Interview with Dr. Ludivine Facon

Individual prophylaxis, early defect detection and treatment, minimally invasive restorative techniques: In her joint dental practice in Anstaing, France, Dr. Ludivine Facon does everything in  her power to keep her patients’ teeth healthy for their lifetime. When we met her at the International Dental Show in Cologne, where she was a speaker for Kuraray Noritake Dental Inc., we asked her to share information about her treatment philosophy and how flowable injection fits into her overall approach.

Your treatment philosophy seems to be minimally invasive. Would you please tell us a bit more about it?

Ever since I started treating patients, my priority has always been to preserve the dental tissues and to be as minimally invasive as possible when restoration is required. My interest in prevention started with my thesis in 2000, which focused on oral health prevention in Quebec, Canada, a country where prophylactic care is an integral part of dental treatment. I have always been highly interested in individual prophylaxis, which naturally led me to focus on minimally invasive treatments. My goal is to stay as low as possible on the therapeutic gradient, always thinking about the long-term benefits for the patient.

What are the benefits of this approach for your practice?

Integrating prophylaxis for every patient into my practice allows me to work with excellent surface conditions for bonding. The oral environment is sanitized before applying conservative restorations, and carious lesion removal is kept to a minimum.

When defects – be it a carious lesion or severe tooth wear – are present, I use the following instruments and materials that allow for truly minimally invasive interventions:

• Rondoflex 50-micron sandblaster to roughen the surface,
• Micro diamond burs to remove what is necessary,
• Layered composites for single-tooth restorations,
• Injected composites when multiple teeth are involved.

Case predestined for composite injection, as multiple teeth in the maxilla need to be treated (smile makeover).

What dental materials do you use for your restorative procedures?

I am a hands-on dentist, and in my daily practice, I strictly follow surface preparation and bonding protocols recommended for CLEARFIL™ Universal Bond Quick 2 (Kuraray Noritake Dental Inc.). In addition, I use high-quality composites from Kuraray Noritake Dental Inc. For layering, CLEARFIL MAJESTY™ ES-2 Premium Enamel and Dentin are my got-to solution, while I use CLEARFIL MAJESTY™ ES Flow Low for injection.

What are the benefits of a conservative approach for your patients?

Patients appreciate the fact that my treatment approach is as conservative as possible while still allowing for easy reintervention if necessary, preserving as much healthy dental tissue as possible. Another significant advantage is the moderate cost, which makes the treatment more accessible.

How does composite injection fit into this philosophy?

This technique allows for an easy reconstruction of multiple teeth by transferring a wax-up designed in the lab into the mouth via an injection of modern flowable composite into a transparent silicone index. Patients like this technique because it is aesthetic, reliable, reproducible and minimally invasive. A major advantage is that it allows for touch-ups and repairs, making it a reassuring solution. In some cases, no tooth preparation is needed at all—we simply add material, making the whole treatment truly non-invasive.

Why do you think this technique is promising?

It is a trendy and promising technique because:

• It is non-invasive --> preserves tissues --> aligns with minimally invasive dentistry.
• It is predictable --> due to the index, the technique is reproducible.
• It is easier than traditional layering --> saves chair time and improves patient comfort.
• It is cost-effective --> a cheaper alternative to ceramic veneers.
• It allows for repairs at any time, making it a reassuring option.

How did you proceed before knowing this technique?

In the anterior region, I used traditional composite layering with a wax-up and a palatal silicone index. It allowed me to rebuild the palatal wall and provide for precise incisal edge placement. In the posterior region, I used inlays, onlays, or overlays made of lab-processed reinforced composite or lithium disilicate.

Transparent silicone index with injection hole used to inject the flowable composite and restore the tooth to its planned shape.

What made you start using the new technique?

There has been an explosion in demand for smile enhancements, especially among young adults. The composite injection technique is an appealing alternative for reshaping smiles in young patients with intact teeth but unsatisfactory size or shape. It is less invasive than veneers, which have gained popularity due to social media trends, but often require significant tooth preparation.

How did you proceed in the beginning?

I first discovered the technique in a specialized journal in 2019, then trained myself using online tutorials. Of course, there were some trial-and-error moments, but it is a very accessible technique—even for beginners. To achieve optimal results, I believe that proper case selection and treatment planning are key. One of the most important preconditions for aesthetic outcomes is that the patient’s teeth have a simple shade structure. If the shade structure of the teeth is complex or the required restoration is large, it is better to layer the dentin before injecting the enamel. Moreover, it is essential to produce two models in the wax-up phase, not just one: An “intermediate wax-up model” with every other tooth featuring the wax-up, while the remaining teeth remain unmodified. The second is a “full wax-up model” with all teeth reshaped.

