Selective Adhesive Luting (SAL) is a hybrid technique for universal resin cements. It entails the application of a universal adhesive system only on easily accessible abutment surfaces, enabling simultaneous adhesive and self-adhesive luting in different portions of the abutment. A description of this novel technique and scientific evidence for the achieved effects is provided in this article authored by Prof. Breschi and colleagues from the University of Bologna. Its title:“Selective adhesive luting: A novel technique for improving adhesion achieved by universal resin cements”.

A VERSATILE RESIN CEMENT

PANAVIA™ SA Cement Universal is a universal resin cement that may be applied in the self-adhesive mode – without any additional components – in many clinical situations. It even offers great bonding performance to lithium disilicate without the need for a separate bottle of silane. In-vitro studies have shown that the resin cement is moisture tolerant and versatile, establishing a strong and durable bond to virtually all kinds of restorative materials as well as to enamel and dentin.

ENHANCING THE BONDING PERFORMANCE

On the side of the tooth, however, the best possible bonding performance is obtained by applying CLEARFIL™ Universal Bond Quick as a separate tooth primer. Hence, you may want to settle for this two-component adhesive luting technique in particularly challenging situations. It is still less complex than traditional adhesive luting and produces excellent outcomes.

MOISTURE SENSITIVITY AND WORKING FIELD CONSIDERATIONS

To function properly, however, universal adhesives need a completely dry working field, while self-adhesive resin cements are less sensitive to moisture. Thus, you might wonder which technique is best suited if you need the strongest possible chemical bond to enamel and dentin, but proper isolation with rubber dam is challenging or impossible – for example, because the abutment is short or the preparation margin is in a subgingival position. The solution in this case is termed Selective Adhesive Luting.

Selective application of a universal adhesive to those areas of etched enamel that are not at risk of being contaminated by moisture.

COMPOSITE RESTORATIONS IN DENTISTRY

Composite restoration is the most common procedure performed by the dentist. There are many restorative techniques and a variety of restorative materials used in dentistry. Regardless of the type of material, the method of restoration and where it is applied, common issue is air bubbles in or at the surface of the composite layers. The composite restoration should be homogeneous to ensure the tightness of the filling and its durability. Repairing bubble defects is tedious and sometimes requires the replacement of the filling or part of it. Depending on the type of composite (flowable or paste composite) and/or the placement technique, the amount of defects may vary, but there are several causing factors.

MATERIAL CHOICE

In the Flowable Injection Technique, we use flowable composites, which obviously flow easily but are also sensitive to incorrect application. The first cause of forming air bubbles is the homogeneity of the material itself. Bubbles can be incorporated in the syringe at the manufacturing stage or during use. By using premium products, we can be sure that the highest quality material is supplied, and that the structure and design of the syringe allows for proper operation to reduce the formation of air bubbles within the material.

IMPORTANCE OF SYRINGE DESIGN 

CLEARFIL MAJESTY™ ES Flow composite is designed to prevent the formation of air bubbles during dispensing. The special design of the syringe and plunger limit the possibility of dripping as well as backflow of the material during or after dispensing.

A unique safety feature inside the syringe is the special O-ring construction which prevents the material from flowing after pressure is released and at the same takes care for minimal retraction but avoiding the plunger from retracting too much.

RETRACTION OF PLUNGER

Another cause of air bubble formation is the incorporation of air into the syringe by deliberate retraction of the plunger. If the practitioner or ancillary staff have a habit of retracting the plunger after administering the composite, they may cause air to enter the syringe. During a following use the air will more than likely show up in the restoration as an air void.

IMPORTANCE OF PRESSURE ON THE INDEX

In the Flowable Injection Technique, we use a silicone index in which we apply the material to build up the tooth. The index should fit tightly to the tooth and should not move or being moved during injection. If it does air bubbles may show up. Pressing and then releasing the index will cause a suctioning effect and pull the composite away from the tooth as well as from the index. To avoid defects, constant pressure on the index should be maintained from the moment the material is injected until polymerisation.

