Material

Telio Lab

Telio Lab is a PMMA-based two-component
powder/liquid system for the cold poylmerization
in A-D shades. It is used for the fabrication of
temporary crowns and bridges.

Telio Lab exhibits excellent polishing properties and
thus a resulting smooth surface.
Stains and/or layering materials can be used to
apply final esthetic optimizations.
Relinings, add-ons, emergence profiles and
occlusal build-ups can be carried out with Telio Lab
(laboratory), Telio CS C&B (dental practice) or Telio
Add-On / Flow in both areas.

Telio Lab can be used in conjunction with different
processing techniques:

• Casting technique

• Injection technique

• Casting of temporary veneers for pre-ground

artificial teeth

Product information

Telio CAD

Telio CAD are cross-linked PMMA blocks for the
fabrication of long-term temporaries by means of
the CAD/CAM technique. As a result of the indus­trial polymerization process, the blocks feature a
high material homogeneity. There is neither poly­merization shrinkage nor an inhibited layer. Given
the CAD/CAM fabrication, the temporary can be
easily reproduced at all times. Stains and/or
layering materials can be used to apply final
esthetic optimizations.

Shade determination

Shade determination of the natural tooth

After tooth cleaning, the tooth shade of the non-prepared tooth
and/or the adjacent teeth is determined with the help of a shade
guide. Individual characteristics have to be considered when
deter-mining the tooth shade. If a crown preparation is planned, for
example, the cervical shade should also be determined.
In order to achieve the best possible true-to-nature results,
shade determination should be carried out at daylight.
Furthermore, the patient should not wear clothes of intensive
colours and/or lipstick.

Fabricating the model

Fabricate a master model or a model with detachable segments
according to the impression in the usual manner. Generally, a sealant
for surface hardening should be applied once the preparation mar­gins are exposed.

The directions of the manufacturers of the different CAD/CAM
systems regarding the plaster to be used must also be observed for
the use of Telio CAD blocks.

Important for die preparation:

• Check the radius of the incisal/occlusal edge on the prepared dies

(maxilla and mandible).

• The prepared incisal edge should be at least as thick as the dia-

meter of the bur used in the cavity during the CAD/CAM process.
If the incisal edge of the prepared die is more pointed and thinner
than the diameter of the bur, the incisal edge has to be blocked
out accordingly.

• Also observe the information provided by the manufacturer of the

CAD/CAM system regarding the die geometry.

Minimum material thicknesses / layer thicknesses

The design of the restoration is the key to a successful temporary
restoration that also paves the way for the incorporation of the per­manent restoration. The more attention is given to the design, the
better the final results and the clinical success will turn out to be.

The following basic guidelines have to be observed:

• In large preparations and for veneered or partially veneered

restorations, the excess available space must be compensated by
the corresponding dimensions of the stable Telio Lab and/or Telio
CAD component and not by the layering material.

• The transition to the layering material must not be located in the

area of the functional contact points.

• With Telio CAD the design of the restoration generated by the

software has to be individually adjusted in accordance with the
clinical situation using the design tools. The build-up of missing
areas that support and reinforce the shape and cusps of the resto­ration are constructed with the integrated design tools of the dif­ferent types of software used.

Minimum material thicknesses / layer thicknesses

The restoration design is key to the success of a temporary restoration. The more attention given to the
design, the better the final results and the clinical success will turn out to be.

The following basic guidelines have to be observed:
– Support the restoration with a framework (metal, Vectris) in long-span bridges or if space is limited.
– The minimum wall thickness of 1.5 mm occlusal and 0.8 mm circular must be observed at all times.
– The connector dimensions for anterior bridges with up to two pontics must be at least 12 mm
– The connector dimensions for posterior bridges with one pontic must be at least 12 mm2and with up

to two pontics at least 16 mm

Preparing and isolating the model

– Remove the silicone key from the model once it is set and clean off any wax residue from the model.
– Block out undercuts and cuts between model segments.
– Immerse the model in water for 5 minutes. Then, apply two layers of Separating Fluid. Wait between

the two layers until the surface is no longer shiny.

Important

A higher room temperature shortens the processing time. The mixing ratio between the
polymer and the monomer also influences the processing time. If the mixing ratio is correctly
observed, a relatively flowable consistency is achieved.

