2023 DENTAL ADVISOR Top Product is an everyday cement that eliminates the need for a separate primer

PANAVIA™ SA Cement Universal adheres to virtually all substrates, including lithium disilicate, in a single procedure without the need for a separate primer or silane, and it also offers easy, gingival-friendly removal of excess cement and requires no refrigeration. Therefore it is no wonder that this year DENTAL ADVISOR gave PANAVIA™ SA Cement Universal Top Product award in the category of Indirect Restoratives.

What makes its strong and durable bond possible without the added step of applying a separate substrate is that PANAVIA™ SA Cement Universal combines two innovative technologies in a single product. The silane coupling agent, LCSi monomer, establishes a durable, chemical bond with porcelain, lithium disilicate, and composite resin; and the original MDP monomer provides for chemical reactiveness with zirconia, dentin and enamel.

The result is a convenient, versatile, and efficacious single solution to practitioners’ everyday cementation needs for a wide variety of indications, including cementation of crowns/bridges, inlays/onlays, posts, splints, and even adhesion bridges.

The significant benefits and quality of PANAVIA™ SA Cement Universal are reflected in the study findings and feedback of the 31 DENTAL ADVISOR clinical evaluators who used the cement in 516 applications and gave it an overall clinical rating of 96 percent. Their comments on its ease of use, handling characteristics, and aesthetics included: “Good flow and film thickness;” “Amazing viscosity, tack cure-ability, and very easy cleanup;” and “Great color match, and I liked the universal ability to work with so many substrates.”

The Top Product or Preferred Product Awards conferred by US-based DENTAL ADVISOR were introduced to help busy practitioners make sense of the numerous new solutions indicated for less invasive techniques, standardized or simplified procedures, and better outcomes on a regular basis. DENTAL ADVISOR conducts its practice-based clinical evaluations and product performance tests shortly after product launch, and publishes results annually online to help potential users identify high-quality new dental materials and determine which among them are best suited to fulfill their individual requirements.

Five-time DENTAL ADVISOR Top Product delivers more than a reliable bond

For the fifth time CLEARFIL™ SE Protect has made DENTAL ADVISOR’S list of Top Products for 2023, placing it among dental materials and equipment deemed to deliver the best practice-based performance based on the publication’s annual review of such products.

Featured in the Bonding Agent Self-etch category, CLEARFIL™ SE Protect is a self-etch adhesive that offers more than just a reliable bond. It is:

• Antibacterial (self-etch) primer thanks to containing MDPB monomer
• Built on the same system of the gold standard adhesive CLEARFIL™ SE BOND
• Possible to use it for extended indications of core build-up and indirect restoration with CLEARIFL™ DC Activator.

All in all - surely a great addon to your dental toolbox.

Application of CLEARFIL SE Protect is also truly versatile – you can use it for any direct restorations, but in particular when treating hypersensitive teeth. It is also widely used for core build-up with self- or dual-cured resin materials and for cementation with composite resin cement in combination with CLEARFIL™ DC Activator.

CLEARFIL™ SE Protect offers you following features:

• Virtually no post-operative sensitivity
• Excellent bond strength for enamel and dentin
• Fast and simple procedure with low technique sensitivity

These attributes are reflected in the study findings and comments of the 13 DENTAL ADVISOR editors and consultants—seven of whom had previously used CLEARFIL™ SE BOND in their practices. After CLEARFIL™ SE Protect was assessed over a six-week period during which over 150 restorations were placed, it received a 98% clinical rating by consultants using a 1-5 rating scale,

The practitioners evaluating the product found no post-operative sensitivity. Among their observations mentioned in the online DENTAL ADVISOR report were the fact that the primer and bond wet the tooth evenly. They also mentioned that CLEARFIL™ SE BOND is effective in the reduction of sensitivity when placed on areas of recession or similar areas of sensitive tooth structure.

DENTAL ADVISOR Top Product to address everyday dental challenges

For the 8^th straight year, CLEARFIL MAJESTY™ ES Flow has been included among DENTAL ADVISOR’S Top Products, which is made up of dental materials and equipment deemed to deliver the best practice-based performance based on the publication’s annual review of such products.

