As the pioneer for already precolored and presintered zirconia and together with dental technicians from the USA and Europe, we have developed different layers in our multilayer zirconia to create the most suitable material and color gradient.
Cercon ht ML is the hybrid zirconia multilayer for the combination of high strength and natural aesthetics. From a single crown to a 14-unit bridge. None nesting restrictions even for widespan bridges.
From single crowns up to 14-unit bridges, based on the high bending strength (gradient from 1200 MPa in the dentin up to 750 MPa in the incisal) and over 20 years of documented Cercon experience.
The gradient of the layers matching natural tooth aesthetics in one disc without the need to veneer or stain.
Excellent color matching for all 16 VITA** shades and BL2.
Easy to nest and same milling and firing programs for all Cercon zirconia discs.
Four integrated color layers after sintering lead to a dentine incisal gradient like a natural tooth. Without necessary veneering.
Advantages
Being a hybrid zirconia multilayer material, Cercon ht ML combines high flexural strength and natural tooth aesthetics in one disc with a gradient from 1200 MPa in the dentin up to 750 MPa in the incisal.
Graphic depicts layers of an 18mm Cercon ht ML disc.
Excellent color matching covering all 16 VITA** shades and BL2
Decades of expertise in ceramic coloring
Consistent quality from batch to batch (an A3 is always an A3)
Color accuracy confirmed by dental technicians from Europe and the USA
Easy to nest and same sintering programs for all Cercon zirconia discs. Just glaze and go.
Advantages
It is recommended to nest the crown or bridge in the upper part of the disc to achieve the optimum aesthetic result.
Example:
Placement of the restoration in CAM software in an 18-mm Cercon ht ML disc.
Especially in the anterior region, depending on the degree of discoloration and wall thickness of the restoration. Example: Cercon ht ML, Shade A2, 1.5mm wall thickness
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: 14 unit bridge, milled in Cercon ht ML, Shade A2, finished with Dentsply Sirona Universal Stain & Glaze.
