EENVOUDIG, VOORSPELBAAR EN HERHAALBAAR

Interview met Dr. Michał Jaczewski

 

Kan je de techniek kort beschrijven?

 

De Flowable Injection Technique biedt een eenvoudige, voorspelbare en reproduceerbare manier om restauraties uit te voeren met vloeibaar composiet. Het is gebaseerd op een wax-up, waarvan een siliconenindex wordt geproduceerd. Deze index dient vervolgens als mal voor het injecteren van de vloeibare composiet. Hierna wordt door de transparante siliconenmal, het composiet met licht uitgehard. Het belangrijkste voordeel is dat deze techniek werkt zonder, of in sommige gevallen met zeer minimale, weefselopoffering. Het is een populaire techniek voor zowel beginnende als ervaren tandartsen. Met behulp van een composiet met een uitgebalanceerde dekking, gebruikt in een dikte van ca. 0,3 mm en een speciaal polijstprotocol, creëer je een uitstekende morfologie en bereik je prachtige optische resultaten.

 

Wanneer ben je begonnen met het gebruik van de Flowable Injection Technique en wat zijn de belangrijkste indicaties?

 

Ik begon de techniek in 2018 te gebruiken. Oorspronkelijk was die ontwikkeld voor anterieure restauraties, maar tegenwoordig is hij ook succesvol toe te passen in het posterieure gebied. Ik vind het voornamelijk handig wanneer de vorm van meerdere tanden moet worden gecorrigeerd om de glimlach van een patiënt te verbeteren, ongeacht jong of oud. Dit is vaak het geval na een orthodontische behandeling. Na de regulering restaureer je op eenvoudige wijze en creëer je de perfecte vorm en esthetiek met behulp van deze niet-invasieve methode. Ik gebruik de Flowable Injection Technique ook voor een smile-make-over, om slijtage defecten te herstellen en de occlusiehoogte aan te passen in het geval van een volledige reconstructie. In het laatste geval is de restauratie mogelijk tijdelijk en wordt gebruikt voor een “proefrit” op middellange tot lange termijn. Maar ook vaak als definitieve restauratie.

 

Hoe begin je met de Flowable Injection Technique?

 

De belangrijkste fase die het succes van deze techniek sterk beinvloedt is de planningsfase. Die bestaat uit het maken van het behandelplan waaronder het vervaardigen van afdrukken, een wax-up en een mock-up, evenals de productie van de siliconenindex. Je kunt uiteraard op de traditionele manier werken met een siliconenafdruk en conventionele wax-up, maar het gebruik van digitale technieken verbetert de workflow aanzienlijk. Ik begin meestal met foto- en videodocumentatie en een digitale impressie. Registratie van de centrale relatie en occlusie zijn ook nodig. Vervolgens wordt een virtuele wax-up gemaakt met behulp van Digital Smile Design software (DSD). Bij deze stap is het belangrijk om rekening te houden met de gezichtskenmerken van de patiënt, bijvoorbeeld via het face-flow-concept. Gebaseerd op het resulterende ontwerp presenteer je een virtueel behandelresultaat en bespreek je deze met de patiënt. Eenmaal goedgekeurd wordt het model via de wax-up in verschillende versies vervaardigd: een volledige fuctionele wax-up en een alternerend, zogenaamd “interlip model”. Deze modellen gebruik je om de siliconen indexen te (laten) vervaardigen.

Siliconenindex geproduceerd op de alternerende (interlip) wax-up

 

Wanneer maak je meer dan één siliconenindex, en waarom?

 

Het is vooral nuttig om te werken met zowel de volledige als de alternerende siliconenindex wanneer alle tanden in de bovenkaak worden gerestaureerd. Met de alternerende index verkrijg je extra stabiliteit en leg je, vooral ten aanzien van de beoogde occlusale hoogte, de basis voor een trefzeker resultaat. In de onderkaak is het werken met de index en composiet lastiger vanwege de aanwezigheid van speeksel en beweeglijk zacht weefsel. Ik raad altijd aan om daar het werkgebied te verdelen in drie secties - één anterieure en twee posterieure - en die apart te bewerken.

 

Hoe bereid je de elementen voor en injecteer je het vloeibare composiet?

