Dr. Dalin: This month I am talking with Michael Augins, president of Sirona Dental Systems, LLC. The company has recently released CEREC AC, along with some other enhancements to the CEREC system. Michael, would you give me a brief history of the CEREC unit?
Augins: The CEREC method was developed by Drs. Moermann and Brandstini at the University of Zurich. The first patient was treated in 1985 with a prototype unit 5, and in 1986, Siemens acquired the license to market and develop the system. In 1994, the CEREC 2 unit was introduced. In 1997, Patterson Dental became the exclusive North American distributor of the system and the dental division of Siemens was spun out. This resulted in the formation of Sirona.
In 2000 and 2003, new software changes were introduced that made the system easier to use. In 2007, the MCXL milling chamber was introduced and in 2009 the CEREC AC, powered by Bluecam, debuted.
Dr. Dalin: How has the Bluecam improved the system?
Augins: The Bluecam has improved the speed, accuracy, and ease of use for capturing digital impressions. This allows users to take full arch digital impressions that can be sent to a milling machine or lab via our connect capabilities.
Dr. Dalin: So the biggest selling points of these units are high precision, ease of use, and speed. Let's look at this from the perspective of an average general practitioner. Why should he or she take a serious look at adding this technology to a practice? We know the accuracy is good, but what about the ROI (return on investment)?
Augins: There are economic benefits to the doctors and to their patients. When a dentist creates restorations chairside, he or she keeps the entire professional fee because costs of impression materials are eliminated, as well as the fees of the second appointment. Generally speaking, the break–even point can be achieved with 10 to 14 chairside units manufactured per month.
For larger restorations, three– or four–unit bridges for example, the dentist can benefit by eliminating the cost of impression materials and transmitting digital impressions to the lab.
Dr. Dalin: I understand another concern is doctor and staff training. In order to make this technology work, how much training is required?
