Naturally beautiful and naturally safe: Cementing.

Cergo Kiss all-ceramic restorations cannot be tem-

porarily cemented and then worn in situ.

Cergo Kiss must be adhesively attached.

Adhesion

Cergo Kiss must be adhesively attached. This is recommended

not only because of the stronger bond obtained, but also

because of the better aesthetic result. Make sure to follow the

adhesive manufacturer’s instructions. The list of suitable adhe-

sives includes: Calibra, Dentsply; Nexus, Kerr Dental; Variolink II,

Ivoclar Vivadent; Compolute, 3M Espe; Duo Cement plus,

Coltene Whaledent.

All cementing surfaces of Cergo Kiss restorations must be

etched with 5% hydrofluoric acid for four minutes. Using 10%

hydrofluoric acid reduces the etching times to two minutes.

Suitable products include: Vita Ceramics Etch (Vita Zahnfabrik),

Porcelain Gel Etch (Ultradent).

All surfaces treated with hydrofluoric acid must be silanized.

All popular silanizing agents are suitable, such as: Calibra Silane

Coupling Agent, Dentsply; Monobond-S, Ivoclar Vivadent; Silane,

Ultradent; Silan Primer, Kerr Dental; RelyX Keramik Primer,

3M Espe

Please note that a silent rising layer shows pronounced aging

after as little as 30 minutes. This is why silanization should wait

until shortly before insertion.

In order not to compromise the quality of the

definitive cementing, temporaries should only be

cemented using non-eugenol cements.

These Instructions for Use are logically continued by the

Instructions for Adhesive Cementing, which is available from

DeguDent free of charge.

Give your best:Cergo Kiss – the best for patients and the dental team

What characterizes a perfect restoration from the

dental team’s point of view? Its natural look and

its excellent biocompatibility? Or maybe

its longevity? Why not combine all these advanta-

ges in a single ceramic system: Cergo Kiss pressa-

ble ceramics and Duceragold Kiss veneering cera-

mics.

Cergo Kiss and Duceragold Kiss give patients, dentists and

dental laboratories results that are very, very close to the

natural tooth: In addition, both dentists and patients benefit

from the fact that Cergo Kiss is particularly resistant to

fracture.

For restorations where a natural look is particularly important –

such as veneers and anterior crowns – Cergo Kiss can be

adapted perfectly to the neighboring teeth. Cergo Kiss is also

an excellent optical and functional complement for restorations

with a ceramic-veneered gold framework. Use Cergo Kiss

as an integral component of the GoldenGate System. The

GoldenGate System follows a philosophy of simplicity, while

at the same time it places great weight on maximum bio-

compatibility.

8 Introduction

Maximum aesthetics combined with a broad range

of indications and possible applications

Cergo Kiss is the No. 1 pressable ceramic system for highly

aesthetic and biocompatible restorations such as veneers,

inlays, onlays, and crowns within the GoldenGate System.

Together they successfully emulate natural teeth, both in

appearance and material properties: Cergo Kiss unites the

advantages of a hydrothermal ceramic material, such as

smoothness and a surface hardness very close to that of

the natural teeth, with an abrasion behavior similar to that

of dental enamel.

We are not aware of any risks or adverse effects related to

Cergo Kiss pressable ceramics and Duceragold Kiss veneering

ceramics.

Cergo Kiss is used for ceramic restorations using the build-up

and the staining techniques. What exactly does this mean?

Build-up technique

Modeling and pressing frameworks to be veneered with

Duceragold Kiss.

Staining technique

Modeling and pressing fully anatomic frameworks whose

definitive shade is created by staining with LFC (Low Fusing

Ceramic) stains, incisal stains, body stains, and glazing.

Particularly well-suited for the following indications:

• Veneers

• Inlays (one or more surfaces)

• Onlays

• Crowns (anterior and posterior)

Contraindications

The use of Cergo Kiss is contraindicated for

• Bridges

• Very deep subgingival preparations

• Patients with parafunctions (such as bruxism)

• Patients with very pronounced edentulism

Introduction 9

Cergo Kiss shade guide

Cergo Kiss is available in four levels of transparency to simplify

the choice of material depending on the indication. In addition

to the well-known Cergo pellets, the Cergo Kiss range has

been expanded with two new Opal pellets, Crystal Opal and

Lucent Opal. Its opalescent characteristics, closely resembling

nature, make these materials ideally suited for the fabrication

of anterior inlays and veneers.

Inlays and veneers, enamel area

Inlays and veneers in the enamel area are pressed with opales-

cent pellets (CO, LO) or any Lucent pellets.