 

In de meeste gevallen is het enige wat je moet doen, het opruwen van het glazuuroppervlak voor de hechtingsprocedure. Ik zandstraal meestal met aluminiumoxide (50 μm op lage druk). Vervolgens ets ik het glazuur met fosforzuur en breng een universele bonding aan. De siliconenindex is voorzien van een injectieopening ter plaatse van de incisale rand. Hierin wordt gemakkelijk de naaldpunt van de vloeibarecomposietspuit naar binnen gebracht. Het is raadzaam om posterieur een harder materiaal voor de index te gebruiken en ter hoogte van de knobbels twee afzonderlijke gaten te maken voor elk element – één voor de injectie en één voor de ‘ontluchting’. Bij gebruik van een harde index is een diamantboor nodig om de gaatjes mee te maken. Ik plaats de index, injecteer de vloeibaar composiet van onderaf, hard het materiaal kort uit en verwijder de index. De finale polymerisatie voer ik uit na het verwijderen van de index onder een laagje glycerinegel. Zodra de overmaat aan composiet is verwijderd en het proximale deel van de restauratie geperfectioneerd is, wordt de procedure bij de andere elementen herhaald waarna de restauraties gepolijst worden.

 

Heb je favoriete producten voor de techniek?

 

Voor de siliconenindex gebruik ik Exaclear (GC), omdat dit de meest transparante silicone is die op de markt verkrijgbaar is. Maar er zijn meer fabrikanten die doorzichtig materiaal van goede kwaliteit leveren die uitstekend geschikt zijn voor het beoogde doel. Mijn favoriete composiet voor de Flowable Injection Technique is  CLEARFIL MAJESTY™ ES Flow  Low (Kuraray Noritake Dental Inc.). In mijn praktijk en tijdens mijn cursussen heb ik de kans om veel verschillende producten te testen. In deze context ontdekte ik dat het materiaal van Kuraray Noritake Dental een aantal voordelen biedt boven andere fabrikaten. Het is een modern nanocomposiet met een breed scala aan indicaties en een groot kleuraanbod. Met zijn drie vloeibaarheden biedt het flexibiliteit en is het in te zetten tijdens veel verschillende klinische situaties. Ik begon het vijf jaar geleden te gebruiken voor de Flowable Injection Technique. De variant met de middelste viscositeit (Low) is mijn eerste keuze, omdat deze de meest universele is, geschikt voor zowel anterieur als posterieur. De meest doorslaggevende voordelen die van invloed waren op mijn beslissing zijn de natuurlijke esthetiek en superieure polijstbaarheid. Je bereikt een spectaculair effect zonder extreme vaardigheden aan te moeten leren. Mijn voorkeursbonding is CLEARFIL™ Universal Bond Quick, dit onder andere om mijn workflow nog eenvoudiger, sneller en voorspelbaarder te maken. Voor het polijsten heb ik mijn eigen protocol ontwikkeld.

 

Hoe werk je restauraties af en polijst je ze?

Ik begin in het proximale gebied met polijststrips en soms een proximale zaag. Voor vormaanpassingen gebruik ik drieverschillende diamant- en hardmetalen boren die hun waarde hebben bewezen. Vervolgens ga ik over tot fijn of extrafijn afwerken met schuurschijfjes en hierna polijst ik met de flexibele polijstrubbers, TWIST DIA™(Kuraray Noritake Dental), die al een mooi, natuurlijk, glanzend oppervlak creëren. Hierna gebruik ik een wielvormige borstel van geitenhaar met diamantpolijstpasta en ten slotte een katoenen borstel met een aluminiumoxide-polijstpasta. Op deze manier creëer je een prachtige natuurlijke hoogglans.

Wat zijn de grootste voordelen van de Flowable Injection Technique?

 

Voor patiënten en tandartsen zijn de grootste voordelen besparing in tijd en geld. Veel patiënten zijn heel blij met dit kwalitatief hoogwaardig alternatief voor keramische veneers. De procedure vereist geen voorbereiding. Indien gewenst zijn aanpassingen in vorm en kleur eenvoudig te realiseren. Het is een behandelingsoptie met slechts een beperkt risico. Als tandarts kan je vaak al beginnen met het behandelen van patiënten na het volgen van één goede cursus. Wetende dat oefening leidt naar perfectie, zijn de eerste resultaten toch vaak al behoorlijk indrukwekkend, zodat er geen sprake is van enorm investeringen voor beginners – noch in tijd, noch in nieuwe materialen. Natuurlijk kun je veel tijd investeren in de afwerkings- en polijstprocedure, maar ik weet zeker dat u de juiste balans tussen inspanning en resultaat zult vinden.

Heb je een aanbeveling hoe de techniek te gebruiken?

 

Allereerst wil ik iedereen aanmoedigen om de comfortzone te verlaten, probeer regelmatig iets nieuws. Voor mij is het werken met de Flowable Injection Technique echt een gamechanger gebleken en ik zou nooit meer zonder willen. Voordat je de techniek toepast in de praktijk, adviseer ik zeker een cursus te volgen die je alles leert. In ieder geval de theoretische kennis die nodig is voor een succesvolle eerste behandeling en misschien zelfs een praktische workshop. Ik bied beide soorten regelmatig aan met mijn lezingen en hands-on cursussen.

Flowable Injection Technique: how to polish composite restorations?

