OPTIMIZIRANO RUKOVANJE
Je li moguće skratiti vrijeme i smanjiti trud koji su potrebni za postavljanje ljuskica pomoću cementa koji podržava homogeno nanošenje cementa, jednostavno pozicioniranje ljuskica i uklanjanje viška te brzo poliranje? PANAVIATM Veneer LC nudi sve potrebne značajke i visoku kontrolu zahvaljujući posebno dizajniranom vrhu za nanošenje.
NELJEPLJIVOST
Smolasti cement nudi izvrsnu konzistenciju, idealnu za jednostavno i sigurno nanošenje preko površine s dubokim urezima jer se ne lijepi za nastavak za nanošenje zahvaljujući tehnologiji nanoklasterskog punila.
IDEALNA KONZISTENCIJA
Novorazvijenim sfernim punilima od silicija u cementu, osigurava se njegovo ostajanje na mjestu nanošenja, ali uz dobro tečenje tokom namještanja ljuskice na zub – za jednostavno postavljanje bez pomicanja ili spuštanja.
JEDNOSTAVNO UKLANJANJE VIŠKA
Višak cementa može se ukloniti u jednom komadu strugačem nakon stvrdnjavanja svjetlom u trajanju od jedne sekunde.
VISOKA ESTETIKA
Zbog njihove općenito minimalne debljine i visoke translucencije, na estetski izgled ljuskica jako utječe boja cementa. Stoga je ključno koristiti smolasti cement postojane boje i koji stvara rubove koji ostaju nevidljivi tijekom vremena. PANAVIA Veneer LC ispunjava te zadatke.
OTPORNOST NA PROMJENU BOJE
Visoka postojanost boje vjerojatno je najvažnija značajka zaslužna za dugotrajnu estetiku, koju osiguravaju dobro uravnotežena formulacija i tehnologija stvrdnjavanja na dodir.

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.

OPTIMIZIRANJE FUNKCIJA I ESTETIKE
kod cementiranja ljuskica
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. 6. PANAVIA™ Veneer LC Paste immediately after seating. 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. 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.

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.

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.