Featured in the Direct Restorative category, CLEARFIL MAJESTY™ ES Flow comes in three different levels of flowability designed to cover a range of flowable composite indications that cannot be addressed with a single viscosity. Whether the practitioner needs the product to be firm enough to stay put where applied, malleable enough to create a specific shape, or runny enough to flow into every corner or undercut, one of the three versions is appropriate for the job. For example, the high flowability variant is the perfect choice for cavity linings and as a resin coat in immediate dentin sealing (IDS) procedures, while the super low flowability option is suitable for direct veneer procedures and for build-up of posterior cusps etc.

Equipped with Kuraray Noritake Dental Inc.’s Light Diffusion Technology, the universal flowable composite integrates seamlessly with the surrounding tooth structure. If no recontouring required, then a glossy surface can be obtained simply by wiping with a cotton roll soaked in alcohol.

The version tested by the 29 DENTAL ADVISOR consultants in more than 900 applications in their dental practices was the medium flowability variant (Low) of CLEARFIL MAJESTY™ ES Flow. They evaluated properties including placement/handling, aesthetics, viscosity, and polishability and rated all to be “excellent,” with no running during placement and a good adaptation to the cavity walls and when flowed into narrow areas. This led to a recommendation rate of 100 percent and a 98 percent overall clinical rating.

Among their comments were: “The material blended so well with the tooth structure that you had to look hard to find the interface;” “Syringe design prevents oozing from the tip;” and “Readily apparent on radiographs.”

The Top Product or Preferred Product Awards conferred by US-based DENTAL ADVISOR were introduced to help busy practitioners make sense of the numerous new solutions indicated for less invasive techniques, standardized or simplified procedures, and better outcomes on a regular basis. DENTAL ADVISOR conducts its practice-based clinical evaluations and product performance tests shortly after product launch. It publishes results annually online in its January/February issue to help potential users identify high-quality new dental materials and determine which among them are best suited to fulfill their individual requirements.

Shortly before KATANA™ Zirconia ML was launched at the IDS in Cologne ten years ago, I had the pleasure to be invited to Japan. We visited the KATANA™ Zirconia production facilities and learned from Kazunobu Yamada and Takuro Nagura how the new material worked. So far, all dental zirconia I had used was white and quite opaque.

I was immediately impressed by the complexity of the production procedure including all the measures taken by Kuraray Noritake Dental to provide for an extremely high material and blank quality. The blanks appeared to have an extremely homogeneous multi-layered structure and a high density responsible for stable edges and smooth surfaces. What we were told in the manufacturing plant was confirmed by Kazunobu Yamada, who shared his experience and showed us several full-contour cases. I was pleasantly surprised by the fact that he was able to produce impressive outcomes without adding any colour. Moreover, Kazunobu Yamada was obviously able to polish the surface of his restorations within seconds. The perfectly smooth surface would allow us avoid the use of glaze, which usually wears off very quickly, leaving a potentially rough surface that may harm the antagonist.

Based on what I had learned in Japan, I went back to Italy and started experimenting with the amazing new material. While Kazunobu Yamada had identified KATANA™ Zirconia ML as the solution for monolithic restorations in the posterior area, I started using it in every region of the mouth – with different design concepts from full-contour to micro-cutback with micro-layering in the vestibular area. The occlusal contact area was always held in plain, polished zirconia.

Fig. 1. Early example of anterior restorations made of KATANA™ Zirconia ML individualized with CERABIEN™ ZR using the new micro-layering technique.

Fig. 2. Possible cutback design.

During the testing period, I learned a lot about the new zirconia, which was so different from earlier generations. The most important insight was that that the processing conditions have a huge impact on the final outcome. Kuraray Noritake Dental provided valuable support e.g. in the form of sintering protocols and processing and finishing recommendations. This helped me develop my own workflow and concept based on a full-contour design in the posterior and different micro-cutback options with micro-layering in the anterior region. For me, this is a perfect combination of the new type of zirconia (KATANA) and the traditional porcelain material (CERABIEN™ ZR Luster Porcelain and Internal Stain).