By Dr. Michał Jaczewski

 

The durability of a composite restoration depends on many factors. Some are outside the practitioner's sphere of influence and are strongly patient-related. For example toothbrush and toothpaste type, brushing technique, diet, stimulants and hygiene habits all have an impact on the restoration. Following the best finishing and polishing protocol, however, is fully up to the dentist.

 

Correct polishing aims to remove the oxygen inhibition layer and produce a smooth restoration surface. A properly polished restoration will not absorb staining agents from food, drink or stimulants that lead to discoloration of the composite, ensuring a long-lasting aesthetic result of the restoration.

 

Polishing the composite is a process to which special attention should be paid. It consists of several steps and principles:

 

  • The use of finishing discs allows for a smooth restoration surface , excess composite to be removed and the final shape to be given to the restoration. It is important to remember to work on a moistened surface with a maximum speed of 5,000-10,000 rpm on a 1:1 dental handpiece.

 

  • Polishing rubbers, there are many types and shapes on the market. One of the most universal designed specifically for composite is TWIST™ DIA for Composite. This is a set consisting of two rubbers with different levels of abrasion. The first (dark blue) is used for preliminary rough polishing, the second (light-blue) for final gloss and smoothness. It should be remembered that working with these tools should be carried out on a dry surface without water cooling. Dry working carries the risk of irritating the dental pulp, so the working speed should be limited to between 5000 and 10000 rpm and excessive pressure must be avoided.

 

  • The next step is to use a diamond polishing paste with a gradient of 1 to 5 microns. The use of a polishing goat wheel brush is recommended to use with this paste. The type of brush is not important, however, don’t use rigid bristles that could scratch the composite. Using the polishing brush and polishing paste make it possible to reach places which are difficult to access, such as the cervical area and proximal surfaces. In addition to this step, a celluloid diamond containing abrasive strip is used to polish the proximal surfaces more precisely. In order not to alter the contact points, low abrasive (Super Fine) strips should be used.

 

 

  • A further step to increase the gloss of the restoration and to protect it against discoloration is an aluminum oxide paste with a cotton polishing brush. The use of such paste, originally dedicated to ceramics, results in an exceptionally smooth surface and a high gloss of the restoration surface. This step is carried out in a dry environment at a maximum speed of 5,000-10,000 rpm.

 

In all techniques, thus also the Flowable Injection Technique, the level of polishing influences the durability and the optical and aesthetic properties of the restoration. This key step in tooth restoration should therefore devoted sufficient time. Composites are characterized by different compositions and amounts of fillers which not only influence their properties, but also the ease with which they can be polished. In some cases, the procedure has to be repeated several times to achieve a "mirror effect". CLEARFIL MAJESTY™ ES Flow is a composite which is very easy to polish to a high shine level, despite its high filler content. Specially adapted rubbers, brushers and pastes enable easy creation of a smooth surface thereby contributing to a lasting result.

Universal adhesive for durable bond with quick and simple procedure

AWARD WINNING PRODUCT

CLEARFIL™ Universal Bond Quick has again been named a 2024 Preferred Product in the bonding agent category by DENTAL ADVISOR, which also recognized this universal bonding agent as an Editor’s Choice bonding agent. DENTAL ADVISOR’S roster of award-winning dental materials and equipment found by its evaluators to deliver the best practice-based performance was announced in its JAN/FEB 2024 issue.

 

ABOUT THE PRODUCT

CLEARFIL™ Universal Bond Quick is a single-bottle, fluoride-releasing universal adhesive suitable for all direct and indirect restorations using a quick and simple technique. The material utilizes Rapid Bond Technology, merger of MDP monomer with new hydrophilic amide monomers, which creates a strong chemical bond to hydroxyapatite. Thanks to the amide monomer, which is highly hydrophilic, the adhesive quickly penetrates dental tissue to create a fast chemical bond to dentin and enamel, eliminating the need for prolonged scrubbing application of the adhesive into the dentin and long waiting times. After curing, the innovative amide monomer forms a moisture-resistant cross-linked polymer network.

 

APPLY AND PROCEED

Despite its ease of use and reduced application and wait times, there is no tradeoff in terms of bond strength: CLEARFIL™ Universal Bond Quick delivers a bond that is moisture-resistant, stable, and durable.

 

 

VERSATILITY OF APPLICATION

This fast and versatile agent bonds directly to dentin, enamel, metals, zirconia and lithium disilicate restorative materials, and is appropriate for bonding direct and indirect restorations; it can also be used for total-etch, selective-etch, or self-etch methods.

 

 

CLEARFIL™ Universal Bond Quick is also an excellent choice when doing post cementation and core build-up procedures with CLEARFIL™ DC CORE PLUS . It can be used for treatment of the post surface, be it fiber or metal, but also for the tooth surface preparation before cementing with PANAVIA™ SA Cement Universal, for example. Universal excellence at its best!

