Reizēm ir nepieciešams plūstošs materiāls, kas iekļūst katrā stūrī un rievā, bet citreiz ir labāk, ka materiāls paliek uzlikšanas vietā un ir veidojams, lai iegūtu nepieciešamo formu. Ja ir pieejama tikai viena viskozitātes pakāpe, ir grūti ar to izlīdzēties katrā klīniskajā situācijā, kurā ir indikācija plūstošā kompozītmateriāla izmantošanai. Tāpēc Kuraray Noritake Dental Inc. piedāvā CLEARFIL MAJESTY™ ES Flow ar trim dažādām plūstamības pakāpēm: High, Low un Super Low. Plūstamības līmenis tiek izvēlēts atkarībā no klīniskās situācijas, kā arī kavitātes ģeometrijas un lieluma. Piemēram, augstas plūstamības materiāls ir vispiemērotākais, lai to izmantotu kā kavitātes aizsargslāni, bet īpaši zemās plūstamības materiāls ir ieteicams darbā ar kompozītmateriālu venīriem.

Tomēr šis materiāls sniedz vēl daudz vairāk iespēju, par ko pārliecinājās „Dental Advisor“ konsultanti, jau sesto reizi pēc kārtas piešķirot šim produktam „Editors’ Choice“ uzlīmi un balvu „Top Product Award“ (38. izdevums, 01. numurs, 2021. gada janvāris–februāris).

29 „Dental Advisor“ konsultanti savās zobārstniecības prakses vietās pārbaudīja CLEARFIL MAJESTY™ ES Flow vidējās plūstamības variantu (Low). Viņi izvērtēja produkta sniegumu attiecībā uz ievietošanu/darbu ar to, estētiku, viskozitāti un pulējamību. Par visām četrām īpašībām produkts saņēma vērtējumu „izcili“. CLEARFIL MAJESTY™ ES Flow Low netek ievietošanas laikā, nodrošina labu pielāgošanos kavitātes sieniņām, kā arī vienmērīgu plūsmu šaurākās vietās. Uzņēmuma Kuraray Noritake Dental Inc. gaismas difūzijas tehnoloģija nodrošina, ka materiāls nemanāmi integrējas apkārtējā zobu struktūrā, un spīdīgu virsmu var iegūt, vienkārši noslaukot to ar spirtā samitrinātu kokvilnas vatīti.

Pateicoties šīm īpašībām un pārliecinošam vispārējam sniegumam, produkta saņemtais vērtējums ir 98%, un visi 29 konsultanti apliecināja, ka viņi ieteiktu CLEARFIL MAJESTY™ ES Flow saviem kolēģiem. Kopš 2015. gada produkts atkārtoti ir saņēmis balvu „Top Product Award“; tas ir pieejams ar trim dažādām viskozitātēm, tāpēc visdrīzāk tas kļūs par produktu, ko izvēlas vēl plašākam klīnisko indikāciju lokam.

The Function that becomes aesthetics

Italian dental technician, CDT Stefano Lograno, demonstrates how it is possible for the medical-technical prosthetic team to adopt a protocol from diagnostics to cementation, in which aesthetics can be functionally guided in a simple, predictable and standardized workflow following the criteria of the gnathological school of Vienna of Prof. Rudolf Slavicek.

BOND | VOLUME 7 | 10/2020

With so many different adhesives, cements, and restorative materials available on the dental market, it seems difficult to decide which products are best suited to fulfill the individual requirements. A direct comparison obtained through testing of all products in the dental office is simply impossible due to the great number of available solutions. Laboratory investigations provide information about specific product properties, but usually cannot create the overall picture. Moreover, the results of different tests are barely comparable due to variations in test conditions. Clinical study results are very useful as they shed light on clinical (long-term) performance of selected materials, but they are usually published years after a product’s launch. Hence, they are not available in the early stages. A great source of information are practice-based evaluations, as they support potential users in identifying high-quality dental materials.

