Impression material should be stored in a dry place at room temperature. Direct sunlight and extreme temperature changes must be avoided. If storage temperature is clearly below/above room temperature, bring the impression material to room temperature before use. If the impression material is too cold during impression taking, the setting times will be longer than stated, and if you are working in a (too) warm room, the processing and setting times will be much faster than normal.

Reasons for delayed / no setting and setting times longer or shorter than indicated include:

• The material could be too warm or too cold. Always bring the impression material to room temperature first: working and setting times are affected by higher or lower temperatures.
• With a hand-mixed A-silicone putty, it is important that the ratio of catalyst to base material is 50/50%; otherwise, setting times may be affected.
• Do not use latex gloves.
• Discard a little material at first (jumbo cartridge) / before each (50 ml cartridge) use.
• Do not mix different types of material. Use dedicated accessories (e.g. application syringes) for each type of material (e.g. polyether vs. A-silicone), do not use accessories “contaminated” with other types of materials
• Retraction agents containing ferric sulfate, epinephrine or aluminium chloride may have a negative effect on the setting. When using such materials, rinse area thoroughly.

No adhesive bonding:

• The adhesive must be dry before the tray is filled with impression material.
• To allow the tray adhesive to work effectively, ensure that there is no inhibition layer on the surface of custom trays. If necessary, remove the smear layer with alcohol or mechanically.

General tips:

• Leave the mixer in the material when dispensing to avoid air bubbles.
• To ensure best results, always use original mixing tips.

• Always follow manufacturer guidances.

Yes, absolutely. A mixing tips’s diameter and length must be matched to the material. Some mixers available on the market appear to be suitable, but do not mix homogeneously. To ensure best results, always use original Kettenbach Dental mixing tips. Compatible accessories are always displayed on the product sites.

Do not use latex gloves. Latex has a negative effect on the curing of A-silicones and Identium® and can cause poor-quality impressions.

We recommend using a custom tray when taking impressions with impression posts and for fixation impressions. Prefabricated trays can also be customized by damming around the palate area or on the end of the tray for a greater build-up of pressure. The distance between tray wall and tooth equator should be at least 3 times greater than the depth of the undercut.

A good individual tray requires a preliminary impression. If trays are printed, it is preferable to make the preliminary impression with a scan-optimised impression material.

Any inhibition layer on the plastic individual tray can interfere with the setting of the impression material and must be thoroughly removed before use.

Every impression material shrinks (minimally) and in order to make this shrinkage predictable and controllable, it is important to be able to create an even impression material thickness between the elements and the inside of the impression tray. Because adhesion occurs between the tray and the impression material, this material shrinkage always occurs towards the tray wall. The more shrinkage the impression material has, the greater the cement thickness will be when placing the crown and bridge work. It is important that the tray is not too tight; in addition to blocking out undercuts, sufficient impression space (at least 4 to 5 mm) must also be left.

We generally recommend the use of impression trays that allow sufficient pressure to build up, especially with medium (Type 2) and heavy body (Type 1) impression materials. Closed trays as well as custom trays are suitable; perforated trays are not recommended. When selecting a ready-made tray, it is important to choose a well-fitting, rigid tray. Stock trays can be customized for higher pressure build-up by blocking out the palatal area or the posterior end of the tray.

When selecting the tray size, always ensure that the distance from the tray wall to the tooth equator is at least three times the depth of the undercut. It is of course also important to use a tray that fits as well as possible, which provides adequate but not excessive space and thus permits optimal pressure build-up.

Before taking an impression, any bleeding must be brought under control. Retraction cords and liquids containing ferric sulfate, epinephrine or aluminium chloride can lead to setting inhibition. Therefore, after using such materials, the contaminated areas must be thoroughly rinsed. Remove retraction cord or paste and any cotton rolls from the patient’s mouth just before inserting the tray into the patient’s mouth.

• Select appropriate impression tray, ensure proper size and fit.
• Apply Kettenbach Dental Universal Adhesive 5 min before taking the impression.
• Prepare the oral situation: Block out large undercut areas, expand the sulcus and control bleeding. For subgingival preparation margins, use retraction cords. If applicable, clean the prepared stumps.
• Prepare impression material and accessories: Bring material to room temperature. Depending on type of cartridge, discard some material. Mix the material homogeneously and fill the tray completely and continuously without interruption. Leave the mixing tip in the material when filling the tray to avoid bubbles. For hand-mixed putties, maintain a 1:1 ratio of catalyst to base material. Do not use latex gloves or polyether “contaminated” accessories. If applicable, thoroughly remove any inhibition layer on the surface of custom trays.
• Insert the filled impression tray into the patient’s mouth as vertically as possible to the occlusal plane. Set a timer according to the indicated setting time. Hold the tray in position, do not fully depress. Do not hand the impression tray over to others.
• After the material has completely set, remove the impression tray as vertically as possible to the occlusal plane with a slight rotational movement.
• Rinse, dry and disinfect the impression.

