The Colourful World of Labels
Paste Opaque
Provides a thin coat for the metal substructure and ensures good adhesion
between the substructure and the
ceramic. The opaque also ensures true
shade identity of all
-type ceramics.
Powder Opaque
Provides a thin coat for the metal substructure and ensures good adhesion
between the substructure and the
ceramic. The opaque also ensures true
shade identity of all
-type ceramics.
To use, mix with Optimix powder
opaque liquid.
Dentine
For constructing the dentine core of
the restoration and enhancing the primary shade effect.
Dentine Modifier
Lends a more individual nuance to the
dentine core in a variety of shades.
Chromatix™
(Chroma Dentine)
Chromatix™ materials are
dentine modifiers and are used to
control and individualise chroma and
opacity. Chromatix™ has a slightly
higher opacity than the dentines, plus
a slightly higher degree of chroma.
Opale Incisal
Opale Incisal provides a natural
opalescence even with multiple firings. Opale Incisal can be mixed with
regular incisal material or used on its
own. “Light dynamics are a standard
asset for us.”
Opale Effect
In contrast to the standard opale
incisals, which are colour-keyed, the
Opale Effect materials are characterised by linearly diminishing translucency
and opalescence. Moreover, analogous
to the diminishing translucency, the
fluorescence of these materials shows
a linear increase. This makes them
ideal for simultaneously enhancing
and regulating the brightness of the
veneer in the incisal area.
Shoulder High /
Correction
Shoulder High: for aesthetic, metalfree ceramic shoulders. Shoulder
Correction: for low-melting corrections to the ceramic shoulder, e.g.
after glazing.
Transpa Clear /
Transpa Neutral
Translucencies with a wide variety of
characteristics can be created using
Transpa Clear / Transpa Neutral. As
well as adding a nuance to incisal
areas, it can be used to create
translucent incisal edges.
REFLEX® Stain
Incisal
For imitating the natural incisal enamel.
The descriptions of the incisal refer to
specific shades. Incisal 2 is needed, for
example, to produce an overall A2
shade when using a standard A2
veneer.
Incisal Modifier
Final adjustments, for example in the
cervical or occlusal areas, can be
carried out using Stain.
X Carving
Liquids (mixing Liquid)
X Carving Liquids are used for making
up all
-type veneering porcelain
dentines, modifiers and incisals.
They guarantee optimum modelling
characteristics and a wide processing
range together with excellent firing
properties. REFLEX® ceramics should
only be mixed with the recommended
liquids.
X Carving Liquid Retain
Slow drying liquid. Also used for
mixing shoulder masses.
X Carving Liquid Speed
Fast drying with minimum shrinkage.
X Carving Liquid Red, Yellow and Blue
The individual materials are shadecoded so that it is easier to make the
right selections when building up the
layers.
X Stain Liquid
(stain and glaze liquid)
For mixing
Liquid.
-type stains use X Stain
Paste Opaque
Thinner
For diluting REFLEX® paste opaque.
In order to ensure the best handling,
firing and bonding properties, only
this thinner may be used. Use sparingly.
Opaque Liquid
Optimix (powder
opaque mixing liquid)
Correction
This material can be used to correct
veneers which have already been built
up. The low firing temperature of
700 °C prevents any change in the
shape or lustre of the veneer.
Use for mixing REFLEX® powder opaque. In order to ensure the best handling, firing and bonding properties,
only this liquid should be used.
New Generation Ceramics
Used to lend an individual accent
to specific incisal enamel features.
Flu Dentine
(Fluorescent Dentine)
This material also belongs to the group
of dentine modifiers. Flu Dentine can
be used to control the brightness of
the veneer. The more Flu Dentine is
added, the brighter the veneer
becomes.
Glaze
This material determines the
surface finish of the ceramic veneer.
Glaze is applied thinly and evenly.
When Glaze is used, the firing temperature can be reduced by about 10 °C.
Because REFLEX® provides a homogeneous surface finish, glaze firing is not
absolutely necessary.

