“Simply apply and dry, and you’re done”: CLEARFIL™ CERAMIC PRIMER PLUS Combining ease of use and excellent viscosity, CLEARFIL™ CERAMIC PRIMER PLUS is a stable and universal prosthetic primer designed for all restorations. By incorporating Kuraray Noritake Dental’s original MDP monomer and a silane monomer, it is able to provide an enhanced adhesive surface for ceramics, hybrid ceramics, composites and even metals. CLEARFIL™ CERAMIC PRIMER PLUS is best used in conjunction with the adhesive resin cement PANAVIA™ V5 to ensure durable restorations. The key to CLEARFIL™ CERAMIC PRIMER PLUS’s performance is in the monomers it possesses. The MDP monomer strongly bonds to metals and zirconia, while the silane coupling agent MPS efficiently adheres to composites and all silica-based ceramics. “What makes CLEARFIL™ CERAMIC PRIMER PLUS different to other primers is its stability,” says Peter Schouten, Technical Manager at Kuraray Noritake Benelux. “Normally, activated silanes are very unstable. However, the well-balanced formula of CLEARFIL™ CERAMIC PRIMER PLUS provides it with a shelf life of three years after production, making it easy and predictable to use.” Procedural simplicity Every element of CLEARFIL™ CERAMIC PRIMER PLUS is designed to deliver maximal procedural simplicity. It is packaged in an easy-to-squeeze bottle that dispenses the solution easily and accurately. Whereas other similar products need to be left in place for one minute or more, this primer is immediately effective upon application. “CLEARFIL™ CERAMIC PRIMER PLUS benefits the dentists by offering a reliable primer for all materials, without being difficult to apply or use,” says Schouten. “From titanium to zirconia, from lithium disilicate to composite—simply apply and dry, and you're done.” PANAVIA™ V5 A resin cement with unrivalled procedural simplicity and predictability, PANAVIA™ V5 is a member of Kuraray Noritake Dental’s PANAVIA family. It sets a new standard for adhesion, allowing for self-cure dentine bond strengths equal to our gold-standard light-cure bonding agent, CLEARFIL SE BOND. PANAVIA™ V5 offers natural aesthetic stability in shading through its amine-free paste, which is available in five shades and has been scientifically proven to demonstrate a lower level of post-curing colour variance than amine-based cements. CLEARFIL™ CERAMIC PRIMER PLUS and PANAVIA™ V5 Providing strong bonding to not just hydroxyapatite, but to metals and zirconia as well, PANAVIA™ V5 is designed for use in conjunction with CLEARFIL™ CERAMIC PRIMER PLUS. The cementation procedure is efficient and effective: use PANAVIA V5 Tooth Primer for the pretreatment of the tooth, CLEARFIL™ CERAMIC PRIMER PLUS for the priming of the restoration, and PANAVIA™ V5 for the cementation.

