REALITY NOW rates brand-new PAVANIA™ Veneer LC

Just launched and already tested: REALITY RATINGS & REVIEWS has published a FirstLook evaluation of the brand-new PANAVIA™ Veneer LC, a purely light-cured resin cement for the permanent cementation of veneers and thin inlays and onlays. Based on laboratory testing, they conclude that “PANAVIA Veneer LC appears to be a worthy addition to the PANAVIA dynasty of cements.” The PANAVIA™ Veneer LC kit available in Europe consists of PANAVIA™ Veneer LC Paste, PANAVIA™ V5 Tooth Primer and CLEARFIL™ CERAMIC PRIMER PLUS.

During testing, the product features that are verifiable in a laboratory setting delivered no surprise: PANAVIA™ Veneer LC Paste is very well polishable with the polishing systems used, and the working time turned out to be exactly as long as specified by Kuraray Noritake Dental Inc. According to the evaluators, this working time is more than sufficient. While other possibly beneficial features – wear resistance and colour stability – were not put to a test, the evaluators were enthusiastic about the product’s handling properties. Their opinion: “The material itself has very nice handling properties, allowing easy seating of veneers with virtually no rebound. It is also not runny (flow is 5), but at the same time, it is not overly thick that you risk fracturing an ultrathin veneer. In addition, its consistency facilitates loading a veneer and cleaning the excess with minimal to no stickiness.”

Equipped with these favourable features, PANAVIA Veneer LC clearly has the potential to make your life easier during veneer cementation. Try-in pastes are available, the shade offering (four shades) is more than adequate and its close relatedness with PANAVIA™ V5 (which share technologies and system components) lets you use the product with confidence right from the start.

In the early 1990s, Kuraray introduced CLEARFIL™ LINER BOND 2, the first self-etching adhesive, to the world. Among the products that this system has led to is the award-winning CLEARFIL™ SE Protect, which was introduced in 2004 and remains highly valued by dental professionals across the world. By combining Kuraray Noritake Dental’s famed original MDP monomer with the antibacterial 12-methacryloyloxydodecylpyridinium bromide (MDPB) monomer, this self-etching adhesive is able to kill bacteria on contact. How is this possible? Let’s find out.

Pyridinium holds the key

The crucial element that provides CLEARFIL™ SE Protect with its antibacterial cavity cleansing ability is contained in the MDPB monomer. The pyridinium group in this monomer is positively charged, whereas the cell structures of bacteria are, generally speaking, negatively charged. This means that they are automatically attracted to the positively charged contact points of the MDPB monomer, causing these bacteria cell membranes to lose their electrical balance and be destroyed. This process—bacteriolysis—kills the bacteria.

The bactericidal mechanism of MDPB is presumed to be similar to that of the well-known antibacterial agent cetylpyridinium chloride, which is in many toothpastes and mouthwashes.

Certified biocompatibility

The MDPB monomer is immobilised during the polymerisation of the bonding and remains latently active without affecting the dental patient’s own cells. Unlike the situation when other cavity hygiene products are used, this process—patented by Kuraray Noritake Dental—does not have a negative impact on the bond strength and even ensures that there are no long-term cytotoxic effects on the patient’s own body cells such as odontoblasts. These results have been confirmed by the official biological evaluation for medical devices known as the ISO 10993 series.

Award-winning results with CLEARFIL™ SE Protect

With its antibacterial effect, high bond strength to enamel and dentine and long-term fluoride release, CLEARFIL™ SE Protect is reliable, versatile and future-proofed. This tried-and-tested two-step self-etching bonding system is fast and easy to use for direct restorations. For bonding indirect restorations and core build-ups, simply mix it with Kuraray Noritake Dental’s CLEARFIL™ DC Activator according to the instructions for use.

Thanks to its combination of MDP and MDPB monomers, CLEARFIL™ SE Protect leads to predictable, durable restorations—and it has received plenty of accolades from dental experts as a result. In 2022, this adhesive again received a Top Product Award in the Direct Restoratives, Bonding Agent: Self-Etch category from DENTAL ADVISOR. This was the fourth year in a row that it earned such recognition, and in addition, the 13 DENTAL ADVISOR consultants and editors gave CLEARFIL™ SE Protect a stunning 98% overall clinical rating.

