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. It is recommended to nest the crown or bridge in the upper part of the disc to achieve the optimum aesthetic result. The graphic depicts layers of an 18mm Cercon ht ML disc.
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.
Composition (in % by mass)
Flexural strength: 750-1200 MPa
Translucency2: 41-49 %
CTE (coefficient of thermal expansion): 10,5 μm/m·K (25 – 500 °C)
Indications in the anterior and posterior segments: Cercon ht ML is indicated in the anterior and posterior segments for:
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.
