Cercon ht

n io t ra e n ge ia n o c ir z t x e n e h T

When light can partially pass through an object, this is called translucency.

Re-creating the natural translucency of teeth is one of the most difficult challenges for developers of dental materials. Cercon ht combines 10 years of CerconŽ safety and reliability with contemporary expectations of a natural-looking translucent framework base – without compromise.

Fully contoured restorations and restorations veneered with DeguDent veneering ceramics now both comprise complete treatment concepts for all indications.

Kind regards, Your sirius team

Dental materials are called translucent when some light can pass through them without them being transparent.

The Cercon ht treatment concept

Each restoration is like a fingerprint. Each is unique. No two are the same. The excellent Cercon ht performance gives us the flexibility to meet the demand for uniqueness in nearly any situation.

The Cercon ht treatment concept

The comprehensive anatomy library (3Shape) in connection with the top-of-the-line Cercon brain expert milling strategy delivers milling results that can be used directly without much finishing. The Cercon ht treatment concept is the most convincing concept for many indications.

Finishing unsintered frameworks is a very delicate task. Tools must be selected carefully to avoid damaging the framework. Minor imprecisions in contour can easily be corrected. Finishing should be performed at low speeds, avoiding pressure.

Important notes ! ! Never weaken pontic connectors. !! The minimum wall thickness is 0.4 mm for crowns and 0.5 mm for bridges. ! ! Keep cutters absolutely clean to preserve the material’s favourable physical properties. ! ! Make sure that the surface has some residual roughness (chalky surface) to allow the mixed stain to enter. ! ! While finishing, do not exert 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).

The Cercon ht starter set was developed to match the requirements and specifics of Cercon ht. Highquality components offer the processing safety you are accustomed to.

Processing instructions

˅˅ Remove any contamination Thoroughly remove all contaminants such as dust or adhesives prior to staining, using appropriate liquids. Frameworks must not be steam-cleaned nor contaminated by e.g. sweat or grease from the fingers, as this may adversely affect the property of the materials and correct shade reproduction

˅˅ For staining, follow the mixing recipe on page 14 for Cercon ceram love or the mixing recipe in the November 2011 issue of sirius News for fully contoured Cercon ht Hold objects with disposable gloves or holding clasps. Use all staining liquids only once to prevent processing errors and keep the remaining content of the bottle viable.

˅˅ Avoid pooling Do not introduce “puddles” or staining liquid residue into the firing chamber to prevent serious damage and furnace contamination.

˅˅ Notes on the drying process Use infrared light with a power of approximately 150W at a distance of no more than 20 cm from the object to ensure complete evacuation of the liquid. Do not perform drying where there is a draft (e.g. near a window), as this may prevent the heat from reaching the object, resulting in incorrect drying times (see illustration). Acid storage cabinets or fume hoods can be used, provided they are run on “low”.

Until the object has been sintered in the Cercon heat plus furnace, keep all metal tools, cutters, grinders and similar at a safe distance from the liquids to prevent flash rust and pro-

cessing errors.

Limit all transition zones between the Cercon ht framework and the future veneer by a clean chamfer.

This is the only way to ensure that the ceramic material achieves the desired compressive stress and provides adequate support for the ceramic veneer.

17

Veneering preparations

Air-abrade the areas to be veneered with aluminium oxide (110 µm/max. 2 bar) and clean the object with a steam cleaner. ˅˅ Make sure to use only oil-free compressed air

s n io t a u t si al n io t p e c x e In There are situations in which a severely discoloured tooth or core must be masked to avoid shade discrepancies occurring in different areas of a single-thickness veneer despite a standardized technique.

In these exceptional cases, use the Cercon ceram love liner as per the manufacturer’s instructions and cover the critical area locally.

Apply the mixed Cercon ceram love Custom Dentin directly to the framework. This lets you either support the value of the desired shade or modify it as needed. Custom Dentin is a mixing recipe based on extensive experience at sirius ceramics; it is not a product sold on the market. For the appropriate mixing recipe, see page 23.

˅˅ 16 + 2 bleach shades ˅˅ Less space required per tooth ˅˅ Simple mixing recipe ˅˅ Shade-adaptive multi-color framework for more reliability ˅˅ Standard or custom implementation ˅˅ Safe veneering

The Cercon ht multi-color mixing recipes were tested by dental technicians for each individual shade and evaluated using actual ceramic buildups with Cercon ceram love.

21

The Cercon ceram love concept is based on using a minimum of component shades. Any intermediate shades or transitions are first analysed against the comprehensive shade wheels and subsequently mixed at a 1 : 1 or 1 : 2 ratio following a simple mixing recipe.

This allows the Cercon ceram love shade system to produce excellent results with a manageable number of components.

If you want, you can obtain any additional effects or details or even your own personal mixes by following the instructions and using the tools.

For obtaining a precise dosage, we recommend an approach dispensing device (sirius ceramics/ART 70100).

This device dispenses the correct amount of powder, ensuring reproducible results. Two different dosage tips can be used to accommodate different dosage needs.

* The values listed here are intended for orientation only and should be regarded only as guidelines. Your firing results may differ.

All firing results depend on the performance of the furnace used, which in turn depends on the make, model and age of the furnace. Therefore, the guideline values will have to be adapted individually for each firing.

We recommend running a test firing cycle to evaluate the performance of the furnace used. We have compiled and checked all values and other data with great care. However, we cannot be liable for your results under any circumstances. For all firing tables: The firing temperature must be adjusted to the number of units fired. Five to ten units require an increase by 5°C to 10°C; more than ten units require an increase by 10°C to 20°C.