– Pour the desired amount of Telio Lab Cold Liquid into a clear mixing beaker.
– Dispense the same amount of powder into a second mixing beaker.
– Subsequently, add the powder to the Cold Liquid and mix without creating air bubbles using a model-

ling spatula.
– Cover the beaker and allow a dough time of approximately 2 minutes.
– Pour the now well-flowable Telio Lab resin evenly into the silicone key.
– Once the resin has reached its plastic phase, it can be contoured using an instrument that has been

wetted with monomer.

Fabricating temporaries in the casting technique

– Fill the silicone key with ready-mixed and well-flowable Telio Lab Dentin without causing any air bubbles.
– Apply Telio Lab Dentin on the isolated model without air bubbles.
– Place the silicone key on the model in the correct position.
– Once Telio Lab has reached its plastic phase, the material is polymerized under pressure in a water

bath for 15 minutes at 2-6 bar / 29-87 psi and a temperature of 40-50 °C / 104-122 °F.

Individualizing the incisal area using the cut-back technique

– After polymerization is completed and the restoration has been removed from the silicone key, the

incisal area of the Telio Lab restoration is reduced by means of cross-cut burs.
– Check the reduction (cut-back) with the silicone key.
– Blast the surface with aluminium oxide at 2 bar / 29 psi pressure or roughen.
– Apply Telio Lab Cold Liquid (monomer) on the clean surface (reaction time min. 2 to max. 4 minutes).
– After that, condition the surface with SR Composiv in order to ensure a sound bond between the

restoration and Telio Stains. The layer thickness of SR Composiv must be between 0.2 and 0.5 mm;

the processing time is 3 minutes.
– The material is cured in a light-polymerization device (e.g. Spectramat).
– The incisal area is now individualized using Telio Stains.

15

The respective light-curing Telio components are pre-polymerized to ensure that they stay in place and to
be able to apply a further layer. However, final polymerization of the entire restoration is always required.

Finishing and polishing

Finishing

Use (fine) cross-cut tungsten carbide burs to finish
Telio Lab restorations.
– Use cross-cut tungsten carbide burs for shape

adjustments.
– Overheating of the material must be avoided.
– The restorations are tried in on the dies and care-

fully finished.
– Check proximal and occlusal contact points.
– Make sure that the minimum thicknesses are

maintained even after the minor adjustments.

Removal of excess material

Polishing

Careful polishing is the prerequisite for an optimum esthetic result. Polishing reduces plaque acummula­tion and the resulting shade disturbances.
– Pay special attention to crown margins, interdental areas, occlusal surfaces and the basal rest area of

pontics.
– Manual polishing of the restoration is carried out with rotary instruments and polishing paste.

Pre-polishing

– Smooth out the surface (convex areas) of the natural structures as well as the marginal ridges with

rubber polishers and silicone polishing wheels so that they exhibit an extra lustre after high-gloss

polishing.
– Pre-polishing is done with the handpiece / goat hair brushes and fine pumice / Universal Polishing

Paste.

High-gloss polishing

– Polish the restoration to a high gloss using goat hair brushes, cotton or leather buffing wheels as well

as the Universal Polishing Paste.
– Use low speed and limited pressure for high-gloss polishing. Adjust the pressure with the handpiece,

not the polishing motor.
– In order to optimally polish the interdental areas and occlusal surfaces, we recommend modifying the

goat hair brushes to become star-shaped so that only the desired areas can be polished due to the

smaller size of the brush.
– Depending on the type of high gloss desired, leather buffing wheels can be used to achieve a high

shine, while cotton buffs are used to achieve a lower degree of lustre.

Fabricating temporaries in the
injection technique (syringe)

This technique is particularly recommended for long-span restorations. The resin can be quickly and evenly
applied into the doubling mould or the silicone with a customary syringe (available in pharmacies).

Wax-up and silicone doubling

Provide at least two sprues on the wax-up for long-span restorations (e.g. wax wire or 3-4 mm plexiglass
pin).

Important

Thoroughly block out all areas between the wax-up and the model so that no doubling
silicone may enter the area between the wax-up and the model. Block out cuts between
model segments with wax.

– Double the model with the wax-up by means of a doubling mould. It is important that the entire wax-

up is embedded in silicone.
– The wax-up is embedded in silicone. Remove the wax wires or plexiglass pin after setting.
– Transparent silicone is particularly useful since it enables better optical control during injection.

Model preparation and isolation

– Once the silicone has set, remove the model with the wax-up and clean off wax residue.
– Block out undercuts and cuts between model segments with wax.

Information

Rough surfaces or undercuts may be isolated or blocked out using the elastic isolating gel SR Ivocron
Separator. Apply SR Ivocron Separator and allow to dry for approximately 5 minutes.

