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.

Innovativ teknologi bag PANAVIA Veneer LC

I dette Highlights kommer vi ind på de teknologier og de mange fordele ved den nye PANAVIA Veneer LC

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

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.

INNOVATIV HÆRDNINGSTEKNOLOGI
PANAVIA™ Veneer LC er en lyspolymeriserende cement, der kombinerer flere teknologier for at give dig den højest mulige bindingsstyrke.

FORSEGLING AF ADHÆSIONSFLADEN
Modificeret kontakthærdningsteknologi bruges til at opnå en længere arbejdstid, samtidig med at den høje bindingsstyrke, som PANAVIA™ er kendt for, bevares. PANAVIA™ Veneer LC kombineret med PANAVIA™ V5 Tooth Primer tilfører et vigtigt kemisk element til en lyspolymeriserende cement.

PANAVIA™ V5 Tooth Primer som er en selvætsende primer til tandstruktur (dentin og emalje), forsegler tandoverfladen sikkert, så snart PANAVIA™ Veneer LC kommer i kontakt med den. Denne ”milde” kontakthærdning initierer kun polymeriseringen ved adhæsionsfladen og skaber en øjeblikkelig stærk binding til emalje og dentin, men påvirker ikke cementens afbinding og dermed heller ikke arbejdstiden.

ARBEJDSTID
Under cementeringsprocedurer påvirker flere eksterne faktorer din arbejdstid. Teknologien bag PANAVIA™ Veneer LC tager højde for disse
faktorer. Kontakthærdningsteknologien giver mulighed for øjeblikkelig forsegling af adhæsionsfladen. Grundlaget for høje bindingsstyrker.
Lyspolymeriseringsteknologien giver dig en arbejdstid på 200 sekunder under omgivende lys*, før PANAVIA™ Veneer LC begynder at miste sin
ideelle formbarhed. I løbet af disse 200 sekunder kan du nemt placere og positionere op til flere facader. Den endelige polymerisering finder
sted under belysningen med hærdelampen og gør at cementen hærder fuldstændigt.
*Omgivende lys; ca. 8.000 lux

NYE FYLDSTOFFER
PANAVIA™ Veneer LC’s fremragende håndtering forbedres yderligere af de nyudviklede sfæriske silikafillere (fillerindhold: 66 vægtprocent, 47 volumenprocent). Takket være cementens tiksotrope egenskaber kommer facaderne ikke til at glide eller løsne. PANAVIA™ Veneer LC giver en kontrolleret påføring, den bliver siddende, der hvor den påføres, men flyder godt under placering af facaden/facaderne. Takket være dens konsistens og lave filmtykkelse (≈ 8 μm) giver PANAVIA™ Veneer LC et tyndt, jævnt fordelt cementlag. Dette bidrager til nem placering uden forstyrrelser. Desuden gør anvendelsen af kun små, sfæriske fillere (partikelstørrelse; 0,05 μm - 8 μm) det muligt at opnå meget æstetiske og glatte kantområder og byder på forbedret polerbarhed og glansbestandighed.

SILIKAFILLERE
Nyligt udviklede sfæriske silikafillere i cementen sørger for, at den bliver siddende, hvor den påføres, men flyder godt under placering af facaden. Giver mulighed for nem placering, uden at facaden glider eller løsner. Ved applicering på facadens indre overflade klæber resincementen ikke til påføringsspidsen, en egenskab, der opnås ved tilsætning af sfæriske nanoklynge-fyldstoffer.

Disse nye fillertyper resulterer
i fremragende glatheds,
glansbevaring samt nem
håndtering.

VISKOSITET OG TIKSOTROPI
Viskositeten på en cement er vigtig og skal være tilstrækkelig lav for at forhindre protesen i at sprække under placeringen. Samtidig må
den ikke være så flydende, at den løber af under applicering og placering af restaureringen.
Da PANAVIA™ Veneer LC indeholder en optimeret fyldstof/resinblanding, kan dens viskositet ændres under tryk. Fænomenet kaldes
tiksotropi. Cementen bliver mere flydende under tryk under placeringen og positioneringen af facaden. Når trykket falder, øges
viskositeten igen. På grund af den tiksotrope egenskab ved PANAVIA™ Veneer LC, er cementen nem at dosere, og det kræver kun let
tryk at placere restaureringen, og det overskydende materiale er let at fjerne. Kort sagt: maksimal kontrol.

Materialer med samme viskositet har ikke nødvendigvis samme tiksotropi. Temperatur og tryk påvirker viskositeten. Graden og
hastigheden, hvormed et materiale vender tilbage til sin oprindelige viskositet, når trykket reduceres, afhænger af materialets tiksotropi.

LAMINATE VENEER RESTORATION
USING LITHIUM DISILICATE

WITH PANAVIA™ Veneer LC (Clear)
Case by Yohei Sato (DMD, PhD) and Keisuke Ihara (CDT)

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
prosthesis‘ IFU. After trial fitting, the intaglio surface of the
laminate veneer was cleaned with KATANA™ Cleaner.

Fig. 6 CLEARFIL™ CERAMIC PRIMER PLUS was applied and
dried to prime the restoration.

Fig. 7 The preparation was cleaned with KATANA™ Cleaner.
Applied and rubbed for more than 10 seconds. Then, it
was washed off sufficiently (until the cleaner color had
completely disappeared), and dried with compressed air.

Fig. 8 K-ETCHANT Syringe was applied and left for 10
seconds before water-rinsing and compressed air-drying.

Fig. 9 PANAVIA™ V5 Tooth Primer was applied and left for 20
seconds before mild compressed-air drying.

Fig. 10 PANAVIA™ Veneer LC Paste was applied to the
intaglio surface of the laminate veneer.

Fig. 11 The laminate veneer was seated and the fit
checked. Then, the excess cement was tack-cured (not
more than 1 second at each point) and removed. Finally,
the restoration was light-cured and finished.

FINAL SITUATION

USING KATANA™ Zirconia STML

WITH PANAVIA™ Veneer LC (Clear)
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.

Fig. 4 A layer of porcelain was applied to each KATANA™
Zirconia STML laminate veneer to complete the restorations.
The inner surface of each restoration was sandblasted, being
careful to prevent chipping.

Fig. 5 After trial fitting, bonding inhibiting substances as
blood and saliva were removed using KATANA™ Cleaner.

Fig. 6 CLEARFIL™ CERAMIC PRIMER PLUS was applied and
dried using compressed air.

Fig. 7 The surface of each tooth was cleaned and treated
with K-ETCHANT Syringe for 10 seconds before washing it
away with water and drying with compressed air.
