WARNINGS
Radica Dentin, Enamel, Eect Dentin
Radica contains components which may cause allergic skin reaction
and serious eye irritation. Suspected of causing cancer by inhalation.
Suspected of damaging fertility. Avoid breathing dust or fume. Work in
a well ventilated area. Wear protective gloves, eye protection (safety
goggles recommended) and protective clothing. Wash thoroughly with
soap and water after direct skin contact In case of contact with the
eyes, rinse with large quantity of water for several minutes. If eye or skin
irritation occurs, get medical attention.
Radica Sealer
Sealer (liquid/vapor) is highly flammable. Keep containers tightly
closed and use/store away from heat or sources of ignition. Sealer
contains components which may cause skin irritation and / or allergic
skin reaction. Wear protective gloves, eye protection (safety glasses
recommended) and protective clothing. Wash thoroughly after handling.

2
If eye or skin irritation occurs, get medical attention. Suspected of
damaging fertility or the unborn child. Avoid breathing mist, vapors or
spray. Use in a well-ventilated workspace to avoid inhalation. Harmful to
aquatic life with long lasting eects. Avoid release into the environment.
Dispose of contents and containers in accordance with local and national
regulations.
Radica Stain
Component in Radica Stain is suspected of causing cancer. Wear
protective gloves and eye protection (safety glasses recommended).
If concerned about exposure, get medical attention. Use in a well-
ventilated workspace to avoid inhalation. Dispose of contents and
containers in accordance with local and national regulations.
PRECAUTIONS
1. Keep Radica Sealer bottles tightly closed when not in use. Sealer
Material is volatile and highly flammable. Keep away from heat, sparks
and flames.
2. The Radica system products (dentin, enamel, eect dentin and sealer)
are light sensitive! Minimize exposure to light and keep the lid on the
container to maintain its eective use.
3. Store in a cool, dry area; 60°- 80°F (16° - 27°C) is recommended.
4. Use the Radica System in a well-ventilated workspace.
5. Avoid inhaling grinding dust. Use suction and adequate industrial
ventilation.
6. Restorations with mesial-distal spans greater than 38mm cannot be
processed in the Triad® 2000 curing unit. Restoration/model with a
height greater than 40 mm should not be processed in the Enterra®
VLC Curing Unit.
7. When making adjustments to repair or refinish restorations by a
dentist intraorally, be sure to fully remove the cured sealer layer.
Repolish using manual polishing techniques after repair.
8. Dispose of material in accordance with national and local regulations.
ADVERSE REACTIONS
The Radica System contains components which may cause skin dryness,
sensitization (allergic contact dermatitis), serious eye irritation or other
allergic reactions in susceptible persons. Certain Radica materials may
cause cancer by inhalation or damage fertility.

EQUIPMENT
Radica Syringe Heater
The Radica resin must be heated prior to application. Plug in the
Syringe Heater and turn on the unit. The heater is preset to 140°-
147°F (60˚-64˚C). Allow the heater to warm up for about 30 minutes.
Approximately 10 minutes prior to use, place the necessary dentin and
enamel syringes in the heater slots. The Radica syringes may remain in
the heater during the day, but should not remain heated for an extended
period of time.
Electric Wax Pencil
The electric wax pencil should be used for manipulating the resin. The
special nickel-plated tips were designed to prevent any discoloration
of the resin. Do not use other electric wax pencils unless the tips are
chrome or nickel-plated steel. Ensure the wax tips remain clean. Do
not use hot instruments that have been warmed with an external heat
source.
LIGHT CURING UNITS
Be sure to use the Enterra®VLC Curing Unit, Triad®2000 Curing Unit
(maximum of 38mm span in the Triad 2000), or the Eclipse®Processing
Unit.
To ensure an optimum cure, follow these guidelines:
1. When using the Enterra, the model + restoration should not exceed
40mm in height as indicated by the perforated maximum height line
on the Enterra unit.

