When art meets technology;
Logical evolution of design and techniques: Microlayering with Kuraray Noritake new porcelains. 

DANIEL RONDONI
Born in Savona in 1961, he lives and works in his hometown where he has been the manager and director of his own laboratory since 1982.

Vahvalla ja kestävällä sidoksella hampaan ja restauraation välissä on ratkaiseva merkitys hoitotuloksen pitkäikäisyyden kannalta. Sidoksen laatuun ei kuitenkaan vaikuta vain käytetty sidosaine tai sementti, vaan myös itse sidostettava pinta. Haluttaessa varmistaa puhtaat sidostettavat pinnat niin hampaassa kuin restauraatiossa Kuraray Noritake Dentalin kehittämä KATANA™ Cleaner on oiva ratkaisu – universaali puhdistin MDP-suolalla ja 4,5 pH:lla suun sisäpuoliseen ja ulkopuoliseen käyttöön.

On todistettu, että syljen ja veren proteiinit vaikuttavat sidoksen lujuuteen heikentävästi. Erityisissä epäsuorissa toimenpiteissä on mahdotonta pitää sidostettavia pintoja puhtaina suun nesteistä. Viimeistään sovituksen aikana preparoitu hammas ja restauraatio kontaminoituvat ja ne tulee puhdistaa. Vedellä huuhtelu ei tuota haluttua vaikutusta eikä useat saatavilla olevat puhdisteetkaan , vaan tietty määrä proteiineja jää yleensä pintaan. Testit osoittavat, että käyttämällä KATANA™ Cleaneriä tai hiekkapuhallusta, saavutetaan tarvittava tehokas puhdistustulos vaarantamatta sidoksen lujuutta. Tämä pätee KATANA™ Zirconia -restauraatioihin, mutta KATANA™ Cleaner toimii myös dentiinille ja kiilteelle, joille hiekkapuhallus ja useimmat muut puhdistimet eivät ole indikoidut.

KATANA™ Cleanerin käyttö tarjoaa vielä yhden lisäedun: puhdistustoimenpide on poikkeuksellisen yksinkertainen, nopea ja siisti. Universaalin puhdistimen pullon innovatiivinen korkki mahdollistaa yhdellä kädellä avauksen ja annostelun vientimaljaan. Sen jälkeen se hierotaan restauraatiolle ja preparoidulle hammasrakenteelle tai nastalle kymmenen sekunnin ajan, huuhdellaan vedellä ja kuivataan. MDP-suolan korkean pinta-aktiivisuuden ansiosta nämä kymmenen sekuntia riittävät poistamaan proteiinit pinnoilta melkein täysin luoden olosuhteet, jotka ovat hyvin samanlaiset kuin ei-kontaminoituneilla sidospinnoilla. Tämän jälkeen valittu sidosaine tai sementti – esim. PANAVIA™ V5 tai PANAVIA™ SA Cement Universal – applikoidaan valmistajan käyttöohjeiden mukaisesti.

Tuloksena on vahva, pitkäkestoinen ja luotettava sidos. Pilottikäyttäjät, jotka ovat jo testanneet tuotetta, ovat yhtä mieltä, että KATANA™ Cleaner tarjoaa helpon tavan optimoida sidoksen laatu ja selkeyttää sidostukseen liittyvät toimenpiteet.

CLEARFIL MAJESTY^TM ES Flow -yhdistelmämuovista, jonka Dental Advisor on palkinnut viitenä vuonna peräkkäin, on nyt saatavana kolmena eri juoksevuutena, mikä tekee tuotteesta aiempaa monikäyttöisemmän. Hammashoidon ammattilaiset pystyvät saavuttamaan halutun lopputuloksen entistä nopeammin ja helpommin.

Yleiskäyttöinen juokseva CLEARFIL MAJESTY^TM ES Flow -yhdistelmämuovi on uusi innovaatio, jonka on kehittänyt Kuraray Noritake Dental –yritys, joka tunnetaan maailmanlaajuisesti asiantuntemuksestaan restauraatiomateriaalien alalla. Kuraray Noritake Dental on kehittänyt suurta suosiota saavuttaneen CLEARFIL MAJESTY^TM Flow -yhdistelmämuovin pohjalta uuden korkealaatuisen tuotteen, jolla soveltuu täytteisiin, korjauksiin ja sementointiin. Kaikkien näiden ominaisuuksien yhdistäminen yhteen tuotteeseen tekee muut yhdistelmämuovit tarpeettomiksi.

Kuraray Noritake Dentalin kehittämän silanointitekniikan ansiosta CLEARFIL MAJESTY^TM ES FLOW -yhdistelmämuovi s sekä submikronifillereitä että nanoklusterifillereitä. Tämän ansiosta CLEARFIL MAJESTY^TM ES FLOWn filleripitoisuus on korkea, mutta juoksevuus silti hyvä. Tuotteen esteettisyys on erinomainen, sillä nanoklusterifillerit hajottavat valoa niin, että yhdistelmämuovi sulautuu saumattomasti ympäröivään hammasrakenteeseen.