One of the institutions conducting and publishing practice-based clinical evaluations and product performance tests is the US-based DENTAL ADVISOR. Once per year, the dental materials and equipment with the best performance receive a Top Product or Preferred Product Award. The list of winners is published online (www.dentaladvisor.com) and in the January-February issue of the DENTAL ADVISOR. In 2021, numerous products from Kuraray Noritake Dental Inc. were among the award winners.

Top Product Awards

CLEARFIL™ SE Protect received a Top Product Award in the category Direct Restoratives, Bonding Agent: Self-Etch. The self-etch adhesive is based on the formulation of the gold standard two-step self-etch adhesive CLEARFIL™ SE BOND but contains an extra MDPB monomer offering an antibacterial cavity-cleansing effect and fluoride for long-term fluoride release. The honoring of the DENTAL ADVISOR is based on a material test carried out by 13 DENTAL ADVISOR consultants and editors in their dental offices for six weeks. Due to its excellent performance, the antibacterial self-etch adhesive received a 98 percent clinical rating.

For the sixth year in a row, the Top Product Award in the category Direct Restoratives, Composite: Highly Filled Flowable went to CLEARFIL MAJESTY™ ES Flow.

The universal flowable composite that also became the Editor’s Choice comes in three different levels of flowability, from high to super low*. This enables the user to choose the right viscosity for every clinical situation – with the high flowability variant being the perfect choice for cavity lining and as a resin coat in IDS procedures, and the super low flowability option being specifically suited for direct veneer procedures and even for build-up of posterior cusps etc. The universal flowable composite was tested by 29 consultants of the DENTAL ADVISOR in more than 900 clinical applications. The evaluated properties – placement/handling, aesthetics, viscosity and polishability – were rated “excellent”. This led to a recommendation rate of 100 percent and a 98 percent overall clinical rating.

^{*DENTAL ADVISOR evaluated only the standard level of flowability (Low), because other two variants are not available in US.}

A product that earned recognition from the Dental Advisor for the seventh time already is TEETHMATE™ DESENSITIZER for hypersensitivity treatment.

The product that won a Top Product Award this year was designed to create hydroxyapatite (HAp), which is able to occlude open dentinal tubules and enamel cracks. This leads to a significant reduction of hypersensitivities when applied to exposed, mechanically treated or freshly prepared dentin. When used in the context of restorative treatment, TEETHMATE™ DESENSITIZER does not have a negative effect on the bond strength of dental adhesives or cements. A six-month clinical evaluation conducted by the DENTAL ADVISOR involving 27 patients with gingival recession-related hypersensitivity revealed that the use of the product is very effective in providing immediate and even long-term (six-months) hypersensitivity relief. This resulted in an excellent rating with a score of 96 percent.

In the category Self-Adhesive Cement, an additional Top Product Award went to PANAVIA™ SA Cement Plus. The dual-cure self-adhesive resin cement stands out due to its ease of use, favorable viscosity and an easy excess removal feature after tack-curing.

Preferred Products

Among the 2021 Preferred Products that also received an Editor’s Choice label is PANAVIA™ SA Cement Universal. The Top Product Award winning self-adhesive universal resin cement from 2020 contains the unique LCSi monomer. This monomer is a silane coupling agent, which has a unique long carbon chain in its molecule. This carbon chain establishes a durable, chemical bond with porcelain, lithium disilicate and composite resin without the need for a separate silane containing primer. The other key technology present in the formulation is the original MDP monomer, which ensures chemical reactiveness with zirconia, dentin and enamel. Together, the technologies ensure that PANAVIA™ SA Cement Universal produces a strong and durable bond with virtually every restorative material without the need for a separate primer. Its handling characteristics, aesthetics and gingival friendliness received very good to excellent ratings from 31 clinical evaluators, who used the cement in 516 applications. The result of the overall clinical rating was 96 percent.

