FAQ

PANAVIA™ Veneer LC

PANAVIA™ Veneer LC is a light-cure adhesive resin cement system. It consists of the PANAVIA™ Veneer LC Paste
(a light-cure cement paste), CLEARFIL™ CERAMIC PRIMER PLUS (a silane, zirconia & metal primer), K-ETCHANT
Syringe (Phosphoric Acid), and PANAVIA™ V5 Try-in Paste. CLEARFIL™ Universal Bond Quick or PANAVIA™ V5
Tooth Primer can be chosen for tooth treatment.

Cementation of ceramic and composite inlays, onlays and laminate veneers with less than 2 mm thickness of the following materials: silica-based ceramics (e.g. conventional porcelain, lithium disilicate), hybrid ceramics, composite resin and KATANA™ Zirconia STML/UTML (with a thickness of less than 1.2 mm).

Follow the Instructions for Use of the restorative material. In the absence of specifi c instructions, we recommend the
following procedures and application of the provided CLEARFIL™ CERAMIC PRIMER PLUS: If the adherent surface
is silica-based ceramic (e.g. conventional porcelain, lithium disilicate), hybrid ceramic or composite resin: Based on the
type of restoration, hydrofl uoric acid etching or air abrasion treatment may be used:

• Acid Etching Treatment (e.g. conventional porcelain, lithium disilicate):
Etch the adherent surface with a hydrofl uoric acid solution in accordance with the Instructions for Use of the solution.
Rinse the adherent surface with water and dry.

• Air Abrasion Treatment (e.g. composite resin):
Roughen the adherent surface by blasting with alumina powder (30-50 μm) using air pressure of 0.1-0.2 MPa (1-2 kgf/
cm2, 15-29 psi, 1-2 Bar). The air pressure and powder size should be properly adjusted to suit the material and/ or
shape of the prosthetic restoration, using caution to prevent chipping. Clean the prosthetic restoration in an ultrasonic
cleaning unit for 2 minutes or with KATANA™ Cleaner with 10 seconds of rubbing and then rinse with water.

Yes, doing that would contaminate the restoration and, hence, decrease the bond strength. To remove the contamination, use KATANA™ Cleaner for 10 seconds with a rubbing motion then rinse with water until the color has been disappeared and dry the restorations to remove contaminants, or apply K-ETCHANT Syringe (Phosphoric Acid) for 5 seconds in case of non-zirconia restorations.

There are 2 ways to treat the prepared tooth: with the PANAVIA™ V5 Tooth Primer or CLEARFIL™ Universal Bond Quick.

  • a) PANAVIA™ V5 Tooth Primer: Etch the enamel with the K-ETCHANT (phosphoric acid) for 10 seconds, rinse and
    dry. Apply the Tooth Primer to the entire prepared tooth surface, with an applicator brush and leave it in place for 20
    seconds. Thoroughly dry the entire adherent surface sufficiently by blowing mild, oil-free air until all water is evaporated from the primer.
    b) CLEARFIL™ Universal Bond Quick: Selective etch the enamel with K-ETCHANT syringe (phosphoric acid) for 10
    seconds, rinse and dry. Apply BOND with a rubbing motion to the entire preparation with the applicator brush. No
    waiting time is required. Dry the entire cavity wall sufficiently by blowing mild air for more than 5 seconds until BOND does not move.
    When cementing laminate veneers, there is no need to light-cure BOND prior to seating the laminate veneers. It should be cured after seating the laminate veneers with the PANAVIA™ Veneer LC cement. When cementing inlays or onlays,
    BOND should be light-cured before seating the restoration. Please confirm the curing time by referencing the Instructions for Use.

In terms of bond strength, both are similar and provide excellent results. Nevertheless, the PANAVIA™ V5 Tooth Primer
will provide a “touch cure” mechanism that will seal the bonding interface before the final light curing. Additionally, while
the application time is shorter with CLEARFIL™ Universal Bond Quick (no waiting time versus 20 s), there is a longer
working time under ambient light with the PANAVIA™ V5 Tooth Primer (200 seconds vs 160 seconds with the BOND).

