Dentsply Sirona Cercon xt ML Instrucciones De Uso página 11

Manual finishing after sintering:
• Sandblast the inside and outside of the framework with aluminium oxide
(110–125 μm, max 2–3 bar, 45 ° angle)
• Eliminate premature contacts one by one until the framework has reached its final position on the die(s)
• During the try-on and fitting of the framework, keep the dies on the cast and try on the framework
as a whole
• Once the try-on and fitting has been completed, do not perform any additional adjustments such as
finishing the entire framework
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 individualization of fully contoured Cercon® xt ML restorations we recommend
Dentsply Sirona Universal Stain & Glaze
Layering technique
We recommend Cercon® ceram Kiss / 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
Surface treatment in the dental lab:
Unveneered Cercon® xt ML 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® xt ML 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® xt ML is 7 years from date of manufacture