Various modifications of the silicone index can be used to limit its mobility and reduce the risk of uncontrolled pressure on the tooth. Such an example is the index made on the interlip ("one yes one no") model, which provides a very high degree of stability as well as working safety.

WIDTH OF THE INJECTION HOLE

Another cause for getting air in the restoration is the width of the injection hole. If the hole is too tight, the index can be moved by the application tip during insertion or application. To avoid this problem, the hole could be widened to allow free insertion as well as manipulation of the tip during injection. A wider opening also allows any air to escape during dispensing. Most important , however, is to apply the material at continuous pressure and avoiding pulling out and reinserting the tip into the index. This may result in a non-uniform composite layer.

AWARD WINNING PRODUCT

For the 9^th year in a row, CLEARFIL MAJESTY™ ES Flow (Low) has been named a Top Product by Dental Advisor, which announced in its JAN/FEB 2024 issue its choices for dental materials and equipment found to deliver the best practice-based performance based on the publication’s annual review of such products.

ABOUT THE PRODUCT

CLEARFIL MAJESTY™ ES Flow, which is available in three different levels of flowability, was the Top Product honoree in the Direct Restorative Category and was also given Editor’s Choice award for its medium viscosity version - Low.

Rather than limit practitioners to a single viscosity that might not be ideal for all flowable composite indications, CLEARFIL MAJESTY™ ES Flow comes in one version firm enough to stay in place when applied, another malleable enough to fashion a specific shape, and a third runny enough to flow into every corner or undercut. The practitioner would thus be able to select the best version for the job at hand—choosing the high flowability variant for cavity linings and as a resin coat in immediate dentin sealing (IDS) procedures, but instead, the super low flowability option for direct veneer procedures and for the build-up of cusps, etc.

Beyond its handling advantages, this universal flowable composite, which incorporates Kuraray Noritake Dental Inc.’s Light Diffusion Technology, is highly esthetic, with optical properties that enable the practitioner to fashion lifelike restorations that integrate seamlessly with the surrounding tooth structure.

EVALUATION

The flowable composite tested by the 29 DENTAL ADVISOR consultants in 909 uses in their dental practices was the medium flowability variant CLEARFIL MAJESTY™ ES Flow (Low). Their evaluations focused on properties including placement/handling, esthetics, viscosity, and polishability, and they rated all these key features to be “excellent”. This led to a recommendation rate of 100% and a 98% overall clinical rating.

REMARKS FROM EVALUATORS

Among their comments were: “The material blended so well with the tooth structure that you had to really look to find the interface.”. “Readily apparent on radiographs.” and “One of the best flowable composites I have used.”.

Every dentist aims to polish to a high gloss without damaging the freshly modeled occlusal surface. Firstly, use high-quality polishing rubbers. The plural form is not accidental (Fig. 1). In my opinion, a single rubber systems are not capable of achieving an impeccable gloss in a safe manner. Be patient and gentle. Polishing requires time and a delicate touch.

Fig. 1.

Immediately after polymerization the composite is covered with an oxygen inhibition layer (Fig. 2). It is imperative to remove it by a brush and any polishing paste or a prophylactic sandblaster. The next step is to remove excess composite using abrasive discs, burs and firm polishing rubber points.

Fig. 2.

During polishing without water cooling, the rubber leaves crumbling on the composite surface (Fig. 3). These fragments can be spread across the restoration surface using a fine nylon brush. This allows for the polishing of each fissure and pit (Fig. 4).

Fig. 3.

Fig. 4.

The key to long lasting shine is polishing with gradation. Time to change a rubber point to the dark blue TWIST DIA for Composite rubber, which is more abrasive than light blue one (Fig. 5). Remember to apply gentle pressure and maintain a maximum speed of 8000 revolutions per minute. This way, you will achieve fine particles without the risk of overheating the pulp. The particles were once again spread over the entire surface. The thinner the bristle, the better the polishing effect in the grooves (Fig. 6).

Fig. 5.

Fig. 6.

Third round: use the light blue TWIST DIA for Composite rubber for a mirror-like gloss (Fig. 7). A beautiful gloss emerges beneath the particles. An alternative to thin nylon brushes is brushes made from natural goat hair (Fig. 8).

