Abstract:

Objective Cercon all-ceramic system was applied clinically for the first time to make all-ceramic crowns and bridg- es for the patients. The objective of this study~to evaluate the short-term follow-up results of this new system from both techni- cal and clinical aspects. Methods巧units of Cercon all-ceramic crowns and bridges were fabricated and applied to 5 patients, all the cases were followed at 1，3, 6 and 12 months' periods after cementation of the restorations. Results Cercon all-ceramic system demonstrate natural and esthetical appearance. No fracture, broken and color change were found. Conclusion The reli- ability of all-ceramic~and bridges made from Cercon system was greatly improved due to the strengthening effects of the zir- conia copings and substructures, and the indication of this system can be extended to long span posterior bridges. In addition, the better esthetics compared to PFM technique makes it a comparatively ideal all-ceramic system for crowns and bridges.