PANAVIA™ Veneer LC offers the ideal paste consistency, not being too high or too low as several competitive products. This will facilitate the dispensing of the paste onto the restoration and smooth seating of such restoration. A low film thickness and long working time are also advantages over competitive products. In addition, in case of using it with the PANAVIA™ V5 Tooth Primer, the “touch-cure” mechanism will provide bonding interface sealing.

One of the following two techniques can be used:
Tack-Cure Clean-Up Technique: Light-cure any excess cement in several spots for 1 second at a distance of 10-15mm. Hold the prosthetic restoration in position, remove the tack-cured excess cement using a dental instrument.
Wet Clean-Up Technique: Any excess cement remaining at the margins can be removed with a small brush, foam pellet, dental floss or dental explorer.
Regardless of the technique used, final curing will be required as the next step. Please refer to the Instructions for Use.

The use of a protective gel, like PANAVIA™ F 2.0 OXYGUARD II, is beneficial to prevent the forming of an oxygen inhibited layer thus helping to create smooth margins.

There are 4 shades of PANAVIA™ Veneer LC Paste available: Clear, Universal (A2); White and Brown (A4). Each shade has a corresponding glycerin based, water soluble Try-In Paste.

Use the PANAVIA™ V5 Try-in Paste instead of the cement paste when you try in a restoration, to check the aesthetics of the restoration. The Try-in Paste cannot be (light) cured, and can be removed easily with water.

Yes, PANAVIA™ Veneer LC Paste is color stable.

Since PANAVIA™ Veneer LC Paste is only light curing, no amine reducing agent based redox curing system is included avoiding unwanted discoloration over time.

The total amount of inorganic filler is approximately, 66 wt%, 47 vol%. The particle size of inorganic fillers range from 0.05 μm to 8 μm.

PANAVIA™ Veneer LC Paste has spherical silica and nano cluster fillers. This provides a paste which is not runny, has excellent handling, and resistance to sagging.

PANAVIA™ Veneer LC Paste film thickness is around 8 μm.

Zirconia should not be used because it may not have sufficient translucency. However, zirconia of our products with high translucency (KATANA Zirconia STML/UTML, KATANA Zirconia Block STML) can be used with a thickness of
less than 1.2 mm.

PANAVIA™ Veneer LC has excellent bond strength to several substrates (e.g. enamel, dentin, lithium disilicate, KATANA™ Zirconia, feldspar ceramic) at a similar level to the acclaimed PANAVIA™ V5.

Approximately 20-30 teeth for laminate veneer.

No, the PANAVIA™ Veneer LC Paste tips are specially designed for an easy extrusion and application and their gauge, which is 16 (1.65 mm in diameter) and differ from the CLEARFIL MAJESTY™ ES Flow ones.

The product should be stored in the refrigerator. All components stored in the refrigerator should be brought to room temperature for 15 minutes before use in order to restore its normal viscosity and curing properties.

The shelf-life of PANAVIA™ Veneer LC components is 36 months from date of manufacture with refrigeration.

PANAVIA™ SA CEMENT UNIVERSAL

It contains two types of adhesive monomers (“MDP” and “LCSi”) allowing adhesion to various types of prosthetic restorations without primer treatment. It also allows fast and easy clean-up of the excess cement. 

“MDP” provides high bond strength by chemical adhesion with its phosphate group to the surface of tooth structure, metal, metal oxide (zirconia, etc.). Furthermore, by incorporating proprietary long chain silane coupling agent “LCSi monomer”, it has the property of bonding to Silica-based ceramics(IPS e.max, porcelain etc.) without requiring primer treatment.

Universal: The shade is equivalent to A2, and it is recommended for a wide range of restorations.

White: High visibility, opaque for excellent discrimination from the tooth structure (for posts, etc.)

Translucent: High transparency, it is recommended for aesthetic restorations.

Yes, the shades are the same as in previous versions.