Moreover, CLEARFIL™ Universal Bond Quick was honored as a Preferred Product by the Dental Advisor consultants for the second consecutive year.

The universal bonding agent may be applied using the self-etch technique or – together with K-ETCHANT syringe – in the selective enamel etch or total-etch technique. Containing our rapid bond technology – a combination of the original MDP monomer with innovative hydrophilic amide monomers – the adhesive works instantly and without the need for extended exposure times, application of multiple layers or extensive rubbing into the tooth structure. The fast and easy application procedure was one of the main reasons for the consultants of the DENTAL ADVISOR to select CLEARFIL™ Universal Bond Quick as a Preferred Product and Editor’s Choice with a 98 percent score in a clinical evaluation.

Finally, CLEARFIL™ CERAMIC PRIMER PLUS became a Preferred Product in 2019, 2020 and 2021, and an Editor’s Choice in 2021. It contains the original MDP monomer and a silane monomer, which ensure excellent bond strength to all kinds of restorative materials, i.e., to silica-based ceramics, zirconia, composites and even metals. Users benefit from procedural simplicity as the product is just applied and dried to the bonding surface after the recommended pretreatment. In a clinical evaluation, the product received a recommendation rate of 96 percent and a 96 percent overall score from the DENTAL ADVISOR consultants.

Conclusion

Most of the Kuraray Noritake Dental products that received an award this year are based on resin technologies, one of our key competencies. In the 1980s, we developed the original MDP monomer, a functional monomer, which is an essential component of any adhesive product we introduced down to the present day, including the award-winning CLEARFIL™ SE Protect, PANAVIA™ SA Cement Universal, CLEARFIL™ Universal Bond Quick and CLEARFIL™ CERAMIC PRIMER PLUS. This is only one of our many areas of expertise. We also provide users with preventive products and a whole range of restorative materials – from composite filling materials like CLEARFIL MAJESTY™ ES Flow to dental ceramics like KATANA™ Zirconia UTML, STML and HTML. We see the winning of the awards as a positive proof of a reliable product performance that supports dental practitioners in reaching their own goals.

Interview with Dr Imad Ghandour

In recent years, zirconia has emerged as the preferred choice for dentists who wish to perform restorative procedures with a reliable and metal-free material. With the recent development of multi-layered aesthetic high-translucency options, zirconia’s popularity has further increased. In comparison to the opaque whiteness of older generations of zirconia, these newer versions have an enhanced appearance and functionality that makes them suitable for natural-looking anterior restorations.

Kuraray Noritake Dental’s KATANA Zirconia disc range is made with a proprietary zirconia powder - processed in-house - that gives it its natural appearance. Suitable for zirconia prostheses, from single crown to full arch, it is an ideal option for restorations in both the anterior and posterior regions. We spoke with Dr Imad Ghandour, a prosthodontist with a strong scientific background and a private practice in Le Cannet in France, about his experiences with the KATANA Zirconia range in restorative procedures.

Dr Ghandour, when did you first start using zirconia as a material for your restorations?

In 1998, when I was still sintering manually, I began using zirconia alumina. It was nice to have an alternative to metal alloys that was much more aesthetic. From 2003, however, I started with VITA blocks, but only for frameworks - I would still build up with ceramics. Now, with so much of dentistry being digitally focused, there is a need for a material that can be milled without changing anything in the morphology of the teeth. Why? Because we need to be able to reproduce the treatment plan as accurately as possible. Simply put, the KATANA Zirconia range solves this need for me.

With respect to dentistry being digitally focused, how has this changed the role of the dentist regarding performing restorative procedures?

Well, it is clear that we have entered the age of digital dentistry. Around 80 per cent of restorations are conducted via CAD/CAM systems and without dentists even touching the materials themselves. There are great advances being made in the technologies that are available for everyday use in dental practices worldwide, and many of them can be used to assist dentists performing restorative procedures. It is important, though, to keep in mind that these technological advancements alone will not lead to better results - they should supplement the requisite hands-on skills and techniques that all dentists must first learn. With this base of fundamentals, we can then use digital dentistry to make restorative procedures more predictable and reproducible. Of course, to ensure the best results in restorative procedures, dentists also need to use the materials that have the best aesthetic and mechanical properties.

