The KATANA™ Zirconia Multi-Layered series from Kuraray Noritake Dental Inc. (Kuraray Noritake Dental) is popular among dental technicians and dentists around the world, as it offers great mechanical and optical properties. The available materials have different levels of translucency and strength, and a multi-layered structure that facilitates the creation of lifelike restorations.
Furthermore, they are very well processable, which results in a high milling accuracy and smooth margins. Together, these properties are highly valuable for every dental office, as they result in precisely fitting, durable and beautiful restorations that help you exceed your patients’ expectations.
Clinical long-term success of these zirconia restorations, however, is not only determined by the material choice and laboratory processing alone. The way clinical procedures such as cementation and intra-oral adjustments are carried out have a decisive impact as well. In order to support you in your striving for a long-lasting bond between the tooth and the restoration, and to facilitate intra-oral polishing, Kuraray Noritake Dental has developed a wide variety of in-office products designed to make your life easier and your practice even more successful.
Remove bond-strength compromising proteins
When proteins present in blood and saliva are deposited on the bonding surfaces of teeth or dental restorations, the bonding performance of dental adhesives and self-adhesive resin cements will be compromised. As it is impossible to keep these surfaces free of oral fluids at try-in, effective cleaning strategies are required. In tests comparing different methods and cleaning agents, sandblasting and the use of KATANA™ Cleaner have been highly successful in removing the proteins from the bonding surfaces1.
As KATANA™ Cleaner is a biocompatible material (unlike other often strongly alkaline zirconia cleaners), it is suitable for intra- and extra-oral use. Hence, it is the perfect solution for cleaning your KATANA™ Zirconia restorations as well as prepared enamel and dentin before cementation. The product has a high cleaning effect and is easy to use: simply rub it in for ten seconds, rinse and dry.
Obtain a reliable bond with fewer components
Fewer components and fewer procedure steps, this is what an increasing number of dental practitioners strives for when it comes to cementing zirconia restorations. For all of them, PANAVIA™ SA Cement Universal is the solution.
The self-adhesive resin cement contains the proprietary long carbon-chain silane coupling agent (LCSi Monomer) developed by Kuraray Noritake Dental that delivers a strong, durable chemical bond to porcelain, lithium disilicate and composite resin without the need for a separate primer. The original MDP monomer, also present in the paste, allows for chemical reactiveness with zirconia, dentin and enamel.
Therefore, the product is indicated for a wide range of indications (including adhesion bridges) without the need for separate priming and bonding. Another important fact is that excess removal requires a significantly lower force compared to other cements. This was already the case for product’s predecessor PANAVIA™ SA Cement Plus, as reported by a researcher from Tufts University in Boston, Massachusetts2. For specifically demanding cases, you may increase the bond strength of PANAVIA™ SA Cement Universal to tooth structure with the aid of CLEARFIL™ Universal Bond Quick.
Choose the proven and familiar multi-step system
For all those who would like to stick to multi-step procedures they have trusted for years, PANAVIA™ V5 is the go-to product. It is suitable for all restorations, including those that demand the highest possible bond strength. It is the strongest cement Kuraray Noritake Dental ever developed, and with five shades, it is the most aesthetic one, too. This allows you to cement all tooth-coloured restorations with confidence, no matter whether they have a retentive or non-retentive design. PANAVIA™ V5 is designed to work perfectly with KATANA™ Zirconia, and is indicated for cementing a wide range of indirect restorations, and also for post-and-core procedures and amalgam bonding.
Create antagonist-friendly surfaces
Studies have shown that surface roughness of a restoration has a larger impact on the wear of the antagonist than the hardness of the dental material. This means that for an antagonist-friendly behaviour, the restoration surfaces need to be perfectly polished. This task is easily accomplished with TWIST™ DIA for Zirconia, which may be used after intra-oral adjustments or in the context of maintenance measures.
The flexible polishing spirals with an innovative shape offer you various application benefits for excellent polishing results. TWIST™ DIA for Zirconia is highly suitable for occlusal surface polishing as the shape and contour of the zirconia restoration is maintained. As they are sterilizable, the spirals may be reused.
A winning team for reliable results
By using a restorative material, cleaning solution, cementation system and polishing spirals from Kuraray Noritake Dental, you will benefit from streamlined procedures and reliable results. The products are not only designed to work with each other, but also thoroughly tried and tested for combined use, so that you can carry out your procedures with utmost confidence.
