A middle-aged patient sought dental advice because she felt uncomfortable with the aesthetic appearance of her upper front jaw, specifically regions 11, 12, 21 and 22. Additionally, she was not happy about the diastema between her upper central incisors.

Fig. 1: Initial situation.

The oral examination showed four crown regions (12-22) and revealed that all of them have deteriorated. Tooth 21 had undergone an endodontic treatment, while teeth 11 to 22 have been newly built up. Due to the deteriorated conditions, all affected teeth were taken into consideration in the planning and designing of new restorations, including the intention to close the diastema between the width-to-length-ratio for the incisors.

The best suitable material for a natural look in combination with a close gingival attachment to the restoration is, in this case, zirconia, because of its biocompatibility and gentleness to the gingival region. The KATANA^TM Zirconia series from Kuraray Noritake Dental, offers a line-up of high-quality materials combined with true-to-life aesthetics, due to its natural color gradient within the material.

To achieve an even more natural-looking and aesthetic restoration, CZR FC Paste Stains were used externally on the zirconia surface.

Fig. 6: Characterization of the restoration.

As often done, Cervical 2 was used to give an orange tint to the cervical area, to accentuate even better the natural tooth gradation. For the incisal areas, Grayish Blue in combination with Value was used to enhance transparency and opalescence. Same procedure applied to the approximal areas. Mamelon Orange 2 was used to reproduce dark orange stain on the mamelons.

During a period of five years, annual check-ups showed intact crowns and a healthy gingiva. Additionally, the durability of the restorations, including their mechanical and optical properties revealed no signs of deterioration.

A strong and durable bond between the tooth and the restoration is a decisive factor influencing the long-term performance of dental restorations. The quality of the bond, however, is not only affected by the bonding agent or cementation solution used, but also by the condition of the bonding surface. For those who would like to ensure clean tooth and restoration surfaces in an easy way, Kuraray Noritake Dental has developed KATANA™ Cleaner, a universal cleaner with MDP salt and a pH of 4.5 for intra- and extra-oral application.

It has been proven that proteins present in saliva and blood have a negative effect on the performance of dental adhesives. Especially in indirect procedures, however, it is impossible to keep the bonding surfaces free of oral fluids. At try-in at the latest, the prepared tooth and the restoration are contaminated and need to be cleaned. Rinsing with water does not have the desired effect, and even with many available cleaners, a certain amount of proteins are usually left on the surface. Tests show that by using KATANA™ Cleaner or by sandblasting, the desired high cleaning effect needed is obtained, without compromising bond strength. This is true for KATANA™ Zirconia restorations, while KATANA™ Cleaner also leads to the desired results on dentin and enamel – surfaces in the oral cavity for which sandblasting and most of the other cleaners are not indicated.

The use of KATANA™ Cleaner offers yet another advantage: the cleaning procedure is extraordinarily simple, quick and neat. The universal cleaner comes in a bottle with an innovative flip-top cap, enabling single-handed dispensing onto the dish. It is then rubbed into the surface of the restoration and the prepared tooth structure or the abutment for ten seconds, rinsed with water and dried. Thanks to the high surface activity of MDP salt, these ten seconds are sufficient to remove the proteins on the substrate almost completely, creating conditions very similar to those found on a non-contaminated bonding surface. Subsequently, the selected bonding agent or cementation solution – e.g. PANAVIA™ V5 or PANAVIA™ SA Cement Universal – is applied according to the maufacturer’s usage instructions.

The result is a strong long-lasting bond, which gives users a peace of mind. Pilot users who have already tested the product agree that KATANA™ Cleaner is the easy way to optimise bond quality and streamline any adhesive procedure.

As co-editor-in-chief of the Journal of Adhesive Dentistry, Prof. Bart Van Meerbeek is one of the most respected authorities on the topic of dental bonding agents. Here, he discusses how they have advanced over the last three decades and what the future of adhesive dentistry might look like.

Prof. Van Meerbeek, how have bonding agents changed and advanced since you first began studying them?

