NOW 18 Minutes Sintering using the CEREC SpeedFire
KATANA™ Zirconia Block, the innovative multi-layered zirconia block*1, can be used with Dentsply Sirona's CEREC system*2. Now the 18 minutes sintering program*3 is developed and installed into CEREC SpeedFire. New sintering technology makes it possible to fabricate full zirconia restoration in approx. 35 minutes.
*1 CL shade is not a multi layered block. *2 For using this product, CEREC software 4.5.2 or later is required, and for 18 minutes sintering, software 4.6 or later is required. *3 In case that wall thickness is less than 3mm using dry milling. *4 Dry milling is recommended.
If wet milling/grinding is performed by using cooling water contaminated by silica-based glass ceramics (lithium disilicate glass, etc.), the translucency of the zirconia may be reduced after baking. Before wet milling/grinding, clean the milling/grinding chamber, cooling water tank and filter insert. The cooling water must be changed in order to assure optimum results.
An ideal composite material should satisfy three basic requirements: function, aesthetics and biocompatibility. A member of the CLEARFIL MAJESTY family, Kuraray Noritake Dental’s CLEARFIL MAJESTY™ ES Flow combines excellent handling, polishability and mechanical strength to provide a solution for all cavity classes. This universal flowable composite employs silane and filler technologies to maximise both its procedural and aesthetic outcomes, allowing dentists to create long-lasting restorations with reduced chairside time.
A new standard for flowable composites
Traditionally, a composite’s flowability has been inversely related to its filler content. When flowable composites were first introduced in the mid-1990s, their lower viscosity was enabled by a filler level much lower than that of conventional composites. This, however, meant that these flowables fared poorly in a clinical setting, demonstrating inferior mechanical properties when compared to traditional hybrid composites.
With CLEARFIL MAJESTY™ ES Flow, dentists can now use a flowable composite with mechanical properties comparable to those of conventional alternatives. Thanks to Kuraray Noritake Dental’s silane technology, millions of submicron filler particles fit into the composite, reliably adhering to the resin and maintaining long-term stability. CLEARFIL MAJESTY™ ES Flow possesses a scientifically tested flexural strength of over 150 MPa, similar to that of a universal nano hybrid composite, making it suitable for use in Class I and II restorations.
Aesthetic restorations
However, the small, durable particles of CLEARFIL MAJESTY™ ES Flow provide more than just mechanical reliability. Special cluster fillers provide a light diffusion effect that is similar to that of natural teeth, meaning that the material blends effortlessly with the existing tooth structure. Unlike other flowables, CLEARFIL MAJESTY™ ES Flow is glossy immediately after curing. This gloss can be improved with remarkable simplicity—simply wipe the cured resin with an ethanol-moistened gauze or cotton roll to produce a smooth surface that is proven to maintain its gloss over time.
Ideal handling
CLEARFIL MAJESTY™ ES Flow’s low viscosity monomers ensure that it has excellent handling characteristics, promising better sculpting for the dentist. The flowable composite does not stick to the needle tip or to any instruments, only adhering to the area to which it is applied, while the proprietary design of the syringe itself minimises air bubbles when dispensing. Once dispensed, the paste possesses great consistency with its non-slumping formula, ensuring that it can maintain its shape. A truly universal composite, CLEARFIL MAJESTY™ ES Flow allows dentists to create highly aesthetic restorations with ease.
Obtain results in four simple steps
Creating aesthetic and durable restorations has never been more achievable. Simply prepare the cavity and apply bonding, dispense and sculpt the CLEARFIL MAJESTY™ ES Flow, light-cure and, finally, polish. It’s as easy as that.
Paul de Kok, Authorized Restoritive Dentist(KvPA), teaches Indirect restoritive dentistry(ACTA) , Researcher at Materials Science department (ACTA), demonstrates in this instructional video how excellent lasting aesthetic results are achieved by using PANAVIA™ V5.
Scientific research has demonstrated that, when bonding zirconia, optimal bond values can only be achieved with resin cements—specifically, MDP monomer-based resin cements. With PANAVIA V5, we offer a dual-cure resin cement with dentine bond strengths equal to our gold standard light-cure bonding agent CLEARFIL SE BOND, even when used in self-cure mode. Through our KATANA Zirconia range, Kuraray Noritake Dental presents a ceramic material for restorative procedures that has excellent translucency and shade options. Together, PANAVIA V5 and KATANA Zirconia make an ideal team for durable and reliable indirect restorations.