Često postavljena pitanja
Q
Što je PANAVIA™ Veneer LC?
A
PANAVIA™ Veneer LC je svjetlosno stvrdnjavajući sustav adhezivnog cementa na bazi smole. Njegovi sastojci su PANAVIA™ Veneer LC Paste (svjetlosno stvrdnjavajuća cementna pasta), CLEARFIL™ CERAMIC PRIMER PLUS (silanski, cirkonijev i metalni premaz), K-ETCHANT Syringe (fosforna kiselina) i PANAVIA™ V5 Try-in Paste. Za tretiranje zuba može se odabrati CLEARFIL™ Universal Bond Quick ili PANAVIA™ V5 Tooth Primer.
Q
Koje su indikacije?
A
Cementiranje keramičkih i kompozitnih inleja, onleja i laminatnih ljuskica debljine manje od 2 mm od sljedećih materijala: keramika na bazi silicija (npr. konvencionalni porculan, litij disilikat), hibridna keramika, kompozitna smola i KATANA™ Zirconia STML/UTML/YML (debljine manje od 1,2 mm).
Q
Kako mogu obraditi protetsku restauraciju?
A
Slijedite upute za upotrebu restaurativnog materijala. U nedostatku posebnih uputa, preporučujemo sljedeće postupke i primjenu isporučenog premaza CLEARFIL™ CERAMIC PRIMER PLUS: ako je prianjajuća površina keramika na bazi silicija (npr. konvencionalni porculan, litij disilikat), hibridna keramika ili kompozitna smola: Ovisno o vrsti restauracije, može se koristiti jetkanje fluorovodičnom kiselinom ili obrada zračnom abrazijom:
Jetkanje kiselinom (npr. konvencionalni porculan, litijev disilikat):
Provedite jetkanje prianjajuće površine otopinom fluorovodične kiseline prema uputama za upotrebu otopine. Isperite prianjajuću površinu vodom i osušite.
Tretman zračnim pjeskarenjem (npr. kompozitna smola):
Ohrapavite prianjajuću površinu pjeskarenjem prahom aluminijevog oksida (30-50 μm) pri tlaku zraka od 0,1-0,2 MPa (1-2 kgf/cm2, 15-29 psi, 1-2 bar). Tlak zraka i veličina čestica praha trebaju odgovarati materijalu i/ili obliku protetske restauracije i potreban je oprez da se spriječi odlamanje komadića. Čistite protetsku restauraciju u ultrazvučnom čistaču 2 minute ili sredstvom za čišćenje KATANA™ Cleaner trljajući 10 sekundi i potom ispiranjem vodom.
Q
Može li se CLEARFIL™ Universal Bond Quick koristiti za površinsku obradu restauracija s veneer-ima?
A
Iako je to tehnički moguće, preporučujemo korištenje premaza CLEARFIL™ CERAMIC PRIMER PLUS za postizanje optimalne učinkovitosti na staklokeramici.
Q
Postoje li dodatni koraci, ako isprobam restauraciju nakon što je jetkana kiselinom ili nakon abrazije zrakom?
A
Da, to bi kontaminiralo restauraciju i, prema tome, smanjilo čvrstoću veze. Kako biste uklonili kontaminaciju, 10 sekundi trljajte sredstvom KATANA™ Cleaner, a zatim ispirite vodom sve dok boja ne nestane pa osušite restauracije ili nanesite štrcaljku K-ETCHANT Syringe (fosforna kiselina) 5 sekundi u slučaju restauracija koje nisu od cirkonija.
Q
Kako mogu obraditi pripremljeni zub?
A
Postoje 2 načina obrade pripremljenog zuba: temeljnim premazom PANAVIA™ V5 Tooth Primerom ili vezivom CLEARFIL™ Universal Bond Quick.
a) PANAVIA™ V5 Tooth Primer: Jetkajte caklinu štrcaljkom K-ETCHANT (fosforna kiselina) 10 sekundi, isperite i osušite. Četkicom za nanošenje nanesite Tooth Primer na cijeli pripremljeni zub i ostavite da djeluje 20 sekundi. Temeljito osušite cijelu prianjajuću površinu blagim mlazom zraka bez primjese ulja sušeći sve dok sva voda ne ispari s temeljnog premaza.
b) CLEARFIL™ Universal Bond Quick: Selektivno jetkajte caklinu štrcaljkom K-ETCHANT (fosforna kiselina) 10 sekundi, isperite i osušite. Četkicom za nanošenje i uz utrljavanje nanesite BOND na cjelokupnu pripremu. Nije potrebno čekati. Osušite u dovoljnoj mjeri cjelokupnu stijenku kaviteta primjenjujući blagi mlaz zraka najmanje 5 sekundi dok BOND ne bude nepomičan.
Kod cementiranja laminatnih ljuskica nema potrebe za svjetlosnim stvrdnjavanjem BOND-a prije namještanja ljuskica. Stvrdnjavanje je potrebno nakon postavljanja laminatnih ljuskica pomoću cementa PANAVIA™ Veneer LC. Kod cementiranja inleja ili onleja potrebno je svjetlosno stvrdnuti BOND prije namještanja restauracije. Potvrdite vrijeme stvrdnjavanja prema uputama za upotrebu.
Q
Koje su razlike u korištenju premaza PANAVIA™ V5 Tooth Primer ili adheziva CLEARFIL™ Universal Bond Quick prilikom obrade pripremljenog zuba?
A
Što se tiče čvrstoće veze, oba proizvoda su slična i daju izvrsne rezultate. Unatoč tome, PANAVIA™ V5 Tooth Primer pruža mehanizam „stvrdnjavanja na dodir” kojim se spojna površina brtvi prije završnog stvrdnjavanja svjetlom. Dodatno, dok je vrijeme nanošenja za CLEARFIL™ Universal Bond Quick kraće (bez vremena čekanja u odnosu na 20 s), PANAVIA™ V5 Tooth Primer omogućuje dulje vrijeme rada pod ambijentalnim svjetlom (200 sekundi u odnosu na 160 sekundi za BOND).