PANAVIA Veneer LC inovatīvā tehnoloģija

Šajā "Highlights" tiek aprakstītas tehnoloģijas un tas, kā tas sekmē jaunā PANAVIA Veneer LC daudzās priekšrocības

Testimonial article by Dr. Troy Schmedding, USA

From PANAVIA™ EX to PANAVIA™ V5, Kuraray Noritake Dental Inc.‘s flagship product line of cements continues to evolve to offer reliable adhesion, enhanced ease of use, and superior esthetics.

Dentistry has certainly evolved in the years since Kuraray Noritake Dental Inc. developed the phosphate monomer MDP. But over the past 4 decades, it has rooted itself in restorative dentistry as the tried-and-true ingredient that clinicians rely on for strong adhesion to tooth structure as well as metals and zirconia. MDP is a key ingredient in the manufacturer’s flagship PANAVIA™ line of cements, which continues to evolve in line with a growing variety of indirect restorative materials from which to choose.

One example of this evolution is PANAVIA™ SA Cement Universal, one of the first true universal self-adhesive resin cements to hit the market. In addition to the original MDP monomer, it incorporates the LCSi monomer, a silane-based carbon chain in a dual-barrel system that forms a chemical bond with glass and ceramic materials.

“PANAVIA™ SA Cement Universal allows you to achieve a strong bond no matter which substrate is being used.”

- Troy Schmedding, DDS –

A STRONG BOND THAT’S SIMPLE TO CREATE

But all chemistry aside, what’s in it for the clinician? As dental educator and author Dr. Troy Schmedding points out, the key benefit of PANAVIA™ SA Cement Universal is eliminating the confusion over how to treat different substrates. This is because the material adheres to virtually every material without the need for a separate primer. “The plus side for the practitioner is that the confusion of ‚how do I condition zirconia‘ or ‚how do I condition glass ceramics‘ is no longer an issue because the paste formulation allows you to achieve a strong bond no matter which substrate is being used - whether it is the MDP monomer allowing strong adhesion to zirconia or the LCSi monomer forming a chemical bond with glass ceramics,” he shared.

DIALING UP THE AESTHETICS

Kuraray Noritake Dental Inc. considers PANAVIA™ V5 the most esthetic cement it has ever created. Available in 5 shades - White, Brown, Universal, Clear, and Opaque – it took researchers over 10 years to develop and features an anime-free catalyst that allows for superior colour stability and improved bond strength to dentin. And like its predecessors, PANAVIA™ V5 offers a simple cementation procedure that is compatible with all indications, from crown-and-bridge and implant abutments to ceramic inlays and laminate veneers.

“Kuraray Noritake Dental Inc. has an incredibly strong reputation in adhesive dentistry, so it should offer clinicians a lot of comfort and flexibility to partner with not only a reputable company, but one that continues to research and evolve their key products,” concluded Dr. Schmedding.

PRESENTATION OF A STUDY WITH ILLUSTRATIVE CASES

INTRODUCTION

In recent years, the application and advancement of digital technology in dentistry has made it possible to accomplish the fabrication of highly accurate prosthetic zirconia appliances that were difficult to mill using the previously available technology. In addition, thanks to advances in adhesive dentistry and the advent of cements that bond strongly to a diverse range of materials, cements have come into wide clinical use that can cope with the many types of materials used for the fabrication of prosthetic appliances.

At our hospital, we select the treatment method most suitable for each case by appropriately specifying various types of prosthetic appliance according to the status of each case. For example, we may specify zirconia prosthetic restorations fabricated by the CAD/CAM system, or silica-based ceramic prostheses, or those made of lithium disilicate glass, as the case dictates.

PANAVIA™ V5 is a resin cement system that bonds strongly to various types of prosthetic appliance, as well as to tooth structure. PANAVIA™ Veneer LC, a new resin cement system developed by Kuraray Noritake Dental Inc., has suitable characteristics for bonding laminate veneers, using two types of primer that can be used in common with PANAVIA™ V5. Here are some clinical examples of its advantages as a resin cement system used for laminate veneers restorations.

INOVATĪVA CIETĒŠANAS TEHNOLOĢIJA
PANAVIA™ Veneer LC nodrošina gaismā cietējošu cementu, apvienojot vairākas tehnoloģijas, nodrošinot augstāko iespējamo adhēziju.