PANAVIA™ family: Three options, all general cementation needs covered Is it possible to reduce the number of different cements used in a dental office? In most cases, it is. Kuraray Noritake Dental Inc. is convinced that one or two resin cement systems are usually enough to cover every indication and every need for general cementation. The selection of products may be different depending on personal preferences and the focus on specific dental treatments. That is why the company offers three high-quality resin cements, with which it is possible to meet the needs and desires of every dentist and patient. One product is available for those who would like to keep it as simple as possible while taking advantage of the multiple benefits resin cements offer over conventional cements. Another system is designed for those who demand highest possible bond strength and aesthetics. And finally, a light-curing system has been developed as a specialized solution for veneer cementation. In order to facilitate decision making, this article provides in-depth information on each of the three systems and their specific strengths. The everyday cement Keeping cementation simple and efficient is possible by minimizing the number of work steps and components and solving existing challenges. The self-adhesive dual-cure resin cement PANAVIA™ SA Cement Universal has been designed for these purposes. The challenge of removing sticky excess cement is overcome by a formulation that allows for very easy excess clean-up. Components are reduced as the product incorporates Kuraray Noritake Dental Inc.’s Original MDP Monomer and original silane coupling agent, the LCSi Monomer, for a strong and durable bond. While MDP establishes a strong and long-lasting chemical bond to enamel, dentin, metal and zirconia, LCSi is responsible for bonding to resin composite, porcelain and silica-type ceramics (like lithium disilicate), eliminating the need for separate primers. This means that a single component is needed, which streamlines the procedure, leading to time savings and a minimized potential for errors. Due to its properties, PANAVIA™ SA Cement Universal is ideal for everyday procedures such as the permanent cementation of crowns and bridges made of zirconia, lithium disilicate, hybrid ceramic or even metal. The strong and aesthetic allrounder For those who place importance on achieving the highest possible bond strength and aesthetics, PANAVIA™ V5 is the solution. The reliable dual-cure cementation system consisting of a tooth primer, a cement paste and a ceramic primer produces the highest bond strength and aesthetics from the PANAVIA™ cement range. Therefore, it is an excellent choice for a whole range of indirect restorations and for post-and-core procedures. As the well-aligned components are always combined and applied in the same way, standardization is supported, leading to predictable outcomes. The veneer specialist When fulfilling such demanding tasks as cementing veneers, every dental practitioner needs time. Especially when placing multiple veneers at once for the best aesthetic outcomes, having to race against the setting time is counterproductive. For this reason, Kuraray Noritake Dental Inc. developed PANAVIA™ Veneer LC, a light-curing resin cement system with an extended working time of 200 seconds* on the primer, which allows users to initiate polymerization whenever they are ready for it. PANAVIA™ Veneer LC also offers a well-aligned paste viscosity and consistency for easy dispensing and seating, and comes in four highly colour-stable shades for long-lasting aesthetics. Finally, the system provides for easy excess removal after tack-curing and an excellent bond strength over time. ** Working time: sensitivity to light (8000 lux, ISO 4049) Meeting expectations The three products mentioned are precisely what is needed to cover every personal preference and specific indication. They are based on Kuraray Noritake Dental Inc.’s long-standing expertise in the development of adhesive resin cements. The first product from the PANAVIA™ brand was introduced in the 1980s and since then, the company never stopped improving the portfolio by combining existing technologies like the original MDP Monomer with newly developed ones, such as the LCSi Monomer and the Touch Cure Technology. All this ultimately resulted in the current lean portfolio of easy-to-use and highly aesthetic resin cements that provide top-level bond strength. Dec 20, 2022
