Product Description

VASDEN Custom Special Offer Dental Material Metal Alloy Cocr Dental Cobalt Chrome
Dental porcelain metal : soft steel nickel chrome with beryllium alloy beryllium-free, nickel chrome alloy cobalt chrome alloy, nickel beryllium free cobalt chrome partial denture alloy broken partial denture alloy
This is a high-quality non-noble metal alloy used to make PFM (porcelain-fused-to-metal) crown and bridge. It has been a trustworthy alloy universally accepted by the whole world for 15 years.

High resistance to corrosion;

Biological compatibility assessed and certified by inspection organization;

Stable physical properties;

Strong bonding force between me[x]tal and porcelain;

Low expansion coefficient, stable, safe and reliable;

Bubbles and cracks in porcelain are greatly reduced through manufacturing in high vacuum environment;

Instructions for Use:

Wax Pattern

The thickness of the wax pattern shall be at least 0.4 mm and the thickness of the casting after sanding and sand blast shall be at least 0.3 mm. In case of dental crown or long bridge that contains high percentage of me[x]tal, a me[x]tal reservoir can be installed after proof by experiment.

em[x]bedment

Compatibility is available to the market generally accepted phosphate Ni-Cr porcelain em[x]bedment. Application shall be put under strict control according to the instructions provided by the em[x]bedding material manufacturers.

Casting

This alloy can be cast with flame or through HF process. Porcelain crucible is selected. Do not overheat during fusion. It's better not to wait till the film is broken so as to avoid shrinkage cavities, bubbles, etc. It is suggested that only new me[x]tal be used to keep accuracy and nice outlook of the casting. For recycled application, only 50% of used me[x]tal can be added.

After the cast ring is opened

To cut off the sprue according to the standard, sand the casting and then carry out sand blast;

Cleaning and Oxidation

Clean the sand blasted casting with ultrasonic wave or steam and then carry out oxidation to the casting in the porcelain furnace in complete vacuum at 980ºC. Time of holding is nor necessary for single crown and small bridge. If the bridge is too long, please hold for 2 minutes to avoid deformation.
