ADORBOND CC Plus Powder 10-30 μm is a cobalt-based dental metal-ceramic alloy in the form of dental powder. ADORBOND® CC PLUS Powder 10-30 μm is free of nickel, cadmium, beryllium and lead and complies with EN ISO 22674 type 5 for applications with thin cross-sections that are exposed to very high forces, e.g. removable partial dentures, clasps, thin veneered single crowns, fixed full arch dentures or bridges with small cross-sections, bars, attachments and implant-supported superstructures. ADORBOND® CC PLUS Powder 10-30 μm can be used both as a model casting alloy and as a metal-ceramic alloy.

Safety instructions

Metal dust is harmful to health! Avoid dust formation and inhalation of the powder! Use suction when handling the powder, working out and blasting. Wearing of tight-fitting safety goggles, protective gloves, FFP3 respirator and protective clothing is recommended. Observe safety data sheet. Hypersensitivities to components of the alloy must be taken into account. In case of suspected incompatibilities to individual elements of this alloy, it should not be used.

Warranty

These technical application recommendations are based on our own tests and experience and can therefore only be regarded as guidelines. The dentist or dental assistent himself is responsible for the correct application of the product.

Instructions for Use metal-ceramic alloy ADORBOND CC PLUS Powder
10 μm – 30 μm

ADORBOND CC PLUS Powder is a dental metal-ceramic alloy based on cobalt. ADORBOND CC PLUS Powder is free from nickel, cadmium,
beryllium and lead and fulfils the standards of EN ISO 22674 type 5 for appliances in which parts require the combination of high stiffness and strength, e.g.
thin removable partial dentures, parts with thin cross-sections and clasps ADORBOND CC PLUS Powder can be used as a partial denture alloy as well as a
metal-ceramic alloy.

Recommendations for Use

Design
The design is carried out with suitable CAD software in consideration of dental rules. Wall thickness after finishing of the object: at least 0,3 mm. Design the
connector as strong and high as possible (height: at least 3,5 mm, width: at least 2,5 mm).

SLM-Process
Avoid dust production while opening the powder container, transportation and filling into the SLM system! Use a suitable SLM system for the particle
distribution of ADORBOND CC PLUS Powder and carry out the SLM-Process according to the manfucturer’s instructions for the SLM system. Non
melted powder can be reused but should be sieved with a powder sieve (80 μm) or ultrasonic sieve (55 μm) first. Melted powder cannot be reused by e.g.
casting.

Shot Peening
Blast the production platform with spherical ceramic material with  0,125-0,250 mm and 2,5-3,5 bar until a uniform saturation of the surface is visibly
achieved.

Stress Relief Heat Treatment
The heat treatment needs to be carried out in a special furnace under argon atmosphere. Place the production platform in an inert gas box with an argon flow
of 1-2 L/min and put the box into the cold furnace. Then:
1. Within 60 min heat up to 850 °C and hold the temperature for 60 min.
2. Let the platform cool down. Open furnace door earliest at 600 °C or lower temperature, remove the inert gas box and stop the argon flow.

Firing of Ceramics
Use commercially available dental ceramics for cobalt based metal alloys with a suitable linear thermal expansion coefficient. Please follow the associated
work instructions and cooling schemes given by the ceramic manufacturer. After the heat treatment and cooling down:
1. Remove restorations from the plate using a band saw, rotating instruments or pliers. Use pliers to remove the rest of the supports. Carbide cutters
are recommended for finishing of the object.
2. Sand blast the surface by use of a pencil-blaster with aluminium oxide 100 μm or 250 μm.
3. Ultrasonically clean the frame in distilled water or degrease with ethyl acetate.
4. The oxide firing is optional, to be done at about 960 °C under vacuum for 5 minutes. Always remove the oxide layer after oxide firing by sand
blasting with aluminium oxide and degrease again.
Note: A clean surface is best to avoid bubbles in ceramics.
5. The opaque is applied on the surface by a first thin wash firing and a second evenly covering opaque layer.
Before firing always let the opaque dry for 5-10 minutes at 600 °C.
6. Firing and cooling should be carried out in accordance to the ceramic manufacturer’s instructions.
7. After every firing step (dentine bake, build-up and glazing) cooling phase until ca. 750 °C.

Finishing
After firing of the ceramic, polish the frame with suitable grinding and polishing instruments for dental alloys up to high gloss.

Soldering and Welding
Soldering before firing of the frame can be carried out with commercially available solders und high temperature flux. The width of the solder gap should be
0,05-0,2 mm. For welding with a laser use suitable commercially available metal welding wires

Instructions for Use partial denture alloy ADORBOND CC PLUS Powder
10 μm – 30 μm
ADORBOND CC PLUS Powder is a dental partial denture alloy based on cobalt. ADORBOND CC PLUS Powder is free from nickel, cadmium,
beryllium and lead and fulfils the standards of EN ISO 22674 type 5 for appliances in which parts require the combination of high stiffness and strength, e.g.
thin removable partial dentures, parts with thin cross-sections and clasps. ADORBOND CC PLUS Powder can be used as a partial denture alloy as well as
a metal-ceramic alloy.