Considering these aspects, it is possible to obtain great outcomes quite quickly. The learning curve is steep, however – as with every new technique to be implemented – you need to step out of your comfort zone.

Apart from CLEARFIL™ Universal Bond Quick 2 and CLEARFIL MAJESTY™ ES Flow Low you already mentioned, what instruments and materials do you use?

For treatment planning including the wax-up, I use digital technology via Smilecloud, but a traditional wax-up works just as well. The production of the silicone index is the most delicate part when doing it in-house. I recommend using EXACLEAR (GC), the only truly effective transparent silicone currently available. Adjacent teeth are isolated with PTFE tape. Finishing instruments that have proven their worth are:

• Scalpel Blade No. 12,
• 3M™ Sof-Lex™ Contouring and Polishing Discs (Solventum),
• Red-ring fine diamond burs,
• TWIST™ DIA for Composite polishers (Kuraray Noritake Dental Inc.).

Intermediate wax-up model: One tooth with wax-up followed by one tooth without.

Full wax-up model.

Do you believe that the quality of the outcome is affected by the composite material you use?

Absolutely! New high-filled flowable composites, like CLEARFIL MAJESTY™ ES Flow Low, offer excellent mechanical properties and polishability, making them very promising.

Highly aesthetic treatment outcome after injection of CLEARFIL MAJESTY™ ES Flow Low.

What material characteristics impact overall quality?

First of all, the optical properties or shade matching ability of the material are crucial. I like the fact that I can select from a variety of shades when using CLEARFIL MAJESTY™ ES Flow. Once the right shade is selected and the thickness of the injected layer does not exceed 1 mm, the optical properties of the restorations may be expected to be exceptional.

Moreover, we need a material with great flow properties (fluid, but not too runny), which is virtually void-free. I prefer using low viscosity flowable composites like CLEARFIL MAJESTY™ ES Flow Low (two other flowabilities – HIGH and SUPER LOW – are also available). The physical properties (mechanical strength) and polishability plus polish retention are also important. They are usually excellent with premium flowable composites.

What are your most important clinical tips and tricks?

For beginners:

• Press firmly on the cervical area of the silicone index to reduce excess material upon removal.
• Finish the proximal area thoroughly before moving to the next injection step. This way, you provide for perfect key positioning for the following teeth.

If you follow the protocol, the technique is very beginner friendly!

What is your opinion about the emerging hybrid "layering & injection" technique?

This hybrid technique complicates the original injection technique, which is meant to simplify composite restorations. However, it is very useful in cases where aesthetic complexity requires layering. For maximum mimicry with this technique, I would love to have injectable composites in an enamel shade at my disposal.

Would you please share your final thoughts with us?

Take your time planning! Observe, document, take photos, use digital tools! Less is more.

Dr. Facon, thank you very much!

PANAVIA™ Veneer LC WINS PREFERRED PRODUCT AND RESEARCH AWARDS

PANAVIA™ Veneer LC has been singled out for a Research Award in the category Research – Veneer Cement by Dental Advisor and for a Preferred Product Award in the category Cement: Esthetic Resin. Published in the January/February 2025 issue of the US-based organisation, the annual Top Product, Preferred Product or Research Awards are given to those materials and devices deemed by the publication’s consultants to deliver the best practice-based or lab-based performance in their categories.

BENEFITS IN A NUTSHELL

PANAVIA™ Veneer LC is a specialized veneer cement designed to provide exceptional bond strength to various substrates, along with outstanding gloss retention and wear resistance. The resin cement utilizes smaller-diameter spherical filler particles, facilitating easy dispensing from the syringe and excellent flowability for minimal film thickness. All of these attributes contribute to virtually no change in gloss or surface appearance of veneer margins over time.

EXCELLENT PROPERTIES IN VITRO

To assess the scientific performance of PANAVIA™ Veneer LC, its features and physical properties, specifically its bond strength to various substrates after artificial aging and its wear resistance, were tested in the Dental Advisor Biomaterials Research Center. The investigators’ testing of these attributes reflects the challenges such products must meet – “Ideally, esthetic veneer cements should have a long working time, curing on demand, excellent color stability, and high strength”.

