ADORBOND CC is a biocompatible cobalt-chromium based
non-precious alloy for bake-on technique.
It is free from nickel, beryllium and gallium.
The alloy complies with the requirements of both the
DIN EN ISO 9693 standard for metal-ceramic systems and the DIN 22674 for non-precious metal alloys.
Thanks to its low hardness of 285 HV 10,
ADORBOND CC features good drilling, milling, and polishing properties which is an advantage for any primary treatment.
Wall thickness (in wax) should not be less than 0.35 mm diameter. Apply indirect spruing. For the casting sprues use round wax wires with a diameter of 2 to 2.5 mm for single-unit crowns and of 2.5 to 3 mm for bridges. For large structures with 4 pontics and more use a feed channel of 3.5 to 4 mm, for solid connecting links use up to 5 mm.
Investing and Casting
Phosphate-bonded crown and bridge investment materials can be used. The preheating temperatures range between 850 and 900 °C. The Holding time after the final temperature has reached is min. 30 minutes. It is imperative to follow the relevant casting machine manufacturer’s instructions for use. Use always a new ceramic crucible for ADORBOND CC to avoid contamination which may occur by residuals from previously used alloys. Clean crucible after every casting. Casting should be started after all cylinders are completely melted and the melt shows a uniformly light appearance. With a loose circular motion of the flame in the reducing zone, continue the melting process until the metal is seen to move under the pressure of the flame. Allow casting ring (muffle) to cool down to hand temperature and divest.
The commercially available dental ceramics for cobalt-based dental alloys can be used, such as Vita, Ivoclar, DeTrey Dentsply, or Ducera. Observe the respective manufacturer’s instructions for use.
1. Sandblast the framework surface in a pencil blaster with 100 or 250 µm aluminium oxide.
2. Clean the framework either with distilled water in an ultrasonic cleaner or with degreasing agent ethyl acetate.
3. Carry out oxide firing for 5 minutes at approx. 960 °C. Always sandblast the oxide layer again after the oxide firing.
4. Apply the first opaque firing thinly. Apply uniform cover only at the second opaque firing. Always allow paste opaque to cure before heating.
5. Ceramic build-up according to the porcelain manufacturer’s instructions.
6. Slow cooling after each dentine, correction and glaze firing at a cooling phase of up to approx. 750 °C is required.
After completion smoothen the unveneered sections of the framework by means of a rubber polisher and polish to a high lustre using either a polishing paste for cobalt-based alloys or rotating polishing tools.
Soldering and Welding
We recommend using ADOR CC cobalt-based solder and high-temperature flux for soldering after firing and ADOR Co-Cr laser wire for laser welding.
Metal dust is harmful to your health. When finishing and blasting use a suction/extraction system.
