    Q: What is PANAVIA™ F 2.0?

    A: PANAVIA™ F 2.0 is a universal dual-curing (light- and/or self-cure) resin based cement system for metal, ceramic, hybrid ceramics (e.g. EASTENIA C&B), composite resin and metal restorations.  PANAVIA™ F 2.0 releases fluoride and can be light-cured by halogen or LED.  [Note: Due to low curing depth, opaque paste can not be light-cured.]

    PANAVIA™ F 2.0 kit consists of ED PRIMER II, PANAVIA™ F 2.0 paste, PANAVIA™ F 2.0 OXYGUARDTM II, ALLOY PRIMER, and some accessories.

     

    Q: What is the difference between PANAVIA™ F 2.0 and PANAVIA™ 21?

    A: PANAVIA™ F 2.0 is a dual-curing (light- and/or self-cure) resin cement with fluoride releasing property.  PANAVIA™ 21 is a self-curing resin cement.

     

    Q: What is the advantage compared to other regular resin cement?

    A: PANAVIA™ F 2.0 has been regarded as a guarantee for permanent adhesive technique in the area of all-ceramics and metal restorations, especially for high-quality and difficult restorations. It is recommended by leading universities as a premium product.

     

    Q: What are the clinical applications?

    A: PANAVIA™ F 2.0 is indicated for the following applications:

    • Cementation of crowns, bridges, inlays and onlays made of ceramic, hybrid ceramics, composite resin or metal
    • Cementation of veneers
    • Cementation of adhesion bridges
    • Cementation of metal cores, resin cores, metal posts or glass-fiber posts
    • Amalgam bonding

     

    Q: Why should eugenol-containing materials (e.g. temporary cement) not be used?

    A: Eugenol retards the curing process. As a result, the bonding strength and mechanical properties will decrease.

     

    Q: Why should hemostatic agents containing ferric compounds not be used?

    A: These materials may impair adhesion and may cause discoloration at the tooth margin or surrounding gingiva due to ferric ions that may remain.

     

    Q: Could you tell me the pH of ED PRIMER II?

    A. Approximate pH is 2.4 after mixing ED PRIMER II Liquid A and Liquid B.

     

    Q: Which shade is available?

    A. PANAVIA™ F 2.0 Paste is available in 4 shades; TC (tooth color), Light, White, and Opaque. The information is listed on not only the package but also on the PANAVIA™ F 2.0 B Paste itself.  Please refer to the following table for the shades of adhesive cements and applicable cases:

    Cement shade Restoration

    TC, Light

    White

    Opaque

    Crown, bridge, inlay or onlay made of metal recommended recommended not recommended
    Crown, bridge, inlay or onlay made of ceramic, hybrid ceramics or composite resin recommended adequate adequate
    Veneer recommended adequate adequate
    Core or post recommended recommended recommended
    Adhesion bridge and splint anterior adequate not recommended recommended
    Adhesion bridge and splint posterior recommended recommended recommended
    Bonded amalgam restoration recommended recommended not recommended

     

    Q: How to dispense the pastes from the syringe?

    A. Align marking on the nut with the deference line on the plunger and turn the syringe to dispense the necessary amount of A Paste. Minimum turn of the syringe should be half a turn. Then, equal amount of B Paste should be dispensed. 
    The amount of paste dispensed at last rotation of the syringe could be inaccurate.  Therefore, discard the syringe before using the last portion.

     

    Q: What is the necessary amount of paste dispensed from the syringe?

    A. The necessary amount of paste for a typical application is:

    Number of rotations of syringe

    Applications

    Half a turn Inlays and onlays
    1 turn Crowns

     

    If the paste is dispensed by turning the plunger a quarter of a turn, the performance of the product could be impaired when the paste hardened.

     

    Q: How many restorations can be cemented with the paste?

    A: Approximately 45 crowns. For inlay, approximately 90 inlays. Of course, the number depends on the size of the restoration.

     

    Q: What is the working time after mixing the pastes?

    A: The paste must be used within 3 minutes after mixing.  If the mixing is insufficient, the working time of the mixed paste could vary. Therefore, mix sufficient A Paste and B Paste on the mixing plate for 20 seconds.

     

    Q: Could you tell me the pretreatment of silane based ceramic restorations?

