Cercon® ht ML

Aesthetics meets strength


14-unit bridge milled of Cercon ht ML, then glazed

High translucent multilayer zirconia

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.

Aesthetics meets Strength

Strength & Safety

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.

Lifelike gradient

The gradient of the layers matching natural tooth aesthetics in one disc without the need to veneer or stain.

Approved Color Accuracy*

Excellent color matching for all 16 VITA** shades and BL2.

Easy to use

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


Cercon ht ML layers

Lifelike gradient

Four integrated color layers after sintering lead to a dentine incisal gradient like a natural tooth. Without necessary veneering.

Advantages

  • Extra high translucency (41-49 %) and excellent shade accuracy allow for natural aesthetics, especially in the anterior region
  • All 16-VITA** shades and BL2 are available. Every shade has its own incisal shade.

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.

Nesting in a Cercon ht ML disc

Approved Color Accuracy*

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

 

 

Cercon ht ML: high translucent multilayer zirconium oxide

Easy to use

Easy to nest and same sintering programs for all Cercon zirconia discs. Just glaze and go.

Advantages

  • The layers in the incisal area are the same for all disc sizes, only the dentin area varies in thickness. This additionally leads to extra easy nesting for the dental technician.
  • Improves productivity with reproducible restoration results while also saving processing time (milling, sintering, glazing)
  • Same sintering programs for all Cercon zirconia discs
  • Speed sintering in less than 3 hours for all Cercon zirconia discs
  • QR code scanning for easy use in inLab MC X5 (from CAM Software version 20.0.1)
  • Positioning aid for safe repositioning of the blank
Nesting in a Cercon ht ML disc

Nesting in the disc:

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.

Covering discolored dies

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

Covering discolored dies with Cercon ht ML zirconium oxide

Finishing

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.

• Yttrium oxide 5 – 9%
• Hafnium oxide < 3%
• Aluminum oxide, Silicon oxide, other oxides < 2%
Flexural strength750-1200 MPa
Translucency2
41-49 %
CTE (coefficient of
thermal expansion)
10,5 μm/m·K
(25 – 500 °C)

Indications

 

 

 

 

 

Indications in the anterior and posterior segments

Cercon® ht ML is indicated in the anterior and posterior segments for:
• Crowns
• Telescopic primary crowns
• Multi-unit bridges (with no more than two pontics between abutment crowns; with no more than 6 units3)
• Two piece abutments4


Cercon® ht ML can be used as a substructure (framework) which is then veneered with a dental veneering ceramic or can be used for full-contour application (without veneering) as well.
In the case of telescopic primary crowns, the substructure is not veneered.

Sintering temperature1500 °C