Q
Koje prednosti ima PANAVIA™ Veneer LC u odnosu na konkurentske proizvode?
A
PANAVIA™ Veneer LC pruža idealnu konzistenciju paste, koja nije previsoka ili preniska kao kod nekoliko konkurentskih proizvoda. To će olakšati nanošenje paste na restauraciju i omogućiti lagano postavljanje takve restauracije. Mala debljina filma i dugo vrijeme rada također su prednosti u odnosu na konkurentske proizvode. Osim toga, u slučaju korištenja s temeljnim premazom PANAVIA™ V5 Tooth Primer, mehanizam "„stvrdnjavanja na dodir” omogućit će brtvljenje spojne površine.
Q
Kako ukloniti višak cementa?
A
Može se koristiti jedna od sljedeće dvije tehnike:
Tehnika kratkog stvrdnjavanja i čišćenja: Svjetlom stvrdnite sav suvišni cement na nekoliko mjesta u trajanju od po 1 sekunde na udaljenosti od 10-15 mm. Držite protetsku restauraciju na mjestu, stomatološkim instrumentom uklonite suvišni cement stvrdnut svjetlom u kratkom vremenu.
Tehnika mokrog čišćenja: Sav višak cementa koji je ostao na rubovima može se ukloniti malom četkicom, spužvastim tamponom, zubnim koncem ili dentalnim strugačem.
Bez obzira na korištenu tehniku, završno stvrdnjavanje bit će potrebno kao sljedeći korak. Radi toga slijedite upute za upotrebu.
Q
Trebaju li rubovi biti prekriveni zaštitnim gelom tijekom završnog stvrdnjavanja?
A
Korištenje zaštitnog gela, kao što je PANAVIA™ F 2.0 OXYGUARD II, korisno je za sprječavanje stvaranja sloja inhibiranog kisikom što pomaže u stvaranju glatkih rubova.
Q
Koliko je nijansi paste PANAVIA™ Veneer LC dostupno?
A
Dostupne su 4 nijanse paste PANAVIA™ Veneer LC: Clear, Universal (A2); White i Brown (A4). Svaka nijansa ima odgovarajuću probnu pastu na bazi glicerina, topljivu u vodi.
Q
Kako se koristi PANAVIA™ V5 Try-In Paste?
A
Nijanse probne paste PANAVIA™ V5 Try-In Paste odgovaraju nijansama za PANAVIA Veneer LC (stvrdnutog svjetlom) i omogućuju simulaciju konačnog izgleda restauracije. PANAVIA™ V5 Try-In Paste ne može se (svjetlosno) stvrdnuti, a može se lako ukloniti vodom.
Q
Da li je PANAVIA™ Veneer LC postojane boje?
A
Da, boja paste PANAVIA™ Veneer LC je postojana.
Q
Što čini boju paste PANAVIA™ Veneer LC postojanom?
A
Budući da se pasta PANAVIA™ Veneer LC svjetlosno stvrdnjava, nije uključen redoks sustav stvrdnjavanja baziran na agensu za smanjenje amina čime se izbjegava neželjena diskoloracija tijekom vremena.
Q
Kolika je količina punila i veličina čestica?
A
Ukupna količina anorganskih punila je približno 66 mas%, 47 vol%. Veličina čestica anorganskih punila je u rasponu od 0,05 μm do 8 μm.
Q
Koji je glavni oblik punila paste PANAVIA™ Veneer LC?
A
Pasta PANAVIA™ Veneer LC sadrži sferični silicij i nano klaster punila. Ovo daje pastu koja nije tekuća, ima izvrsna svojstva pri rukovanju i otporna je na spuštanje.
Q
Kolika je debljina filma PANAVIA™ Veneer LC?
A
Debljina filma paste PANAVIA™ Veneer LC iznosi približno 8 μm.
Q
Može li se PANAVIA™ Veneer LC koristiti za cementiranje cirkonskih ljuskica i inleja/onleja?
A
Ne bi trebalo primjenjivati cirkonij, jer možda neće biti dovoljno translucentan. Međutim, cirkonij naših proizvoda visoke translucencije (KATANA™ Zirconia STML/UTML, KATANA™ Zirconia Block STML) može se primijeniti u debljini manjoj od 1,2 mm.
Q
Kakva je čvrstoća vezivanja PANAVIA™ Veneer LC?
A
PANAVIA™ Veneer LC ima izvrsnu čvrstoću vezivanja na nekoliko podloga (npr. caklinu, dentin, litijev disilikat, KATANA™ Zirconia, keramiku na bazi feldsapata) na sličnoj razini kao hvaljeni PANAVIA™ V5.
Q
Koliko se obrada može zacementirati jednom štrcaljkom?
A
Otprilike 20-30 zuba za laminatnu ljuskicu.
Q
Koriste li se za CLEARFIL MAJESTY™ ES Flow i PANAVIA™ Veneer LC isti nastavci za nanošenje?
A
Ne, nastavci za pastu PANAVIA™ Veneer LC posebno su dizajnirani za jednostavno istiskivanje i primjenu i njihova širina iznosi 16 (1,65 mm u promjeru) po tome se razlikuju od onih za CLEARFIL MAJESTY™ ES Flow.
Q
Kako trebam čuvati PANAVIA™ Veneer LC?
A
Proizvod treba čuvati u hladnjaku. Sve komponente pohranjene u hladnjaku moraju se ostaviti na sobnoj temperaturi 15 minuta prije upotrebe kako bi se postigla normalna svojstva viskoznosti i stvrdnjavanja.
Q
Koliki je rok trajanja komponenti PANAVIA™ Veneer LC?
A
Rok trajanja komponenti PANAVIA™ Veneer LC je 36 mjeseci od datuma proizvodnje uz čuvanje na hladnom mjestu.