For how long have you been using Kuraray Noritake Dental’s KATANA Zirconia range, and what has your experience been?

I have been using KATANA Zirconia for a little bit more than one year. In that time, I have primarily used the KATANA Zirconia STML (Super Translucent Multi Layered) line and have been pleasantly surprised by how natural-looking the restorations I have made with the material are. For example, when I sinter a crown made of Katana Zirconia STML, I am amazed at how much the sintered material is reminiscent of a pearl - it truly brings to mind the idea of one’s teeth being one’s pearly whites.

When using KATANA, how do you ensure that you select the correct shade to achieve a natural look?

Firstly, no one - not a dentist nor a dental technician - can be absolutely certain that the shade and chroma of the restoration that is in one’s hand will be the same once it is in position in the oral cavity. This is due to the complexities of the oral environment - the pinkness of the gingivae, for one, can have a large impact on how the restoration appears, often making it seem far duller than it does in the light of a dental laboratory. This can cause dental practitioners to compensate and make prostheses that appear far brighter than they will when they are in place.

With a product like KATANA and its related glazing materials, however, I can create crowns and other restorations that have an optimal fluorescence and translucency and are able to maintain their shading better than any other ceramic material I have used. I am able to select a shade with the confidence that it will look exactly the same once placed inside the mouth, with its chroma remaining unabsorbed by the gingiva. Achieving a natural look, then, depends on choosing a shade that is as close to that of the surrounding dentition as possible. Since KATANA Zirconia UTML (Ultra Translucent Multi Layered) is available in 16 standard shades and a further four enamel shades, there is no shortage of options in this regard.

How does the multi-layered technology of KATANA Zirconia help you to achieve optimal and natural-looking aesthetic results?

Well, firstly, the layering of the material is designed to replicate the colour and translucency progression of natural teeth, which allows for restorations to blend in as much as possible. This multi-layered technology has also proved itself to be very handy when I am sintering crowns made of KATANA Zirconia. Simply put, if one sinters a crown quickly, it will be a little more opaque. If one sinters it at a higher temperature and quite slowly, it will be much more translucent. The multi-layered aspect of KATANA Zirconia is excellent in that it gives me the ability to make restorations more or less translucent depending on what is required.

With 40 years of success in the commercial dental products market, Kuraray Noritake Dental has firmly established its commitment to providing leading-edge solutions for adhesive dentistry. The 1983 introduction of the PANAVIA™ EX resin cement, which utilized Kuraray’s original MDP monomer technology, set the industry standard for adhesion and has continued to do so for over 30 years since. With PANAVIA™ V5, and PANAVIA™ SA Cement Universal which is the latest addition to PANAVIA™ family, Kuraray Noritake Dental presents a pair of resin cements designed for strong, durable bonding for zirconia-based and other restorations.

PANAVIA™ V5

PANAVIA™ V5 is a resin cement with exceptional procedural simplicity and predictability. It sets a new standard for adhesion to the KATANA™ Zirconia Block or other zirconia, allowing for self-cure dentine bond strengths equal to our gold-standard light-cure bonding agent, CLEARFIL™ SE BOND. PANAVIA™ V5 offers natural aesthetic stability in shading through its amine-free paste, which is available in five shades and has been scientifically proven to demonstrate a lower level of post-curing colour variance than other cements.

PANAVIA™ SA Cement Universal

PANAVIA™ SA Cement Universal is a forerunner in self-adhesive resin cements that adheres virtually to all materials including glass ceramics. The original silane coupling agent, LCSi monomer, incorporated in the paste creates a strong chemical bond to porcelain, lithium disilicate and composite resin. Available in an automix or handmix option, its high concentration of MDP monomer allows for increased chemical reactiveness with zirconia, which, combined with mechanical retention created by sandblasting, has been demonstrated as crucial for durable bonding to this material. Building upon the success of our PANAVIA™ SA Cement Plus, it offers a wide range of indications for adhesion and is suitable for crowns/bridges, inlays/onlays, posts, and even adhesion bridges.