Fig. 8.

Polishing is not only a matter of aesthetics but, above all, function. The adherence of bacterial biofilm to a polished composite is significantly lower than to a rough surface (Fig. 9). My recipe for achieving a mirror-like gloss polish: high-quality diamond rubber points with gradation, used with sensitivity over an extended period (Fig. 10).

EMBRACE 2024 WITH OPEN ARMS –
IT BRINGS FORTH A YEAR OF NEW POSSIBILITIES

It is probably the best-known component of a dental product Kuraray Noritake Dental Inc. (Kuraray Noritake Dental) has ever developed: 10-Methacryloyloxydecyl Dihydrogen Phosphate, in short, the MDP monomer. Invented more than 40 years ago – the first product containing it was introduced in 1983 – MDP is still the leading functional monomer used to establish a long-term, durable and stable bond to hydroxyapatite in tooth structure and to metal oxides in restorative materials (oxide ceramics and metal alloys).

Nowadays, it is found in every dental adhesive and every component of a resin cement system with adhesive properties from Kuraray Noritake Dental. These include:

In addition, MDP has become an integral part of most universal adhesives and many adhesive cementation systems of other manufacturers as well. However, not all MDP is alike …

MDP: Chemical structure and mechanism of adhesion

The MDP monomer consists of three essential parts: A polymerizable group, a hydrophobic group and a hydrophilic group. The co-polymerizable methacrylate group has a terminal double bond enabling polymerisation. The large hydrophobic alkylene group – also referred to as the spacer – has the task to maintain a delicate balance between hydrophobic and hydrophilic properties of the monomer and offers great resistance to degradation. Finally, the hydrophilic phosphate group is responsible for acidic demineralisation, for chemical bonding with calcium in hydroxyapatite and for bonding with zirconia¹ (as well as with metal).

Bonding performance

Lots of in-vitro studies have been carried out to investigate the bonding behaviour of 10-MDP in the context of direct and indirect restorative procedures. No matter whether a cavity is to be filled with resin composite or an indirect restoration is to be placed, a strong and long-lasting bond to tooth structure needs to be established.Chemical structure of adhesive monomer 10-Methacryloyloxydecyl Dihydrogen Phosphate (MDP).

The critical substrate in this context is dentin, while bonding to enamel is found to be less challenging. That is why it is so important that (self-etch) adhesives containing 10-MDP show an extraordinarily high bond strength to tooth structure, particularly to dentin². In fact, 10-MDP also provides for a high bond stability over time by establishing an acid-base resistant zone on the adhesive interface³. This means that a great long-term performance may be expected. Fortunately, a great clinical long-term performance of products containing the MDP monomer has already been confirmed: A group from the University of Leuven (Belgium) has presented excellent results of a thirteen-year clinical trial involving the use of CLEARFIL™ SE Bond in 2015⁴.

When bonding to indirect restorations made of zirconia, the surface area of the ceramic should be increased by sandblasting⁵. Pre-treated in the recommended way, the bond strength to zirconia tends to be particularly high when MDP-based resin cement systems are used⁶. It is thus widely recommended by experts in the field of adhesive dentistry to employ MDP-containing primers or resin cements for the placement of zirconia-based restorations, especially those with a non- or less retentive preparation. The fact that products containing 10-MDP work well in this context has been confirmed in different clinical studies with observation periods of up to 10 years^7,8. The products used in these studies were PANAVIA™ 21, PANAVIA™ F2.0 and the latest version of the multi-component cementation system from Kuraray Noritake Dental, PANAVIA™ V5, which performed best.

Not all MDP is alike

Ever since the basic patent for MDP has expired, other manufacturers of dental adhesives and adhesive resin cements have started integrating the functional monomers in their own products. However, it has been revealed that there are differences in the purity of the MDP monomers synthesized and used, and that these differences have an impact on the long-term bonding performance of the products containing the MDP⁹. According to in-vitro test results, the Original MDP Monomer synthesized by Kuraray Noritake Dental stands out due to an unmatched level of purity. This purity has a positive effect on the microstructure and thickness of the hybrid layer formed on dentin, the intensity of nano-layering and the bond strength measured immediately as well as after artificial aging⁹.