To assess bond strength to dentin, enamel, IPS e.max CAD, and zirconia, the cements were subjected to six months of artificial aging using thermocycling. To test wear resistance after toothbrush abrasion, the testing method involved measuring depth of wear, change in surface roughness, and change in gloss based on a simulation of about 5.5 years of regular toothbrush use.

The investigators reported that PANAVIA™ Veneer LC “had the best gloss retention of the three cements tested and a very even wear pattern,” noting further that “having limited surface roughness after toothbrush abrasion can help lower staining and bacterial adhesion.” Overall, they said, “The PANAVIA™ Veneer LC cement system showed excellent adhesion properties and exceptional gloss retention and wear resistance,” concluding:

OUTSTANDING RATING OF 96 PERCENT

In addition, the product was tested in the clinical setting. 25 clinical evaluators used PANAVIA™ Veneer LC cement system in their dental offices. After a total of 166 uses, the light-curing resin cement received “excellent” to “very good” ratings with regard to completeness of the kit, the shade of the try-in pastes, ease of clean-up of the try-in pastes and excess cement, viscosity, working time and lack of shade shift after curing.

The evaluator’s clinical tips included:

• „Use a micro brush or rubber tip to clean up excess cement before curing.”
• „Apply glycerin gel to the margins after placing the veneer with the cement to eliminate the oxygen inhibition layer and ensure a complete cure before light curing through the gel.”

In their comments, they praised the ease of use of the system, the design of the syringes, the shade options and shade match between try-in and cement shades, e.g.:

• “The white shade of the cement was opaque enough for efficient masking of discolored tooth structure.”
• “Great esthetics, very easy to use, complete system.”

This resulted in an overall clinical rating of 96 percent and an equally high recommendation rate.

Interview with the team at Kuraray Noritake Dental Inc., who developed and brought to life this new universal adhesive.

Streamlining, enhancing and refining adhesive procedures – these are the aims of an 5-person team at Kuraray Noritake Dental Inc. in Japan. Recently, the team has developed a next-generation universal adhesive CLEARFIL™ Universal Bond Quick 2 that offers quick and easy application combined with an optimised bonding performance. To learn more about the goals and achievements of the development project, and the benefits of the product, we had a conversation with them.

From left to right: Ryo Matsuura and Ryota Murayama (R&D Department), Kazutoshi Ikeda (Production Department), Marina Okada and Yamato Nojiri (Planning & Development Department).

Why did you decide to improve CLEARFIL™ Universal Bond Quick?

Universal adhesives like CLEARFIL™ Universal Bond Quick are very well received by dental practitioners all over the world mainly due to their versatility and procedural simplicity. In the clinical setting, however, we have identified room for improvement. For example, it can be difficult to establish thin, uniform and strong bonding layers with the currently available products. Water and solvents in universal adhesives often limit the formation of a strong bond layer. A thin bonding layer and the relatively thick oxygen inhibition layer make this type of bonding agent susceptible to degradation by water sorption from dentinal moisture. Highly viscous bonding agents also complicate the ease of application in small cavities and can easily lead to pooling of the adhesive in critical parts of the cavity. Adhesives with a relatively high viscosity may pool or accumulate along margins, and may form a layer that is too thick and may change the morphology of the abutment tooth, a critical factor potentially affecting the fit of an indirect restoration. Generally, bonding agents with a low film thickness and/or are low-filled or unfilled, in turn have a potentially negative effect on the strength of the bonding layer. At Kuraray Noritake Dental Inc., we wanted to address the aforementioned issues and have developed a universal adhesive that is easy to apply and facilitates the establishing of thin, uniform bonding layers exhibiting high strength.

What are the indications of CLEARFIL™ Universal Bond Quick 2?

The new universal adhesive is indicated for bonding procedures in the context of creating direct restorations with light-cured composite, sealing of a prepared cavity or abutment tooth as a pretreatment for indirect restorations, treatment of exposed root surfaces and hypersensitive teeth, and also the intraoral repair of fractured restorations. Furthermore, the product is a suitable adhesive in post-cementation and core build-up procedures as well as in adhesive cementing of indirect restorations. When used in the context of the cementing of indirect restorations, the bonding to tooth structure of PANAVIA™ SA Cement Universal and of other manufacturers’ self-adhesive resin cements improves, leading to higher bond strengths.

What are the corresponding general benefits of CLEARFIL™ Universal Bond Quick AND CLEARFIL™ Universal Bond Quick 2?