By Peter Schouten, Technical Manager Kuraray Europe Benelux

Kuraray Noritake’s self-adhesive cement series, PANAVIA™ SA Cement Universal, has evolved through several stages of development since it was first introduced as “CLEARFIL™ SA Cement”. Over time, various improvements have been implemented, bringing us to our latest product: PANAVIA™ SA Cement Universal. Improvements include: strengthening of the bonding power to dental tissue, increasing the storage temperature to room temperature and extending the shelf life to three years. What remained the same - the easy removal of any excess cement, the moisture tolerance and the integration of the original MDP monomer.

The original MDP enables PANAVIA™ SA Cement Universal to be bonded to dental tissue as well as to metals and zirconia ceramics. Until recently, the chemical bonding of glass-based materials such as porcelain, glass ceramics, including lithium disilicate, and composite, was only possible with an additional silane-based primer.

With the introduction of PANAVIA™ SA Cement Universal the silanisation step has become redundant. Instead, the silane has been incorporated into the PANAVIA™ SA Cement Universal paste. As a result, there is only one single universal procedure, without the need for separate primers.

LCSi

Adding silane to the paste sounds easy. However, there are some limiting factors. For example, keeping silane in the form of γ-MPS (γ-methacryloxypropyltrimethoxysilane) active for a long time is a challenge. This is partly due to γ-MPS’ hydrophilic nature. Contact with water under acidic condition results in hydrolysis of alkoxy groups of silane. Therefore, it is best to use a more hydrophobic and thus stable silane and to avoid bringing it into contact with water and acid prematurely.

We have been using a long-chain silane (LCSi) for some time in a number of our superior composites, such as CLEARFIL™ MAJESTY™ Posterior and CLEARFIL™ MAJESTY™ ES Flow. However it’s the first time we have used it in a cement.

This unique silane has long hydrocarbon spacer (the hydrocarbon chain between the silanol group and the methacrylate group) which makes it more hydrophobic and stable than the small γ-MPS molecule. The reaction with the silica particles in the glass-based materials is expected to be also more orderly and faster. The result is a more optimally bonded surface with a greater resistance to hydrolysis.

A great deal of thought has gone into combatting the degradation of silanes in PANAVIA™ SA Cement Universal. It was decided to separate the more hydrophilic components from the hydrophobic ones so they only come together when the paste is mixed. This is why we are able to achieve a three-year shelf life, even when stored at room temperature.

Research

It’s not only in-house data that show comparable or even better bonding of PANAVIA™ SA Cement Universal to glass-based materials, than with its previous version, PANAVIA™ SA Cement Plus, in combination with CLEARFIL™ CERAMIC PRIMER PLUS. The first results from independent research are also strongly supporting this.

With PANAVIA™ SA Cement Universal, there is now a self-adhesive resin cement on the market that allows virtually all indirect materials to be bonded directly without the intervention of primers or bonding.

CLEARFIL MAJESTY™ ES-2 is the composite that allows intuitive creation of natural-looking restorations. The combination of its self-adaptive capacity, thanks to the use of light diffusion technology, its natural fluorescence, high filler content, fine workability and exceptional polishability provide outstanding aesthetic results.

CLEARFIL MAJESTY™ ES-2 is a forgiving composite. It blends seamlessly with the adjacent tooth structure. This is because CLEARFIL MAJESTY™ ES-2 incorporates light diffusing technology. This makes it possible to cover the entire VITA range using only VITA A shades.

