During trial fitting your restoration might become contaminated with proteins which then reduce the final bond strength. Katana™ Cleaner has a high cleaning effect due to the surface-active characteristic of MDP Salt. In contrast to other cleaners, Katana Cleaner has a pH value of 4.51 which allows usage not only extra-orally but also intra-orally. It is an easy way to optimize your bondings including cementation procedures.

Indications for Use
  • Cleaning of contaminated glass-ceramic, zirconia, resin/metal restorations and fibre posts.
  • Cleaning of (contaminated) prepared tooth structure (cavity, root canal and tooth abutment), and implant abutment.

Easy & Fast

Unlike other cleaners that require longer rubbing time, Katana Cleaner only requires 10 seconds.

  1. Apply and rub Katana Cleaner for at least 10 seconds.

High Cleaning Effect

After the intra-oral try-in of restorations, saliva and/or blood reduce the bond strength. Katana Cleaner's high effectiveness in cleaning recovers the original bonding strength. Now you are really prepared to cement your restoration!

Cleaning Effect on Zirconia

Contamination with artificial saliva

Contamination assessment is based on the degree of staining with a stain that binds to proteins present in saliva.


Contamination with blood (human plasma)

The degree of contamination is evaluated by the degree of staining with an agent that binds to (albumin, fibrinogen, immunoglobulin) proteins present in human plasma.

Clean up contamination with MDP technology and improve bond strength when you use Katana Cleaner. Katana Cleaner is a universal cleaner with MDP salt and a pH of 4.5 for intra- and extra-oral applications.

Katana Cleaner - Bottle Refill (Item Number: 605489): 4 mL bottle

Q: Why is it possible to use Katana Cleaner intra-orally?

A: Due to its mild pH value of 4.5, Katana Cleaner can be used not only extra-orally but also intra-orally, making it an all-purpose universal cleaner for both - tooth structure and prosthetics.

Q: What is the cleaning mechanism (action mechanism) of Katana Cleaner?

A: Katana Cleaner contains MDP Salt formed from the phosphate ester monomer, MDP and Triethanolamine. When applied to the tooth or prosthetic restoration surface, the hydrophobic group of MDP salt adheres to contamination, MDP salt weakens the surface tension of contamination and breaks it up. MDP salt surrounds contamination, floats from the surface of tooth and prosthetic restoration. Further breakdown occurs while in suspension and all that’s left to do is to rinse with water and dry.

Q: What is the chemical difference between strong alkaline and strong acids to remove contamination?

A: Katana Cleaner removes proteins and other contaminants by the surface-active effect of MDP Salt. Due to the alkalinity, proteins and other contaminants are decomposed and removed, but there is a high risk of invasiveness to the human body and it is limited to use extra-orally. The strong acid decomposes and removes contaminants such as proteins, but it causes decalcification of the tooth surface, which may reduce the bond strength of the adhesive material used.

Q: Does the dye remain on the surface to be cleaned?

A: No. Katana Cleaner is a detergent and thus highly washable. That’s why it is expected that there will be no dye remaining.

Q: Is rubbing required?

A: Yes. Surfactant chemically lifts contaminants, but rubbing is necessary to remove them physically from the surface.

Q: Is it possible to rub for less than 10 seconds?

A: No. By rubbing for 10 seconds, a sufficient decontamination effect is achieved.

Q: Is it a substitute for Ivoclean? What is the difference? Is there a difference between the two?

A: Yes and it even has an extra benefit - Katana Cleaner can be used intra-orally too. Ivoclean, on the other hand, can be used only extra-orally due to its strong alkalinity.

Q: Can it be used with cements and bonds from other manufacturers?

A: Yes. Please follow the Instructions For Use provided by the manufacturer of the cement or bonding agent.

Q: On what prosthetics can Katana Cleaner be used?

A: It can be used for a wide range of dental restorations such as glass-ceramic, zirconia, resin and metal restorations and fibre post.

Q: Does Katana Cleaner have an etching effect on the prosthetic surface to give mechanical retention?

A: Katana Cleaner does not have an etching effect on prosthetics. Depending on the type of prosthetics material, it is necessary to make use of the recommended surface roughening treatment (f.e. hydrofluoric acid or sandblasting).

Q: Does Katana Cleaner work as a silane?

A: No. Use a silane such as Clearfil™ Ceramic Primer Plus Silane Coupling Agent additionally, if necessary.

Q: How should Katana Cleaner be stored?

A: Store at 2-25°C. Keep away from direct sunlight.

Q: What is the shelf life?

A: 36 months from the date of manufacture.

Q: How quickly should Katana Cleaner be used after dispensing?

A: Use within 10 minutes after dispensing in a mixing dish.

Q: Why are bubbles present in the liquid during dispensing?

A: Bubbles may appear in the dispensed liquid due to the surface-active effect of the MDP Salt, which will not affect the product´s desired cleaning performance effect. Do not shake the bottle before use. When the bottle is shaken, bubbles may form and liquid may ooze out from the nozzle.