In May 2013, at a meeting of the Noritake Study Club in Florence, Italy, I presented the new approach for the first time. Many colleagues were enthusiastic about it and started adopting it. While further developments like more translucent (cubic) material variants and a new generation multi-layered zirconia with a flexural strength and translucency gradient increased the application options and aesthetic potential, micro-layering became a truly popular approach used by dental technicians all over the world. In 2016, it was recognized as a relevat workflow during a closed meeting of the European Academy of Aesthetic Dentistry.

Fig. 4. More recent case showing a patient who received restorations made of KATANA™ Zirconia STML …

Fig. 5. … finished with CERABIEN™ ZR Internal Stains and a micro-layer of CERABIEN™ Luster Porcelain LT1.

But what is the major reason for the success of the concept and of multi-layered zirconia with KATANA™ Zirconia ML as the pioneer? In my opinion, it should not be implemented for greater simplicity or economic reasons, as one might assume at first thought. The time saved in the layering procedure should be spent on other tasks such as surface texturing and a fine-tuning of the processing procedure. The real benefit is that KATANA™ Zirconia ML and its successors allow for better solutions adapted to the patient’s needs. First of all, they enable us to save natural tooth structure, as the required wall thickness is reduced. They also offer mechanical advantages, as chipping is avoided, and the occlusal contact area remains smooth over time. In my dental laboratory, we changed our workflows completely and – preferring a more conservative approach whenever indicated for the case on hand – we often abandon full layering.

KATANA™ Zirconia can be considered as a great contribution to the digital workflow in the dental laboratory and office, which increases the efficiency of prosthodontic procedures. With the KATANA™ Zirconia Multi-Layered series, it is easy to hold our promise of delivering the best possible quality and aesthetics. The reason is that the materials support us in an ideal way, delivering the perfect combination of tradition and innovation.

Case by Michal Jaczewski

This patient came to the clinic to improve the aesthetics of her smile. After an aesthetic and functional analysis, it was decided to align and restore the teeth using a minimally invasive protocol with flowable composite.

INITIAL SITUATION

Fig. 1. The patient had worn teeth, visible abrasion, erosion and crowding in the lower arch.

Fig. 2. Situation after orthodontic treatment, full arch ready to restore.

Fig. 3. A silicon mould is used for the Flowable Injection Technique to restore the teeth with flowable composite. The silicone injection mould had injection channels prepared and was placed to check for proper fit.

Fig. 4. For this case it was decided to use CLEARFIL MAJESTY™ ES Flow Low in shade XW.

Fig. 5. Teflon tape was used, in order to separate the teeth.

Fig. 6. The restoration is completely additive; the teeth are not prepared at all. Total etching of the enamel is the best pre-treatment in this situation. K-Etchant Syringe (35% phosphoric acid) was applied for 10 seconds.

Fig. 7. A surgical suction tip was used in order to carefully remove the phosphoric acid gel and protect the isolations on the teeth. Followed by rinsing off completely with water in the usual manner.

Fig. 8. Each tooth was gently air dried for 10 seconds. CLEARFIL™ Universal Bond Quick was applied with a rubbing motion without additional waiting time. Followed by drying of the entire bonding treated surfaces by blowing mild air for more than 5 seconds until the bonding no longer moves.

Interview with Yoshihisa Yamada
General Manager, Technology Division of Kuraray Noritake Dental Inc.

KATANA™ Zirconia ML was introduced ten years ago, at the IDS 2013 in Cologne, as the dental industry’s first zirconia product with a multi-layered colour structure. Since that event, KATANA™ Zirconia ML blanks have become very popular. Continued development efforts have led to the current line-up of multi-layered materials, KATANA™ Zirconia UTML, STML and HTML PLUS, and our latest product – KATANA™ Zirconia YML. Our new technology with colour, translucency and strength gradation is found in KATANA™ Zirconia YML.

How important was the invention of the Kuraray Noritake Dental’s original multi-layered technology for the dental market?