    A: As necessary, sandblast the restoration surface using 30-50 mm alumina powder at an air pressure of 0.1-0.4 MPa (1-4 kg/cm2). After sandblasting, clean the prosthetic restoration by using an ultrasonic unit for 2 minutes, followed by drying it with an air steam. Next, apply phosphoric acid (e.g. K-ETCHANT GEL) to the adherent surface, leave it for 5 seconds, then wash the surface with water and dry the surface. Dispense the necessary amounts of CLEARFILTM CERAMIC PRIMER into a well of the mixing dish immediately before application. Apply CLEARFILTM CERAMIC PRIMER to the internal surface of the restoration with a disposable brush tip. After application, dry the entire restoration surface sufficiently using mild, oil-free air flow. You may also follow the manufacture's instructions for use for the restoration.

     

    Q: Could you tell me the pretreatment of zirconia or alumina based ceramic restorations?

    As necessary, sandblast the restoration surface using 30-50 mm alumina powder at an air pressure of 0.1-0.4 MPa (1-4 kg/cm2).  The air pressure should be properly adjusted to suit the material and/or shape of the prosthetic restoration, using caution to prevent chipping. After sandblasting, clean the prosthetic restoration by using an ultrasonic unit for 2 minutes, followed by drying it with an air steam. There is no need for further surface treatment.

     

    Q: Could you tell me the pretreatment of precious metal restorations?

    As necessary, sandblast the restoration surface using 30-50 mm alumina powder at an air pressure of 0.1-0.4 MPa (1-4 kg/cm2). After sandblasting, clean the prosthetic restoration by using an ultrasonic unit for 2 minutes, followed by drying it with an air steam. Then, apply ALLOY PRIMER to the restoration surface with a disposable brush.

     

    Q: How should I treat the surface of a glass-fiber post?

    Apply phosphoric acid (e.g. K-ETCHANT GEL) to the post surface with a disposable brush, leave it for 5 seconds, then wash the surface with water and dry the surface. Next, apply CLEARFILTM CERAMIC PRIMER to the post surface with a disposable brush tip.

    Don't sandblast glass-fiber posts; this could damage the post fibers. Damage to the fibers degrades the strength to adhesive resin materials.

     

    Q: After the cementation of cores or posts, how to proceed with the core-build up?

    Place build-up composite resin (e.g. CLEARFILTM PHOTO CORE or CLEARFILTM DC CORE AUTOMIX) directly on PANAVIA™ F 2.0, then light or self-cure.

     

    Q: How should the PANAVIA™ F 2.0 Paste be cured?

    A: Cure the mixed PANAVIA™ F 2.0 Paste along the cement margin, using either of the following two methods:

    (1) Light-curing method: Light-cure the paste along the cement margin with a dental curing unit (Conventional halogen, Fast halogen, LED, and Plasma arc).  The Opaque paste should not be light-cured due to a low curing depth. Therefore, the paste should cure in its self-curing mode.

    (2) Self-curing method: Use PANAVIA™ F 2.0 OXYGUARD II at the margin areas.  After 3 minutes, remove OXYGUARD II with a cotton roll and water spray.

     

    Q: What is the shelf-life of PANAVIA™ F 2.0?

    A: PANAVIA™ F 2.0 should be used by the expiration date indicated on the label of each container.

     

    Q: What is the storage condition of PANAVIA™ F 2.0?

    A: PANAVIA™ F 2.0 should be stored in a refrigerator (2-8oC/36-46oF) when not being used. Please keep away from extreme heat or direct sunlight. The bottle or syringe cap should be replaced as soon as the resin has been dispensed from the bottle or syringe. This prevents evaporation of volatile ingredients.

     

    Q: Does PANAVIA™ F 2.0 have radiopacity?

    A: Yes. The radiopacity of PANAVIA™ F 2.0 shows 120 Al% based on ISO 4049:2000.

     

    Q: What is the film thickness of PANAVIA™ F 2.0?

    A. It is 24 μm based on ISO 4049:2000.

     

    Q: What is the amount of filler in PANAVIA™ F 2.0?

    A: The total amount of inorganic filler is approx. 59vol% (78wt%). The particle size of inorganic fillers ranges from 0.04 μm to 19 μm.
