SIRIUS NEWS 2/2011Translucent and colour reliable✔ ✔ Significantly improved light transmissionCercon ht offers a significantly improved light transmission towards other zirconiaframework brands.✔✔Safe staining formulaThe foundation formula using staining liquids offers reliable guidance in reproducingthe 11 most common Vita shades. The formula has been fine-tuned specifically forCercon ht; it is not transferable to other zirconia frameworks.✔✔Dipping and multi-colouring are availableYou have the choice between a single-shade dipped framework structure (dipping)or a multi-coloured undercoating.The multi-coloured shade system lets you create fully contoured restorations withreliable shades as per the shade guide. Multi-coloured Cercon ht frameworks forsubsequent veneering improve aesthetics and create additional depth. Cercon htand Cercon ceram love veneering ceramics will always result in a highly naturalappearance, even with thin veneer layers.The special shade formula makes the reflection behaviour of zirconia more harmonized,bringing it very close to nature.Cercon ht is characterized by anexcellent penetration depth. Minorocclusal adjustments can be madewithout compromising restorationshade (no bright spots).The multi-colouring technique is a three-step technique.Results of the multi-colouring technique.

SIRIUS NEWS 2/2011Allow the frameworks to dry sufficiently and place in the Cerconheat Plus as per the manufacturer’s instructions.The Cercon ht/DeguDent sintering parameters apply..SuggestionWeigh the framework on a gold scalebefore applying the liquid. The weight gainafter drying must not exceed 10%.!! Pre-dry all frameworks under infra-red light for 45 to60 minutes.!! Excessive temperatures may result in mottled shadesor even damage the framework.9

Cercon htcustomizedFinishing the shadeAfter the shade-sintering step, you can apply stain directly onto the framework.Perform any minor corrections to the framework using a water-cooledturbine. Following the multi-colouring Cercon ht staining, finish the shadingusing the Cercon body stains according to the combination chart related tothe Vita shade.Important notes!! Follow the manufacturer’s recommendations when applying the Cercon bodystains.!! Make sure the stains have a creamy consistency to prevent “islands” fromforming on the surface.!! Finishing the shade requires two firings (for shade assignments see page 11).!! The glaze firing is performed using Cercon glaze. Glaze firing is a necessarystep: the glaze is required to “seal” the surface.12

Insufficient drying times may cause frameworkdamage.!! Before sintering, thoroughly remove any dustor contamination (black spots).!! Unsuitable instruments or excessive pressuremay destroy the unsintered framework.!! Dry on a suitable surface in order to preventthe stain from running. Tissue is not suitable.!!
