Dentsply Sirona Cercon base Instrucciones De Uso página 12

Note: Sintered zirconia should be finished using diamond instruments under proper irrigation only
Keep the pressure on the framework material to a minimum and work only in one direction
• Sandblast the finished areas once again with aluminium oxide (110 – 125 μm, max 2 – 3 bar, 45 ° angle)
• Finally, clean the framework using a steam cleaner
Staining technique
For tooth-coloured staining of fully contoured Cercon® base, Cercon® ht and Cercon® xt restorations we
recommend Dentsply Sirona Universal Stain & Glaze
Layering technique
We recommend Cercon® ceram Kiss / Cercon® ceram love / Celtra® Ceram ceramic veneering materials for
veneering zirconia frameworks Make sure to follow the applicable Instructions for Use
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 and 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 and 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 lustre or adding glaze with a smooth surface prior to temporary 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