PANAVIA V5
In 1983, Kuraray introduced its patented MDP monomer in PANAVIA EX cement. With its clinically proven adhesion, our PANAVIA family has set the industry standard for adhesion for over 30 years. As the newest addition to the PANAVIA cement line, PANAVIA V5 provides strong bonding not just to zirconia but to hydroxyapatite and metals as well. Unlike other dual-cure resin cements, PANAVIA V5 offers improved bond strength to all tooth structures. Simple to use and with predictable results, PANAVIA V5 is unique in its user friendliness and procedural consistency.
KATANA Zirconia
Our KATANA Zirconia discs are processed using a proprietary zirconia powder, allowing it to have as natural a translucency and colour as possible. The KATANA range consists of several options designed for full-contour zirconia prostheses, from single crown to full arch: KATANA Zirconia UTML (Ultra Translucent Multi Layered), STML (Super Translucent Multi Layered), ML (Multi Layered) and HT (High Translucent). The multilayered build-up of KATANA Zirconia STML provides a translucency and chroma that gradually decrease from the cervical to incisal regions, just like natural dentition. KATANA Zirconia UTML is perfect for anterior restorations, such as veneers, owing to its natural translucency and colour gradient. With a flexural strength considerably higher than that of lithium disilicate, KATANA Zirconia has the mechanical and aesthetic properties to achieve well-balanced restorations between natural teeth in the anterior zone.
An ideal team
PANAVIA V5 provides a strong and durable bond between KATANA Zirconia-based restorations and the tooth structure. PANAVIA V5 resin cement offers optimal margins and predictable restorations. Always use PANAVIA V5 Tooth Primer for the pretreatment of the tooth and CLEARFIL CERAMIC PRIMER PLUS for the priming of the restoration.
“We’re thrilled by the possibilities presented from the combination of PANAVIA V5 and KATANA Zirconia,” said Mitsuru Takei, Head of Technical Services at Kuraray Europe. “Together, they make achieving natural-looking restorations easier than ever.”
TEETHMATE DESENSITIZER: A natural solution for sensitive teeth
Kuraray Noritake Dental’s TEETHMATE DESENSITIZER is designed to provide an immediate and long-lasting solution for dentine sensitivity. Owing to a specially modified powder free of potential irritants like methacrylates and colophony resins, TEETHMATE DESENSITIZER is biocompatible and harmless to tissue. The first desensitiser to form hydroxyapatite, TEETHMATE DESENSITIZER possesses a neutral taste that will please patients. Since its introduction in 2013, dentists have hailed the product for its safe tubule sealing and for providing patients with immediate relief.
TEETHMATE DESENSITIZER consists of a powder, composed mainly of calcium phosphate, and a liquid, whose chief component is water. The powder and liquid simply need to be mixed. After the paste has been applied with a superfine brush to the affected area for 30 seconds, the material sets into hydroxyapatite, providing an instant reduction of hypersensitivity by sealing the dentinal tubules and microcracks in the enamel.
Hydroxyapatite: The human body’s strongest mineral
The presence of hydroxyapatite encourages tooth remineralisation, protecting teeth against hypersensitivity and after professional tooth cleaning. TEETHMATE DESENSITIZER is composed of two different calcium phosphates that react under water to form hydroxyapatite. Since Kuraray Noritake Dental’s technology ensures the right calcium–phosphate ion ratio with a suitable pH level, the newly formed hydroxyapatite acts as if it were the patient’s own, crystallising so that it can neatly seal dentinal tubules and enamel cracks.
Suitable for most sensitivity issues
TEETHMATE DESENSITIZER has a wide range of indications, from whitening-related dentine sensitivity to the treatment of dentine exposed by periodontitis, abraded by harsh toothbrushing, or prepared for fillings and/or restorations.
TEETHMATE DESENSITIZER is an invisible and durable form of treatment. When applied, it occludes open dentinal tubules without leaving a film on the tooth. It is fast and easy to use—simply mix the powder and liquid, apply with a rubbing motion to the sensitive region for 30 seconds and rinse lightly with water. No air blowing or light curing is required, as the calcium phosphates in the substance harden on their own, providing patients with fast relief from sensitivity-related pain.
Proven effectiveness
In a survey conducted by Kuraray Noritake Dental, Japanese dentists were asked to rate the effectiveness of TEETHMATE DESENSITIZER. Of the 285 respondents, 92 per cent said that they were satisfied with the product’s effectiveness.