Instructions for use –
Preparing the substructure
Indication
REFLEX® is suitable for veneering all
precious metal alloys with a CTE of
13.8 to 15.1·10-6K-1 (25 – 500 °C).
We recommend the use of WIELAND
high-gold alloys, e.g.
Porta Geo Ti
(biocompatible ceramic alloy)
BioPorta G
(biocompatible ceramic alloy)
Porta P 6
(high-gold ceramic alloy)
and
AGC® electroforming gold and all
low-gold alloys and palladium
alloys.
Substructure ready for the 1st opaque bake
Use of non-precious
metal alloys
Please note that non-precious metal
alloys tend to require more careful
handling. Please refer to our list of
recommendations when choosing
non-precious metal alloys or ask our
sales representative for advice.
Preparing the
substructure
Prepare the substructure according
to the manufacturer’s recommendations.
When using WIELAND alloys please
also observe the recommendations
given in the relevant instructions for
use.
Please note:
Lead-free biocompatible alloys containing zinc (Zn) should be sandblasted and oxidised and then after the
oxide firing they should be pickled
in a clean, hot bath of Wilacid (or
similar) for approx. 5 minutes.

Powder Opaque
1st Opaque bake
For handling reasons, REFLEX®
powder opaque must not be mixed
with distilled water.
REFLEX® powder opaque liquid
ensures that the material stays in
place during application.
After the substructure has been suitably prepared, the first layer of
opaque can be applied.
The opaque is supplied as a paste or
a powder. To apply the opaque, use
the paste brush provided or a suitable powder opaque applicator. The
shape and flexibility of the brush
are designed to suit the viscosity of
paste opaque.
Apply a thin layer of opaque evenly
(semi-coating) to the coping or
bridge framework. Please ensure
that this first layer is not too thick.
If the paste opaque is applied too
thickly, uncontrollable amounts of
liquid can evaporate during preheating and cause bubbles to form.
Crowns after the 1st opaque bake:
The opaque has a smooth and shiny appearance.
Then the first opaque bake is carried out. For firing temperatures
and times please refer to the firing
programmes given at the end of
these instructions.
2nd Opaque bake
The second step is to apply opaque
once more. Here too, it is important
for the reasons given above that the
opaque is not applied too thickly.
Even so, the opaque must completely cover the substructure so as to
ensure that the crown is uniform in
colour.
Please note
The opaque should be applied evenly with an applicator or a brush. The
consistency should be neither too
thick nor too thin. A “wash bake” is
not required.
Avoid excessive riffling and do not
allow thick layers of opaque to coalesce in the occlusal, approximal or
marginal areas. Thick layers of
opaque can crack during firing.

1st Dentine bake
Crowns after the build-up of the dentine layer
Please note
The nanoleucite™ structure of
REFLEX® gives the surface an
extremely high shine after the
1st and 2nd dentine bakes.

16
2nd Dentine bake
After the 1st dentine bake, correct the
shape by grinding with a medium
grain diamond bur. During this stage,
please ensure adequate cooling
(using water drops).
Then fill in any missing areas in the
shape of the crown by an adding a
further layer of dentine or incisal
materials. Use the same method as
described for the 1st dentine bake.
The finished crowns after the stain / glaze bake
Warning
Stains and glazing
Do not mix REFLEX® ceramic materials together with any other types of
ceramic material. REFLEX® has a
unique nanoleuciteTM structure
and is not compatible with other
ceramics.
After the shape has again been
trimmed and corrected, REFLEX®
stains and/or glaze can be used to
give the crown its individual character.
Please note
Please use only REFLEX® stains and
glaze. If other products are used
there is a risk of uncontrolled stress
in the ceramic causing the restoration to fail through tension or pressure cracks. Please mix stains and
glaze only with the stain and glaze
liquid supplied. Apply with a conventional staining brush.
When firing, follow the recommendations shown in the table.
The corrected build-up ready for the 2nd dentine bake
Please note
Avoid applying too much pressure
since this can cause localised overheating. As with all ceramics, excessive grinding causes micro cracks to
occur in the ceramic structure and
can result in failure through flaking,
cracks or fissures.
Please note – glaze
By modifying the firing temperature
and holding time, the degree of
glaze can be varied from matt to a
high shine to suit individual requirements.

