This new ceramic alloy is for special
low-fusing and high-expanding ceramics for bake-on technique.
It is free from nickel and biocompatible on a cobalt-chrome-molybdenum basis with outstanding corrosion resistance and good strengths properties.
This alloy features good milling, polishing and very good laser welding.
ADORBOND CLF is made in compliance with the DIN EN ISO 9693 standard.
Wall thickness (in wax) should not be less than 0.35 mm diameter. Apply indirect spruing. Guide round wax profiles with a diameter of 3.5 to 4mm in flow direction of the melt avoiding sharp angles. For large structures with 4 pontics and more use a feed channel of 0.4 mm.
Investing and Casting
Phosphate-bonded crown and bridge investment materials can be used. The preheating temperatures range between 850 and 950 °C according to the type of investment material and the casting machine. The holding time after the final temperature has reached is between 45 and 60 minutes according to the cast ring (muffle) size and filling degree of the furnace. It is imperative to follow the relevant casting machine manufacturer's instructions for use. Use always a new ceramic crucible for ADORBOND CLF to avoid contaminations which may occur by residuals from previously used alloys. Casting should be started after all cylinders are completely melted and the melt shows a uniformly light appearance. When melting with the torch, take care that the correct flame is adjusted according to the manufacturer's instructions. 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. Do not overheat. Allow casting ring (muffle) to cool down and deflask it. Sandblast the casting carefully at a pressure of 4 bar using corundum.
Commercially-available low-fusing and high-expanding standard dental ceramics can be used. Observe the relevant instructions for use. After separation of the sprues and finishing:
After completion smoothen the framework with rubber polishers and polish to high lustre using a polishing paste for cobalt-based alloys.
Soldering and Welding
Use a cobalt-based solder and high-temperature flux for soldering. For laser welding use a standard Co-Cr laser wire as filling material.
Metal dust is harmful to your health. When finishing and blasting us a suction/extraction system.