Conclusion

The data summarized above reveals that after 40 years in clinical service, the Original MDP Monomer from Kuraray Noritake Dental is still a class of its own. It has everything needed to establish a strong and long-lasting bond to tooth structure, resin composite and metal oxides, and is therefore a valuable component in virtually every adhesive system. In order to provide for a high bond quality, however, it may be best to use an MDP monomer with a confirmed high purity – the Original MDP Monomer.

Is it safe to use the single-component PANAVIA™ SA Cement Universal to lute virtually all your indirect restorations?

Did you ever ask yourself how many components are really needed to safely cement your silicate-ceramic, zirconia or resin-based restorations? With PANAVIA™ SA Cement Universal, a single component is usually sufficient. Containing an unreacted silane coupling agent – the LCSi monomer – and the original MDP monomer, the dual-cure, self-adhesive resin cement adheres to tooth structure and to various restorative materials including the popular silica-based ceramics without the need for a separate primer.

For those wondering how it works and if it really works as well as desired, Kuraray Noritake Dental Inc. has created a scientific brochure. It contains in-depth information about the drivers of chemical adhesion contained in PANAVIA™ SA Cement Universal and its characteristic properties. The main part, however, focuses on the results of scientific studies – most of which have been conducted in external laboratories. With the aid of artificial aging, different testing devices and various experimental set-ups, the researchers have checked the resin cement thoroughly. The study results shed light on the behaviour of the material when used in the context of bonding to different restorative materials and different types of tooth structure. Self- and light-curing modes are compared, aging effects investigated and different moisture conditions taken into account.

As a whole, the collected data allows for a precise prediction of the clinical behaviour of PANAVIA™ SA Cement Universal. This valuation has already been confirmed by clinical experience of dental practitioners from all around the world. Moreover, the results of a first clinical study, which is also found in this compilation, are a proof of its exceptional performance.

VOUS ÊTES-VOUS DÉJÀ DEMANDÉ POURQUOI LES PRODUITS DE LA MARQUE PANAVIA™ OFFRENT D‘AUSSI BONNES PERFORMANCES?

Vous savez probablement qu‘ils contiennent tous le monomère MDP original développé au début des années 1980. Ce monomère adhésif a beaucoup fait parler de lui pour son excellence. Monomère d‘ester de phosphate, il forme une très forte adhésion à la structure dentaire, à la zircone et aux métaux dentaires. Il a été utilisé dans chaque produit PANAVIA™. Outre le MDP, d‘autres technologies et ingrédients catalytiques sont d‘importants contributeurs qui soutiennent les performances de nos solutions de collage.

INGRÉDIENTS INFLUANÇANT LA RÉACTION DE POLYMÉRISATION

Parmi ces autres technologies et ingrédients déterminants, notons le catalyseur qui provoque le processus de polymérisation. Différent du monomère MDP utilisé dans chaque produit PANAVIA™, le catalyseur de polymérisation a été amélioré en permanence depuis l’introduction de PANAVIA™ EX en 1983. Ainsi, de nouvelles versions ont été développées pour PANAVIA™ 21, PANAVIA™ Fluoro Cement et PANAVIA™ V5, entre autres. Un autre important composant qui influence également le processus de polymérisation est la Touch Cure Technology utilisée dans deux des trois principaux produits de la ligne PANAVIA™ actuelle : PANAVIA™ V5 et PANAVIA™ Veneer LC. Cette technologie est intervenue pour la première fois dans PANAVIA™ 21, qui a été lancé en 1993. Lorsque l’activateur chimique de polymérisation contenu dans l’apprêt à auto-mordançage entre en contact avec la pâte de ciment de résine, la polymérisation de la colle de l’interface adhésive est accélérée, apportant ainsi une meilleure adhésion du ciment de résine. En développant PANAVIA™ V5, nous avons revu et actualisé considérablement la composition chimique des produits PANAVIA™ existants. La Touch Cure Technology a également été adoptée pour le cas d’une utilisation de PANAVIA™ V5 Tooth Primer en concomitance avec PANAVIA™ V5 Paste. Pour coller des facettes avec PANAVIA™ Veneer LC, nous utilisons aussi PANAVIA™ V5 Tooth Primer afin de préparer les dents. Cet apprêt recourt lui aussi à la Touch Cure Technology pour obtenir une connexion adhésive avec la dent sans affecter le temps de travail de la pâte de ciment.