Crown copings

Any dentine pellets can be used for fabricating crown copings.

Smaller veneers and inlays

The C and CO materials are preferred for smaller veneers and

inlays thanks to their high transparency.

Pellets of greater opacity (Incisal 1– 4) are preferred for

larger restorations of deeper cavities or where cusps are

included. The increased opacity helps avoid graying effects in

the incisal region.

Pellets for the staining technique

Use P1 and P2 staining (paint) pellets (see tables). For greatly

discolored groups of teeth, the PF pellet can be used.

Shade assignmenttablesBody stains

The values listed here are intended for orientation only and should

be regarded only as guidelines. Your firing results may differ. All firing

results depend on the performance of the furnace used, which in

turn depends on the make, model and age of the furnace. Therefore,

the guideline values will have to be adapted individually for each

firing. We recommend running a test firing cycle to evaluate the per-

formance of the furnace used. We have compiled and checked all

values and other data with great care. However, we cannot be liable

for your results under any circumstances.

Laboratory procedures 11

1. Die preparation

The master casts are prepared as for the fabrication of inlays

and crowns made of precious dental alloys.

Procedure

• Establish the preparation margin.

• Use die hardener on the die.

• Apply Cergo die spacer siena on the dye.

The Cergo die spacer (one layer of approximately 15 µm in

thickness) or the colored die spacer (two layers of approxi-

mately 15 µm in thickness) is used as a placeholder for the

cementing gap. In the case of crowns, a special spacer fluid is

applied to within 1 mm of the preparation margin on the die.

For inlays, the die spacer is applied over the entire prepared

surface to just short of the preparation margin.

Colored die spacer

The colored die spacer was designed to simplify individual

characterization when fabricating e.g. veneers or inlays.

Applying the colored die spacer to the working die optimizes

the shade of the final restoration.

2. Wax modeling

Use only wax materials that burn out without residue.

Use Isolit isolating liquid.

For anterior teeth, the wall thickness of the wax model must

be at least 0.7 mm.

According to Professor Kappert of Freiburg, Germany, the

thickness of the framework should be more than 50% of the

thickness of the veneer in the case of pressable ceramics.

For posterior teeth, wax up a reduced anatomical form

(including the occlusal profile), a type of dentinal core, in

order to ensure sufficient stability.

The longevity of the design is partially influenced by the

thickness of its framework.

Please note:

• To ensure the stability of the structure, allow adequate space for the Cergo restoration.

• To avoid tension, eliminate sharp line angles.

• Avoid preparation undercuts.

• The dentist should fill deep cavities by placing a core restoration.

• Pay particular attention to the design of the margin.

• Allow for a uniform wall thickness wherever possible.

• When preparing anterior or posterior teeth, maintain a framework to veneering material ratio of 50 : 50.

• For inlays, onlays and veneers, maintain a framework to veneering material ratio of 75 : 25 when using

the build-up technique.

4


3. Sprueing

The wax models are sprued with wax sprues (5 – 6 mm long

for the Cergo press ceramic furnace, 2 – 3 mm for the

Multimat Touch&Press). For smaller inlays and copings, the

recommended sprue diameter is 3.0 mm, while it is 3.5 mm

for more voluminous restorations.

Before investing, the number of pellets required is determined

by weighing the wax:

Depending on the size of the objects, a minimum distance of

5 mm is required if more than one object is pressed.

Procedure

• Wax up the pressing sprue in the position of maximum

circumference (incisal for copings, proximal for inlays). Make

sure the diameter of the sprue is not reduced at the contact

point; ensure a large connection area. The pressed object

and the pressing sprue should ideally be arranged in one

line (same direction of flow).

• Position all pressing objects at the edge of the base at the

same height, i.e. with all object margins at the same level.

This will automatically result in sprues of different length.

That is fully acceptable.

Up to4.8 gwaxweight: 8 pressingpellets CerconPressMaster(400-g)


4. Investing technique

The muffle former, the spacer ring and the muffle form holder

should be prepared with an oil-free silicone spray or a thin

layer of petroleum jelly. This preparation facilitates the separa-

tion of the plastic base from the investment compound.

These components should also be free of any residual invest-

ment compound or other contamination; the same is true of

the mixing bowl and a stirring motor.

Procedure

• Place the muffle ring on the muffle former.

• Mix the investment material (Cergo fit or Cergo fit SPEED)

as per the manufacturer’s instruction. Vibrate lightly into

the muffle, avoiding bubble formation, until all objects are

completely covered with investment. Top off the muffle with-

out vibrating.