In our endeavors to reproduce nature, we need to step away from the notion that artificial materials do all the work for us. Especially enamel is a difficult kind of tissue to replace with artificial materials like composite. When you replace natural enamel with translucent composite you almost never reach the desired goal! Why is this? The most determinant factor is the difference in value. Natural enamel increases in value in proportion to its thickness, while for (translucent) composite the value decreases.

In certain situations, for instance for the reproduction of the incisal edge of a central incisor, where a translucent zone is naturally present, the use of a more or less translucent composite is needed. However, it is often the opacity of a composite that we wish to harness in order to cover up underlying (irregular) discoloration. To do this, the use of a translucent composite is clearly not desirable. In this situation, the most opaque variant is your first choice of composite.

You've probably been there: applying anatomical layering techniques with a composite system, only to arrive at a somewhat disappointing result that looks too gray. This can be explained by the fact that, as a manufacturer - and we're certainly not alone here - we have created some confusion by giving composites names such as Dentin and, worse still, Enamel. These names suggest that these materials can be used as a replacement for natural dental tissue. Due to the totally different optical properties of each dental tissue and composite, this can only be achieved within a frequently too narrow spectrum. Therefore, when it comes to the use of the more translucent composite variants, I recommend a cautious approach. Only use such variants where transparency is required.

...it is often the opacity of a composite that we wish to harness in order to cover up underlying (irregular) discoloration. To do this, the use of a translucent composite is clearly not desirable. In this situation, the most opaque variant is your first choice of composite.

Kuraray Noritake Dental offers three basic opacities within the CLEARFIL MAJESTY™ family. These three variants enable you to create transparency where necessary, or indeed to avoid it in zones where greater coverage is required. The most opaque variant within the CLEARFIL MAJESTY™ ES-2 family is Premium Dentin. The semi-opaque variant Classic and the semi-translucent variant Premium Enamel.

The challenging class IV restoration as an example. The tendency exists to use dentin composite up to the dentin-enamel junction. Don't do this, but instead apply it right up to the outermost edge of the restoration. This means also covering the beveled enamel. Depending on the desired end result, you should only use the more translucent variants, Classic or Premium Enamel, in the incisal third.

Working with different variants of CLEARFIL MAJESTY™ ES-2 in one restoration where more than one variant end at the surface the transition from one type to the other is totally seamless. Since all three variants have virtually the same high filler percentages and filler type. During finishing you won't even notice the transition between the different variants. The polishability of all the variants is also identical.

All these qualities make CLEARFIL MAJESTY™ ES-2 your aesthetic composite for the effortless creation of natural-looking restorations. Both anterior and posterior.

In this interview, Dr Adham Elsayed, certified specialist in dental prosthodontics and implants and clinical and scientific manager at Kuraray Noritake Dental, details the benefits of the company’s new CLEARFIL MAJESTY™ ES-2 Universal composite and explains its application in the daily dental workflow.

Though dentists are becoming increasingly specialised, there’s a growing demand for products that can be used for all indications. How does CLEARFIL MAJESTY™ ES-2 Universal fit this model?

First, we need to explain the meaning of the term ‘universal’ in this context. Previously, there have been two types of composites that differ according to the area of application: anterior composites, used in Class III, IV and V restorations where the aesthetic outcome is the priority, and posterior composites, in which the mechanical properties like strength and wear rate are more important. Universal composites, then, are those that can be used for all types of restorations in the anterior as well as the posterior region.

Another way in which ‘universal’ can be considered is in relation to shade. In this case, the term is used to describe a restorative composite system that exists in fewer shades, one that can adapt to the tooth structure independent of the colour of the tooth. A major benefit of this type of composites is that it offers a simplified workflow.

CLEARFIL MAJESTY™ ES-2 Universal is essentially universal in both meanings: it is one system that can be used for posterior and anterior restorations, and it is also provided in only three shades—one for posterior, and two for anterior.

Universal products, whether they are luting cements, bonding agents or composites, are attractive to dentists as long as they offer simplification of the treatment procedure without compromising quality and durability.

