PRESENTATION OF A STUDY WITH ILLUSTRATIVE CASES

by Dr. Yohei Sato, DMD, PhD and Dr. Keisuke Ihara, CDT.

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.

NIEUWE VULSTOF
De uitstekende verwerking van PANAVIA™ Veneer LC is te danken aan de nieuw ontwikkelde sferische silicavuldeeltjes en de nanoclustervullers (vulstof gehalte: 66 wt%, 47 vol%). Dankzij de thixotropische eigenschappen van het cement zijn inzakken of wegvloeien niet meer aan de orde. PANAVIA™ Veneer LC staat garant voor een beheerste applicatie; het blijft op zijn plaats waar het wordt aangebracht, maar vloeit goed tijdens het plaatsen van de facing(s).
Dankzij de consistentie en lage filmdikte (≈ 8 μm) zorgt PANAVIA™ Veneer LC voor een dunne, gelijkmatig verdeelde cementlaag. Dit bevordert een gemakkelijke plaatsing, zonder verstoring. Bovendien liggen hoogesthetische Gladde cementranden binnen handbereik dankzij het gebruik van uitsluitend zeer kleine, sferische vulstofdeeltjes (deeltjesgrootte: 0,05 μm - 8 μm); tevens is afwerken gemakkelijker en wordt de gladheid behouden.

SILICAVULLERS
Mede door gebruik te maken van de nieuw ontwikkelde, sferische silicavuldeeltjes blijft het cement zitten waar het wordt aangebracht, maar vloeit het goed tijdens de plaatsing van de veneer. Gemakkelijke plaatsing, zonder wegvloeien en inzakken, is daardoor een feit. Tijdens het aanbrengen op het hechtoppervlak van het werkstuk plakt het composietcement niet aan de applicatietip; een eigenschap die te danken is aan de toevoeging van sferische nanoclustervullers aan de pasta.

Deze nieuwe vulstofdeeltjes resulteren in

een uitstekend gladheidsniveau en behoud

van glans evenals een gemakkelijke verwerking.

VISCOSITEIT & THIXOTROPIE
De viscositeit van een cement is essentieel en dient laag genoeg te zijn om breuk van de voorziening tijdens plaatsing te voorkomen. Tegelijkertijd mag het cement niet zo vloeibaar zijn dat het wegvloeit tijdens het plaatsen en de positionering van de restauratie.
Aangezien PANAVIA™ Veneer LC een geoptimaliseerd mengsel bevat van vulstoffen en kunsthars, verandert de viscositeit onder druk. Dit verschijnsel is thixotropie. De pasta wordt onder druk vloeibaarder tijdens de plaatsing en positionering van de veneer. Naarmate de druk afneemt, neemt de viscositeit toe. Dankzij de thixotropische eigenschap van PANAVIA™ Veneer LC laat de pasta zich gemakkelijk doseren, is er weinig druk nodig om de voorziening te plaatsen en is de overmaat gemakkelijk te verwijderen. Kortom, optimale controle.

Materialen met dezelfde viscositeit hoeven niet per se dezelfde thixotropie te hebben. Viscositeit wordt beïnvloed door temperatuur en druk. De mate en snelheid waarmee een materiaal bij verlaging van de druk terugkeert naar de originele viscositeit hangt af van de thixotropie van het materiaal.

INNOVATIEVE UITHARDINGSTECHNOLOGIE
PANAVIA™ Veneer LC is een lichtuithardend cement, dat verschillende technologieën combineert om u de hoogst mogelijke hechtsterkte te bieden.

SEALING VAN DE INTERFACE
Een verbeterde touchcure-technologie wordt gebruikt om een langere verwerkingstijd te realiseren met behoud van de hoge hechtsterkte waar PANAVIA™ om bekend staat. PANAVIA™ Veneer LC voegt, in combinatie met PANAVIA™ V5 Tooth Primer, een belangrijk chemisch element toe aan een lichtuithardend cement. PANAVIA™ V5 Tooth Primer is een zelfetsende primer voor tandweefsel (dentine en glazuur), die het tandoppervlak betrouwbaar verzegelt zodra deze in contact komt met PANAVIA™ Veneer LC Paste. Deze ‘milde’ touch-cure-reactie zet alleen de uitharding van de adhesieve interface in gang en brengt onmiddellijk een sterke hechting aan glazuur en dentine tot stand, echter zonder de uitharding van het cement - en daarmee de verwerkingstijd - te beïnvloeden.

VERWERKINGSTIJD
Tijdens cementeerprocedures wordt de verwerkingstijd beïnvloed door verschillende externe factoren. De technologie achter PANAVIA™ Veneer LC houdt rekening met die factoren. Dankzij de touch-cure-technologie wordt de tandinterface onmiddellijk verzegeld; de basis voor een hoge hechtsterkte. Dankzij de uithardingstechnologie profiteert u van een lange verwerkingstijd van 200 seconden onder omgevingslicht* voordat de ideale plasticiteit en dus de verwerkbaarheid van PANAVIA™ Veneer LC afneemt. Binnen dit tijdsbestek kunt u uw (meerdere) veneers comfortabel plaatsen en positioneren. De uiteindelijke polymerisatie vindt plaats tijdens de lichtuitharding, zodat het cement optimaal uithardt.

Fig. 1 The patient visited would like to have the a aesthetics
of the maxillary right and left lateral incisors improved.

Fig. 2 A silicon guide fabricated from a diagnostic wax model
was applied and the necessary clearances were determined.

Fig. 3 Since the lateral teeth are microdonts, the
preparation of each abutment was completed by simply
exposing a fresh enamel surface to be covered with
laminate veneers.

