Dentsply Sirona Cercon base Gebrauchsanweisung Seite 12

Annealing:
Based on the results of our scientific testing of zirconia frameworks, we consider a separate annealing
("healing") step both unnecessary and inappropriate
Polishing in the laboratory:
Unveneered Cercon® base/Cercon® ht/Cercon® xt frameworks should be highly polished or glazed
with a high-gloss ceramic glaze This also makes the restoration more amenable to proper oral hygiene
procedures
Polishing in the dental office:
Extensive studies have shown that the abrasive action of Cercon® base/Cercon® ht/Cercon® xt on
antagonists is less than that of conventional ceramic veneers and not more than standard lithium
disilicate ceramics even after finishing and polishing
Important: After making minor final occlusal adjustments at chairside, we recommend prophylactic
polishing of the adjusted sites to a high luster or adding glaze with a smooth surface prior to tempo-
rary or definitive cementing to protect the antagonists from possible abrasion This also makes the
restoration more amenable to proper oral hygiene procedures
Tooth surfaces whose shade was obtained by staining may present brighter spots where occlusal
adjustments were made
Transport and storage:
No particular requirements
Shelf Life:
Shelf life of Cercon® base, Cercon® ht and Cercon® xt is 7 years from date of manufacture