Professional build-up –
step by step
REFLEX® Professional by
Christian Ferrari
Nature knows no bounds when it comes to
the interplay of light, form and colour.
Time and time again, nature surprises us
with the perfection and harmony of creation. We are faced with the difficult task
of imitating this vibrant world with our
limited technical means. In order to do
justice to this task I need materials
which do not restrict my creativity but
give me the freedom to imitate nature.
With conventional materials we were able
to influence three properties of the
ceramic layers: chroma, brightness and
transparency.
With REFLEX® I have a further dimension
at my fingertips: depth of colour through
contrast. By using the Chromatix™ dentine materials I can control contrasts and
achieve unique depth of colour which
enables me to imitate the actual play of
light found in natural dentition.
At this stage a variety of different
dentine modifiers and opal materials
can be applied in order to obtain the
desired effects in the mamelon area.
In the incisal area I use Flu Dentin in the
areas on which light is to be reflected (on
the mamelons).
It is important that the light is absorbed
between the mamelons as in natural
teeth. The next step is to define the
external contour of the tooth with Incisal
Aquamarin, if required. Then I apply alternate layers of Incisal and Opale materials
and build up the final shape with Transpa
materials. If necessary, the first firing
can be complemented by a correction
firing with Transpa materials. REFLEX®
enables me to achieve excellent results in
my laboratory, even with the most
demanding of cases.
Professional build-up
In addition to the standard threelayer technique, it is also possible to
produce an advanced, professional
build-up. The following materials
are available for this purpose:
■
Chromatix™
■
Flu Dentine
■
Dentine Modifier
■
Opale Incisal
■
Opale Effect
■
Incisal
■
Incisal Modifier
■
Transpa Neutral
■
Transpa Clear
■
Stain
These modifiers can be mixed
together in any way you like.
The most popular uses of these
materials are shown in the watercolour illustration on page 25.
To achieve this goal I build up the restoration as follows:
After the opaque bakes I apply
Chromatix™ Dentin onto the whole substructure, keeping the final shape in mind
and characterising certain areas of the
dentine core still further by using effect
materials (dentine modifiers and opal
materials). Then I fire the dentine materials, which I reduce a little in order to make
space for the materials that follow.

REFLEX® Chroma Dentine materials
Applications
■
Chromatix™ materials are dentine
modifiers used to control and individualise chroma and opacity.
■
By increasing opacity the metal
framework can be more effectively
concealed whilst simultaneously
intensifying the chroma (depth of
shade), even with relatively thin
layers of ceramic.
■
Chromatix™ can be mixed with normal dentine to modify chroma and
opacity. Alternatively, it may, if the
case requires, be used on its own.
Please note
The Chromatix™ layer (controlling the chroma)
Always use Chromatix™ in conjunction with our X carving liquid. Only
then are you assured of maximum
brightness, translucency and ideal
handling properties.
Firing Temperature
■
For firing programmes please follow the recommendations set out
in the firing tables for the 1st and
2nd dentine bakes on page 40. You
will find the firing temperatures
and times at the end of these
instructions.

The REFLEX® Expert Set
(Professional Set)
REFLEX® Expert Set
Applications
■
The Expert Set offers you even
more scope to individualise the
features of your restorations.
■
In addition to the Bleach and Gum
materials, you have 8 Incisal
Modifiers and 4 Opale Effect
powders to choose from.
■
Incisal Modifiers and Opale Effect
powders are not colour-keyed and
may be used on their own or mixed
with other materials.
■
They are used to individually
enhance internal enamel and
opalescence characteristics.
■
■
■
■
■
■
■
■
■
■
■
Moreover, analogous to the
diminishing translucency, the
fluorescence of these materials
shows a linear increase.
This makes them ideal for simultaneously enhancing and regulating
the brightness of the veneer in the
incisal area.
■
Example 1:
Opale Effect Frosty has the highest
translucency and opalescence and
the lowest fluorescence.
■
Example 2:
Opale Effect Snow has the lowest
translucency and opalescence and
the highest fluorescence.
■
■
Special characteristics of
Opale Effect powders
■
■
■
■
■
■
In contrast to the standard Opale
Incisals, which are colour-keyed,
the Opale Effect materials are
characterised by linearly diminishing translucency and opalescence.

The individual colour shades and
translucency are shown on the enclosed shade guide. Like all REFLEX®
shade guides this has colour samples
in the original ceramic, which
enables you to make an exact colour
identification of the individual
powders in a wide variety of
lighting conditions (incident light
and transmitted light).