I believe that the great progress dental adhesive technology has undergone in the last 30 years, and the progress in bonding agents in particular, has had a great impact on the field of dentistry and particularly on restorative dentistry, of course. Many of the current restorative dental procedures make use of adhesive materials and techniques and have advanced greatly compared with when I wrote my dissertation more than two decades ago on the topic of adhesion to dentine. Adhesion to enamel is, of course, relatively easy to achieve in comparison with adhesion to dentine, and when I first started researching this topic, I was limited to conducting clinical trials in which we were confronted with a relatively high number of restoration losses in the short term. I was lucky to have been able to witness first-hand the fast advancements dental bonding has made, having conducted research in this field now for nearly 30 years.

At a certain point, the research community started to realise that there is a smear layer in-between, which is created through cavity preparation, and that this layer interferes with bonding. If you want to achieve successful micromechanical and chemical bonding to the substrate, you first need to do something with this smear layer.

After this, we entered the era of conditioners and primers. In the past, the restorative community had been a little bit afraid of using phosphoric acid owing to its potential for pulp irritation. More and more, however, dental professionals began to use etchants with this chemical in them, as well as primers that effectively promoted bonding between the adhesive resin and dentine. While having achieved excellent bonding performance with multistep adhesives in the laboratory, as was later confirmed in clinical studies, further design and development of adhesive materials next focused on simplification and shortening of bonding procedures.

Out of this, two kinds of adhesives, making use essentially of two different bonding modes, arose: the etch-and-rinse adhesives and the self-etch, or etch-and-dry, adhesives. The newest generation of universal adhesives now enables dental practitioners to choose which of the two bonding modes to apply with one single adhesive formulation.

What advantages do bonded restorations offer over more traditional methods?

Bonded restorations are minimally invasive—the dentist doesn’t have to remove non-diseased tissue to create undercuts to keep the restoration in place, allowing for a more conservative approach. Keeping as much enamel as possible should be a goal of any restorative procedure, as it is simply the best tissue to bond to. Although bonding to dentine has always remained more challenging and has actually slowed down our adhesive endeavours for a long time, adhesively restoring teeth, involving also effective bonding to dentine, can today be achieved in a reliable, predictable and durable way.

Along with highly successful implantology to replace missing teeth, lessening the need for bridges, solitary tooth restorations have substantially increased in number. Bonding promoted the additional shift from conventional tissue-invasive crowns to tissue-preserving partial tooth restorations, as modern adhesives can hold such partial restorations in place on rather flat and even non-retentive surfaces. In addition, bonding procedures allow for more natural-appearing restorations to be achieved by techniques to adhesively lute aesthetic restorations made of glass-ceramics and even the strong zirconia ceramics that no longer can be considered non-bondable.

What is your opinion regarding the current generation of universal adhesive solutions?

I think that this generation is very good, but that they are still not always as good as the more traditional gold standard two-step self-etch and three-step etch-and-rinse adhesives when it comes to their intrinsic bonding potential to dental tissue. However, I do see it as a positive that many of these universal adhesives integrate the MDP monomer, which should be considered to be one of the best functional monomers available today, though it needs to be present at a high concentration and purity level.

The MDP monomer is, generally speaking, excellent at bonding to zirconia as well. When it comes to bonding to different kinds of ceramic as well as resin-based composite restorative materials, it is always helpful to know which universal adhesives contain silane and are claimed to no longer need further treatment of the restoration. This has the advantages of lower technique sensitivity and fewer procedural steps—provided that it does, of course, work. There is current scientific evidence that the silane incorporated in today’s acidic aqueous universal adhesives is, however, insufficiently stable. Fortunately, research is underway to develop new universal adhesives that contain other silanes with higher stability in water at higher acidity.

Overall, I believe that a restoration primer that contains a high concentration of silane along with the MDP monomer is still more effective than many universal adhesives for bonding to restorative materials, since these universal adhesives can contain many other ingredients that create a kind of competition within the material to reach and interact with the substrate surface, leading to lesser bonds.

