INSTRUCTIONS FOR USE

MODELLATION
Design the framework in a reduced anatomic shape taking the planned veneer into consideration.
Single crowns require a thickness of minimum 0.3 mm; abutment crowns thickness a minimum of
0.5 mm. Make sure the framework demonstrates adequate stability of shape. Avoid sharp angles.
Design the connector areas to be adequate for the position and alloy being used. To increase the
strength of a bridge in a cantilever situation, maximize the height of the connector.
SPRUING
Provide the modeled bridge framework or coping with sprues of a suitable size. Use the direct or
indirect technique being sure that the reservoir is positioned in the heat center. The connection
sprues between the reservoir and the coping should be 2.5-3.0 mm in length and width.
INVESTMENT
Weigh the wax pattern including the sprue to determine the quantity of the alloy to be used. (See
wax conversion sheet/formula: weight x density = gr. of alloy). Use investment following the man-
ufacturer`s instruction.
BURN-OUT
The suggested burnout temperature: 750-820C/1380-1510F
MELTING AND CASTING
Use a separate carbon/ceramic crucible for each alloy and preheat the crucible (ceramic) in the
burnout furnace. Used and new alloys must be in a ratio of 1:1. Depending on the type of cast-
ing machine, follow the manufacturers instructions for use. If you use Ivoclar Vivadent Magic
Wand, set propane to 0.35 bar/5 psi and oxygen to 0.7 bar/10 psi pressure. Keep the alloy in the
reducing atmosphere of the flame between the inner and outer cones. Do not use flux. After
casting bench cool to room temperature.

Casting Temperature: 1285-1345C/2345-2455F

METAL PREPARATION
Carefully divest and clean the object with AL

O

3

. Do not use a hammer for divesting the object to

prevent deformation. Finish the framework with carbide burs or with ceramic-bonded grinding
instruments. Avoid inhalation of dust during grinding!
OXIDATION
Blast surface with 50-100 micron AL

2

O

3

at max. 4.5 bar/65 psi pressure before oxidation.

Subsequently, clean with ultrasonic or steam. Place the object on the firing tray and provide ade-
quate support. Place the tray in a porcelain furnace set at a low temperature of 650C/1200F and
increase the furnace temperature to 950C/1740F without vacuum with 5 min. hold time at top
temperature.
HEAT TREATMENT

Hardening: 600C/1110F for 30 minutes; air cool.

SOLDERS AND FLUXES
Design the soldering patty as little as possible and preheat it in the furnace at approxi-
mately 600C/1112F. The soldering gap should be the same thickness as the soldering strip. Allow
the object to cool slowly after soldering.

Pre-Solder: Special High Fusing White Ceramic Solder, High-Fusing Bondal Flux
Post-Solder: Low Fusing White Gold Solder, Bondal Flux
Laser weld material: Laser Ceramic White

POLISHING
After glazing remove oxide and flux residue and finish/polish the framework with rubber finishers/
polishers.
INDICATIONS
Recommended for onlays, 3/4 crowns, telescope crowns, conus crowns, posts, short and long span
bridges, PFM crowns, implant superstructures, partial dentures.
CONTRAINDICATIONS
For patients with known allergy/sensitivity to any major or minor constituents of this alloy, consul-
tation with a physician is recommended.
SIDE EFFECTS
In individual cases, sensitivity or allergies to components of this alloy may occur.
INTERACTIONS
Galvanic effects may occur between different alloys in the same oral environment.
For additional information look into the alloy property chart.

INSTRUCTIONS:
1.Select a sprue with a reservoir equal to or larger than the thickest cross-section of the restoration.
2.Maintain the reservoir(s) within the heat center of the investment; keep the restoration(s)

approximately 5 mm from the end of the investment and no closer than 5 mm from the sides.

3.Make sure that the sprue is connected to the thickest part of the restoration.
4.The connection between the sprue and the restoration should be flared (“trumpet” configura-

tion); eliminating turbulence of the alloy (causing investment erosion) and facilitating an undis-
turbed flow of alloy during casting and solidification.

5.Maintain proper alloy weight in order to eliminate the negative effect of a too large button dur-

ing solidification. The rule of thumb for proper alloy weight determination is: total wax weight
x specific gravity of the alloy = proper alloy weight.

SUGGESTIONS:
1.Thickness and design of wax pattern: follow your manufacturers instructions.
2.Use chill-vents when casting heavy and/or large restorations.