No impact on bond strength
TEETHMATE DESENSITIZER has been clinically proven not to reduce the bond strength of adhesives or cements when it is used prior to their application. This is a considerable advantage for dentists using etch and rinse adhesives, for instance, as they can apply TEETHMATE DESENSITIZER without any concerns about potentially deleterious effects on restorations. A smart, invisible and durable form of dentine sensitivity treatment, TEETHMATE DESENSITIZER promises to satisfy both dentists and patients.
Founded in 1926, Kuraray has a long and storied history of providing high-quality solutions in a number of fields. Since 1978, we have produced dental materials, such as the CLEARFIL and PANAVIA families of products, that have given our company a deserved reputation as an industry leader in excellence and innovation. However, there are many more products manufactured by Kuraray Noritake Dental that play a pivotal role in the daily work of dental practices worldwide, albeit without the same level of name recognition. With that in mind, we would like to highlight just a few of them.
CARIES DETECTOR
Kuraray Noritake Dental’s CARIES DETECTOR is the ideal tool for practitioners of conservative dentistry. A caries-disclosing agent, it assists in identifying carious lesions and plays a pivotal role in the maintenance and preservation of teeth. Fast and easy to use, CARIES DETECTOR provides support in the excavation of the demineralised and caries-affected outer tooth layers by staining the damaged parts red. This ensures that as little as possible healthy dentine is removed, aiding in the preservation of the tooth structure and maintaining pulp vitality. Dentists can excavate with precision and confidence thanks to our CARIES DETECTOR.
K-ETCHANT Syringe
The K-ETCHANT Syringe comes with an etching gel that is indicated for etching tooth enamel and dentine, as well as cleaning the surface of ceramics, hybrid ceramics, composite resins and metal restorations. Being thixotropic, it can be applied in a controlled manner and stays where you want it. Thanks to this nifty property, the K-ETCHANT Syringe treats only those areas that need to be etched.
CLEARFIL™ CERAMIC PRIMER PLUS
A stable, universal primer for all cement and repair indications, CLEARFIL™ CERAMIC PRIMER PLUS incorporates both Kuraray Noritake Dental’s original MDP monomer and a silane monomer. This allows for excellent bond strength to all silica-based ceramics, zirconia, composites and even metals, all at a high level of procedural simplicity. CLEARFIL™ CERAMIC PRIMER PLUS pairs perfectly with the adhesive resin cement PANAVIA™ V5 for reliable restorations.
Of course, this is only a glimpse into the variety of solutions that Kuraray Noritake Dental delivers. To find out more about our wide range of dental products, visit https://www.kuraraynoritake.eu/en/.
In 1978, Kuraray shook up the dental market with the introduction of CLEARFIL BOND SYSTEM F, the world’s first total-etch adhesive system. Having inaugurated the era of adhesive dentistry, we steadily introduced new dental products over the following years. In 1983, Kuraray introduced the PANAVIA EX resin cement. By utilising our patented MDP monomer technology developed in-house, PANAVIA EX enabled Kuraray to set the industry standard for adhesion—a position we have held in the decades since. This year marks the 40th anniversary of Kuraray’s entry into the commercial dental products market, providing a perfect opportunity to reflect on how far we have come since.
Kuraray—Rooted from a true trailblazer Founded in June 1926 by Magosaburo Ohara in Kurashiki in Japan, Kuraray has transcended our humble origins as a producer of rayon to become a leading global manufacturer of medical products, materials, textiles, chemicals, resins and much more. Our commitment to research and development in the fields of chemistry and engineering has led to many market firsts and a reputation as a pioneer of new products and technologies.
A history of innovation From the very beginning, Kuraray has been focused on the manufacture of high value-added products. At the time of the business’s birth, rayon was a new type of synthetic material, and over the ensuing years, Kuraray was able to master its production. In 1950, we became the first company in the world to develop the technology to mass-produce POVAL (polyvinyl alcohol), paving the way for the production of the new synthetic fibre Vinylon in the same year. CLARINO, a water-resistant synthetic leather substitute for shoes, bags and other items, was released in 1964 after extensive research and testing, and quickly collected international awards for its technology.
Kuraray’s continued emphasis on independently developed proprietary technologies and techniques, rather than relying on imported alternatives, has enabled our company to provide original, high-quality products for a variety of different industries. High on this list is dentistry.