– Immerse the model in water for 5 minutes. Then, apply two layers of Separating Fluid. Wait between

the two layers until the surface is no longer shiny.

18

First injection (Dentin)

– The model is now replaced in the doubling mould.
– Pour the desired amount of Telio Lab Cold Liquid into a clean mixing beaker.
– Dispense the same amount of powder into a second mixing beaker.
– Subsequently, add the powder to the Cold Liquid and mix without creating air bubbles using a

modelling spatula.
– Inject the now well-flowable Telio Lab resin evenly into one of the sprues using a customary syringe

(pharmacy).

Finishing and polishing

Finishing

Use (fine) cross-cut tungsten carbide burs to finish
Telio Lab restorations.
– Use cross-cut tungsten carbide burs for shape

adjustments.
– Overheating of the material must be avoided.
– The restorations are tried in on the dies and care-

fully finished.
– Check proximal and occlusal contact points.
– Make sure that the minimum thicknesses are

maintained even after the minor adjustments.

Removal of excess material

Polishing

Careful polishing is the prerequisite for an optimum esthetic result. Polishing reduces plaque acummula­tion and the resulting shade disturbances.
– Pay special attention to crown margins, interdental areas, occlusal surfaces and the basal rest area of

pontics.
– Manual polishing of the restoration is carried out with rotary instruments and polishing paste.

Pre-polishing

– Smooth out the surface (convex areas) of the natural structures as well as the marginal ridges with

rubber polishers and silicone polishing wheels so that they exhibit an extra lustre after high-gloss

polishing.
– Pre-polishing is done with the handpiece / goat hair brushes and fine pumice / Universal Polishing

Paste.

High-gloss polishing

– Polish the restoration to a high gloss using goat hair brushes, cotton or leather buffing wheels as well

as the Universal Polishing Paste.
– Use low speed and limited pressure for high-gloss polishing. Adjust the pressure with the handpiece,

not the polishing motor.
– In order to optimally polish the interdental areas and occlusal surfaces, we recommend modifying the

goat hair brushes to become star-shaped so that only the desired areas can be polished due to the

smaller size of the brush.
– Depending on the type of high gloss desired, leather buffing wheels can be used to achieve a high

shine, while cotton buffs are used to achieve a lower degree of lustre.

Completed temporary restoration

Metal-supported temporary

With long-span bridges and limited space, it is required to reinforce the temporary restoration with a
framework made of a dental alloy.

Fabricating the model

– Fabricate a master model or a model with detachable segments according to the impression in the

usual manner.
– Once the model with detachable segments has been prepared, the preparation is exposed.
– For better control, the preparation margin is marked and sealed.
– A spacer is applied on the preparation as a spaceholder for the temporary luting cement (Telio CS

Link).

Framework design

The framework design is the key to a succeful metal-supported temporary restoration. The following basic
guidelines have to be observed:
– The wax-up framework reflects the reduced anatomical tooth shape (contouring supporting the tooth

shape).
– The minimum wall thickness of 0.3–0.5 mm, depending on the alloy and the instructions of the

manufacturer, must be observed at all times.
– Sufficient connector dimensions of the metal framework must also be observed.
– Use the silicone key to check the contouring.

Application of retention beads

In addition to the chemical bond with SR Link, a mechanical bond by means of rentention beads must be
provided. The rentention beads are applied following functional and esthetic aspects. Once the sprues
have been placed, apply the retention adhesive in a thin layer and allow a reaction time of approximately
20 seconds so that the solvent may evaporate and the retention beads do not sink into to it and provide
sufficient surface for the mechanical retention.

Important

Mechanical retentions ensure the mechanical bond between the metal and the veneering
resin and must be applied.

Sprueing and investing (do not use a debubblizer). Process the alloy according to the instructions of the
manufacturer.

Surface finishing

– Carefully divest the cast framework and blast with Al2O3according to the instructions of the alloy

manufacturer.
– Separate the sprues and finish the framework using cross-cut tungsten carbide burs.
– For esthetic reasons, the retention beads may be reduced by half (equator) so that sufficient retentive

surface is still available.
– For an improved bond with the Telio Lab Opaquer, the metal surface is blasted with Al

2–4 bar/29–58 psi (observe the instructions of the alloy manufacturer).

Telio CAD

CAD/CAM processing

The fabrication steps are described in the directions for use and user manuals of the different CAD/CAM
systems. The instructions of the manufacturers must be followed.
Observe the stipulated minimum thicknesses and connector dimensions.

