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/YML (with a thickness of less than 1.2 mm).

Follow the Instructions for Use of the restorative material. In the absence of specific 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, hydrofluoric acid etching or air abrasion treatment may be used:

Acid Etching Treatment (e.g. conventional porcelain, lithium disilicate):
Etch the adherent surface with a hydrofluoric 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.

Although technically possible, we recommend to use “CLEARFIL™ CERAMIC PRIMER PLUS” to get optimal performance for glass ceramics.

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 10-15 mm. 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.

The “PANAVIA™ V5” Try-In Paste shades match the “PANAVIA™ Veneer LC” shades (in light-cured state) and allow for a simulation of the final appearance of the restoration. The “PANAVIA™ V5” 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.