• Place the spacer ring to ensure correct muffle height

and to provide for a 90-degree position of the muffle base

relative to the pressing direction of the pressing oven.

When placing the spacer ring, investment compound must

exit from the gauge opening.

• Let muffle rest until the investment (Cergo fit or Cergo fit

SPEED) has set. Protect from vibration.

5. Pre-heating

Ensure that the pre-heating often is clean to avoid contami-

nation of the muffle and depressing die.

Procedure

• When the investment has set, remove the various parts of

the muffle.

• The spacer ring contact point is cleaned and checked for

90-degree orientation. The muffle must not “rock”, as this

may result in pressing errors.

• The muffle is placed in the pre-heating oven together with

the alumina pressing die, which must be free of ceramic

residue. The base temperature of the pre-heating oven

will depend on your choice of investment material (refer to

pertinent Instructions for Use).

• The single-use pressing dies made from investment com-

pound are not pre-heated.

• Heat the muffle from room temperature to 850 °C (refer to

investment manufacturer’s recommendations for the proper

heating procedure).

• When using Cergo fit SPEED investment, you may place

the muffle directly into the oven pre-heated to 850 ºC after

a setting period of 15 minutes.

Cergo Kiss pellets are not pre-heated.

9


6. Pressing

Avoid long transport distances and waiting times between

removing the muffle from the pre-heating oven and the start

of the pressing process.

Procedure

• Activate the pressing program.

• Remove the muffle from the pre-heating oven once the

starting temperature of 700 °C has been reached.

• Place Cergo Kiss pellets in the muffle channel.

• Position the pressing die.

• Immediately place the muffle this prepared in the pressing

oven and start the pressing program (for Cergo press:

press the start button one more time).

• Once the pressing process has been completed (after

approximately 45 minutes), remove the muffle from the

pressing oven immediately and allow to slowly cool to

room temperature.

Touch&Press pressing program

Cergo Pressprogramm


7. Divesting

Procedure

• Indicate the position of the pressed objects using the pres-

sing die.

• Make a deep cut into the investment compound, preferably

using a diamond-covered and sintered large carbide disc or

(less costly) a carbide disc for metal castings.

• Separate the part of the muffle containing the alumina pres-

sing die from the rest of the muffle using a plaster knife or,

preferably, by turning in opposite directions.

• Use a jet polisher (50 µm, 4 bar; do not use a revolving-jet

unit) to remove the investment all the way to the pressed

objects. In doing so, make sure not to touch the objects

(abrade the “internal cylinder” and remove the external ring

of investment).

• Once the objects have become visible, continue abrading

across the area using reduced pressure (2 bar).

• Clean the alumina pressing die using alumina abrasive and

rinse.

Do not use alumina for air-abrading. Do not concentrate the air-abrading force on small areas.

8. Finishing

The pressable ceramic object should be water-coo-

led during finishing. Keep the pressure on the fra-

mework material to an absolute minimum in order

to avoid overheating the pressable ceramics and

the formation of cracks. Use only new or almost

new rotary instruments, as the temptation is other-

wise high to compensate the re-duced cutting effi-

ciency of used instruments by applying more pres-

sure.

Note the minimal thickness requirements for inlays (2 mm

where the inlays narrowest) and crown copings (0.7mm).

Procedure

• Cut off the sprues using water cooling and no pressure.

• The restoration to be veneered or painted is then finished

using diamond burs or stones.

• Use a steam cleaner (Aquaclean) to clean the object. Do not

approach the object too closely with the nozzle (risk of local

overheating).

14 15


9. Staining technique

The staining technique uses the LFC stains. These are mixed

to a firm, homogeneous consistency (like a very soft wax)

and worked into the surface with a brush until the surface is

saturated. Irregularities should be avoided.

Fire the stains until the desired characteristic is achieved. To

do so, make the glaze to a very firm consistency and work

into the surface using a taste opaque brush.

You may also use fluorescent body and incisal stains for the

staining technique. These stains allow a broad and regular

characterization of the ceramic surface.

Application of body and incisal stains

• Detailed characterization of the ceramic surface as a paint

firing (build-up technique)

• Complete color characterization after pressing with the P1

and P2 pellets

• Reproduction of all “V” colors

• Gross or detailed characterization of all pressed pellets

(painting and layering technique)

• Use for all CTE-adjusted ceramics.

• In principle, all pellets can be used with body and incisal

paints.

Depending on the consistency of the mixed body stains,

the number of stain firings has to be increased or reduced

by one.

Restoration, prepared for the staining technique The same restoration after glaze firing

16 17

Body and incisal stains are applied depending

on the circumstances of the individual case. The

table on page 10 gives you a first orientation

regarding the use of body stains.