REFLEX® Shoulder Materials
Preparation
To obtain metal-free crown edges
the die must be prepared with a
step or pronounced chamfer.
Designing the
substructure
Firing temperature
■
■
The 7 REFLEX Shoulder High (high
fusing) materials are baked at a
firing temperature of 930 °C with a
holding time of 1 minute before
the first dentine bake.
Shoulder High and
Shoulder Correction –
share these features
®
The 7 REFLEX® Shoulder Correction
materials are baked at a firing
temperature of 720 °C with a
holding time of 1 minute after
the glaze bake.
■
Minimal shrinkage during firing
■
High form stability even after
repeated dentine and glaze bakes
■
Excellent marginal fit
■
Perfect colour matching
■
Simple control of translucency,
fluorescence and reflection
■
REFLEX® SH special shoulder liquid
must only be used with Shoulder
High material.
Applications
■
■
■
The Shoulder Correction materials
are not only suitable for the fabrication and correction of ceramic
shoulders after the glaze bake.
Because of their low firing temperature they can also be used for all
other corrections such as making
minor corrections to the shape or
adding contact points. This means
that Shoulder Correction can be
used to make corrections even
after soldering in a furnace.
Shoulder High Flu / Shoulder
Correction Flu materials can be
used to conceal dark areas such as
discoloured tooth enamel or discoloration at the edges of crowns, to
improve brightness and enhance
translucency.
Shoulder High Red / Shoulder
Correction Red materials can be
used to quickly and easily modify
the transition between the prepared stump, the ceramic shoulder
and the gingiva.
In preparation for the attachment
of the ceramic shoulder, (labial or
circular), the outer edges of the substructure are reduced to the inner
rim of the previously prepared step
or chamfer. The metal edge resulting from this reduction must then
be smoothed out into a thin layer.
Finally condition the substructure in
the usual way and apply the opaque.
Do not use diamond burs. Diamond
particles can become deposited in
the alloy and cause bubbles when
the ceramic is fired.
Carving liquids
■
This carving liquid plasticizes
the shoulder porcelain and
ensures the greatest stability and
reliability. This makes it very easy
to lift the porcelain shoulder from
the model.
■
Use REFLEX® SC Shoulder Correction
Liquid with Shoulder Correction
porcelain.
■
SH special shoulder liquid must not
be used with Shoulder Correction
porcelain, as there is no guarantee
that firing will remove the liquid
reliably and without trace.
Well prepared die
IsoPen
■
The WIELAND IsoPen is applied to
the prepared plaster die.

Prepared substructure
Preparing the die
Before creating the ceramic shoulder the
die must be thoroughly insulated using the
“WIELAND IsoPen”.

Second Shoulder High
layer
Insulating the die with

First Shoulder High
layer
Depending on the tooth colour to
be obtained make up Shoulder
High porcelain with SH Special
Liquid and apply in the cervical
region. After modelling and smoothing the ceramic shoulder, dry the
shoulder margin carefully with a
hand-held dryer until a uniform
white colour is obtained. The
coping can then be removed and
fired. Using a drier and SH Special
Shoulder Liquid ensures greater
strength and more reliable handling.
After firing, check the marginal fit.
Correct any changes caused by sintering. Insulate the die once more.
Prepare and make up the Shoulder
High powder as for the first layer.
Next smooth out any unevenness
filling the Shoulder powder into the
gap created during the first firing,
ensuring that the ceramic shoulder
is a good fit. Finish off the shoulder
and dry. Carefully remove the substructure with the shoulder powder
applied from the die and position it
on the firing tray. To avoid “baking
on” care must be taken to ensure
that the ceramic shoulder does not
come into contact with the tray.
Ceramic shoulder inside view
If necessary, the shoulder must be
fitted onto the model again after
the correction firing. The final stage
is to completely veneer the shoulder
with REFLEX®.

Warning
Firing temperatures are given for guidance only. Variations may occur depending on the furnace used and the temperatures may need to be adjusted accordingly. For larger cases the drying and final cooling times should be extended as
necessary.
In the case of large-span bridgework relief cooling (opening the furnace door slowly) may be necessary to avoid thermal
tension. With large-span bridge frameworks the geometry (e.g. with solid pontics) may necessitate increasing the end
temperatures of the first and second dentine bake by approx. 10 °C.

