Why choose Cercon xt ML?

Lifelike Gradient

Matching natural tooth aesthetics without the need to veneer or stain, especially for the anterior region (flexural strength: 750 MPa)

Easy to use

Easy to nest and same milling and firing protocols for all Cercon zirconia discs

Approved Color Accuracy¹

Excellent color matching for all 16 VITA®2 shades and BL2. Consistent quality from batch to batch. Color accuracy confirmed by dental technicians from Europe and the USA.

Zirconia Multilayer Material

The layering in the incisal area is the same for all disc sizes; only the dentin area has a different thickness. This makes nesting particularly easy for the dental technician.


The finishing of all-ceramic restorations is an essential component of aesthetics and quality. Cercon Multilayers can be finished with only a single glaze or by an individual characterization with stains.

Examples: bridges and crown, milled in Cercon xt ML, Shade A2, finished with Dentsply Sirona Universal Stain & Glaze.

Zirconia in the digital workflow

Dentsply Sirona offers the full range of products required to process zirconium oxide in the digital workflow. From scan and design via mill, sinter and finishing to the cementation.