Automix: Approximately 20 cases (based on the number of tips attached to the paste separately)

Handmix: 60 cases (crown)

  • Working time (23℃/73°F): Handmix takes 2 minutes, Automix takes 1 minute.
  • Working time (in oral cavity): takes about 40 seconds (When used with CLEARFIL™ Universal Bond Quick, 30 seconds.)
  • Light-cure (removal excess cement): 2 to 5 seconds
    *When used in combination with CLEARFILTM Universal Bond Quick, 1 to 2 seconds
  • Self-cure (removal excess cement): between 2 – 4 minutes
    *Note: Please refer to the Instructions for Use for more detailed information.
  • Light-cure (final polymerization): 10 seconds
  • Self-cure (final polymerization): 37℃/99°F 5 minutes, 23℃/73°F 12 minutes

It is the first time to incorporate it in a resin cement paste for the purpose of providing adhesive property, but CLEARFIL MAJESTY™ ES Flow, etc. have been using it as a surface treatment agent of the fillers.

There is no difference in performance whatsoever. The basic composition is the same, therefore both have the same adhesive performance.

Regarding the working time, handmix takes two minutes and automix takes one minute.

When dispensing the cement from automix syringe, a mixing tip or endo tip must be used.

Store at a temperature of 2-25°C/ 36-77°F.
During storage, please avoid direct sunlight, dental light, extreme heat etc.

A1. Curing promoted by ambient light

The paste contains a light-cure catalyst that is highly photo-active, and the polymerization can be accelerated when exposed to strong light such as dental light during cementation. Please take measures to reduce the intensity of light by turning off the dental light at the time of operation. Also during and after paste mixing, any exposure to light such as direct sunlight or dental light promotes curing, so please perform the cementation operation promptly after mixing the paste.

A2. Curing promoted in intraoral environment

The curing of resin cements, such as PANAVIA™ SA Cement Universal, can be accelerated in intraoral environment where the temperature is higher than room temperature. In addition, curing of resin cements can be accelerated as well when the mixed paste is not in contact with air during the cementation procedure with prosthetic restorations. In particular, when cement is applied directly to the cavity, initial curing will start in about 40 seconds, so please perform cementation operation promptly (when used in combination with CLEARFIL™ Universal Bond Quick, the initial curing starts in about 30 seconds after cementation). As described in the Instructions for Use, the use of lentulo spiral can accelerate the polymerization of the paste beyond the desirable limits.

A3. Curing promoted by contact with water

The water drops adhering to the mixing pad or spatula may accelerate the curing, so if water drops are present, please wipe them off before use. When the product is stored in the refrigerator, to avoid water condensation, allow the product to come to room temperature for at least 15 minutes before use.

When removing the excess cement after tack-curing, hold the restoration in place to avoid the possibility of lifting the restoration, since there could be some insufficiently cured resin cement. If dental floss is used to remove the excess cement, it should be used in the direction that does not lift the prosthetic restoration.

In the case of cementation of non-translucent prosthetic restorations (e.g. metal crowns and inlays), the final curing time of 5 minutes after placement is necessary.

Please ensure that the light cure was done sufficiently on the entire surface and margins of the restoration. Additionally, in restorations with cores and posts, please allow at least 10 minutes before preparing the abutment tooth.

A1. Usage of eugenol-containing materials for pulp protection or temporary sealing, as it may inhibit the curing process of resin cement.

A2. Usage of hydrogen peroxide for cleaning cavities, as it may weaken the bond strength to the tooth structure.

A3.Usage of hemostatic agents containing ferric compounds as these materials may impair adhesion and may cause discoloration due to remaining ferric ions.

A4. Usage of hemostatic agents containing aluminum chloride. When using the above, minimize its quantity, and use caution to prevent contact with the adherent surface. Failure to do so might weaken the bond strength to the tooth structure.

A5. Contaminated cavity. If the cavity is extremely contaminated as in the case where the metal core is dropped, etc., clean it in accordance with the general regulations. In addition, residual amalgam or lining materials should be completely removed during cavity preparation to avoid poor adhesion.