The Kuraray Noritake Dental era In April 2012, Kuraray Medical and Noritake Dental Supply merged to form Kuraray Noritake Dental. By bringing together the materials and technologies developed by each of these market-leading companies, Kuraray Noritake Dental has continued to deliver dental bonding agents, ceramics and other reliable products to over 90 countries worldwide. The KATANA Zirconia range, for example, employs our unique multi-layered zirconia technology to provide a ceramic restorative material with superior translucency and perfect blending properties, while rapid bond technology ensures that CLEARFIL Universal Bond Quick delivers a lasting bond faster and easier than ever.
Through a focus on research and production, Kuraray Noritake Dental is ideally positioned to continue providing leading-edge solutions to dental issues both now and in the future.
At Kuraray Noritake Dental, we understand that the most important factors for successful prostheses are strength and aesthetic appearance. With our KATANA Zirconia multi-layered series, we are proud to provide a range of materials with the translucency, colour gradient and durability to make every prosthesis as natural as possible, from veneers to full-contour restorations.
Launched in 2015, KATANA Zirconia UTML (Ultra Translucent Multi Layered) is the most translucent series at 43 per cent, a level equal to that of lithium disilicate or glass. This optimal translucency, combined with its natural colour gradient, allows the material to be used with confidence for veneers and crowns between natural teeth in the anterior region. KATANA Zirconia UTML is available in 20 shades in two shade groups (standard and enamel), with the reduced chroma of the enamel shades allowing for an enhancement of the translucency of the incisal area. As the flexural strength of KATANA Zirconia UTML—557 MPa—is 30 per cent higher than that of lithium disilicate, it can be reliably used to produce durable and aesthetic single restorations.
KATANA Zirconia STML (Super Translucent Multi Layered) likewise has a natural colour and translucency gradient that transmits light in the incisal area while blocking it in the cervical area. This provides clinicians with the basis for beautiful full-contour prostheses, regardless of the abutment colour. With a translucency of 38 per cent and a flexural strength of 748 MPa—even higher than that of UTML, this series is recommended for up to three-unit posterior bridges, as well as crowns in the anterior and posterior regions.
The KATANA Zirconia ML (Multi Layered) and HT (High Translucent) series possess a flexural strength of 1,125 MPa, providing the highest level of mechanical strength in the KATANA line. Ideal for frameworks and long-span bridges, this series has a translucency of 31 per cent and ensures the aesthetic appearance of zirconia required by Kuraray Noritake Dental.
Give your brush a break
Often, the only way to ensure a prosthesis’s natural appearance is by dipping. With the KATANA Zirconia series, prostheses simply need to be milled and sintered to create natural aesthetics. To give them an even more natural look, the buccal surface can be stained with FC Paste Stain (Cerabien ZR).
Cementation with PANAVIA
Built upon the foundation of our original MDP monomer, PANAVIA cements are the best option for cementing prostheses or bonding to zirconia in a dental practice or laboratory. Both PANAVIA V5, developed for all indications, and PANAVIA SA Cement Plus, designed for ease of use, utilise the MDP monomer and have high bond strength to zirconia and durability. With PANAVIA cements, restorations can be cemented adhesively, expanding the options for use with zirconia.
No other resin cement offers such ease of use and consistency in procedure. Indeed, the unrivalled simplicity and predictability of PANAVIA V5 is nothing less than astonishing.
Always the same cementation procedure. Always the special PANAVIA V5 Tooth Primer for the pretreatment of the tooth. And always CLEARFIL CERAMIC PRIMER PLUS to prime the restoration.
In 1983, Kuraray introduced the PANAVIA EX resin cement and, with it, our patented MDP adhesive monomer. Since then, the MDP monomer has repeatedly been clinically proved and has set the industry’s adhesive standard for over 30 years. PANAVIA V5 is the newest addition to the PANAVIA cement line and sets a new adhesive benchmark for resin cements by providing self-cure dentine bond strengths equal to our gold standard light-cure bonding agent CLEARFIL SE BOND.
PANAVIA V5 is able to provide strong bonding not just to hydroxyapatite but to metals and zirconia as well. It can be used for all clinical cementation indications, including on crowns, veneers, inlays/onlays, bridges, crowns/abutments on implants, and posts. With PANAVIA V5, you always follow the same procedures prior to prosthetic cementation: roughen and prime the prosthesis, prime the tooth, and apply the cement to the prosthesis.