Our impression is that the material has had a significant impact on the dental market. Being the first zirconia material with a multi-layered colour structure, KATANA™ Zirconia ML was our first product of its class to offer the properties needed for the efficient production of full-contour zirconia restorations with a natural look. Before its introduction, the “full-contour zirconia” concept had not been widely accepted due to the aesthetic properties of the zirconia materials available so far: Many of them lacked the desired level of translucency, while others needed to be treated with dyeing liquids or stains in a complex procedure to obtain a natural shade appearance. With the launch of multi-layered zirconia blanks, which successfully added natural colour gradation to the structure, aesthetic full-contour zirconia restorations started to become popular among dental technicians worldwide. The high potential of the technology was confirmed at the IDS 2013 show, when we saw not only end-users, but also engineers from competing companies come to look at this product.

What changes were driven forward by the introduction of KATANA™ Zirconia ML?

After the introduction of KATANA™ Zirconia ML, many companies started developing multi-layered zirconia discs, creating a new dental product category with an added technical and clinical value. We are convinced that the invention of Kuraray Noritake Dental has played a major role in the shift from zirconia exclusively used as a framework material to alternative approaches including full-contour zirconia restorations. If only monochromatic zirconia discs had been available, we imagine that an increased number of dental technicians would have embraced the concept of using liquid colourants to achieve a natural appearance of full-contour crowns and bridges. That would have prevented monolithic zirconia restorations from becoming as popular as they are today.

How did the KATANA™ Zirconia ML technology evolve over the past ten years?

Based on our unique core technology developed for inventing KATANA™ Zirconia ML, we have been continuing making efforts to create even better products. One of Kuraray Noritake Dental’s great strengths is its ability to develop all the raw materials for its zirconia products inhouse. This makes it possible for us to adjust the boundaries between the layers as inconspicuously as possible, even when discs consist of multiple layers. This enabled us to provide multi-layered discs with the required strength and aesthetic qualities, and with a stable, predictable shrinkage rate. In the past ten years, we have focused on adding new materials with different levels of translucency and strength to offer a portfolio that meets the demands of virtually every dental technician, practitioner and patient.

For example, the advent of KATANA™ Zirconia STML, which has even better aesthetic qualities than KATANA™ Zirconia ML, has made it possible to use it all by itself to create highly aesthetic restorations, with no need to characterize or individualize the restorations. Of course, if you use KATANA™ Zirconia Multi-Layered discs and treat the restorations with a surface staining agent, such as CERABIEN™ ZR FC Paste Stain, you can create even more aesthetic restorations in a shorter time.

What are the benefits of Kuraray Noritake Dental’s multi-layered technology, as compared with other manufacturer’s solutions?

KATANA™ Zirconia multi-layered discs offer the advantage of delivering the proper colour even when they are sintered at high speed. There are two reasons for this. First, we developed unique raw materials with suitable characteristics for high-speed firing. This allows the creation of restorations with the same strength, stability, and aesthetics to be achieved after both short- and long-time firing. The second reason is that we possess the technical know-how concerning excellent shading that Noritake Dental Supply, one of Kuraray Noritake Dental’s predecessors, cultivated during its many years spent developing ceramic materials. Noritake Co., Ltd., parent company of Noritake Dental Supply, is a long-established ceramic manufacturer that is famous for its tableware and other outstanding products. It is this background that allows us to properly control pigment coloration using our inorganic pigment know-how and to provide unique firing schedules. These two strengths enable us to bring unique advantages to our products. That is, they remain stable and retain appropriate colouration even under rapid firing schedules.

How did you manage to shorten the sintering times so significantly, resulting in your speedy sintering with uniform protocols?

When shorter sintering times became possible, Kuraray Noritake Dental recommended that KATANA™ Zirconia ML be sintered for seven hours. After that, when a new furnace claiming being capable of short-time firing was launched, we used it to fire KATANA™ Zirconia ML on a trial basis. We found, happily, that our zirconia material was uniquely compatible with rapid firing. This was the beginning of our full-fledged study of short-time firing of our zirconia material. You could say that we began investigating short-time firing almost by accident. Then, while developing KATANA™ Zirconia STML and KATANA™ Zirconia UTML, successors of KATANA™ Zirconia ML, we focused on incorporating short-time firing into their features and made various adjustments, finally achieving the optimal combination of factors for the successful short-time firing of zirconia.