4
2. When using the Triad 2000 VLC Unit, appliance must be placed
on the center of the turntable. Position the turntable height so the
bottom edge of the device lines up with the lowest edge of the Lamp
Access Door.
Instructions:
MATRIX PREPARATION
1. Ensure that the teeth that are to be prepared are clean and free of
any debris.
2. Fill in any edentulous areas requiring a provisional with a denture
tooth.

3. Use the Radica Matrix Putty and mix the base and the catalyst in a
one-to-one ratio until thoroughly mixed.
4. Apply the putty to the area of the model requiring the provisional
restorations. Be sure to also capture the adjacent teeth, and extend
the putty down at least 2mm past the marginal area.
5. Allow the Matrix Putty to harden. Remove it from the model.
6. Using a sharp instrument, remove the Matrix Putty to within 2mm of
the margin area.
MODEL/DIE PREPARATION
Note: Proper die reduction is important. Over reduction will result
in a provisional that is too thick, and will need to be hollow ground
prior to insertion. Minimum connector size is 4mm x 5mm.
1. Select a Midwest®HP 1558 carbide bur that has a diameter of 1.0mm.
Make depth cuts in the die stone as a guide.
2. Use a die saw or a diamond disk and open the adjacent contacts 1mm.
Be careful not to damage the adjacent tooth. Use the carbide bur to
reduce the required stone die by approximately 1.0mm.

PROVISIONAL FABRICATION
1. Express a small amount of the pre-heated enamel resin into the incisal
area of the matrix. Use the electric spatula to spread out the resin
and remove any excess. Excess resin will prevent the matrix from fully
seating. Allow the resin to air cool about one minute.
2. There are four eect dentins: red-orange, yellow-orange, deep red
tissue tint and tissue tint. They can be used to increase the chroma of
a tooth in a specific area such as the gingival or occlusal or fill in for
tissue voids around the gingival margin.
Use a saw on the
interproximals

3. Quickly express enough dentin to fill the remaining voids in the matrix.
Immediately place the matrix onto the prepared model, allowing the
excess material to escape around the margins.
4. Allow the material to set approximately 2-3 minutes.
5. Remove the matrix putty from the model. If necessary, additions may
be made by using the electric spatula and applying some enamel or
dentin resin.
6. Excess resin may be easily removed using an instrument. Connector
should be U-shaped (not V-shaped or pointed) and the size should be
at least 4 X 5mm.
7. Use a brush to apply a thin layer of the sealer. Do not paint sealer
onto the model while applying it to the Radica crown or bridge. If
overlapped onto the model, the restoration will be dicult to remove
from the model after curing.
Note: Immediately clean the brush with acetone, or place the brush in
a dark area.
8. Following the placement guidelines, put the restoration/model into the
Enterra, Triad 2000, or the Eclipse Processing Unit, and do the INITIAL
CURE according to Table 1.

9. For crowns, proceed to FINISHING THE PROVISIONAL, STEP 1.
10. After curing, allow the model/restoration to return to room
temperature before removing the cured restorations. This may be
accelerated by placing the model in cold/ice water.
11. Use a brush to apply a thin layer of the sealer to the bottom of the
pontic.
12. Place the bridge, upside down, on the Enterra or Eclipse Processing
Unit turntable or on the center of the Triad 2000 turntable and cure
according to the PONTIC CURE step on Table 1.

FINISHING THE PROVISIONAL
1. Use an instrument to remove the provisional from the model and do
any additional contouring.
2. To clean the provisional, blast all internal and external surfaces with
aluminum oxide at 20 psi. Steam clean all surfaces; then dry.
3. There are five stains: brown, blue, white, orange, and olive. If stains
are required, place a small amount of the stains on a palette and mix
with a small amount of the sealer PRIOR to applying sealer to the
restoration.
4. Use a brush to apply a thin layer of the sealer to the external surfaces.
Immediately clean the brush with acetone. If stains are going to be
used, IMMEDIATELY apply stains to the provisional using a fine brush.
5. Cure the sealer in the Enterra, Eclipse Processing Unit or the Triad
2000 unit according to the SEALER CURE on Table 1.
6. Radica provisionals may also be mechanically polished using bung
wheels and abrasives.
REPAIRS / ADD-ONS / TISSUE TINT