The general benefits of both products are that they may be used with any etching procedure, plus the fact that there is no need to wait for the adhesive to penetrate the tooth structure after application. In addition, both products contain the original MDP monomer and the amide monomer, responsible for the formation of a thin and strong surface coating. Both products exhibit low technique sensitivity and are suitable for a wide range of indications. Finally, the adhesive monomers and fluoride offer extra protection to the underlying dentin.

Monomer image from the brochure

You mentioned the original MDP monomer as one of the essential components of the new adhesive and its predecessor. Is there a difference between this original MDP monomer and other MDP monomers available on the market?

Our MDP monomer is the only MDP monomer that is manufactured using the originally developed synthesis and purification process. Research has shown that the way MDP is manufactured has indeed an impact on the performance of the monomer itself1. While impurities and dimers detected in MDP monomers synthesized elsewhere negatively affected the immediate and aged micro-tensile bond strength in the in-vitro study, our MDP monomer shows high purity and more favourable test results.

Most universal adhesives need to be rubbed into the tooth structure extensively for 10 to 20 seconds. What did you do to eliminate the waiting time independent of the etching procedure, which led to an ultra-quick application procedure?

It is the amide monomer which is mainly responsible for an improved penetration speed into the tooth structure. The hydrophilicity of this monomer is much higher than the hydrophilicity of the HEMA monomer that is typically used. This provides for a better penetration into the moist dentin. The amide monomer’s polymerisation characteristics are better, and, following polymerisation, leads to higher stability in a wet environment due to the formation of a highly cross-linked polymer network. In combination with MDP, an efficient long-term performance will likely be achieved. For optimal outcomes, the adhesive is simply rubbed into the tooth structure as described in the IFU: “Apply BOND with a rubbing motion to the entire cavity wall with the applicator brush. No waiting time is required.”

What are the additional benefits that CLEARFIL™ Universal Bond Quick 2 has to offer?

First of all, we improved the viscosity and film thickness by optimizing the manufacturing method. The thin adhesive layer prevents pooling in the cavity, around abutments and along margins, creating a uniform bonding layer. Simply put, the new adhesive is applied thinly and spreads evenly. At the same time, the product offers high mechanical strength and excellent resistance to water sorption. Its bond strength is high in all etching modes and the new formulation allows for the product to be stored at room temperature.

Please explain the clinical benefit of an improved mechanical strength.

The risk of decreasing the film thickness lies in a possible decrease in the strength of the bonding layer which can lead to reduced bond durability. By introducing a new multifunctional urethane methacrylate monomer, we have been able to increase the strength. The effective advantage of the new bonding agent is that it can easily be used in small, difficult-to-access cavities or in cavities with complex morphology. The result is a thin yet strong adhesive layer that also allows for easy placement of any type of restoration.

How did you manage to improve the storage conditions?

Component stability was not an issue with CLEARFIL™ Universal Bond Quick. However, for a stable viscosity, it needed low-temperature storage. By optimizing the manufacturing method and decreasing the viscosity of CLEARFIL™ Universal Bond Quick 2, storage at room temperature became possible.

Was it difficult to integrate the new components and keep the existing benefits? How did you manage?

Integrating new components and removing others always means that the whole formulation needs to be rebalanced properly. This was particularly challenging for the multifunctional urethane methacrylate monomer we wanted to add. It improves the strength and hardness of the universal adhesive, but may affect adhesion depending on the amount of the compound in the formulation. Consequently, we needed to carefully find optimal balance, which took some time and required thorough testing, but in the end, we succeeded.

At the moment, the immediate dentin sealing technique is popular in indirect restoration procedures. What makes CLEARFIL™ Universal Bond Quick 2 suited for this technique?

Immediate dentin sealing is indeed a popular and useful technique that can result in significantly increased retention, reduced marginal leakage, improved bond strength, and less postoperative sensitivity. Using CLEARFIL™ Universal Bond Quick 2 in this context is beneficial as the procedure is quick, the resulting bonding layer is thin and strong, and the dentin is effectively protected.

Why should a dental practitioner switch to CLEARFIL™ Universal Bond Quick 2?

For users of CLEARFIL™ Universal Bond Quick, switching to CLEARFIL™ Universal Bond Quick 2 is worthwhile, as it offers additional advantages and improved performance while retaining the benefits of its predecessor. For users of other universal adhesives, the major benefit lies in the shortened application time: CLEARFIL™ Universal Bond Quick 2 is the only universal adhesive that can achieve a high bond strength and a high-strength bonding layer without any waiting time. In addition, it is suitable for a wide range of indications including core build-up procedures and cementation.