What are the benefits of Kuraray Noritake Dental’s second-generation multi-layered technology, as compared with other manufacturer’s solutions?

One advantage of KATANA™ Zirconia YML is that it can be applied to treat a wider range of cases without complex limitations on position within the disc. The reason: it delivers this high level of aesthetics while still maintaining great strength. This advantage of being appropriate for a wider range of cases also simplifies inventory management. In addition, users benefit from our expertise in developing raw materials and reproducing colour with ceramics. This expertise enabled us to develop a zirconia product in which each layer has a different level of translucency, while great strength and admirable aesthetics are maintained throughout the whole blank.

The sintering recommendation is only a guideline; some adjustments may be required depending on each individual furnace. If the furnace cannot be set according to the 54- or 90-minute sintering schedule, speed sintering cannot be used.

* The restorations may be removed at 800°C or less depending on the circumstances.
** For the sintering schedule of KATANA™ Zirconia HT, please refer to the Handy Chart in product packaging.

Is it really possible to address every case using only KATANA™ Zirconia YML?

For every case that can be treated either with KATANA™ Zirconia STML, KATANA™ Zirconia UTML, or KATANA™ Zirconia HTML PLUS, KATANA™ Zirconia YML is also an option. Hence, it is possible to use only KATANA™ Zirconia YML for all your zirconia cases – which is probably one of the reasons for its great popularity. It features both great strength and excellent aesthetics, and – being so versatile – it helps simplify inventory management. Of course, Kuraray Noritake Dental’s other multi-layered materials feature outstanding properties as well. Depending on the features you need, it would also be an option to select from these products - KATANA™ Zirconia STML, KATANA™ Zirconia UTML, or KATANA™ Zirconia HTML PLUS – to realize your ideal restorations.

Why is the KATANA™ brand in general so popular among dental technicians around the world?

We think that dental technicians choose KATANA™ because they find that they can create highly aesthetic restorations using simple, straightforward steps.

Is there any further development potential in multi-layered technology?

On the basis of our technical know-how, there is always room for improvement. That is why we never stop innovating and listening to the voice of our customers. Developing what supports them in improving their outcomes while providing for more predictable, less stressful procedures is our ultimate goal. Right now, we expect to develop products with even greater strength, increased translucency, and outstanding aesthetics that will have a natural look resembling real teeth, even when the material used is full-contour zirconia.

Case by Kokla Thalia, Postgraduate student in Restorative Dentistry program, Faculty of Dentistry, National and Kapodistrian University of Athens, Greece

Restoring Class II cavities can be challenging due to limited access to the posterior area, where the interproximal contact needs to re-established in a proper way. Inadequate contacts tend to result in increased plaque accumulation, food impaction and, as a consequence, the development of caries and irritation of the interproximal gingiva. Therefore, it is essential that the interproximal contact is restored based on the model of nature. A suitable matrix system and a proper clinical protocol can help us succeed in this context. The following clinical case is used to illustrate a possible strategy.

Fig. 1. Initial clinical situation. 23-year-old female patient with caries on the mandibular left second premolar.

Fig. 2. Situation after cavity preparation, isolation of the working field with rubber dam and the placement of a sectional matrix fixed with a ring. It is essential that the matrix imitates the natural shape of the contact area, which is usually rather flat or concave cervically and convex in the middle and occlusal parts.

Fig. 3. Etching of the tooth structure with phosphoric acid etchant. Afterwards, the adhesive needs to be applied (in this case, Universal Bond Quick was used according to the manufacturer’s instructions).

Fig. 4. CLEARFIL MAJESTY™ ES-2 Premium in the shade A3E is applied in the distal box to build up the wall first. In this way, the available space is used to model the most critical part of the restoration before simply filling the cavity in increments with the dentin shade A3D.

FINAL SITUATION

Fig. 5. Final restoration after finishing and polishing. In accordance with the concept behind CLEARFIL MAJESTY™ ES-2 Premium with its pre-defined shade combinations, the final enamel layer was build-up using the shade A3E. However, the use of a single opacity is also possible in the posterior region depending on the aesthetic demands.