VIRSMAS HERMETIZĀCIJA
Modificētā skāriencietināšanas tehnoloģija tiek izmantota, lai sasniegtu ilgāku apstrādes laiku, vienlaikus nodrošinot PANAVIA™ izslavēto adhēziju. PANAVIA™ Veneer LC, apvienojumā ar PANAVIA™ V5 Tooth Primer nodrošina gaismā cietējošajam cementam būtisku ķīmisko elementu. PANAVIA™ V5 Tooth Primer ir paškodinošs zoba audu (emaljas un dentīna) praimeris kas droši hermetizē zoba adhezīvo virsmu, kolīdz tas saskaras ar PANAVIA™ Veneer LC Paste. Vieglais, skāriencietējošais praimeris aktivizē tikai adhezīvās virsmas polimerizāciju un rada tūlītēju, noturīgu sasaisti ar emalju un dentīnu, taču neietekmē cementa cietēšanu un tādējādi - arī apstrādes laiku.

APSTRĀDES LAIKS
Cementēšanas procedūru laikā apstrādes laiku būtiski ietekmē vairāki ārējie faktori. PANAVIA™ Veneer LC tehnoloģijā šie faktori ir ņemti vērā.
Skāriencietināšanas tehnoloģija ļauj nekavējoties hermetizēt zoba saskarsmes virsmu, kas ir augstās adhēzijas noturības pamatā. Cementa
cietēšanas tehnoloģija nodrošina 200 sekunžu apstrādes laiku apkārtējā gaismā* pirms PVLC zaudē teicamo veidošanas elastību. Šo 200
sekunžu laikā varat ērti novietot un koriģēt (vairākus) venīrus. Gala polimerizācija notiek tad, kad tiek veikta gaismošana ar cietināšanas
lampu.
*Apkārtējā gaisma: aptuveni 8000 lux

JAUNAS PILDVIELAS
PANAVIA™ Veneer LC teicamo apstrādi sekmē nesen izstrādātās lodveida silīcija pildvielas un nanoklāsteru pildvielas (pildvielas noslodze: 66 wt%, 47 vol%). Cementa tiksotropisko īpašību dēļ nenotiek sēšanās vai nobīde. PANAVIA™ Veneer LC nodrošina kontrolētu uzklāšanu, cements paliek uzklāšanas vietā, taču labi plūst venīra(-u) novietošanas laikā.
Cementa viendabīguma un kārtas plānuma (≈ 8 μm) dēļ PANAVIA™ Veneer LC nodrošina plānu, vienmērīgu cementa slāni. Tādējādi tiek sekmēta viegla nosēdināšana bez traucējumiem. Līdztekus tam, tiek lietotas tikai nelielas, lodveida pildvielas (daļiņu izmērs: 0,05 μm – 8 μm), kas nodrošina īpaši estētiskas un gludas piemales, kā arī sekmē pulēšanu un spīduma noturību.

SILĪCIJA PILDVIELAS
Nesen izstrādātās cementa lodveida silīcija pildvielas nodrošina, ka cements paliek uzklāšanas vietā, taču labi plūst venīra nosēdināšanas laikā. Nodrošina vieglu uzlikšanu bez nobīdes vai sēšanās. Veicot uzklāšanu uz restaurācijas, sveķu cements nelīp pie uzklāšanas uzgaļa - šī īpašība tiek panākta, pastai pievienojot nanoklāsteru pildvielas.

Jaunie pildvielu veidi rada
teicamu gludumu, spīduma
noturību, kā arī vienkāršu
apstrādi.

VISKOZITĀTE UN TIKSOTROPIJA
Cementa viskozitāte ir būtiska, un tai jābūt pietiekamai zemai, lai novērstu restaurācijas plaisāšanu novietošanas laikā. Vienlaikus cements nedrīkst būt tikt plūstošs, lai tas notecētu uzklāšanas laikā un sēstos apstrādes laikā. Tā kā PANAVIA™ Veneer LC satur optimizētu pildvielas/sveķu maisījumu, tā viskozitāte mainās atkarībā no spiediena. Šo fenomenu dēvē par tiksotropiju. Pasta kļūst plūstošāka zem spiediena venīra novietošanas un koriģēšanas laikā. Spiedienam mazinoties, viskozitāte atjaunojas. PANAVIA™ Veneer LC tiksotropisko īpašību dēļ pastu var viegli izkliedēt un restaurācijas novietošanai ir vajadzīgs neliels spiediens, turklāt lieko materiālu ir viegli noņemt. Īsāk sakot: maksimāla kontrole.

