PANAVIA™ SA Cement Universal

How to Use

Frequently Asked Questions

We've put together a complete list of answers for the most pertinent questions.

What are PANAVIA™ SA’s main features?

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. 

How can PANAVIA SA Cement Universal achieve high bond strength without primer treatment?

"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.

What are the differences among the shades?

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.

Are the shades the same than the previous version, PANAVIATM SA Cement Plus?

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

How many times can the product be used?

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

Handmix: 60 cases (crown)

How long is operation time/setting time?

  • 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

Is the long chain silane coupling agent, LCSi (Long Chain monomer, a new technology?

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.

Can PANAVIA™ V5 tooth primer be used for tooth surface treatment?

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

Is there a difference in performance between the handmix and the automix type?

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.

How should the product be stored?

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

What are the causes of quick curing?

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.

What are the reasons for the prosthetic restoration falling off, when removing excess cement?

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.

When preparing the abutment tooth after core build-up, the restoration falls off.

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.

What are the leading factors of prosthetic restoration failure?

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.

Why doesn’t PANAVIA™ SA Cement Universal cure properly on the table?

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.

How to check the product to see if it can be properly cured?

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).

How long is the final cure?

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.

Which cement application is recommended: prosthetic side or abutment side?

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).

Can the product be used for cementing metal (PFM)?

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

Can the product be used for fiber post cementations?

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.
