporary crown.Now,withCERECZirconiaand the CEREC SpeedFire furnace, den- tists who prefer zirconia can provide crowns and bridges to their patients in a single visit.