MONOMÈRES ADHÉSIFS ADDITIONNELS

Dans le domaine des monomères adhésifs également, nous n’avons pas ménagé nos efforts : Nous avons développé le monomère LCSi, un agent combinant le silane à longue chaîne carbonée qui a permis d’intégrer la fonction d’un apprêt céramique à notre ciment de résine auto-adhésif universel PANAVIA™ SA Cement Universal. Avec son degré élevé d’hydrophobie, ce monomère apporte une force d’adhésion stable sur le long terme. D’une manière générale, on peut dire que la durabilité d’adhésion peut baisser en raison d’une réaction hydrolytique endommageant l’adhésion chimique entre la silice contenue dans la vitrocéramique et l’agent combinant le silane.

TROIS PRODUITS COUVRANT PRATIQUEMENT TOUS LES BESOINS

En combinant intelligemment ces technologies et ingrédients, nous avons réussi à développer une gamme de ciments de résine qui couvre pratiquement tous les besoins. Avec PANAVIA™ V5, PANAVIA™ SA Cement Universal et PANAVIA™ Veneer LC, il est possible de traiter une grande variété de cas. Ces produits permettent l’assemblage de nombreux types de restaurations, d’appareils prothétiques et la pose de tenons pour offrir d’excellents résultats à condition d’être utilisés conformément aux consignes d’utilisation.

PANAVIA™ V5 est le ciment de résine offrant le champ d’utilisation le plus vaste parmi les trois systèmes de collage que nous venons d’évoquer. Il couvre pratiquement toutes les utilisations visées par les deux autres ciments. C’est pourquoi le praticien dentaire peut, en fonction des cas se présentant à la clinique et des besoins des patients, trouver le bon système de collage pour le traitement en choisissant parmi ces trois principaux produits de ciment de résine : PANAVIA™ V5, un ciment de résine avec un vaste champ d’applications, PANAVIA™ SA Cement Universal, un ciment de résine auto-adhésif simple et facile à manipuler et PANAVIA™ Veneer LC quand il s’agit d’adhésion de facettes stratifiées.

EXPLORER DE NOUVELLES OPPORTUNITÉS

L’avantage du développement de technologies au sein d’une société telle Kuraray Noritake Dental est que leur application ne se limite pas à un certain produit ou groupe de produits. Le département R&D étudie toujours comment tirer profit des bénéfices de ces technologies pour d’autres applications. C’est le cas par exemple pour KATANA™ Cleaner, qui a été mis sur le marché en 2019. Ce nettoyant peut être utilisé pour éliminer la salive, le sang, la colle provisoire et d’autres contaminants qui peuvent adhérer aux surfaces des dents ou des appareils prothétiques pendant les essayages et le collage provisoire d’une prothèse. Ce produit unique a été développé en exploitant la fonction tensioactive du monomère MDP.

CONCLUSION

L’excellence de la gamme PANAVIA™ actuelle découle principalement de nos connaissances et de notre expérience de longue date dans le développement de ciments de résine et solutions adhésives dentaires. Nous savons comment améliorer nos technologies existantes, ne cessons jamais d’en développer de nouvelles et recherchons continuellement la meilleure façon de combiner les composants éprouvés avec les nouveaux pour obtenir le meilleur résultat possible. Au fil des étapes de la procédure de développement de produits, des tests cliniques sont réalisés et les retours de praticiens dentaires sont recueillis afin de prendre en compte les conditions extrêmes dans l’environnement bucco dentaire. Cette stratégie a brillamment fait ses preuves tout au long des 40 dernières années, et nous sommes convaincus qu’elle nous aidera à développer de nombreux autres produits innovants qui offrent un soutien idéal dans nos efforts pour améliorer la santé bucco-dentaire des patients.