Important for the processing in Sirona milling devices

In comparison with ceramic materials, a reduced quantity of Dentatec fluid per tank filling is
required. Please refer also to the Ivoclar Vivadent abrasives overview.
The CAD-Waxx Starter Kit from Sirona with a modified tank and reinforced filter system
(from specialized dental dealers) is required for the processing in MC-L devices.

Prevention of premature loss of retention:

Apart from a retentive preparation design, the reliable cementation of Telio CAD restorations using a
temporary luting material (e.g. Telio CS Link) depends on the accuracy of fit, which is determined by
the CAD/CAM system used.

Telio CAD – CAD/CAM processing

29

Fully anatomical fabrication and
final polishing

In this processing technique, the restoration is
polished and incorporated immediately after milling
in the CAD/CAM system. In the process, the surface
lustre is achieved by manual polishing. This pro­cessing technique is very efficient and leads to an
esthetic result quickly and easily.

After milling in the CAD/CAM device, the resoration
is separated from its holder with a fine tungsten car­bide bur or a diamond separating disk and fitted on
the model.

Note

Remove any possible white spots on the restoration that have developed during milling in the
CAD/CAM device using a tungsten carbide bur.

Finishing

Use (fine) cross-cut tungsten carbide burs to finish
Telio CAD blocks.

Observe the following procedure for finishing Telio CAD restorations:
– Use cross-cut tungsten carbide burs to smooth out the attachment point.
– Use cross-cut tungsten carbide burs for shape adjustments.
– Overheating of the material must be avoided.
– The restorations are tried in on the dies and carefully finished.
– Check proximal and occlusal contact points.
– Surface-grind the entire occlusal surface with a fine diamond to smooth out the surface structure

created by the CAD/CAM procedure.
– Make sure that the minimum thicknesses are maintained even after the minor adjustments.
– Make sure to thoroughly clean the restoration before further processing and to remove any residue of

the milling additive of the CAD/CAM milling unit. Residue of the milling additive remaining on the sur-

face may result in bonding problems.
– Try in the restoration, if necessary.

Telio Lab / Telio CAD

Cut-back technique with Telio Lab LC (light-curing)

The light-curing Telio Lab LC materials are layered onto the incisal and occlusal area of the reduced milled
Telio Lab and/or Telio CAD restorations. The limited application of layering material permits achieving
highly esthetic restorations in an efficient manner.

The cut-back technique is not recommended for:

• Build-up of incisal edges in anterior teeth exposed to high protrusion stress

• Build-up of stress-bearing cusps in posterior teeth

Characterization with light-curing Telio Lab LC materials

Telio Lab LC materials include light-curing veneering
materials in paste form as well as characterization
stains.

The targeted grinding of the transition areas to the
cut-back regions is the prerequisite for the smooth
transition between Telio Lab / Telio CAD and the
light-curing Telio Lab LC material.

Telio Lab/Telio CAD – Cut-back technique with Telio Lab LC (light-curing)

– Always pay attention to the contact points and margins during polishing!
– As an alternative, the ground surface can be blasted with Al
– Thoroughly clean with the steam jet and dry with oil-free air
– Apply preferably a cold-curing MMA-based monomer (e.g.Telio Lab Cold Liquid, Telio Activator); the

reaction time/dough time is min. 2 to max. 4 minutes.
– After that, condition the surface with SR Composiv in order to ensure a sound bond between the

restoration and the layering materials. The layer thickness of SR Composiv must be between 0.2 and

0.5 mm. The material is cured in a light-polymerization device (see SR Composiv Instructions for Use).

Telio Lab materials

Telio Lab is a two-component powder/liquid system
for the cold poylmerization.

The targeted grinding and/or the reduction of the
transition areas is the prerequisite for the smooth
transition between Telio CAD and the cold-curing
Telio Lab material.

– Additionally/alternatively, the ground surface can be blasted with Al2O3at 1-2 bar /15-29 psi pressure.
– Thoroughly clean with the steam jet and dry with oil-free air.
– Apply Telio Lab Cold Liquid on the cleaned surface; the reaction time is min. 2 to max. 4 minutes. The

application of the Telio Lab material is started immediately after the dough time of 4 minutes.