General guidance: Always follow manufacturer instructions and observe working and setting times. To ensure best results, use original mixing tips.

Visalys® CemCore from Kettenbach Dental is a dual-curing luting composite designed for safe and predictable cementation of all indirect restorations. This 2-in-1 product can also be used for fabricating core build-ups and build-up fillings. The unique, patented Active-Connect Technology eliminates typical conflicts and enables optimal mixing of the somewhat hydrophobic composite Visalys® CemCore with the hydrophilic Visalys® Tooth Primer on the damp tooth surface, resulting in a permanently high adhesive bond. Visalys® CemCore features excellent flow properties, is radiopaque, bisphenol-A-free, and ready to use.

The correct procedure for taking an alginate impression for an individual edentulous tray.

Determine the tray size based on the old denture. If in doubt, choose one tray size larger for the upper jaw and one tray size smaller for the lower jaw. For a large jaw, it is best to use a tray for a dentate jaw and apply yellow beeswax to the trigonea. Coat the trays with the appropriate adhesive and make the alginate stiff. If using Silginat® (an A-silicone) for the impression, first coat the trays with Panasil® adhesive.

Before processing Identium® impression material, first bring the impression material to room temperature. Processing and curing times are affected by higher or lower temperatures. Do not use latex gloves or a polyether “contaminated” impression syringes. First remove the inhibition layer (lubricant layer) from an individual tray before taking an impression.

Temperature (warmer or colder than room temperature), latex and a polyether “contaminated” impression syringe, as well as the inhibition layer (lubricating layer) of a temporary restoration material left behind on the preparation, can adversely affect the curing of the Identium® impression material. Furthermore, some retraction agents may have a negative effect on curing; however, we have not received any complaints about this in relation to Kettenbach impression materials for decades.

Visalys® CemCore is the best choice for preventing tooth fractures for several reasons: Thanks to its extremely low water absorption properties, the risk of tooth fracture is reduced. Visalys® CemCore is a 2-in-1 dual-curing luting composite and core build-up material. It offers excellent dimensional stability and, with its unique Active-Connect Technology, guarantees optimal adhesive bond for all indirect restorations. With Visalys® CemCore, you really are on the safe side: The material is also 100% free from bisphenol A.

It is important to determine whether the bonding failed on the tooth side (with residual composite cement on the resin-bonded bridge) or on the restoration side (with residual composite cement on the tooth surface).

Adhesive bridges can be somewhat challenging, as they require high bond strength while offering only a limited surface for adhesion. In this case, we recommend selectively etching the enamel surface (see the information in the instructions for use).

For the Maryland bridge itself, we recommend following the established procedures, depending on the material of the bridge:

• In the case of zirconium dioxide: sandblasting.
• In the case of silicate ceramic: etching with hydrofluoric acid.

In both cases, Visalys® Restorative Primer is applied as usual.

The pretreatment of the restoration surface / resin-bonded bridge is very important, as increasing the surface area (through sandblasting or hydrofluoric acid etching) is the key factor for successful bonding.

Before cementation with Visalys® CemCore, Visalys® Tooth Primer is first applied to the tooth surface.

This combination is contraindicated and not according to the instructions for use. Adhesion may be compromised.
In a bonding test (ISO 29022), the combination of Visalys® Tooth Primer and Visalys® CemCore achieves sufficient bonding strength on all surfaces (≥ 5 MPa). On glass ceramics, adhesion is only minimally above the threshold value of 5 MPa, as without the silane contained in Visalys® Restorative Primer, proper bonding is not possible.
The values, however, are significantly poorer than the intended combination of Visalys® Restorative Primer and Visalys® CemCore.
Always choose the correct material combination (Visalys® Tooth Primer for tooth substrate only, Visalys® Restorative Primer for restorative materials). The IFU and step-by-step instructions are helpful tools to guide you through the process.

Before cementation with Visalys® CemCore, Visalys® Tooth Primer is first applied to the tooth surface.

The Visalys® Tooth Primer can also be used as an adhesive/primer with Visalys® Core. Use with other composites is not indicated.

Yes. Visalys® CemCore is also suitable for attachment to common implant abutments. The abutment must be pre-treated according to the specifications of the respective manufacturer.

No. Although the use of a restoration primer is mandatory, other restoration primers suitable for the respective surface can also be used.

Yes. The excellent adhesion values to the tooth substance can only be achieved by combining Visalys® CemCore and Visalys® Tooth Primer.

No, light curing is not required. This means that the primers are also effective in areas that are difficult for light to access (e.g. root canal) and premature curing by ambient light is impossible. Blockage and fitting problems caused by too thick primer layers are avoided. In addition, one work step is omitted.

