Product information

Material

The Telio products are compatible with each other and their shades are optimally coordinated.

Telio CS C&B

is a self-curing composite material for high-quality temporary crown and bridge restorations and is supplied in five shades (BL3, A1, A2, A3, A3.5). Telio CS C&B provides a high accuracy of fit and allows stress-free restorations to be fabricated even in multi-unit constructions, as, in addition to the high stability, the material features low polymerization shrinkage and absorbs little water.

Telio CS Desensitizer

is a solution to prevent and/or reduce dentinal hypersensitivity and postoperative sensitivity. In general, Telio CS Desensitizer is suitable to condition and desensitize exposed or ground dentin surfaces (dressing for prepared cavities and teeth). Dentin wounds may be treated before the incorporation of the Telio temporary restorations in order to prevent and minimize hypersensitivity. The desensitizer can be applied with temporary restorations, cementation of prosthetic work, during direct restorative therapy as well as for sensitive cervicals.

Telio CS Link

is a dual-curing (light- and self-curing) temporary composite cement used to seat temporary restorations (wear period of less than 6 weeks). Due to the two translucent shades (A3 & Transparent), an esthetic integration of the restoration is achieved. Telio CS Link is free of eugenol and therefore also suitable if all-ceramic restorations or lab-fabricated composite restorations are adhesively placed later.

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 any time. Stains and/or layering materials can be used to apply final esthetic optimizations.

Product information

mportant processing restrictions

If the following restrictions are not observed, successful working with the Telio materials cannot be ensured:

• Telio CS C&B and Telio CAD must not be used

to fabricate final restorations.

• Telio CS Link must not be used for the

permanent cementation of restorations.

• The Telio material should not be used if a

patient is known to be allergic to any of its ingredients.

• The required minimum thicknesses must be

observed.

• Staining/layering of Telio CAD using materials

that are not approved and/or recommended.

• Milling the Telio CAD blocks in a non-

compatible/non-authorized CAD/CAM system.

• Do not inhale grinding dust during finishing.

Use exhaust air discharge and dust mask.

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.

cause slight irritation and in rare cases may lead to a sensitization to methacrylates after repeated skin contact.

– Commercially available medical gloves do

not provide protection against the sensitizing effect of methacrylates.

– Telio CS Desensitizer contains glutaraldehyde

and is harmful if inhaled or swallowed. Prevent contact with skin, mucous membranes and eyes. If the material should accidentally come in contact with the eyes, immediately rinse with copious amounts of water and consult a physician. Repeated skin contact and inhalation may cause sensitization.

– Telio Activator contains methyl methacrylate

(MMA). Skin contact may cause sensitization.

– Telio Activator is only for extra-oral

application.

– MMA is highly flammable and irritating

(flash point: +10 °C/50 °F). – Irritating to eyes, respiratory organs and skin. – Do not inhale vapours. – Keep away from sources of ignition. Do not

smoke. – Prevent contamination of the sewage

system. – Take measures against electrostatic charge. – Do not inhale resin dust during finishing of

Telio CAD – use exhaust air discharge and

Shade determination

Shade determination of the natural tooth

After tooth cleaning, the tooth shade of the nonprepared tooth and/or the adjacent teeth is determined with the help of a shade guide. Individual characteristics have to be considered when determining the tooth shade (e.g. cervical shade). In order to achieve the best possible true-tonature results, shade determination should be carried out at daylight. Furthermore, the patient should not wear clothes of intensive colours and/or lipstick.

Minimum material thicknesses / layer thicknesses

The design of the restoration is the prerequisite for successful temporary restorations and also paves the way for the incorporation of the permanent restoration.

The following basic guidelines have to be observed:

• In large preparations and for partially veneered

restorations, the excess available space must be compensated by the correspond-ing dimensions of the stable 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 to support and reinforce the shape and cusps of the restoration is constructed with the integrated design tools of the different types of software used.

Telio CS Desensitizer

Application

Telio CS Desensitizer makes the temporary restoration phase more comfortable for patients, since it reduces the sensitivity of prepared, and in some cases exposed, dentin surfaces.

– Prepare cavity / abutment – You may take the impression at this stage or wait until you have

applied the desensitizer (see notes).

– The dentin surfaces should be dry and clean. Keep working field

dry (e.g. cotton rolls).

– Apply Telio CS Desensitizer:

Brush it into the dentin for 10 seconds using a suitable instrument (brush, applicator brush).

– Carefully disperse excess to a thin layer / dry with an air syringe.

Do not overdry the dentin.

– Fabricate the temporary restoration / provisionally cement restora-

tion (see notes).

Notes

– The application of Telio CS Desensitizer somewhat increases the

adhesion of the light-curing temporary inlay and onlay materials from Ivoclar Vivadent to the cavity walls. Nevertheless, they can be removed at the second appointment without difficulty.

– If light-curing temporary C&B materials are used, Telio CS

Desensitizer should be applied after the fabrication of the temporary. If you apply Telio CS Desensitizer prior to fabricating the temporary, the material may stick to the tooth structure when the impression is repositioned into the oral cavity during the setting/light-curing procedure and may be difficult to remove.

– The application of Telio CS Desensitizer during temporary fabrica-

tion does not affect or limit the choice of the cementation system or the success of the cementation procedure in the second appointment. Both conventional and adhesive cementation systems can be used for cementation purposes.

– The application of Telio CS Desensitizer to enamel does not create

any problems and does not affect the subsequent steps of the treatment or the materials being used (thoroughly remove excess desensitizer / dry).

– Telio CS Desensitizer can be applied before or after impression-

taking. The layer thickness is very thin, so that the accuracy of fit is maintained even if the desensitizer is applied after the impression-taking. Interaction of the desensitizer with impression materials are not known (if applied before impression-taking).