REFLEX® Gum Dentines
Applications
■
■
With their variety of colours (5 differently shaded powders), the
Gum Dentines may be used to
accurately reproduce the exact
colour of the gingiva.
Particularly in the case of ceramic
veneers over an implanted superstructure, it is essential to ensure
anatomically correct results when
repairing abraded soft tissue surfaces. But extractions or periodontal
procedures can also lead to soft
tissue defects after the healing
process is complete.
■
In the interests of both aesthetics
and periodontal hygiene, these
defects must always be repaired by
the dental technician using suitable ceramic materials.
■
With their wide range of colours
and excellent handling properties,
the Gum Dentines facilitate an
anatomically exact and colour-matched reconstruction of the gingiva
to meet the demands of both
patient and dental practitioner.
Procedure and firing
temperature
■
Gum materials can be used on
their own or mixed with one
another. This gives rise to a
virtually unlimited range of
possible gingival colours.
■
For information on preparation
and firing please refer to the
recommendations for dentines in
the instructions starting on page 16.
Veneering with gum dentine
36
REFLEX® Bleach Materials
More and more patients
wish for perfect, bright,
white teeth.
With natural teeth, this is achieved
through so-called “bleaching” (bleaching of the natural tooth enamel).
In order for ceramic veneers to blend
harmoniously, they must also be as
aesthetically perfect as possible.
In the past the build-up procedure
for “bleach ceramics” was: White
Opaque – White Dentine – Bright
Incisal or Transpa.
Accordingly, the tooth colour is
composed of a virtually unaltered
dentine colour and a considerably
brightened surface.
We already took this into consideration when developing our proven
Crystal Bleach Shades.
With this new colour and build-up
concept, the dental technician is
now able to achieve beautifully
aesthetic results, whether in restorations with existing “bleached”
natural dentition or in the fabrication of complete restorations.
However, this build-up technique
has significant drawbacks, especially
when compared to already “bleached” natural dentition, because
the bleaching process starts from
the tooth enamel and proceeds
inwards and although the enamel is
treated, the natural dentine either
remains unaffected by the procedure
or is affected to a much lesser degree.

Description of
ceramic materials
■
The Opaque Modifier White paste,
Opaque A1 paste and Opaque B1
paste may be combined with all
three dentines.
■
The Dentines:
Crystal Dentine Light is the brightest with the lowest chroma and
tends towards the white range.
Crystal Dentine Pearl has a somewhat higher chroma content than
Crystal Dentine Light and is to be
classified in the “reddish, brown”
range (A colours).
Crystal Dentine Crème has the
highest chroma content and is in
the “reddish, yellow” range
(B colours).
■
■
Crystal Flu Dentine
(Bleach Fluorescence Dentine):
Compared with the other dentine
types, this has the highest brightness value and the strongest
fluorescence.
May be mixed into the corresponding Crystal Dentine (Light, Pearl
or Crème) or used as a modifier
to achieve the desired levels of
fluorescence and brightness, for
instance around the cervical margin of a tooth.
Crystal Flue Dentine may be used
individually as a modifier.
Incisals:
These are exclusively Opal Effect
materials.
Opale Effect Frosty, Ice, Milky and
Snow are graded according to
their translucency and opalescence. Frosty is the most translucent
incisal with a very distinct opalescent effect, followed by Ice, Milky
and Snow, with Opale Effect Snow
having the least amount of translucency. Opale Effect Milky and
Snow may be used as standard
incisals without being allocated
to any particular incisal.
■
Opale Effect Frosty and Ice may be
used individually. They have a
distinct opalescent effect and are
for particular use at the incisal
edge and at the side of the tooth.
■
Incisal Modifier:
Crystal Opale Incisal Blue may be
used as a standard incisal or also as
a modifier where indicated. It has
a whitish blue opalescence, similar
to that of young teeth.
Incisal Aquamarin is used as a
modifier for bluish incisal areas.
■
Transpa Materials:
There are two materials available
with varying degrees of translucency.
Transpa Clear, which is very translucent (like glass) and Transpa
Neutral, which is somewhat less
translucent. Transpa Neutral can
also be used to adjust the colour
intensity of the ceramic. It must be
noted that while the translucency
increases according to the amount
of Transpa Neutral mixed in, the
colour intensity (chroma) is reduced at the same time.

■
Shoulder Powder:
A white shoulder powder, Crystal
Shoulder High, is available. If a different colour is required for the
shoulder, the compatible REFLEX®
shoulder powders may be used
Crystal Shoulder Correction
powder is suitable for creating
and correcting ceramic shoulders
after glazing.