Accidental light curing of the primers is not harmful.

For pre-treatment, the instructions of the post manufacturer must be observed. If an adhesive/primer is required, the Visalys® Restorative Primer is suitable.

Yes. The root canal must be cleaned and dried. The surfaces in the root canal are then wetted with the Visalys® Tooth Primer.

Glycerine can be used to cover the cement joint excellently.

All remnants of the temporary cement must be removed. The stump surface is cleaned with water spray and then dried. Any remaining tooth structure must be pre-treated with the  Visalys® Tooth Primer according to the instructions. Subsequently, the restoration can be directly attached with Visalys® CemCore without further pre-treatment of the composite surfaces.

Dual-curing composites without Active Connect Technology often do not cure completely on acid-etched tooth surfaces and/or those pretreated with adhesive or primer and require an additional activator (referred to as self-cure activators (SCA)).

Cementation composites must be as hydrophilic as possible while also having very good flowability. Core build-ups require a high degree of stability and a material that swells as little as possible. Kettenbach Dental has developed a groundbreaking technology that simply eliminates the conflicts: Active-Connect-Technology (ACT) allows optimal mixing of the somewhat hydrophobic cementation composite Visalys® CemCore with the hydrophilic Visalys® Tooth Primer on the damp surface of the tooth. The innovative composite achieves a high adhesive strength despite its hydrophobic properties while also avoiding swelling.

After the contact of Visalys® CemCore (hydrophobic) with the water-based VISALYS® Tooth Primer (hydrophilic), which penetrates deep into the tooth surface, the phase transfer catalyst is activated:

Visalys® Temp from Kettenbach Dental is ideal for the fabrication of temporary crowns, bridges, inlays, onlays, and veneers. It is perfectly suitable for long-term temporaries and has exceptional fracture resistance and very good marginal stability. It offers excellent flow, thixotropy, stability, and user-friendliness. It has a low smear layer and finishes quickly and beautifully to a high gloss. Its natural translucency and opalescence provide for seamless integration in the oral situation, and it is a safe choice as it does not contain bisphenol A.

Visalys® Temp from Kettenbach Dental is a reliable and aesthetic restorative material. It is exceptionally stable and user-friendly, making it ideal for the fabrication of temporary crowns and bridges (as well as provisional inlays, onlays, and veneers). Offering exceptional fracture resistance and stability, it carries a low risk of fracture and is also suitable for long-term temporary restorations.

The ideal time for removal depends on the personal preference of the user: Some users prefer it when the temporary is still relatively elastic – others want the temporary restoration to be very hard when it is removed from the mouth. On the other hand, the individual oral situation must also be taken into account: If, for example, there are large undercuts, it is better to remove the temporary restoration at an early stage.

Yes.

Yes. Any composite can be used for repairs, e.g. Visalys® Bulk Flow.

Yes. Visalys® Temp is compatible with any impression material. However, an A-silicone impression is recommended (e.g. Silginat® or Panasil® Putty), as it can be stored and reused for possible repairs or for remaking the provisional.

In principle, yes. Cross-toothed burs made of stainless steel have proven particularly effective.

Yes. However, ensure that eugenol-free temporary cements are used if it is planned to incorporate the subsequent permanent restoration of a composite cement. Eugenol (clove oil) can impair the chemical curing of the composite cement.

In principle, yes. Cotton buffs have proven particularly effective.

Burs can quickly become dull if the smear layer has not been removed beforehand. Therefore, removing the smear layer before milling is definitely recommended. With Visalys® Temp, it can be done very quickly with a disinfectant wipe, for example.

Nitrile can interfere with the bonding of Visalys® Temp (and other temporary crown and bridge materials). Although direct contact with the glove before curing is very unlikely, vinyl or latex gloves are recommended.

CAVE: Considering your workflow, keep in mind that latex gloves can have a negative effect on the curing of A-silicones.

The curing of the temporary restoration should be checked extraorally, e.g. by means of a material sample on the glove, and intraorally. As soon as the material is so hard that it can be easily pressed in with a fingernail or a probe and an impression remains, the temporary restoration can be removed from the patient’s mouth at the earliest.

Visalys® Temp continues to harden afterwards. After approx. 4 minutes, the material is hard enough that it can be finished well and no longer deforms even under high pressure.

Yes. Visalys® Temp is a composite as well and could chemically interact with existing composite restorations. Therefore, all composite fillings and core build-ups should be insulated beforehand, for example with petroleum jelly (Vaseline).

Newly created temporary restorations still contain the lubricating layer, which reacts during a repair or addition, thus creating a chemical compound. This is not the case with older temporary restorations, so milling and bonding serve to create a better chemical bond.

No. Visalys® Temp is purely self-curing.