Fig. 4 A layer of porcelain was applied on the lithium
disilicate substrate, to complete the laminate veneers.

Fig. 5 The veneer was conditioned according to the

Case by Yohei Sato (DMD, PhD) and Keisuke Ihara (CDT)

Fig. 1 The patient was referred by an orthodontist. The main
complaints were improper aesthetics of the teeth due to dark
triangles betwen the teeth and incisal wear.

Fig. 2 On the basis of the pre-treatment diagnosis using
a mockup, the teeth were prepared, with keeping in mind
that the enamel should be preserved to the maximal extent
possible.

Fig. 3 A fixation retainer was present at the palatal side,
making it difficult to take coventional silicon impressions.
Therefore, an intraoral scanner was used.

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.

STATE-OF-THE-ART CURRENT ADHESIVES

Manufacturers have adopted an etch-and-rinse approach or a self-etch approach in the design of adhesives for bonding restorative materials to tooth structures, which differ in how these adhesives interact with dental hard tissues. Etch-and-rinse adhesives are offered as two- or three-step systems, depending on whether primer and bonding are separate or combined in a single bottle. Likewise, self-etch adhesives are available as one- or two-step systems. Etch-and-rinse adhesives are often preferred when large areas of enamel are still present, while self-etch adhesives provide more predictable bonds to dentin.

Despite current trends toward fewer and simpler application steps, one-step adhesive systems appear to be less predictable than multi-step etch-and-rinse and self-etch systems. Some manufacturers have recently introduced more versatile single-bottle “universal” or “multi-mode” adhesives that encompass self-etch chemistry but also enable the same adhesive to be used with phosphoric acid-etching in the etch-and-rinse mode. Some universal adhesives also incorporate silane primer for chemical bonding to silica-based ceramics, and methacryloyloxydecyl dihydrogen phosphate (MDP) for chemical bonding to zirconia-based ceramics. Because clinical studies on universal adhesives are short-term, they cannot be considered state-of-the-art in the context of evidence-based dentistry. Conversely, two-step mild, self- etch adhesives have been well-tested in clinical trials and represent the current state-of-the-art for bonding to dentin, with reduced incidence of postoperative sensitivity when compared to etch-and rinse adhesives.

DEVELOPMENT OF CONTEMPORARY ADHESIVES FROM A RESEARCHER’S PERSPECTIVE

The current thinking by researchers is that dentin bonding is not as durable as it was originally perceived. This lack of durability is attributed partially to secondary caries around restorative margins that are devoid of enamel and partially to the degradation of the adhesive joint. The latter may be caused by the hydrolysis of ester bonds in the adhesive component by salivary esterases, or by degradation of water-rich, resin-sparse regions of the hybrid layers by endogenous collagen-bound proteases such as matrix metalloproteinases (MMP) and cathepsin K, that are activated from their dormant preforms to active forms by the acidity of contemporary adhesives. These activated enzymes slowly degrade the denuded collagen matrix within hybrid layers, resulting in gradual loss of adhesion.

Much work has been done in developing therapeutic dental adhesives that are able to resist secondary caries and degradation of the adhesive joint. One of the most thoroughly studied antimicrobial resin monomers is the quaternary ammonium methacrylate developed by Kuraray known as methacryloyloxydodec ylpyridinium bromide (MDPB). This polymerizable resin monomer is incorporated in the two-step self-etch adhesive CLEARFIL™ SE Protect. Recent research has demonstrated that MDPB resin is also an effective inhibitor of both MMP and cysteine cathepsins, thereby providing a mechanism to increase the longevity of resin–dentin bonds by preventing collagen degradation. Indeed, an in-vitro and in-vivo study (Donmez, et al. J Dent Res. 2005;84:355-359) showed that resin-dentin bonds created with CLEARFIL™ SE Protect (aka, CLEARFIL™ Protect Bond) did not degrade after 1 year when compared with a similar self-etch adhesive that did not incorporate the MDPB resin monomer.

MOST COMMON CLINICAL APPLICATIONS OF CLEARFIL™ SE PROTECT

As a board-certified endodontist, the author uses CLEARFIL™ SE Protect as an antimicrobial adhesive to establish coronal seal after finishing root canal treatment to prevent reinfection of the peri-radicular tissues via coronal leakage through the filled root canals (Figure 1 and Figure 2). Another common use of CLEARFIL™ SE Protect is the restoration of the access cavity prepared through a zirconia-based full-coverage restoration. By taking advantage of the MDP component, the author feels more confident that he can bond to the zirconia with a resin composite without causing leakage along the composite-zirconia interface.

ADVANCED NEW FEATURES FOR MORE CONFIDENCE

Studies show that the risk of bacteria remaining in cavities tends to increase with smaller minimal intervention cavities (S. Imazato; Dent. Mater. J. 2009).

CLEARFIL™ SE Protect contains a new functional monomer MDPB, which exhibits an “Antibacterial Cavity Cleansing Effect” (Fig 3).

Fig 3. The bactericidal mechanism of MDPB is presumed to be similar to the well-known antibacterial agent CPC**, which is in many toothpastes and mouth rinses. **Cetyl pyridinium chloride

EXCEPTIONAL RESEARCH RESULTS

Increased durability of resin-dentin bonds

Recent research has demonstrated that MDPB is also an effective inhibitor of matrix metaloprotinases (MMP) that may deplete collagen.

The advantage of MDPB over chlorhexidine (CHX) is that it polymerizes with adhesive resins and cannot leach from the hybrid layer.