Thank you very much for these insights!

Case by Dr. Julien Molia

UNE NOUVELLE GÉNÉRATION DE FLUIDES

Heureusement, cela a changé : À ‚l‘instar de CLEARFIL MAJESTY™ ES Flow et CLEARFIL MAJESTY™ ES Flow Universal (tous deux de Kuraray Noritake Dental Inc.), plusieurs composites fluides de la dernière génération sont dotés de propriétés mécaniques équivalentes à celles de nombreuses alternatives compactes. Ainsi, le champ des indications est large. Par exemple, CLEARFIL MAJESTY™ ES Flow Universal présente selon la fabricant une charge élevée de 75 à 78 % en poids, une résistance à la flexion supérieure à 150 MPa et une résistance à la compression dépassant 370 MP. Grâce à sa résistance élevée, il constitue une solution fiable et permanente, qui convient même pour les zones avec tensions en flexion comme les surfaces occlusales des dents postérieures.

Ce composite fluide a toutefois encore plus à offrir : Il est disponible en deux niveaux de fluidité – LOW et SUPER LOW – pour répondre à un plus grand nombre de préférences personnelles et besoins individuels spécifiques à une indication et en seulement deux teintes (universal et universal dark). Ce concept de deux teintes offre l‘avantage d‘une sélection des teintes intuitive, même dans la zone antérieure, et est rendu possible par un mélange de technologies de correspondance des teintes comprenant la technologie optimisée de diffusion de la lumière et une translucidité semblable à celle de l‘émail.

L‘exemple de cas suivant dévoile comment CLEARFIL MAJESTY™ ES Flow Universal me facilite la vie dans les procédures de restauration postérieure.

EXEMPLE DE CAS

Ce patient s‘est présenté pour le remplacement de deux restaurations en amalgame dans les molaires mandibulaires droites (dents #46 et #47 selon la notation FDI) (Ill. 1). Afin de simplifier le remplissage et l‘adaptation aux parois de cavité, j‘ai décidé d‘utiliser CLEARFIL MAJESTY™ ES Flow Universal LOW en tant qu‘unique matériau restauratif. La position des dents à restaurer a rendu la sélection de teinte facile : La teinte U (universal) est conçue pour parfaitement fonctionner pour toutes les restaurations postérieures.

Les restaurations en amalgame ont été retirées et les caries excavées, avec conservation d‘autant de structure dentaire saine que possible (Ill. 2 et 3). Une technique de mordançage sélectif pour l‘émail a été choisie, suivie de l‘application d‘un adhésif universel (CLEARFIL™ Universal Bond Quick 2, Kuraray Noritake Dental Inc.). Puis, CLEARFIL MAJESTY™ ES Flow Universal en version LOW et dans la teinte sélectionnée a été appliqué dans les cavités (Ill. 4). Grâce au concept de seringue innovant, le composite f luide appliqué est littéralement sans vides. Suivant le mode d‘emploi du produit, l‘épaisseur de chaque couche ne dépassait pas les 2 millimètres afin d‘assurer une polymérisation complète (Ill. 5 et 6), ce qui a un impact déterminant sur la performance des restaurations finales sur le long terme. Chaque couche doit être polymérisée soigneusement pendant 10 à 20 secondes (en fonction de la lampe de polymérisation) avant l‘application de la couche suivante. Comme le montre l‘illustration 7, la faible fluidité du matériau sélectionné autorise un certain degré de modelage de la morphologie de surface occlusale. Quand il faut restaurer davantage de détails anatomiques, la variante plus solide SUPER LOW est envisageable. Il n‘a fallu que quelques secondes pour polir les restaurations en haute brillance (Ill. 8).

Ill. 1: Deux restaurations en amalgame à remplacer

Ill. 2: Situation après retrait des restaurations en amalgame existantes.

Ill. 3: Une tâche typique d‘amalgame est visible au fond de la plus grande cavité.

Ill. 4: Procédure de remplissage : application de la première couche de composite fluide.

Ill. 5: Seconde molaire déjà remplie, première molaire en attente d‘une autre couche de composite fluide.

Ill. 6: Remplissage terminé.

Ill. 7: Belle morphologie de surface dans laquelle s‘est fondue la teinte.

III. 8: Résultat du traitement après retrait de la digue en caoutchouc. Les restaurations se fondent joliment dans les dents alentour sur le plan de la teinte et du brillant.