Alternative

Use of a silicone key

If the Telio CAD framework is manually reduced by grinding, a silicone key can be fabricated before­hand. Pour the desired amount of Telio Lab Cold Liquid into a clear mixing beaker after the cut-back
and conditioning. Add the same quantity of Telio Lab Transpa Incisal, mix with a modelling spatula,
cover it and let the material rest for approximately 2 minutes. Pour the now well-flowable Telio Lab
evenly into the silicone key. Then, place the filled silicone key on the Telio CAD restoration.
Once the resin has reached its plastic phase, it can be contoured using an instrument that has been
wetted with monomer. After that, pressure polymerization is conducted (15 minutes at 40-50 °C/
104-122 °F at 2-6 bar/29-58 psi pressure in the pressure pot e.g. Ivomat).

Incorporation

Possibilities for cementation

All Telio restorations are temporarily incorporated. We recommend conventional eugenol-free temporary
cements, such as Telio CS Link.
For long-term temporaries (wear period of more than 4 weeks) regular check-ups are required in order to
recement the restoration, if required.

Prevention of premature loss of retention:

Apart from a retentive preparation design, the reliable cementation of Telio CAD restorations using a
temporary luting material (e.g. Telio CS Link) depends on the accuracy of fit, which is determined by
the CAD/CAM system used.

Frequently Asked Questions

What are the special characteristics of Telio
Lab?

– The shades and material technology of Telio Lab

are coordinated with those of Telio CAD and

Telio CS.
– Telio Lab is exclusively processed in the cold

technique.
– Telio Lab can be processed in the injection

technique (modified flowable phase).

Are the Telio Lab components compatible
with other PMMA resin components?

No.
The individual components of Telio Lab have been
selected in such a way that they result in ideal pro­cessing, shade and material properties. Cross-over
application of other PMMA resins and Telio Lab
components lead to changing processing
properties as well as sub-optimal shade and
material properties.

Can Telio Lab be used as veneering material
for metal-supported long-term temporaries?

Yes. However, the following processing guidelines
have to be observed:
– The metal framework must be given a reduced

anatomical shape and provided with mechani-

cal retentions.
– Blast the metal surface with Al

100 µm, at 2-4 bar/29-58 psi pressure. Then

tap off blasting medium residue on the surface.

Do not use the steam jet or compressed air.
– Start with the application of SR Link immediately.

Apply SR Link with a clean disposable brush

and allow it to react for 3 minutes.
– Mix Telio Lab Opaquer with Telio Lab Opaquer

Liquid to a flowable consistency, cover it, and

let the material rest for approximately

2–3 minutes. Subsequently, cover the entire

framework or model cast components with

opaquer.
– Check setting with an instrument before

continuing with the next working steps.
– In general, the minimum layer thickness of Telio

Lab is 1.5 mm!

means of a brush and let it react for min. 2 to max.
4 minutes.
Now, apply SR Composiv on the conditioned sur­face. Observe a layer thickness of min. 0.2 - max.

0.5 mm. The processing time is approximately 3
minutes. Subsequently, polymerize with light in the
Spectramat for 4 minutes or the Lumamat 100 for
11 minutes (P2). If other devices are used, observe
the instructions of the manufacturer.

Can Telio Lab and Telio CAD be layered over
and/or characterized with light-curing materi­als?

– Telio Lab and Telio CAD can only be layered

over with light-curing veneering materials. Telio
Lab LC Transpa material in conjunction with
SR Composiv as a bonding agent between the
PMMA resin and the composite veneering
material is suitable for the esthetic individualiza­tion of the incisal third in anterior restorations.

– Occlusal veneers in molars are contraindicated.

The layer thickness should not exceed 1.5 mm.

General information

What type of restorations can be fabricated
with Telio Lab?

– Temporary application:

Crowns and bridges (metal-free / metal­supported)

– Permanent application:

Supplements to artificial teeth in removable
dentures

Can Telio Lab Incisal be used for the individu­alization of the incisal area of a Telio CAD res­toration?

Yes. However, the following processing guidelines
have to be observed:
– Blast the ground surface with pure Al

size 100 µm and 2 bar/29 psi pressure, and

2O3

, grain

clean. Apply Telio Lab Cold Liquid by means of
a brush and let it react for min. 2 to
max. 4 minutes before starting the application
of Telio Lab Incisal materials.

– The Telio Lab Incisal materials can be applied by

means of the silicone key technique or free
layering technique.

– The overall layer thickness of the restoration

should not be less than 1.5 mm.

Must SR Gel always be used?

For the tempering of Telio Lab LC Transpa and Telio
Lab LC Base, SR Gel must always be used. If this is
not done, the inhibited layer will be too thick,
which may lead to clinical failure.
