During trial fitting your restoration might become contaminated with proteins reducing the 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 4.5 which allows usage not only extra-orally but also intra-orally. It is the easy way to optimise your bondings including cementation procedures.
