TECHNICAL FEATURES

Our zirconia works are biocompatible and made from disk of tetragonal and polycrystalline zirconiumdioxyde (3Y-TZP-A).

SPECIFICATION

The yttrium oxide stabilizing protects the material against cracks and increases the tensile and compressive strength.The special grain size allocation inside the material and the added aluminium oxide enhances the material mechanical resistance. The required thickness of the works is ideally superior to 0.5 mm.The outstanding mechanical characteristics, excellent chemical durability and the combined unbeaten biocompatibility make our zircon material the ideal material. Our zircon is a medical device class IIa appendix IX 2.1 rule 5 according to the RL 93/42 EWG - marked 0482 and meets EN ISO 602 and EN ISO 6872 standards.

INSTRUCTIONS FOR USE

FinishingThe construction can be fitted to the model by a wet milling process with diamond-coated burs.Metal burs should not be used.Overheating should be avoided.

Specifications - Full ZirconiaPre-polishing with a lens for ceramic fine grain. The occlusal surface must always be very carefully polished until a mirror finish. Use rotary instruments at an average speed of 10 000 rpm.Final polishing at 5000 rpm with buffalo style brush.Deep lines and rough surfaces can cause excessive abrasion of antagonist teeth and should therefore be avoided.In the case of very thin walls, the color rendering may be lighter. It is important for the dentist to use the appropriate cementing materials. It is recommended to use a modified polymer, translucent, self-adhesive or composite cements.

Porcelain bondingAll known brands of zirconium frames can be used as long as their thermal expansion coefficient is approximately 10x10-6 K-1.We generally advise you to:• Clean the framework after final shaping with hot steam.• Cover the zirconium frame completely with a layer of ceramic.• Follow the instruction for the material of your choice.

TECHNICAL FEATURES

TECHNICAL FEATURES

The cobalt-chrome alloy was developed in close colla-boration with dental technicians and is a cobalt chrome molybdenum-based superalloy designed specifically for porcelain firing in metal restorations (PFM). This material has a coefficient of thermal expansion of 14.0 - 14.5 x 10-6 m/m °C and thus provides optimum adhesion of commercial ceramics.

CONTRA-INDICATIONS

Don’t use cobalt-chrome in case of proven incompatibility with one or more metals in the alloy. In rare cases, the oc-clusal contact with other alloys may cause electrochemical reactions.

INDICATIONS

Cobalt-chrome is a cobalt-based metal alloy used to manu-facture by laser fusion dental restorations (crowns, bridges etc..) designed to receive a ceramic coating.The required thickness of designs is ideally 0.5 mm. Its com-position complies with the EN ISO 22674 : 2006 standards - Type N dental alloy.It also fulfills the chemical and thermal requirements of EN ISO 9693 for CoCr PFM dental materials and the require-ments of EN ISO 7504 and EN ISO 10993 regarding the biocompatibility and cytotoxicity of dental materials. Co-balt-chrome powder is a medical device of class I I in a accor-dance with the norm 93/42/CEE appendix IX, rule 8 and has also been certified according to CE regulations (CE 0537).

TECHNICAL FEATURES

Our CoCr alloy for machined works is a high quality Co-balt-Chromium which does not contain any precious metal.Thanks to its low thermal conductivity, its good adhesion to ceramic, its optimal physical properties, our CoCr alloy for machined works answers to the patients’ demands as well as to the practitioners and the prosthodontic technicians. Its use is easy.

INDICATION

Our CoCr alloy for machined works is intended for the pro-duction of crowns and bridges for anterior and lateral teeth as well as for primary or secondary elements with telescopic technique. Large elements are also feasible.

PRECAUTIONS

For optimal results, carefully respect the implementation ins-tructions of our CoCr alloy for machined works.During the machining, you should wear safety clothing (mask, gloves, apron etc…) intended to be used for that purpose. Metal dust is harmfull to your health, use suitable air extrac-tion system when grinding or sandblasting. Sensibilities to the alloy elements should be respected.

IMPLEMENTATION

Before the touch up, an aluminum oxide (110µm) sandblas-ting of the framework is necessary. The machining can be done with tungsten or diamond drills. In every case, it is ad-vised to move the handpiece in one direction only in order to prevent the metal from sheeting (which would cause bubbles with the ceramic).

CERAMICS

Use usual ceramics for CoCr alloys. Respect the correspon-ding instructions, in particular when it comes to the cooling down after firing.

PREPARATION FOR THE FIRING

1. To prepare the metal framework, sandblast with aluminum oxide (100µm to 250µm).

2. Clean the frameworks with a vapor blast or in a cleaning agent.3. Continue with a 10 minutes oxidation firing at 980°C. Af-

ter the firing, it is imperative to clean as in 1 & 2.

CERAMIC FIRING

4. Apply a thin coat of wash opaque. The slurry coat must be dried for 10 minutes before going into the oven.

5. Heat and cool off following the ceramic producer’s ins-tructions.

6. In case of a slow cool down, after each dentin baking, touching up or icing, observe the cool down phase to 750°C.

FINISHING

Prior to polishing, remove the rest of the oxide with the alumi-num oxide. First, use a rubber tip, then the brushes with a po-lishing paste for CoCr. Then clean with ultrasounds or steam.