Innovation - Optimising bond quality with Katana Cleaner from Kuraray Noritake dental A strong and durable bond between the tooth and the restoration is a decisive factor influencing the long-term performance of dental restorations. The quality of the bond, however, is not only affected by the bonding agent or cementation solution used, but also by the condition of the bonding surface. For those who would like to ensure clean tooth and restoration surfaces in an easy way, Kuraray Noritake Dental has developed KATANA™ Cleaner, a universal cleaner with MDP salt and a pH of 4.5 for intra- and extra-oral application. It has been proven that proteins present in saliva and blood have a negative effect on the performance of dental adhesives. Especially in indirect procedures, however, it is impossible to keep the bonding surfaces free of oral fluids. At try-in at the latest, the prepared tooth and the restoration are contaminated and need to be cleaned. Rinsing with water does not have the desired effect, and even with many available cleaners, a certain amount of proteins are usually left on the surface. Tests show that by using KATANA™ Cleaner or by sandblasting, the desired high cleaning effect needed is obtained, without compromising bond strength. This is true for KATANA™ Zirconia restorations, while KATANA™ Cleaner also leads to the desired results on dentin and enamel – surfaces in the oral cavity for which sandblasting and most of the other cleaners are not indicated. The use of KATANA™ Cleaner offers yet another advantage: the cleaning procedure is extraordinarily simple, quick and neat. The universal cleaner comes in a bottle with an innovative flip-top cap, enabling single-handed dispensing onto the dish. It is then rubbed into the surface of the restoration and the prepared tooth structure or the abutment for ten seconds, rinsed with water and dried. Thanks to the high surface activity of MDP salt, these ten seconds are sufficient to remove the proteins on the substrate almost completely, creating conditions very similar to those found on a non-contaminated bonding surface. Subsequently, the selected bonding agent or cementation solution – e.g. PANAVIA™ V5 or PANAVIA™ SA Cement Universal – is applied according to the maufacturer’s usage instructions. The result is a strong long-lasting bond, which gives users a peace of mind. Pilot users who have already tested the product agree that KATANA™ Cleaner is the easy way to optimise bond quality and streamline any adhesive procedure. Feb 19, 2020
Clinical Report about PANAVIA Veneer LC 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. Sep 8, 2022
Performance and practicality Case by A/Prof Alan Yap, BDS (Syd), MDSc Hons (Pros)(Syd), FAANZP Since 1983 PANAVIA™ by Kuraray Noritake Dental Inc. has been the gold standard for dental cements throughout the world. Their latest cement, PANAVIA™ Veneer LC, sets a new standard for porcelain veneer cements through incredible performance and ease of use. The following clinical case demonstrates the use of PANAVIA™ Veneer LC. A 31-year-old female (Fig. 1) was referred for porcelain veneers to replace lost tooth structure and to improve aesthetics. The patient exhibited moderate attrition of her anterior and bicuspid teeth (Fig. 2), the result of nocturnal bruxism and a tendency to an edge-to-edge occlusion. She had a Class I malocclusion on a Skeletal Class I tending III base with the right maxillary canine in cross-bite. The treatment plan included orthodontic treatment, porcelain veneers, and an occlusal splint. Fig. 1 Fig. 2 Orthodontic treatment (by Dr Nour Tarraf) included full-fixed appliances with TADs and IPR of mandibular anteriors, and arch retractions to reduce protrusion (Fig. 3, post-orthodontic treatment). A preliminary digital design (Fig. 4) was performed to guide the diagnostic wax-up and a digital mock-up (Fig. 5) was utilised to verify the diagnostic wax-up prior to carrying out the intra-oral mock-up. The patient was unable to afford the restoration of the maxillary bicuspids until a later stage so the reconstruction was limited to the maxillary anterior teeth. Fig. 3 Fig. 4 Fig. 5 Using the diagnostic wax-up, silicone keys were fabricated to guide tooth preparations. Orthodontic treatment allowed prosthetic treatment to be additive in design which meant that tooth preparations could be conservative. Labial reductions were limited to 0.3 mm and incisal reductions were performed only where needed to create an incisal butt joint for the veneer (Fig. 6). Minimal preparations allowed the veneers to be bonded almost entirely to enamel, which is important for the long-term survival of porcelain veneers (Ref 1). There was no need to significantly mask the colour of the cervical region of the tooth and