Q: What is the difference between Panavia F 2.0 and Panavia 21?
A: Panavia F 2.0 is a dual-cure, fluoride-releasing adhesive resin cement. Panavia 21 is self-cure and does not contain fluoride.
Q: How long does it take for Panavia F 2.0 to self-cure?
A: 3 minutes (in-vivo).
Q: What is the extra-oral working time of Panavia F 2.0?
A: Mixed Panavia F 2.0 paste will not set on the pad if it is thinly spread.
Q: What is the intra-oral working time of Panavia F 2.0?
A: 60 seconds. ED Primer II must be applied to the tooth and left for 30 seconds prior to cementation with Panavia F 2.0.
Q: Can I use my Plasma Arc (Xenon) and LED Curing Light with Panavia F 2.0?
A: Yes.
Q: What is the shelf-life of Panavia F 2.0??
A: 2 years. Refrigerate when not in use.
Q: How many applications are in a set of ED Primer II?
A: 200 – 400.
Q: What should I do if I froze my Panavia kit accidentally?
A: Unfortunately, the product will need to be discarded, as the ED Primer liquid will separate and will no longer be homogeneous.
Q: What is the difference between the Panavia F 2.0 Intro and Complete Kit?
A: The complete kit contains both Alloy Primer and Ceramic Primer.
Q: Can Clearfil SE Bond be used to bond amalgam?
A: No. When bonding amalgam, Clearfil Liner Bond 2V is recommended, or both types of Panavia.
Q: What is the best way to remove the excess cement from the margins?
A: Many dentists do a partial cure of the excess cement first, then remove it with an instrument. Please make sure not to cure it completely; otherwise, it can be difficult to remove (as all resin cements historically are).
Q: How far in advance can ED Primer II be mixed before application?
A: You can use ED Primer II for (5) minutes after mixing. After (5) minutes, the mixed ED Primer becomes more viscous and the bond strength to tooth structure is decreased.
Q: What shades of paste is Panavia F 2.0 available in?
A:
- TC= translucent A3
- Opaque= opaque A2 (slightly yellow)
- Light= translucent A2
- White= paper white (whiter than A1, more translucent than opaque)
Q: Is Alloy Primer included in either the Panavia 21 or Panavia F 2.0 kits?
A: This is the answer to the question asked above.
Q: Is Clearfil Ceramic Primer included in either the Panavia 21 or Panavia F 2.0 kits?
A: Ceramic Primer is not available in the Panavia 21 kit or the Panavia F 2.0 Intro kit. It is available in the Panavia F 2.0 Complete kit.
Q: Can SE Bond be used to cement crowns?
A: No, it cannot be used to cement crowns.
Q: How do I prepare my base metal posts when using Panavia F 2.0?
A: Sandblast the post first, then wash and dry it. Panavia F 2.0 paste is self-adhering to all dental alloys. There is no need to treat the surface of the post; however, ED Primer II should be placed into the canal prior to cementation. The Panavia F 2.0 paste will be used to coat the post prior to insertion.
Q: What is the pH of ED Primer II?
A: Approximately 2.4.
Q: What is the filler loading for Panavia F 2.0 paste?
A: The filler loading for Panavia F 2.0 is 59 vol% and 78 wt%.
Q: How do I prepare porcelain when using Panavia F 2.0?
A: Sandblast the interior surface of the restoration; use etching gel to activate and clean the surface; apply a silane coupling agent (ex. Porcelain Bond Activator plus SE Bond Primer or Ceramic Primer) to the internal surface of the restoration. The Panavia F 2.0 paste is then applied directly to the restoration. ED Primer II is used to treat the tooth surface prior to cementation.
Q: How do I prepare my Procera and In-Ceram crowns when using Panavia F 2.0?
A: Sandblast the interior surface of the restoration; ultrasonic wash and then dry. Panavia F 2.0 bonds directly to high-strength ceramics (e.g. In-Ceram and Procera). Apply ED Primer II to the tooth surface prior to cementation. There is no need for etching or silanating the internal surface.
Q: Silane coupling agents are not recommended for use with high-strength ceramics. Why can Clearfil Ceramic Primer be used to treat Zirconia and Alumina restorations?
A: Clearfil Ceramic Primer contains the adhesion monomer included in Panavia resin cements (MDP) which bonds to metals, as well as high-strength ceramics (Zirconia & Alumina). MDP activates the silane, which makes it multi-use.
Q: Can the SE Bond Primer be used instead of ED Primer ll for Panavia F 2.0?
A: No. The composition of SE Bond primer is adjusted only for SE Bond. If it is used with Panavia F 2.0, performance will not be as good. SE Bond primer does not consist of the catalyst which is contained in ED Primer II for accelerating the cure of Panavia F 2.0.
Q: Does this acidity cause any clinical problems after the tooth is restored?
A: No. The pH of ED Primer II increases as it dissolves into the tooth, yet is neutralized by calcium ions. When composites and bonding agents polymerize they are inert; therefore, they do not cause pulpal irritation. Pain in the pulpal tissue occurs when the dentin is not completely sealed. It does not occur from a reaction to the composite or bonding agent.
Q: Is my ED Primer defective if it turns brown? Will it affect the bond strength?
A: If the ED Primer II is not expired and has been stored in the refrigerator, then there is no problem with the bond strength and curing time, even if the ED Primer’s colour becomes light brown. This colour change is due to the self-cure initiator.
Q: How do these shades translate to those on the Vita Shade Guide?
A:
- TC is close to a translucent A3;
- Opaque is a non-translucent, yellowish-white, closest to A2;
- Light is close to a translucent A2;
- EX/White is whiter than A1 (almost like the whiteness of paper).
Q: Can I use Liner Bond 2V primer with other bonding agents or resin cements?
A: No. Liner Bond 2V primer is formulated to work exclusively with the Liner Bond 2V system.