Aesthetic stability in shading
When it comes to maintaining shade in aesthetic cementation, conventional composite cements tend to discolour over time. With PANAVIA V5, Kuraray Noritake Dental presents an amine-free paste in five different shades—Universal (A2), Clear, Brown (A4), White and Opaque (only in self-cure mode)—that has been scientifically proved to demonstrate a lower level of post-curing colour variance than amine-based cements do. In addition, the new PANAVIA V5 try-in paste allows you to accurately simulate the shading of your cementation before it has been performed. As part of Kuraray Noritake Dental’s continued commitment to excellence in adhesion, this combination aims to enable the continued stability and natural appearance of the cement shading after curing.
PANAVIA V5 Tooth Primer
Almost all dual-cure resin cements available have been scientifically demonstrated to require light curing to achieve an acceptable bond strength. Thanks to Kuraray Noritake Dental’s focus on research and development, the MDP monomer-based PANAVIA V5 Tooth Primer contains a new catalyst that solves this issue. It provides an accelerated curing process from the moment the cement touches the primer, which, in turn, leads to a high degree of conversion from monomer to polymer. PANAVIA V5 presents a milestone in adhesion, as it offers improved bond strength for all tooth structures, even when used in the self-cure mode.
Prime with CLEARFIL CERAMIC PRIMER PLUS
PANAVIA V5 is designed for use in conjunction with CLEARFIL CERAMIC PRIMER PLUS, a stable universal primer that contains both Kuraray Noritake Dental’s original MDP monomer and a silane monomer. This allows it to bond to all silica-based ceramics (including lithium disilicate), zirconia, composites and metals. It provides excellent bond strengths to all of these materials, as well as procedural simplicity.
Peter Schouten, Technical Manager at Kuraray Europe Benelux
Before universal adhesives were available, two major techniques were used: total-etching adhesives, which basically work with phosphoric acid etching on enamel and dentine; and self-etching adhesives, which can be used with or without the option of etching enamel selectively. Prior to the introduction of self-etching adhesives in the late 1990s, dentists used mostly total-etching techniques. While this procedure achieves strong enamel bonding, it can also be very technique-sensitive and involves several steps. As a consequence, dentists welcomed the development of simplified adhesives. In 2011, the new generation of universal adhesives was introduced, with the aim of replacing all previous generations.
The development of universal adhesives was firstly due to the success of self-etching adhesives, but total etching was still advocated. The result, a universal adhesive, must be considered a self-etching adhesive with a phosphoric acid conditioning option on enamel and/or dentine. Maximum flexibility resulting from the freedom of choice in etching technique and the preference of the practitioner was thus obtained.
CLEARFIL Universal Bond Quick, manufactured by Kuraray Noritake Dental, is a single-component light-curing bonding agent indicated for all direct and indirect restorations in combination with all etching techniques (total-etching, self-etching or selective-etching). The adhesive is also indicated for the surface treatment of zirconia- and silica-based ceramics. When compared with other one-bottle universal adhesives, CLEARFIL Universal Bond Quick exhibits RAPID BOND TECHNOLOGY. We asked Peter Schouten, Technical Manager at Kuraray Europe Benelux and a chemist with decades of experience in the dental industry, about his views on universal adhesives and CLEARFIL Universal Bond Quick.
Dental Tribune: Since the introduction of the first universal adhesive, a new generation of adhesives has been created that has enjoyed increasing popularity since then. What is your opinion about the system?
Peter Schouten: For me, the term “universal” remains debatable. There is no clear definition of a universal bonding system yet. When we look at what different manufacturers are saying about universal bonding systems, the term to me applies primarily to the etching technologies and the ability to adhere to all substrates currently used in dentistry, such as silica- or metal-based materials. In this case, we can really speak of “universal”.
What are the advantages and disadvantages of self-etching and total-etching technologies? How are universal adhesives positioned in relation to them?
In my home country of the Netherlands, there is a large group of self-etching users. In many other countries, most dentists still use the total-etching approach. And, of course, there are reliable three-step total-etching systems on the market. However, etching of dentine removes hydroxyapatite and creates a layer of collagen. Afterwards, the dentist tries his or her best to penetrate this layer again with a bonding system. Why not preserve the hydroxyapatite and create a reliable bonding to the hydroxyapatite itself? This is the basis of the gold standard two-step self-etching bonding, our CLEARFIL SE BOND. Now universal adhesives—at least CLEARFIL Universal Bond Quick—provide the advantage that dentists can use any etching technique without worrying about results that are less than optimal. It really is an open system.
