Introduction

Cercon ht

The new zirconia generation

A wish comes true Expectations of a contemporary prosthetic material include multiple colouring and natural translucency.

Cercon ht, with its outstanding translucency, combines 10 years of Cercon experience with current expectations of a state-of-the-art aesthetic shade result. For both the fully contoured variety and for the combination with Cercon ceram love or Cercon ceram Kiss a wish comes true for achieving individually tailored restorations with Cercon.

Sincerely, Team Sirius

✔ ✔ Safe staining formula The foundation formula using staining liquids offers reliable guidance in reproducing the 11 most common Vita shades. The formula has been fine-tuned specifically for Cercon ht; it is not transferable to other zirconia frameworks.

✔ ✔ Dipping and multi-colouring are available You have the choice between a single-shade dipped framework structure (dipping) or a multi-coloured undercoating.

Details for pre-sintering

Fully contoured objects within the blank.

The objects are finished using clean cross-cut tungsten carbide cutters.

Translu Finishing frameworks with fully contoured aspects is a very delicate task.

Carefully select your tools to avoid damaging the framework. Carefully finish and smooth the areas where connectors were attached in the blank.

Minor imprecisions in contour may also be corrected. Always work at low speeds, avoiding pressure.

Keep all cutters absolutely clean to protect the material’s favourable physical properties. ! ! Make sure that the surface has some residual roughness (chalky surface) to allow penetration of the stain according to the formular. ! ! While finishing, do not apply excessive pressure. The framework is very delicate and easily damaged. ! ! Use only Sirius Ceramics rubber cups. Other rubber cups may leave inclusions in the surface (black spots).

Tools

Reliable shade sintering Use utmost care when working with colouring liquids. Avoid any contact with the skin. Follow the manufacturer’s safety recommendations.

Important notes ! ! The brush must not contain any metal. ! ! The holding clasp must be protected by plastic tubing to prevent the metal from having contact with the liquid. ! ! Use the brush with smooth, uninterrupted movements. ! ! Rinse the brush in neutral liquid before changing shades. ! ! Return residual liquid to its container.

Allow the frameworks to dry sufficiently and place in the Cercon heat Plus as per the manufacturer’s instructions.

The Cercon ht/DeguDent sintering parameters apply. .

Suggestion Weigh the framework on a gold scale before applying the liquid. The weight gain after drying must not exceed 10%. !! Pre-dry all frameworks under infra-red light for 45 to 60 minutes. !! Excessive temperatures may result in mottled shades or even damage the framework.

Important notes !! The procedure requires five steps. Brush out the liquid for each of the regions described with the associated shade using smooth, uninterrupted movements. !! The liquids, and two intensities: colour (more intensive) and Prettau (weaker). ! ! Once the stain has been completely applied, place the framework on a level surface and dry under an infra-red light for at least 30 to 45 minutes. ! ! Do not place on a metal surface or on tissue, as these may react with the staining liquids!

Finishing the shade After the shade-sintering step, you can apply stain directly onto the framework. Perform any minor corrections to the framework using a water-cooled turbine. Following the multi-colouring Cercon ht staining, finish the shading using the Cercon body stains according to the combination chart related to the Vita shade.

Important notes !! Follow the manufacturer’s recommendations when applying the Cercon body stains. !! Make sure the stains have a creamy consistency to prevent “islands” from forming 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 necessary step: the glaze is required to “seal” the surface.

Procedure

Natural appearance

The Cercon ht multi-coloured technique can be applied for custom framework staining to achieve a natural appearance with thin ceramic layers.

The shade of two-piece Cercon abutments can be customized with the result that colour shift is minimized in the gingival area.

+ Cercon ht crowns + Cercon ceram love

In oral implantology, Cercon ht can be used to replicate missing hard and soft tissues in a very realistic manner.

Avoiding errors ! ! Insufficient drying times may cause framework damage. ! ! Before sintering, thoroughly remove any dust or contamination (black spots). ! ! Unsuitable instruments or excessive pressure may destroy the unsintered framework. ! ! Dry on a suitable surface in order to prevent the stain from running. Tissue is not suitable. !! Too strong staining may be caused by excessive dipping or staining times with the liquid. ! ! Metal surfaces or oxide contamination may cause framework discolouration.