10. Build-up technique

For veneers, inlays and crowns, use the layering technique

and Duceragold Kiss. Dispense with the opaque firing and

start building up the ceramics by analogy with ceramo-metal

restorations.

When fabricating inlays, take care that the veneering masses

are separated in the middle, all the way down to the bottom,

in order to ensure control shrinkage.

Pressed coping Second dentine firing Finished restoration

For larger restorations, the final temperature should

be increased from 800 °C to 810 °C.

Firing a ceramic shoulder onto the Cergo Kiss fra-

mework is discouraged for reasons of stability.

General firing instructions

Veneers and inlays are fired on a single-ply piece of firing

cotton, which should be as small as possible and is placed

on top of the firing pins. Crowns are fired on the special firing

pins provided for this purpose.

The glaze firing is performed at 800 °C using LFC glaze and

body stains.

The firing temperature must be increased for all firing

steps in order to balance the low thermal conductivity of

the pressable ceramic framework. As a rule, the firing tem-

perature (final temperature, 80 °C) is approximately 20° C

to 30 °C higher than if Duceragold Kiss is fired to high

gold alloys.

Remove the object from the furnace immediately after the

firing program has run. Use no long-term cooling or tem-

pering phases.

For your orientation: The luster of the veneer after the first firing should be comparable with the veneer of precious-metal frameworks of the

GoldenGate System.

The values listed here are intended for orientation only and should be regarded only as guidelines. Your firing results may differ. All firing results de-

pend on the performance of the furnace used, which in turn depends on the make, model and age of the furnace. Therefore, the guideline values

will have to be adapted individually for each firing. We recommend running a test firing cycle to evaluate the performance of the furnace used. We

have compiled and checked all values and other data with great care. However, we cannot be liable for your results under any circumstances.

Troubleshooting

Problem

• Muffle is damaged after firing

• Flash and voids at the margins and on the inside ofcrowns

• Flash on restorations and sprues

• Restorations are not completely pressed

Cause

• The muffle and the pressing die were not perpendi-cular to the pressing direction, tilting the pressingdie and breaking the muffle

• Pressure too high

• Incorrect sprueing

• Cracks in the investment compound (microcrack)

• Number of pressing pellets is insufficient for thenumber and size of objects too be pressed

• Pressing temperature to low• Actual temperature inside the pressing oven doesnot reach the pre-selected temperature

• Pressing time too short• Pressure too low

Solution

• Always use the spacer ring to ensure the correctperpendicular position of the muffle

• The pressing sprue and the wax model must be inalignment

• Follow the pre-heating recommendations for theinvestment compound

• Observe the second time of the investment compound• Do not place the muffle in a hot pre-heating oven(does not apply to Cergo fit SPEED)

• Determine the weight of the wax model and thesprues to calculate the number of pellets needed

• Set the pressing temperature to 980 °C• Check and, if necessarily, recalibrate thepressing oven

• Set the pressing time to 20 minutes• Set the pressure to 4.5 bar

Service 27

Problem

• Cracks when cutting off the sprues• Cracks when trimming the restauration

• Crown is too narrow (bad fit)• Crown is too wide (bad fit)

• MOD inlay is too wide• MOD inlay is too narrow

• Porosities or white stains on the surface of therestoration or discoloration

• Cracks occur after firing

• Restoration does not fit after firing

Cause

• Local overheating of the pressable ceramic materialdue to the use of improper grinding instruments orexcessive pressure

• Concentration of the mixing fluid is too low• Concentration of the mixing fluid is too high

• Concentration of the mixing fluid is too high• Concentration of the mixing fluid is too low

• Modeling wax that has not burned on completely• Pressing temperature too high

• Incorrect firing parameters• Carrier was left on the firing plate after firing• Incorrect firing pin was used or object was fireddirectly on the carrier

• Restoration has been distorted by excessive firingtemperature

• Ceramic material is present on the inside of the restoration• Restoration does not have the required minimumwall thickness

Solution

• Use sharp and fine diamond burs at low pressure• Cool the restoration with water while grinding

• Use mixing fluid of the proper concentration

• Use mixing fluid of the proper concentration

• Use wax specially designed for all-ceramic restorations• Set the pressing temperature to 980 °C

• Fire without any cooling step• Remove the carrier from the oven immediately after firing• Fire crowns on special firing pins• Fire inlays on a small piece of firing cotton placed onfiring pins

• Decrease the firing temperature• Check the internal surfaces and remove any ceramicmaterial

• Observe the minimum wall thickness requirements