non-carious cervical lesions were absent, so fine chamfer margins were prepared at equi-gingival level. Fig. 6 Splinted provisional veneers (Fig. 7) were fabricated using bisacryl ensuring sufficient interdental space to allow hygiene access for small interdental brushes. The labial surface of the provisional veneers were glazed with a unfilled resin and cemented using the spot-etch technique, ensuring all excess flowable composite was removed prior to curing (Fig. 8). Twice daily interdental cleaning of the provisional veneers and thorough brushing of labial margins during the provisional phase maintained soft tissue health, important for the try-in and cementation of the definitive veneers. Fig. 7 Fig. 8 A dry try-in of the definitive veneers was performed to check the fit of the veneers and a wet try-in was performed using try-in paste to assess aesthetics. The PANAVIA™ Try-in pastes accurately mimic the cement shades. Four useful shades are available (Fig. 9). The White and Brown shades are useful to correct small discrepancies in shade requiring subtle increases or decreases in shade value respectively. Conveniently the try-in pastes are the same as the PANAVIA™ V5 range of try-in pastes (excluding opaque). Following the try-in procedure the teeth were isolated using rubber dam and the floss ligature technique. KATANA™ Cleaner (Fig. 10) was used to clean the veneers prior to silanating with CLEARFIL™ CERAMIC PRIMER PLUS (Fig. 11). Fig. 9 Fig. 10 Fig. 11 Veneers that have not been pre-etched should be etched with hydrofluoric acid prior to silanization. The use of the ProsMate™ Baton allows the cleaning, etching and silanization of all veneers simultaneously (Fig. 12). The veneers are arranged systematically on the ProsMate™ Tray ready for the cementation procedure (Fig. 13). Tooth surfaces were pre-treated with phosphoric acid (K-ETCHANT Syringe) and PANAVIA™ V5 Tooth Primer (Fig. 14). Fig. 12 Fig. 13 Fig. 14 The newly designed cement applicator tip reduces air bubbles and the wide 16-gauge tip (Fig. 15) allows light and easy control of cement extrusion while also providing efficient wide coverage during application. PANAVIA™ Veneer LC has excellent handling because of its ideal paste consistency. It is non-sticky and its viscosity prevents the cement from flowing beyond the veneer margins until the veneer is seated. It is not runny or stringy. Furthermore its thixotropic properties results in lower film thickness during seating of the veneer. These excellent handling properties are due to the development of new filler technology which consists of spherical silica and nano cluster fillers (Fig. 16). The “touch-cure” mechanism of PANAVIA™ V5 Tooth Primer importantly seals the bonding interface while the extended working time and stability of the cement under ambient light allows the simultaneous cementation of multiple veneers. In this case all six lithium disilicate veneers (technical work by Yugo Hatai) were cemented simultaneously with PANAVIA™ Veneer LC Paste (Clear). Fig. 15 Fig. 16 Tack-curing each veneer for one second allowed smooth and easy bulk removal of excess cement with an explorer (Fig. 17). Remaining excess of uncured paste was removed with brushes. Final curing was performed by light curing lingual and labial surfaces. Fig. 17 The optical characteristics of PANAVIA™ Veneer LC, use of fine chamfer margins, and well-fitting translucent restorations produces a gradual and smooth transition of colour from tooth to veneer where margins disappear and soft tissues respond in a healthy way (Fig. 18). The color stability, excellent abrasion resistance and high gloss durability of PANAVIA™ Veneer LC preserves integrity and aesthetics at the margins over the long term. The extraordinary bond strength of PANAVIA™ products, so familiar to our profession over the last 20 years, is still second to none (Fig. 19).

Choose PANAVIA™ Veneer LC and veneer cementation becomes a success 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. Aug 23, 2022