Prosthodontic treatment concepts have evolved over the past decades. While some time ago, porcelain-fused-to-metal crowns and bridges were placed wherever a defect was too large for a direct restoration, the current trend is toward less invasive therapies with highly aesthetic, tooth-coloured materials.

These modern treatment concepts can lead to reliable outcomes when a high-performance resin cement system is used that establishes a durably strong bond to tooth structure on one side and the restoration on the other. The reason is that less invasive often means that restorations have minimal or no retentive elements and extremely thin walls, and a strong chemical bond is a mechanism that holds them in place over time. Depending on the type of restoration and area in the mouth, aesthetic properties of the cementation system are also extremely important, as the typically highly translucent, thin restorations tend to reveal the appearance of the structures underneath to a certain extent.

Universal cements

In the context of striving toward the streamlining of clinical procedures in restorative dentistry, several manufacturers have developed resins cements that work with fewer components and are suitable for a large number of indications. PANAVIA™ SA Cement Universal is a popular example. The self-adhesive, dual-cure resin cement is the only product of its category that works as a standalone solution even on glass ceramics (without the need for a separate primer).

The need for specialists

There are specific clinical situations, however, that require more working time than a dual-cure resin cement can offer. This is the case whenever multiple non-retentive restorations are to be placed simultaneously, a technique that is recommended for veneers. The greatest benefits of placing the thin and highly aesthetic restorations at once lie in the proper positioning of the restorations and in the minimized risk of contamination: When the veneers are placed one after the other, a slightly malpositioned and already fixed veneer might hinder proper positioning of the adjacent restorations and haemorrhage occurring in the context of excess cement removal or finishing of the margin might contaminate the working field. When all veneers are placed simultaneously, repositioning is possible, while excess removal and polishing are accomplished in a moment when blood and debris will no longer endanger the integrity of the restorations, which increases the security during the whole procedure. This task is best fulfilled by a light-curing veneer specialist.

Handling of a thin ceramic veneer.

Required properties of veneers cements

Undoubtedly, the key feature of a specialist resin cement system is a long working time sufficient for simultaneous cementation of multiple restorations. In addition, its consistency and handling properties are also important as they can help users overcome the challenge of accurate positioning and reduce the time and effort involved in veneer placement. And finally, the system needs to provide excellent bond strength over time and support long-lasting aesthetics, properties valuable for every kind of resin cement, but the latter being particularly important for thin restorations in the aesthetic zone. Luckily, PANAVIA™ Veneer LC offers all those features.

The system consists of PANAVIA™ V5 Tooth Primer that establishes a strong bond to enamel and dentin, PANAVIA™ Veneer LC Paste as the cement and the CLEARFIL™ CERAMIC PRIMER PLUS that has been part of PANAVIA™ V5 cementation system. The latter is responsible for a high bond strength to all types of restorative materials.

Mastering the working time challenge

The light-curing cement paste offers a long working time of 200 seconds* due to its excellent stability under ambient light. As a consequence, dental practitioners may place multiple veneers simultaneously without having to race against setting. Polymerization may be started whenever the user is ready for it. The one-component self-etching tooth primer (PANAVIA™ V5 Tooth Primer) does not contain any photo initiators and does not cure alone. When applied, it etches and penetrates into the tooth surface for 20 seconds and is ready to bond strongly to PANAVIA™ Veneer LC Paste. The integrated touch-cure technology is the key feature safeguarding a high bond strength to tooth structure without shortening the working time.

*Working time under ambient light on PANAVIA™ V5 Tooth Primer (8000 Lux): 200 seconds

Providing for precise placement

In order to streamline the clinical seating procedure from cement application to polishing, PANAVIA™ Veneer LC has been equipped with a set of well-balanced handling properties. Newly developed spherical silica fillers in the cement provide that it stays put where applied, but flows well when the veneer is seated on the tooth – for easy placement without drifting or sagging. During application across the intaglio surface, the resin cement does not stick to the application tip, a property achieved by the addition of nanocluster filler technology. The special design of the syringe’s application tip optimizes control over the amount of cement applied. Ans last but not least, excess cement may be easily removed in one piece using an explorer after a one-second tack-cure, while polishing of the margins is quickly accomplished.

