BENSHEIM, Germany -- Sirona Now Offers its Customers CAD/CAM Systems and Materials From a Single Provider; New Ceramic Blocks will Complement the Selection Currently on Offer by the Company's Materials Partners

Sirona Dental Systems, Inc. (Nasdaq: SIRO), one of the world's leading manufacturers of high-technology dental equipment, today announced it has developed its own range of millable ceramic blocks for the Sirona CAD/CAM systems CEREC and inLab. The feldspath ceramics for chairside restorations (CEREC) will be available to customers as CEREC blocks. The Company's inCoris product line for dental labs will be expanded to include aluminum and zirconium oxide blocks. The new ceramics assortment, expected to be offered over the course of the year, will complement the current selection on offer from the Company's partners including VITA, Ivoclar Vivadent and 3M ESPE for the CEREC and inLab CAD/CAM systems. Sales will be managed by Sirona dealers.

Sirona developed the new ceramic blocks together with well-known material manufacturers including the Company's long-term partner VITA. "As the market leader for dental CAD/CAM systems, we are responding to the demand of many customers who wish to obtain all of their components from a single source. Of course, we will continue our intensive and successful cooperation with our materials partners in the future to further increase acceptance of restorations produced using CAD/CAM systems", commented Jost Fischer, Chairman, President and Chief Executive Officer of Sirona Dental Systems, Inc.

Since April 2006, Sirona has been offering non-precious metal alloys for dental labs under the brand name inCoris NP (Non-Precious). A special laser procedure is used to create frameworks from this alloy, which dental labs can order via the infiniDent Internet portal for further processing.
