HATTERSHEIM AM MAIN, Germany: The KATANA Zirconia Multi Layered series from Kuraray Noritake Dental is popular among dental technicians and dentists around the world, as it offers great mechanical and optical properties. These materials have different levels of translucency and strength, and their multilayered structure facilitates the creation of lifelike restorations. Furthermore, they are highly processable, which results in high milling accuracy and smooth margins. Together, these properties are extremely valuable for every dental office since they result in precise, durable and aesthetic restorations that help to exceed patients’ expectations.

Clinical long-term success of these zirconia restorations, however, is not determined by material choice and laboratory processing alone. The way clinical procedures such as cementation and intra-oral adjustments are carried out have a decisive impact. To achieve 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 the dental practitioner’s life easier and his or her 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 is compromised. As it is impossible to keep these surfaces free of oral fluids at the try-in stage, effective cleaning strategies are necessary. In tests comparing different methods and cleaning agents, sandblasting and the use of KATANA Cleaner have been shown to be highly successful in removing the proteins from the bonding surfaces.1

Unlike other zirconia cleaners that are often strongly alkaline, the KATANA Cleaner is biocompatible and suitable for intra- and extra-oral use. Hence, it is the perfect solution for cleaning KATANA Zirconia restorations as well as prepared enamel and dentine before cementation. The product has a high cleaning effect and is easy to use. It is simply rubbed in for 10 seconds, rinsed and dried.

Obtain a reliable bond using fewer components

Fewer components and fewer procedural steps—this is what an increasing number of dental practitioners look for when it comes to cementing zirconia restorations. For these practitioners, PANAVIA SA Cement Universal is the solution.

This self-adhesive resin cement contains the LCSi monomer, a proprietary long carbon chain silane coupling agent 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 famous MDP monomer is also present in the paste and allows for chemical reactivity with zirconia, dentine and enamel. Therefore, the product is appropriate 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 with other cements. This was already the case for product’s predecessor PANAVIA SA Cement Plus, as demonstrated by research from Tufts University in Boston in the US.2 For particularly demanding cases, the bond strength of PANAVIA SA Cement Universal to tooth structure can be increased with the aid of CLEARFIL Universal Bond Quick.

Choose the proven and familiar multistep system

For those who prefer to stick with their trusted multistep procedures, PANAVIA V5 is the go-to product. It is suitable for all restorations and is the strongest cement Kuraray Noritake Dental has ever developed. Having five shades, it is also the most aesthetic option, allowing dental practitioners to cement all tooth-coloured restorations with confidence. PANAVIA V5 is designed to work ideally with KATANA Zirconia and is indicated for cementing a wide range of indirect restorations as well as for post-and-core procedures and amalgam bonding.

Create antagonist-friendly surfaces

Studies have shown that the surface roughness of a restoration has a larger impact on antagonist wear than the hardness of the dental material. This means that for antagonist-friendly behaviour, 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 innovative shape of its flexible polishing spirals offers various benefits and 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. Since they can be sterilised, the spirals may also be reused.

A winning team for reliable results

By using restorative materials, cleaning solutions, cementation systems and polishing spirals from Kuraray Noritake Dental, dental practitioners will benefit from streamlined procedures and reliable results. The products are not only designed to work with one another but are also thoroughly tried and tested for combined use so that procedures can be carried out with the utmost confidence.