Another shortcoming of universal adhesives is their thin film thickness and relatively high hydrophilicity, promoting water uptake and hence making them sensitive to hydrolytic degradation. In this light, it’s important to note that, when a viscous and hydrophobic flowable composite is applied on top of a universal adhesive, it can make up for this somewhat and allow for durable bonding to take place.

Is the MDP monomer crucial to the ultimate success of universal adhesives? Are there other factors that can influence this?

Well, it’s very clear that the MDP monomer is one of the most effective monomers available, given its primary chemical binding potential to hydroxyapatite. However, there are significant differences in the MDP monomer purity and concentration levels between these products, factors that are affected by whether or not the monomer is synthesised by the company itself or whether this process is outsourced. Essentially, a universal adhesive that contains a high concentration of very pure MDP monomer should perform the best.

Are there any specific advantages that a self-etch adhesive possesses?

The biggest advantage is that it doesn’t remove all hydroxyapatite and minerals present in dentine and so keeps the weaker dentinal collagen protected. Phosphoric-acid etching results in relatively deep and complete demineralisation with collagen exposure, making the bond more prone to degradation. Partially maintaining minerals around collagen using a mild self-etch adhesive additionally allows for strong ionic bond formation to take place when the adhesive in particular contains the functional monomer MDP. In addition, one should be aware that, while chemical binding doesn’t necessarily lead to higher bond strength, it can create better long-term bond durability.

What do you see as the next step in adhesive dentistry?

One possibility is to reduce the number of steps in the adhesion process with the final goal of having self-adhering restorative materials. There have been developments in this direction, including studies and commercial products, though the products haven’t always proved to be very effective and their bond durability is unclear. Now, however, there are newer materials coming to market with claims that they can be used with no pretreatment. Their clinical effectiveness, nevertheless, still needs to be proved and guaranteed before such self-adhering restorative materials could be used as true amalgam alternatives in routine dental practice.

Another possibility, and current R & D hype, is the development of bioactive adhesives. Many dental researchers and many companies want adhesives not only to deliver good bonding performance but also to have certain therapeutic benefits. What exactly a bioactive adhesive is depends on who you’re talking to. Some researchers believe that they should have antibacterial qualities, whereas others state that remineralisation of dentine and pulpal cell interaction are needed to qualify for the term “bioactive”. We certainly need to investigate whether we can give these materials these additional properties, but on one condition: that the adhesive material does not lose any of its original bonding abilities. That, in my opinion, is the biggest challenge for the future of adhesive dentistry.

As a company, Kuraray Noritake Dental is committed not just to creating innovative products, but also to building upon our successes. A perfect example of this approach is CLEARFIL Universal Bond Quick, our newest universal dental bonding agent. A descendant of the original CLEARFIL BOND SYSTEM F and CLEARFIL SE BOND, this one-step adhesive eliminates the need for waiting, rubbing or applying additional layers. With the introduction of a flip-top cap, CLEARFIL Universal Bond Quick is now more compact and efficient than ever.

Easier than ever to use

Thanks to the new flip-top cap, the bottle can easily be opened, manipulated and closed with just one hand. In addition, its unique nozzle allows for controlled dispensing of the adhesive and ensures that there is minimal wastage. Together, these improvements are intended to enable ideal results for both the dentist and the patient.

Rapid bond technology

Though its container may be different, the patented monomer technology of Kuraray Noritake Dental still forms the backbone of this product. Other adhesives tend to rely on “slow monomers” with relatively slow dentinal penetration, but CLEARFIL Universal Bond Quick combines Kuraray’s famous MDP monomer—scientifically proven to deliver stronger and more stable bonds than other manufacturers’ MDP—with hydrophilic amide monomers. This allows it to penetrate the dentine faster and more efficiently and provide a stable, moisture-resistant sealing of the cavity.

Combine with PANAVIA SA Cement Universal and CLEARFIL DC CORE PLUS

This universal adhesive pairs excellently with CLEARFIL DC CORE PLUS, a dual-cure, radiopaque core build-up material, to deliver durable, long-lasting restorations that dentists can trust. Delivered in a convenient automix system, CLEARFIL DC CORE PLUS possesses excellent compressive and flexural strength, with a filler loading weight of 74wt%.