How does CLEARFIL MAJESTY™ ES-2 Universal build upon the success of the CLEARFIL MAJESTY™ range?

The CLEARFIL MAJESTY™ family is very well established at this stage. It includes such products as CLEARFIL MAJESTY™ Posterior, one of the most popular posterior composites owing to its superior mechanical properties and minimal polymerisation shrinkage. CLEARFIL MAJESTY™ ES-2 is an extensive system that is highly beneficial thanks to its outstanding optical properties and ability to produce high-end aesthetics in the anterior region using Kuraray Noritake Dental’s multilayering technique. The three flowable alternatives of CLEARFIL MAJESTY™ ES Flow, with different consistencies, are also other successful members of the family.

Kuraray Noritake Dental now continues the success story of CLEARFIL MAJESTY™ with the latest innovative product that can change the definition of the universal composite. CLEARFIL MAJESTY™ ES-2 Universal incorporates several attributes from the well-established ES-2 and ES Flow, including Kuraray Noritake Dental’s light diffusion technology (LDT).

Speaking of LDT—how does this technology benefit the composite?

LDT allows the material to scatter and reflect light rays at many different angles, which, in turn, allows the composite restoration to diffuse light in a similar way to the surrounding tooth structure. Hence, it eliminates aesthetic problems like the visibility of restoration and preparation borders. Thanks to innovative LDT, optimal particle fillers and opacity, CLEARFIL MAJESTY™ ES-2 Universal blends seamlessly with the surrounding tooth structure and emulates natural teeth, eliminating the need for shade selection.

As you mentioned, CLEARFIL MAJESTY™ ES-2 Universal comes with one shade for posterior restorations and two for anterior restorations. Can such a reduced shade range still truly deliver aesthetic restorations?

CLEARFIL MAJESTY™ ES-2 Universal is not the first composite on the market with a reduced shade system. However, we can safely say that it is the first to focus on aesthetics and not just on reducing the number of shades.

We know from experience that using one-shade composite systems in the anterior region mostly leads to unsatisfying aesthetic results, even with the use of an opaquer composite to reduce shade-matching interference. This is due to the fact that trying to provide one shade for all posterior and anterior restorations, and for all tooth shades, compromises the aesthetic to a high extent. In other words, using a highly translucent material to try to match all restorations and shades will result in the interference of other objects in the mouth, such as the tongue, gingivae and so on.

Kuraray Noritake understood this fact well and solved the problem by introducing three shades with translucencies designed to match specific indications. It is important to note the simplicity of the workflow, since only one syringe per restoration is required. This makes CLEARFIL Majesty™ ES-2 Universal a true game-changer, as it provides the perfect match between simplicity and aesthetics.

What other advantages does this new composite deliver?

Other advantages include the superior mechanical properties for which the CLEARFIL MAJESTY™ family is already known, such as favourable wear properties, low shrinkage stress and high strength. It can be polished easily and retains its gloss. Moreover, the handling of the material is a huge advantage: this includes a long working time of about 270 seconds under ambient light. It is non-sticky and can be sculpted easily.

Which dental professionals would benefit most from this product?

The perfect match between simplicity and aesthetics offers the clinician several benefits. It delivers a very straightforward time-saving procedure without compromising aesthetic results. There is no need for exact shade selection, thereby excluding visible errors of non-matching shades, and there is also a reduced amount of material stock needed. Therefore, in my opinion, this should be the product of choice for most cases in everyday practice.

Advances and developments in dental materials are rapidly accelerating, and clinicians should integrate these innovations and make their daily practice more efficient with simplified workflows, time-saving procedures, fewer material selections and, accordingly, less technique sensitivity and less need for dental practice personnel to become acquainted with an abundance of materials.

No shade taking needed. Just one shade to cover all posterior cases. Even the larger Class I's and II's!

Anterior cases from B1 to C4 done with only two shades, without the need for shade taking. Can you imagine? No additional opake materials (light blockers) needed too.
