Nickel-chrome bonding alloy for high-melting ceramic compounds

ADORBOND CN is a dental metal-ceramic alloy on the nickel basis ADORBOND CN is free of cadmium, beryllium and lead and, according to EN ISO 22674, corresponds to type 3 for fixed multi-unit dentures.

Processing recommendation
Carry out the wax-up as usual but avoid wall thickness less than 0.35 mm diameter. Cast the channels indirectly. For the cast channels use round wax wires with a diameter of 2 to 2.5 mm for single crowns and of 2.5 to 3 mm for bridges. For large structures with 4 units or more use a distribution channel (casting beams) of 3.5 to 4 mm, for solid intermediate links use channels up to 5 mm.
Embedding and casting
Phosphate-bonded crown and bridge embedding compounds are suitable. The preheating temperature is 850-900 °C, holding time at the final temperature is min. 30 minutes. Follow the manufacture’s operating instructions for the casting machine. Always use a separate ceramic crucible for ADORBOND CN to avoid contamination by other alloys. Clean crucible after each casting. Do not overheat the alloy. Casting can be started after all cylinders are completely melted and the melt becomes uniformly bright. Always melt with the flame in the reducing zone with circular movements above of the burner. Allow muffle to cool down to hand temperature and bed out without hitting the cone.
Ceramic firing
The commercially available normal-fusing bonding ceramics for non-precious bonding alloys with a suitable coefficient of thermal expansion (CTE) can be used. Please observe the corresponding working instructions and the information provided by the ceramic manufacturer regarding the cooling rate after firing.

After bedding out:

1.      Separate channels and do the finishing work. Carbide cutters are recommended for this.

2.      Blast the framework surface in a stylus sandblaster with 100 mm or 250 mm aluminium oxide.

3.      Clean the framework either with distilled water in an ultrasonic cleaner or with degreasing agent ethyl acetate.

4.      Oxide firing (optional for checking the surface) should be about 5 min at approx. 960 °C under vacuum. Always sandblast the oxide layer again after firing and degrease.

Note: cleanliness of the surface is the best protection against bubbles in the ceramic.

5.      Apply a thin layer of Washbrand, fire only the second base coat for an even coverage.

Always let paste opaque dry for 5-10 minutes at 600°C before heating.

6.      Ceramic firing and cooling according to the manufacturer’s instructions.

7.      In case a long-term cooling is necessary, carry out a cooling phase to approx. 750 °C after each dentine, correction and glaze firing.

Finishing up

After firing the ceramic, rubberize unveneered framework parts and polish to a high gloss with a polishing paste for dental alloys or with rotating polishing tools.

Soldering and welding

Soldering before firing with the ADORBOND CC-Lot and high-temperature flux. The width of the solder gap should be 0.05-0.2 mm. Laser welding with the ADORBOND CC-Laserdraht.

Safety instructions

Metal dust is harmful to your health. Use suction when handling the powder, by finishing works and blasting. Hypersensitivity to the alloy components should be taken into account. In case of suspected intolerance with certain alloy components, the product should not be used. Product contains nickel!