ALTERNATIVE FACILE AUX COMPOSITES COMPACTS

En particulier dans les zones difficilement accessibles dans la bouche, l'utilisation d'un composite fluide avec des propriétés mécaniques bien équilibrées peut être une bonne alternative aux produits compacts. Les capacités avancées de correspondance des teintes, l'application littéralement sans vides, l'adaptation et le modelage aisés, ainsi que le polissage rapide simplifient réellement la vie du praticien dentaire.

CERABIEN™ MiLai in Daily Use

A tooth with crack lines, a characteristic round shape, age-related changes, or medication-induced discoloration — there’s no one-size-fits-all solution when it comes to all-ceramic anterior restorations, even when the porcelain system and production technique are defined.

To support technicians who wish to simplify their layering workflow using the micro-layering technique and CERABIEN™ MiLai — whether just getting started or looking to refine their process — we’ve collaborated with DT Dumitru Leahu to create a Chroma Map Catalogue featuring seven typical anterior restoration scenarios.

Each case example includes a detailed screenshot of the framework design, chroma maps outlining the planned steps, images of internal staining and micro-layering procedures, and the final restoration on the model. You’ll also find essential information about the selected framework material, target shade, and other relevant details.

We invite you to use the CERABIEN™ MiLai Catalogue as a step-by-step guide to success or simply as inspiration for individual cases. It offers a fast track to understanding the material’s optical properties and will make planning your next micro-layering case more intuitive. No need to start from scratch — instead, adapt what’s already there and gradually develop your own maps and techniques.

Quelles sont les indications de CLEARFIL™ Universal Bond Quick 2? 

Cet agent d‘adhésion est conçu pour une variété d‘applications cliniques: 

• Restaurations directes avec une résine composite photopolymérisée
• Scellement d‘une cavité ou dent pilier préparée en pré-traitement pour des restaurations indirectes

• Collage de restaurations indirectes

Pourquoi CLEARFIL™ Universal Bond Quick 2 est-il si performant? 

La clé de sa performance exceptionnelle réside dans sa technologie avancée d‘adhésion rapide (Advanced Rapid Bond Technology) qui consiste en trois ingrédients haute performance: 

• Monomère MDP original: Inventé par KURARAY CO., LTD., ce monomère fournit une force d‘adhésion inégalée à l‘hydroxyapatite et une vaste gamme d‘autres matériaux, dont l‘oxyde de zirconium.  Il assure une excellente adhésion qui est stable dans le temps. 
• Monomère d‘acide: Un monomère hautement hydrophile qui permet une pénétration rapide dans la structure dentaire, éliminant la nécessité d‘attente après l‘application. Pendant la polymérisation, il constitue un réseau hydrophobe réticulé stable pour une adhésion solide et durable.
• Monomère uréthane tétra méthacrylate (utma): Ce monomère multifonctionnel améliore la solidité de la couche d‘adhésion elle-même pour une meilleure résistance aux forces de rétraction tout en maintenant une couche adhésive fine et uniforme. 

Ces monomères forment conjointement la base de CLEARFIL™ Universal Bond Quick 2, vous offrant un adhésif polyvalent, rapide et fiable pour tous vos besoins en restauration.

Pourquoi choisir CLEARFIL™ Universal Bond Quick 2? 

CLEARFIL™ Universal Bond Quick 2 améliore l‘efficacité sans sacrifier la qualité. Sa technologie « Advanced Rapid Bond Technology » combine les monomères MDP, d‘amide et UTMA (uréthane tétra méthacrylate) pour créer une couche d‘adhésion solide et uniforme. Cela permet un étalement égal et une force d‘adhésion supérieure tant à l‘émail qu‘à la dentine. La formule de faible viscosité constitue un film fin et régulier pour réduire le risque de regroupement et améliorer la prévisibilité. 

Quelques autres atouts: 

• Application rapide et directe 
• Force d‘adhésion toujours durable
• Polyvalence adaptée à différentes techniques de restauration
• Risque réduit de regroupement et contamination
• Compatibilité avec les ciments de résine auto-adhésifs

• Auto-mordançage pour une approche plus moderne, rapide et efficace 
• Mordançage sélectif pour une force d‘adhésion supplémentaire à l‘émail 
• Mordançage total pour une approche conventionnelle. Il est disponible sous forme de flacon et de doses unitaires, répondant ainsi à différents besoins et assurant une utilisation facile à la demande.
