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
Applying the Model Separator

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.

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
1. Roughen the area intended for repair, add-on or tissue tint using a
carbide bur. Extend the roughening 1mm beyond the area of repair,

add-on or tissue tint.
2. If necessary, apply Model Separator to the repair area of the model
and place the restoration back on the model.
3. Wet the roughened surface by brushing a thin layer of sealer onto the
prepared resin surface.
4. Extrude a small amount of dentin or enamel resin (as needed) onto a
palette; then use the electric spatula to apply the resin to the repair/
add-on area. For the tissue tint, use the electric spatula to apply the
resin to the desired area.
5. Allow to cool for 2 minutes.
6. Use a brush to apply a thin layer of the sealer to the repair/add-on.
Immediately clean the brush with acetone, or place the brush in a dark
area.
7. Cure in the Enterra, Triad 2000 or the Eclipse Processing Unit using
the INITIAL CURE on Table 1.
8. Finish according to previous techniques.
RADICA DIAGNOSTIC
Radica can also be used as a diagnostic and provisional material at the
same time. This will allow for a very esthetic diagnostic presentation,
and the case will already be prepared for provisionals.
1. Prepare the model using a uniform 1.0mm reduction.
2. Wax the case to full contour, optimizing the contours.
3. Make a mould using the Matrix Putty.
4. Fabricate the Radica provisional as previously indicated. Follow all
steps as listed in the Provisional Fabrication section.

BUILD UP OF A TOOTH ON A DENTURE BASE
NOTE: Radica can be bonded to conventional acrylics or Eclipse resin
using the following procedure. To prevent any distortion of the denture
base resin, be sure to have the appliance on the model when curing.
1. After the denture base is fully cured, use a course carbide bur to
roughen the surface. Steam clean or scrub under running water to
remove any debris. Allow to dry thoroughly.
2. Apply a thin coat of the VLC Sealer. Allow to bench set for 2 minutes.
Do not cure.
3. Apply the Radica to the desired area using the electric wax pencil.
Allow to fully cool.
4. Apply a thin coat of the VLC Sealer and cure for 5 min (Initial) in the
Enterra unit, or 10 min in the Triad 2000, or 3 min (Initial) in the Eclipse
Processing Unit.

13
5. Finish and polish the denture and Radica restoration using a rag wheel
with pumice and polishing compound.
DELIVERING THE RADICA RESTORATION
Ensure all internal areas are clean. If necessary blast with aluminum
oxide at 20 psi. Also clean model to remove all traces of the separator
before reseating for delivery to dentist.

TIPS, TRICKS & TROUBLESHOOTING
Can a handheld tack light be used with the
Radica Provisional?
• Yes – but only to "tack" the resin into position. You
still must follow with a full curing cycle.
Cannot remove the cured provisional from
the model.
• Did not use enough model separator.
• Undercuts on the model.
• Sealer was overlapped onto the model during
application.
Gray streaks/discoloration in the completed
restoration.
• Used an electric wax pencil with tips that were not
nickel or chrome coated.
• Used a warm instrument from an external heat
source.
Voids or porosity in my cured resin. • Air was trapped in the resin when expressing the
resin into the silicone matrix.
• Surface was not properly prepared prior to doing
an add-on procedure.
Shades are o. • Too much or too little enamel used in relation to
the dentin.
• Used the wrong enamel.
• Used excess eect dentin.
• Improper positioning of the model in the curing
unit when curing (Triad 2000 only).
• Did not use an approved curing unit.
• Dentist used the wrong reline resin.
Cannot express the resin from the syringe. • The syringe was not in the syringe warmer long
enough.
• The syringe was not fully inserted in the syringe
warmer.
• The tip of the syringe was left o and the material
polymerized.
Final provisional did not appear to have the
proper strength.
• Did not use the correct curing cycle.
• Did not use the recommended curing unit(s).
• Did not use the recommended connector size.
• Improper positioning of the model in the curing
unit.
• Walls of the restoration are too thin.
• Did not use enough separator on model.
Surface of the provisional is rough after
curing.
• VLC sealer started to cure prior to applying to the
surface.
• Surface not smooth prior to the sealer/glaze
application.
• Application brush was contaminated.
• Continued brush strokes after the sealer started
to dry.
Surface has lost its detail. • VLC Sealer was applied too thick.
Observed blue tint on restoration due to
Matrix Putty.
• Insucient mixing of base/catalyst.
What is the best choice of Reline Material? • Choice of reline material and cement will aect
longevity. Best results are also obtained with
frequent recalls and supervision through the treat-
ment sequence.
• Best results are also obtained with more Radica
and less reline. Preferably all Radica.
• Reline Materials: Triad® VLC Provisional Material,
Biolon® C&B Resin (DENTSPLY Trubyte), Tempo-
rary Bridge Resin, Integrity® Temporary Crown and
Bridge Material.