CONCLUSION

By elevating deep interproximal margins, it is possible to focus on the critical designing of the contact point when there is still sufficient space available to do so. This simplifies the procedure, while all that is left to do can be managed in a straightforward way like a Class I restoration.

“Hver eneste dag får jeg bekreftet at Kuraray Noritake står for høyeste kvalitet”

Fabian Giaevers seneste karrieregrep gjør ham glad for hver nye arbeidsdag. For ham, er det tre  faktorer som gjør at jobben hans som den første Business Development Manager for Kuraray Noritake i Norge, skiller seg ut. For det første: det faktum at Kuraray Noritake selger fremragende produkter. For det andre: selskapskulturen som han betegner som ‘ekstraordinær’. Og til sist arbeidsoppgavene i selve jobben, som er varierte og utfordrende. “Alt sammen er morsomt og spennende.”

Kuraray Noritake er allerede et velkjent varemerke i Norge, men frem til nå har alle markedsføringsaktiviteter foregått via depotene. I september tok Fabian Giaever fatt på sin oppgave  med å lære opp norske kunder i alt som har med produktene å gjøre.

Fra sine tidligere stillinger i  Unident og Align hadde han allerede opparbeidet seg solid kunnskap om dentalbransjen. Her ble han også oppmerksom på det gode ryktet som produktene fra Kuraray Noritake  har. “Jeg visste at Kuraray Noritake var helt I toppsjiktet. Det som er enda bedre, er at dette blir bekreftet av dem jeg møter.” Fabian vet nå at ikke bare har produktene et godt rykte, men de viser også gode kliniske resultater . “ CLEARFIL SE Bond for eksempel, har 13 år med kliniske studier bak seg . Den har  96% overlevelse etter 13 år. Det er helt unikt.”

Alt-mulig-mann

Fabian er også veldig fornøyd med bedriftskulturen. “Det er uvanlig. Folk er så vennlige og hjelpsomme . Det føles som et lag, nesten som en familie. Selv om vi anstrenger oss for å oppnå gode resultater,  alltid prøver å forbedre oss, knuse mål osv.,er det alltid med et positivt tankesett og en følelse av samhold. Intensjonene er gode og bidrar til å skape en atmosfære hvor folk føler seg trygge og selvsikre. Det faktum at alle virkelig bryr seg og ønsker å hjelpe, skaper mye energi.”

Fabian arbeider fra sitt hjem i Tønsberg. Majoriteten av kundene kommer fra hans område: Oslo og omegn, men han reiser ofte rundt til møter. Dette passer ham perfekt, han liker det faktum at ingen dager er like. Enten det er en sementerings-workshop på en tannklinikk, å diskutere sintringsprotokoller med et tannteknisk laboratorium eller å diskutere markedsføringsaktiviteter med en forhandler, «Jeg er litt av en alt-mulig-mann og jeg liker den allsidigheten og den variasjonen som slike dager gir meg .”

Mer fornøyde pasienter

Når han blir spurt om sine ambisjoner for den nye jobben, har Fabian en tydelig  visjon. “Jeg vet at vi har de beste produktene. Jeg vil forsikre meg om at jeg, med hjelp av mine kollegaer, kan få det norske markedet til å bli like glad i produktene våre som vi er. Enhver tannlege ønsker det beste for pasientene sine. Jeg vil være sikker på at jeg gjør dem oppmerksomme på hvor unike produktene våre er. Til syvende og sist er jeg overbevist om at dette vil resultere i mer fornøyde pasienter .”

Fabians 7 år gamle datter bor hos ham halvparten av tiden. Hun betyr veldig mye for ham.Han liker også å trene, gå på rulleski og være med venner. Når det gjelder arbeidet, tror Fabian at han er en ganske ambisiøs person . “ Jeg ønsker å kunne bidra med å spre kunnskap om de fantastiske produktene våre, men for meg er det også viktig å glede meg til jobben, og å være entusiastisk over å starte arbeidsdagen. Hos Kuraray Noritake,er dette absolutt tilfelle.”