Optimizing functional and esthetic parameters in veneer cementation By Dr. Clarence Tam, HBSC, DDS, AAACD, FIADFE The use of both porcelain veneers to improve and restore the shape, shade and visual position of anterior teeth is a common technique in esthetic dentistry. The biomimetic aim in the restoration of teeth is not only the cosmetic domain, but also functional considerations. It is critical to note that the intact enamel shell of the palatal and facial walls with respect to anterior teeth are responsible for its innate flexural resistance. When dental structure has been violated by endodontic access, caries and/or trauma, every effort must be made to preserve the residual structure and strive to restore or exceed the baseline performance levels of a virgin tooth. BACKGROUND A 55 year old ASA II female with a medical history significant only for controlled hypertension presented to the practice for teeth whitening. It was foreseen that dental bleaching would not have an effect on the shade of a pre-existing porcelain veneer on tooth 1.2, and that this would need to be retreated following the procedure especially if the shade value changes were significant. The patient started with a baseline shade of VITA* 1M1:2M1; 50:50 ratio in the upper anterior region and 1M1 in the lower anterior region. Following a nightguard bleaching protocol with 10% carbamide peroxide worn overnight for 3-4 weeks, the patient succeeded in achieving a VITA* 0M3 shade in both upper and lower arches. As a result, there was a significant value discrepancy between the veneered tooth 1.2 and the adjacent teeth, and also increased chroma noted on the contralateral tooth 2.2 due to a facially-involved Class III composite restoration. This latter tooth also did not match the contralateral tooth in dimension and thus the decision was made to treat both lateral incisors with bonded lithium disilicate laminate veneers. The canine adjacent (2.3) featured localized mild to moderate cusp tip attrition, but the patient did not want to address this until following the currently-discussed veneers were placed. The goal of smile design at this stage is to ultimately establish bilateral harmony with the view to place an additional indirect restoration restoring the facial volume and cusp tip deficiency of tooth 2.3 in the near future. PROCEDURE A digital smile design protocol was not required for the initial intention, which was individual treatment of the lateral incisors, as slight variation is permitted in this tooth type, being a personality and gender marker of the smile. Prior to anesthesia, the target shade was selected using retracted photos featuring both polarized and unpolarized selections. The photographs were prepared for digital shade calibration by taking reference views with an 18% neutral gray white balance card (Fig. 1). Fig. 1. Reference photograph taken with a 18% neutral gray card. The basic body shade was VITA* 0M2 with an ingot shade of BL2. The patient was anesthetized using 1.5 carpules of a 2% Lignocaine solution with 1:100,000 epinephrine before affixing a rubber dam in a split dam orientation. The veneer on tooth 1.2 was sectioned and removed from tooth 1.2 and a minimally-invasive veneer preparation completed on tooth 2.2 (Fig. 2). Partial replacement of the old composite resin restoration was completed on the mesioincisobuccopalatal aspect of tooth 12 with the intact segment maintained. Adhesion to old composite was achieved using both micro particle abrasion and a silane coupling agent (CLEARFIL™ CERAMIC PRIMER PLUS, Kuraray Noritake Dental Inc.). Margins were refined and retraction cords soaked in an aluminum chloride solution and packed. Preparation stump shades were recorded. Final impressions were taken using both light and heavy body polyvinylsiloxane in a metal tray. The patient was provisionalized and sent away with instructions to verify the shade at the laboratory at the bisque bake stage. The models prepared by the laboratory verify the minimally-invasive nature of the case. Fig. 2. Veneer preparation tooth 1.2, 2.2. On receipt of the case, the patient was anesthetized and the provisionals removed. The preparations were debrided and prepared for bonding by abrading the surfaces using a 27 micron aluminum oxide powder at 30-40 psi. The veneers were assessed using a clear glycerin try-in paste (PANAVIA™ V5 Try-in Paste Clear, Kuraray Noritake Dental Inc.). Retraction cords were packed and the intaglio surface of the restorations treated using a 5% hydrofluoric acid for 20 seconds prior to application of a 10-MDP-containing silane coupling agent (CLEARFIL™ CERAMIC PRIMER PLUS, Kuraray Noritake Dental Inc.) (Fig. 3). The tooth surface was etched using 33% orthophosphoric acid for 20 seconds and rinsed. A 10-MDP-containing primer was applied to the tooth (PANAVIA™ V5 Tooth Primer, Kuraray Noritake Dental Inc.) (Fig. 4) and air dried as per manufacturer’s instructions. Veneer cement was loaded (PANAVIA™ Veneer LC Paste Clear, Kuraray Noritake Dental Inc.) (Fig. 5) and the veneer seated. The excess cement featured a non-slumpy character and maintained the veneer well in place during all margin verification exercises prior to a 1 second tack cure (Fig. 6). Fig. 3.

