About the workshop:

The increasing demands for an esthetic high strength material coupled with the inherent drawbacks of other materials available in the market, has stimulated the development of the superior Celtra Duo Block which combines both high esthetics and highest strength values. The workshop will focus on the superior properties of Celtra duo, being a dual use block that can be finished and polished or glazed for various clinical situations.
Celtra Duo preparation guidelines and the Cerec design parameters will be highlighted with the most recent Cerec SW 4.5 with the shade detection option.