How do universal adhesives perform on wet and dry dentine, as well as enamel, in combination with all etching technologies?
I am a strong believer in the self-etching technique as we have proven already. The wetness and dryness of dentine is always an issue in total-etching techniques. With CLEARFIL Universal Bond Quick, the instruction is to rinse and dry. Our universal adhesive has the capability of penetrating the dentine surface quickly and completely.
Kuraray is a pioneer in adhesive systems: the company introduced total-etching bonding in the 1970s and innovative self-etching technology in the 1990s. The secret to success of all universal adhesives seems to be the incorporation of the adhesive molecule MDP (10-methacryloyloxydecyl dihydrogen phosphate) developed in 1981 by Kuraray. What is the function of MDP?
Kuraray has over 40 years of experience in the development of phosphate monomers. In 1976, we had already developed Phenyl-P. By far the most important ingredient in our current bonding systems is the original MDP. We never would have reached the level at which we are today without this phosphate monomer. MDP is capable of creating a long-lasting bond to calcium in hydroxyapatite and to other metals. As MDP can chemically bond to Ca2+ ions, it forms stable, insoluble MDP–Ca salts present as nano-layers at the adhesive interface.
Kuraray Noritake Dental introduced CLEARFIL Universal Bond Quick at this year’s International Dental Show. According to the company, CLEARFIL Universal Bond is the best one-step adhesive ever developed. Briefly, what do you find noteworthy about the bonding agent?
The most remarkable thing is RAPID BOND TECHNOLOGY, enabling us to introduce the benefit of no waiting. This technology works in three steps: first, rapid penetration; second, fast polymerisation; and third, quick formation of a hydrophobic, hydrolytically stable bonding layer. It took our research and development lead Dr Yamato Nojiri many years to develop a cocktail of amide monomers that is superhydrophilic and turns after curing into a stable hydrophobic polymer. The addition of this amide monomer makes it possible to skip the waiting step. Fast polymerisation is achieved by a modified photoinitiator, releasing twice as many radicals in comparison with other initiators. The quickly formed stable bond derives from the combined action of MDP and the amide monomer. MDP bonds to calcium and amide monomer turns into a highly cross-linked hydrophobic polymer network.
The motto of CLEARFIL Universal Bond Quick is “Universal. Easy. Reliable.” Could you please explain that further?
I think that clinicians will be very satisfied with the bonding agent’s performance and wide indication range. It definitely will be used mainly for direct restorations with light-curing composite resins, but also for core build-ups, cavity sealing, treatment of exposed root surfaces and hypersensitive teeth. The pretreatment of the tooth can be done with any of the three etching procedures before applying this adhesive. For selective enamel etching and total-etching, phosphoric acid needs to be applied. I recommend K-ETCHANT Syringe etching gel. It is left in place for 10 seconds, followed by rinsing and drying. The product is very easy to use and not technique-sensitive. The result is a reliable bond because of the use of our proven MDP technology combined with the cross-linked hydrophobic polymer network.
Does CLEARFIL Universal Bond Quick adhere to any dental substrate (lithium disilicate, zirconia and metals)?
Yes, it does. CLEARFIL Universal Bond Quick is the ideal bonding agent in most situations. Bonding to tooth structure and to most direct and indirect filling materials can be performed with CLEARFIL Universal Bond Quick. For the pretreatment of silica-based ceramics (glass-ceramics); however, we advise the use of CLEARFIL CERAMIC PRIMER PLUS for the most optimal results.
What is known regarding combining universal adhesives with light-curing, dual-curing and self-curing composites without the use of primers? Can the dentist really combine them without any problems?
It can be used with all light-curing composites and compomers, with the exception of silorane-based composites. For use with self- and dual-cure composites, CLEARFIL DC Activator is needed. This catalyst activates the dual-curing mechanism of this adhesive. However, the addition of CLEARFIL DC Activator to the adhesive is not required when using it with CLEARFIL DC CORE PLUS or PANAVIA SA Cement Plus.
What do you see for the future of universal adhesives?
As long as we still need adhesives to bond our composites to tooth structure, I'm almost certain that single-bottle universal adhesives will become the most used systems. In vitro tests have shown good results. A universal, easy-to-use adhesive with few treatment steps and a short working time reduces the risks of errors. Of course, relevant long-term clinical research results are needed to prove the quality. Kuraray Noritake Dental, with its leading adhesive technology, will surely remain the leader in this field.