Note the viscous, non-slumpy nature of the cement, which allows for ease of removal under both wet and gel-phase options. The cement was rendered into a gel state, which facilitated “clump” or en masse removal of cement with minimal cleanup required (Fig. 7). The margins were coated using a clear glycerin gel prior to final curing to eliminate the oxygen inhibition layer (Fig. 8). Fig. 7. Excess cement removal after tack curing for 1 second. Fig. 8. Final curing of veneers from both palatal and facial aspects simultaneously. The margins were finished and polished to high shine and the occlusion of the restorations verified as conformative. The post-operative views show excellent esthetic marginal integration (Fig. 9). Fig. 9. Post-operative esthetic integration of veneers on 1.2 and 2.2. On polarized photograph reassessment, the restorations are well-integrated into the new smile esthetically and functionally (Fig. 10), now awaiting esthetic augmentation of tooth 2.3 to match the contralateral canine. FINAL SITUATION Fig. 10. Final result with polarized photography on reassessment. RATIONALE FOR MATERIAL SELECTION Porcelain is often the chosen material for prosthetic dental veneers due to its innate stiffness in thin cross section, ability to modify and transmit light for optimal internal refraction and its bondability by way of adhesive protocols to composite resin. This trifecta allows for a maximal preservation of residual tooth structure whilst bolstering its physical function relative to flexural performance1. The elastic modulus of a tooth can be restored to 96% of its control virgin value if the facial enamel is replaced with a bonded porcelain laminate veneer2. The elastic modulus of lithium disilicate is 94 GPa whereas that of intact enamel is 84 GPa. The elastic modulus of dentin has been found to range from 10-25 GPa, whereas that of the hybrid layer can vary widely, indeed from 7.5 GPa to 13.5 GPa in a study by Pongprueska et al3. This low flexural resistance range reflects that of deep dentin and not that of superficial dentin, which does not reflect an ideal situation where a laminate veneer is bonded in as much enamel as possible, or in the worst case to superficial dentin. Maximal flexural strength of the hybrid layer is invaluable from a biomimetic standpoint. PANAVIA™ V5 Tooth Primer (Kuraray Noritake Dental Inc.) incorporates the use of the original 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) monomer, which elicits a pattern of stable calcium-phosphate nanolayering known as Superdentin, an acid-base resistant zone that is about 600x more insoluble than the monomer 4-MET, which is found in many other adhesives. Indeed, PANAVIA™ V5 Tooth Primer is used solely in conjunction with Kuraray Noritake Dental Inc. PANAVIA™ V5 cement and PANAVIA™ Veneer LC which both allow the primer to act as a bond without the need to cure the layer prior to cementation of the indirect restoration due to its dual cure potential when married together. If a bonding agent would be preferred, CLEARFIL™ Universal Bond Quick (Kuraray Noritake Dental Inc.), a multi-modal adhesive that also contains the essential amide monomer and 10-MDP components created by Kuraray Noritake Dental Inc., can be used. Of note, CLEARFIL™ Universal Bond Quick features exceptional flexural strength due to the accentuated cross-linking during polymerization afforded by the amide monomers, on the order of 120 MPa by itself4. PANAVIA™ Veneer LC is a cement system that features cutting edge technology that provides excellent esthetics and adhesive stability of your indirect restorations, whilst allowing a stress free workflow. It is a cement system that is a game changer; one that allows you to restore confidence in the patient, strength in the tooth-restoration interface, and bolsters your clinical confidence in the delivery of biomimetic excellence.

PANAVIA™ Veneer LC: cement for the most challenging esthetic conditions AWARD WINNING PRODUCT DENTAL ADVISOR, which annually honors as Top Product or Preferred Products items deemed by the publication’s consultants to deliver the best practice-based performance in their categories, singled out PANAVIA™ Veneer LC for a Research Award in the Lab Performer: Veneer Cement category in its January/February 2024 edition. This particular award is given to products that performed exceptionally well when tested independently in Dental Advisor Laboratories. ABOUT THE PRODUCT 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 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. WHAT WAS RESEARCHED The basis of PANAVIA™ Veneer LC’s selection this year was research that compared three esthetic veneer cements, including PANAVIA™ Veneer LC, for bond strength, adhesion properties, gloss retention, and wear resistance. 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 multiple substrates, the cements were subjected to six months of artificial aging to dentin, enamel, IPS e.max CAD, and Zirconia using thermocycling. To test wear resistance after toothbrush erosion, 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. EVALUATION RESULTS 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, “Due to its excellent properties, PANAVIA™ Veneer LC Paste can meet the most challenging esthetic conditions of veneer cementation.” COMPLETE REPORT Would you like to read the full report1 shared by Dental Advisor?