CLEARFIL MAJESTY^TM ES FLOW -yhdistelmämuovin etuja:

• Varma toimivuus ja helppo käsittely: annostelu suoraan ruiskusta, helppo ja nopea kiillotus
• Kestävä: yhdistelmämuovin taivutuslujuus on 150 MPa ja puristuslujuus 373 MPa
• Moniin eri indikaatioihin: kaikki kaviteettiluokat, korjaukset ja sementoinnit
• Estetiikka: valon sirotusteknologian ansiosta väri sulautuu erinomaisesti ympäristöön

AINOA YHDISTELMÄMUOVI, JONKA HAMMASLÄÄKÄRI TARVITSEE.

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.

Get to know the CLEARFIL MAJESTY family

Kuraray Noritake Dental is proud to present the CLEARFIL MAJESTY family, a series of universal composites designed for reliable, natural-looking restorations. With its brightness-based shade system for direct composites, CLEARFIL MAJESTY is another symbol of our company’s dedication to research and development, promising ease of use and reproducibility for the dentist.

CLEARFIL MAJESTY ES-2 Classic and Premium

A universal nano-hybrid composite resin with a high refractive matrix, CLEARFIL MAJESTY ES-2 Classic was introduced to the world at the 2013 International Dental Show in Germany. It combines easy sculpting with a predictable and aesthetic finish for a composite that will benefit both the dentist and the patient. With 15 precisely matched VITA shades and some special shades for whitening, it is suitable for a range of anterior and posterior restorations, including all cavity classes, composite facings, intra-oral repairs of fractured crowns and bridges, and corrections of tooth positioning and shape. CLEARFIL MAJESTY ES-2 Classic uses Kuraray Noritake Dental’s Light Diffusion (LD) technology to accurately replicate the diffusive properties of dentine. This feature means that restorations blend in with the existing tooth structure, rendering them virtually undetectable.

Through its fixed shade combinations of dentine and enamel, CLEARFIL MAJESTY ES-2 Premium is able to cover three VITA shades at once, making natural-looking restorations easily achievable. This dual-layer aspect means that there is an optimal built-in pairing of enamel translucency and dentine opacity, eliminating the need for any complicated shading schemes. By also incorporating LD technology, CLEARFIL MAJESTY ES-2 Premium is able to adjust the colour saturation and tint to that of the neighbouring tooth issue automatically. The small particle size of its proprietary nano-filled composite ensures easy polishing with a durable gloss, promising an aesthetic and seamless restoration.

CLEARFIL MAJESTY ES Flow

A light-curing universal, flowable composite, CLEARFIL MAJESTY ES Flow combines easy handling, high polishability and impressive mechanical strength to provide a material for all cavity classes. Thanks to Kuraray Noritake Dental’s silane technology, its submicron filler particles adhere reliably to the resin and maintain long-term stability. These small yet durable particles allow restorations made with CLEARFIL MAJESTY ES Flow to keep their high level of enamel gloss over time, with special cluster fillers providing a light diffusion property similar to that of natural teeth. The gloss itself is remarkably simple to achieve: just wipe the cured resin with an ethanol-moistened gauze or cotton roll to produce a smooth surface.

CLEARFIL MAJESTY ES Flow’s excellent handling characteristics allow for better sculpting. The material does not stick to the needle tip or to any instruments, only adhering to the area to which it is applied, and the proprietary design of the syringe itself minimises air bubbles when dispensing. A truly universal composite, CLEARFIL MAJESTY ES Flow allows dentists to create highly aesthetic restorations with ease.

Kuraray Noritake Dental concludes a patent license agreement with 3M In March 2018, Kuraray Noritake Dental Inc. (President: Kiyoyuki Arikawa), with its Head Office in Chiyoda-ku, Tokyo, concluded a license agreement with the 3M Company, whose Head Office is in Saint Paul, Minnesota, USA. The agreement concerns a patented method for producing multilayered ceramics, European patent No. 2024300, held by Kuraray Noritake Dental Inc.

Summary of Kuraray Noritake Dental Inc. ceramic business

Kuraray Noritake Dental Inc. launched the zirconia disc that has been commercialized through the use of our layered ceramic production method in 2012. The product has multi-layered structure with four different colored zirconia powders that feature a smooth transition of color gradation between layers. We took advantage of the dental ceramic coloring technology we had accumulated through the development of porcelains. Success was achieved in controlling the shrinkage of the layers by optimizing the amounts of pigments added, thereby achieving great accuracy in terms of adaptation. In 2015, we also launched a new series zirconia which has the high degree of translucency of natural tooth enamel and is suitable for the esthetic restorations of anterior teeth. In January 2018, zirconia block joined the zirconia family as our new solution for the fabrication of zirconia restorations. This new product achieves a well-balanced combination of appropriate mechanical properties and good esthetics with a short baking time. Kuraray Noritake Dental Inc. is committed to developing new dental materials that contribute to the dental industry. Our products have become even more competitive on the global market because of our intense pursuit of technological innovation.

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.