CLEARFIL Universal Bond Quick is also suited for use with PANAVIA SA Cement Universal, a resin cement that similarly utilises MDP monomer technology for durable bonding. PANAVIA SA Cement Universal possesses a stable three-year shelf life at room temperature, effectively eliminating the need for refrigeration, and its improved endo tip allows for greater precision and control over cement placement during post cementation.

By combining excellence in performance with simplicity in use, Kuraray Noritake Dental’s CLEARFIL Universal Bond Quick represents an evolution in dental bonding agents. 

As a dental technician with many years of experience, Björn Roland has always pursued one goal in his lab: restorations that seamlessly mimic natural dentition and possess reliable functionality. Here, he discusses how he integrates Kuraray Noritake Dental’s dental solutions into his daily workflow and shares some tips for creating aesthetically-pleasing dental restorations.

Could you speak a little bit about your dental journey and how you were first introduced to Kuraray Noritake Dental’s range of products?

ROLAND: Well, I was first introduced to these products when I was in Japan about 15 years ago. I was there to undertake a course at the Osaka Ceramic Training Center of Shigeo Kataoka, but I had the possibility during this time to visit courses conducted by Hitoshi Aoshima. Aoshima is the person primarily responsible for Noritake Porcelain and who had the idea for the colouring, and he was also responsible for the idea of internal staining. I also had the possibility to complete a course with Aoshima and visit his dental lab in Tokyo, which enabled me to begin working with Noritake porcelain when I arrived back in Germany.

You spoke at IDS 2019 about the evolution of the KATANA™ Zirconia range, starting with the 2013 introduction of KATANA™ Zirconia ML. When did you first start working with this product?

When Kuraray Noritake Dental was formed in 2012, I was lucky enough to be one the first dental technicians to experience the multilayered technology that forms the backbone of KATANA™ Zirconia, to test it out before it was released to the German market. Prior to this, there was only a monocoloured zirconia material available, which you could stain yourself by dipping it into a staining solution, but I was never a big fan of it. From the moment that Kuraray Noritake came up with its multilayered approach, I could see the potential of KATANA™ Zirconia -simply put, it was easy to use and had a nice and aesthetic colour shift when used for restorations.

As a dental technician, do you use KATANA™ Zirconia in your everyday workflow?

In our laboratory we only use KATANA™. Of course, not everything is made from the multilayered variety—we have primarily used the monocoloured KATANA™ HT for the framework in the past, though we do use the multilayered option for monolithic restorations and for certain frameworks.

Do you use KATANA™ Zirconia in combination with CERABIEN™ ZR porcelain?

Yes, always. For me, it is a perfect combination. Not only are they easy to use together, but they also combine to create aesthetic restorations with great, natural colour and a high level of flexural strength. In our laboratory, everyone uses CERABIEN™ ZR porcelain, from those who are just starting with ceramics through to the experienced and highly skilled dental technicians. Even technicians who have come from other dental laboratories and tried other porcelain materials have adapted very quickly to using it and seem to really like it. The chipping risk with CERABIEN™ ZR porcelain is very low, and we truly admire the brilliance of the colour.

Is CERABIEN™ ZR porcelain a material, in your opinion, that can benefit those with expert knowledge of porcelains?

Of course. For those who are experienced in dealing with ceramic materials and understand how they behave, they can absolutely achieve high-end results with CERABIEN™ ZR. It’s important to remember, though, that even dental technicians who aren’t so familiar with ceramic veneering are also getting good results out of it - it’s not too difficult to use and get good results.

Do you use any other Kuraray Noritake Dental products in your dental lab?

Apart from KATANA™ and CERABIEN™ ZR, one product that I personally like and use from Kuraray Noritake Dental is Meister Cones, which are these small paper cones that assist with the finishing and polishing of porcelain surfaces. I brought them back with me to Germany from Japan and find them to be very handy in the laboratory.