Hiding the margins

Being extremely thin, highly translucent and mainly used to restore teeth in the exposed anterior region of the maxilla, veneers have to be placed with a cement that is and remains undetectable underneath the restoration and at its margins. PANAVIA™ Veneer LC is available in four highly aesthetic shades with matching try-in pastes, so that a precise shade match with the restoration can be achieved and verified in the patient’s mouth. Additional features contributing to undetectable margins are the resin cement’s flowability and low film thickness: They enable users to easily produce an evenly distributed, thin cement layer for aesthetic outcomes. For those afraid that coffee, tea, acidic drinks or constant tooth brushing might reveal the margins over time, there is good news as well: PANAVIA™ Veneer LC offers a high polish retention and colour stability over time. The well-balanced formulation and the touch-cure technology are responsible for this resistance to discolouration.

Trusted expertise

All these beneficial features make PANAVIA™ Veneer LC worth testing. Additional arguments are the fact that its primers are tried and tested components of the highly popular PANAVIA™ V5 system and that Kuraray Noritake Dental Inc. is a proven expert on adhesive products. It developed the original MDP Monomer in 1981 and introduced the first adhesive resin cement containing this monomer in 1983. Since then, the company has improved existing formulations and developed existing technologies that ultimately resulted in the current line-up of cementation solutions for every need and indication.

Excellent gloss retention is one of the properties providing for undetectable margins over time.

Kuraray Noritake Dental’s reputation as a pioneer in the field of dental adhesives is grounded in its development of the MDP monomer. Patented in 1981, the monomer was used two years later in the composite cement PANAVIA™ EX and has since formed the backbone of many other successful products. Now, the company has combined the original MDP monomer with hydrophilic amide monomers to create rapid bond technology that powers CLEARFIL™ Universal Bond Quick - a universal solution emblematic of Kuraray Noritake Dental’s history of success and commitment to innovation.

Advances in modern dental bonding technology have resulted in a reduction in the number of components needed for total-etching and self-etching processes. However, the basic handling of these adhesives has, by and large, changed surprisingly little. Many adhesives require a shaking of the bottle before usage, extensive rubbing of the liquid and/or waiting for a period of time. Often the application of multiple layers is needed. A reliance on slow penetrating monomers means that, for traditional one-bottle adhesives, bonding to the challenging dentine substrate is a slow and technique-sensitive process.

Through the integration of newly developed amide monomers, rapid bond technology provides CLEARFIL™ Universal Bond Quick with excellent hydrophilic properties and the ability to penetrate the wet dentine fast and effectively. There is no need to wait after the application for air-drying before proceeding - this delay has been eliminated - and a tight and long-lasting seal of the cavity is established after light-curing. Bonding with CLEARFIL™ Universal Bond Quick is easy and efficient and comes with predictable clinical outcomes, thanks to rapid bond technology.

Impressively low water sorption

One of the most important indicators of long-term success in dentine bonding is the level of water sorption in the bond’s organic matrix. A high rate of water sorption has been clinically linked to the ongoing physical deterioration of bonds, which may lead to the development of secondary caries. For this reason, we have chosen to keep the HEMA content as low as possible.

CLEARFIL™ Universal Bond Quick creates a highly cross-linked polymer network owing to the amide monomers used in rapid bond technology. As a result, it demonstrates a relatively low rate of water sorption, meaning that these cross-linked polymers are more stable in the long term.

Aesthetic, effective bonds

Rapid bond technology does not just provide a basis for long-lasting bonding excellence. The thin film layer (5–10 μm) of CLEARFIL™ Universal Bond Quick delivers restorations a clear aesthetic appeal, and its densely cross-linked polymer network reinforces the stability of this outer layer and provides resistance to marginal discoloration.

By combining Kuraray Noritake Dental’s original MDP monomer with hydrophilic amide monomers, rapid bond technology is truly the engine that powers CLEARFIL™ Universal Bond Quick.