A6. Unequal amount of Paste A & B is used. Make sure to dispense an equal amount of Paste A & B for mixing. If the amount of paste A & B dispensed is not equal, curing may be faster or slower and there is a possibility of poor polymerization. In the case of the automix type, before attaching a mixing tip or an endo tip, extrude small amount of the two pastes, making sure equal amounts are being dispensed through the two outlets of the syringe, and discard the test paste.

PANAVIATM SA Cement Universal does not cure properly (or cures very slowly) in room temperature and in air, because oxygen interrupts the curing of the resin (anaerobic curing). These are normal property of resin cements.

The picture shows the paste on the mixing pad. It cannot be cured in the red area, especially in air (oxygen). If the paste amounts are very small, the paste cannot be polymerized.

First, dispense small amounts of PANAVIATM SA Cement Universal paste with a mixing tip and leave for 5 – 10 min. Then check to see if the paste can be dispensed from the mixing tip. (If it is hard to dispense, it works correctly) The oxygen influence of the paste is avoided in the mixing tip. For the handmix version, the inner layer of the paste will polymerize, but the outer layer may remain soft (oxygen inhibition layer).

The final curing time is 10 seconds in case of the prosthetic restorations that are translucent.

The final curing time is 5 minutes after placement of prosthetic restoration for self-curing. In the case of the cores and dental posts, seat the restoration in place for approximately 10 minutes and make sure the cement has been completely cured before preparing the abutment tooth.

Although it is possible to apply cement to both prosthetic or abutment sides, curing is accelerated when applied to the abutment tooth (cavity) side. When inserting the paste directly into the cavity or root canal, placement of the prosthetic restoration should be done within 40 seconds (within 30 seconds when using CLEARFILTM Universal Bond Quick).

Yes, PANAVIATM SA Cement Universal can be bonded to both non-precious metal alloys and precious metal alloys.

Yes, it is possible. Primer treatment to the fiber post is unnecessary, but please clean it according to the Instructions for Use after the post trial.

PANAVIA™ V5

PANAVIA™ V5 is a dual-cure, fluoride-releasing, radiopaque resin cement with a single-bottle, self-etching primer and a single-bottle prosthetic primer. It is available in an automix delivery system.

Please follow the standard procedure I, A-5. “Application of Tooth Primer to the Prepared Tooth” in the Instructions for Use. Apply Tooth Primer to the entire prepared tooth, with an applicator brush and leave in place for

CLEARFIL™ CERAMIC PRIMER PLUS is a dental universal prosthetic primer that provides an enhanced adhesive surface to ceramic, hybrid ceramics, composite resin and metal.

CLEARFIL™ CERAMIC PRIMER PLUS provides the strongest bond strengths to IPS e.max (lithium disilicate)*. CLEARFIL™ CERAMIC PRIMER PLUS contains the Kuraray original MDP, providing an excellent bond strength. *Gordon J. Christensen clinicians

It cannot be used. Because the chemical polymerization catalyst used is different, sufficient adhesion cannot be guaranteed. We recommend the usage of CLEARFIL™ Universal Bond Quick to enhance bond strength to tooth structure.

CLEARFIL™ CERAMIC PRIMER PLUS contains MDP, and will bond directly to zirconia. It will also bond to a cleaned IPS e.max (lithium disilicate) surface.

The PANAVIA™ V5 paste employs the novel amine-free catalyst*, making it extremely color-stable.  There is virtually no post-cure color change.  This assures a consistent and predictable result each time. PANAVIA™

There are 5 shades of PANAVIA™ V5 paste available:  Universal (A2), Clear,  Brown (A4), White, and Opaque (self-cure only). Each shade has a corresponding Try-In Paste, which can be easily removed with water.

The clinical indications for PANAVIA™ V5 include: cementation of crowns; bridges; inlays/onlays; veneers; adhesion bridges and splints, prosthetic restorations on implant abutment and frames; posts/cores; and amalgam bonding.

Yes, auto-mixing Paste A and Paste B guarantees a dual-cure effect.

No, it is not mandatory to use Oxyguard II.

No, in case of most indications. Yes, if the adherent surface is uncut enamel, or when cementing an adhesion bridge or veneers.

Yes. For example, CLEARFIL™ Universal Bond or other prosthetic primers can be used.