 

REMARKS FROM EVALUATORS

practitioners evaluating the CLEARFIL™ Universal Bond Quick commented on its ease in dispensing and placement, viscosity, suitability for all bonding procedures, and convenience. Among their remarks were: "Quick application and cure time is ideal for situations where isolation is difficult, especially in a high moisture area.", "Loved that it is compatible with dual/self-cured resins and that it can be used in self-cure mode with CLEARFIL™ DC Activator”. and “It is compatible with virtually any bonding procedure."

Selective Adhesive Luting: A Novel Technique

Selective Adhesive Luting (SAL) is a hybrid technique for universal resin cements. It entails the application of a universal adhesive system only on easily accessible abutment surfaces, enabling simultaneous adhesive and self-adhesive luting in different portions of the abutment. A description of this novel technique and scientific evidence for the achieved effects is provided in this article authored by Prof. Breschi and colleagues from the University of Bologna. Its title:“Selective adhesive luting: A novel technique for improving adhesion achieved by universal resin cements”.

 

A VERSATILE RESIN CEMENT

PANAVIA™ SA Cement Universal is a universal resin cement that may be applied in the self-adhesive mode – without any additional components – in many clinical situations. It even offers great bonding performance to lithium disilicate without the need for a separate bottle of silane. In-vitro studies have shown that the resin cement is moisture tolerant and versatile, establishing a strong and durable bond to virtually all kinds of restorative materials as well as to enamel and dentin.

 

ENHANCING THE BONDING PERFORMANCE

On the side of the tooth, however, the best possible bonding performance is obtained by applying CLEARFIL™ Universal Bond Quick as a separate tooth primer. Hence, you may want to settle for this two-component adhesive luting technique in particularly challenging situations. It is still less complex than traditional adhesive luting and produces excellent outcomes.

 

MOISTURE SENSITIVITY AND WORKING FIELD CONSIDERATIONS

To function properly, however, universal adhesives need a completely dry working field, while self-adhesive resin cements are less sensitive to moisture. Thus, you might wonder which technique is best suited if you need the strongest possible chemical bond to enamel and dentin, but proper isolation with rubber dam is challenging or impossible – for example, because the abutment is short or the preparation margin is in a subgingival position. The solution in this case is termed Selective Adhesive Luting.

 

Selective application of a universal adhesive to those areas of etched enamel that are not at risk of being contaminated by moisture.

 

Flowable Injection Technique. What to do to avoid air bubbles in composite restorations?

Article by Dr. Michał Jaczewski

 

COMPOSITE RESTORATIONS IN DENTISTRY

Composite restoration is the most common procedure performed by the dentist. There are many restorative techniques and a variety of restorative materials used in dentistry. Regardless of the type of material, the method of restoration and where it is applied, common issue is air bubbles in or at the surface of the composite layers. The composite restoration should be homogeneous to ensure the tightness of the filling and its durability. Repairing bubble defects is tedious and sometimes requires the replacement of the filling or part of it. Depending on the type of composite (flowable or paste composite) and/or the placement technique, the amount of defects may vary, but there are several causing factors.

 

MATERIAL CHOICE

In the Flowable Injection Technique, we use flowable composites, which obviously flow easily but are also sensitive to incorrect application. The first cause of forming air bubbles is the homogeneity of the material itself. Bubbles can be incorporated in the syringe at the manufacturing stage or during use. By using premium products, we can be sure that the highest quality material is supplied, and that the structure and design of the syringe allows for proper operation to reduce the formation of air bubbles within the material.

 

 

IMPORTANCE OF SYRINGE DESIGN 

CLEARFIL MAJESTY™ ES Flow composite is designed to prevent the formation of air bubbles during dispensing. The special design of the syringe and plunger limit the possibility of dripping as well as backflow of the material during or after dispensing.

 

 

A unique safety feature inside the syringe is the special O-ring construction which prevents the material from flowing after pressure is released and at the same takes care for minimal retraction but avoiding the plunger from retracting too much.

 

 

RETRACTION OF PLUNGER

Another cause of air bubble formation is the incorporation of air into the syringe by deliberate retraction of the plunger. If the practitioner or ancillary staff have a habit of retracting the plunger after administering the composite, they may cause air to enter the syringe. During a following use the air will more than likely show up in the restoration as an air void.

 

IMPORTANCE OF PRESSURE ON THE INDEX

In the Flowable Injection Technique, we use a silicone index in which we apply the material to build up the tooth. The index should fit tightly to the tooth and should not move or being moved during injection. If it does air bubbles may show up. Pressing and then releasing the index will cause a suctioning effect and pull the composite away from the tooth as well as from the index. To avoid defects, constant pressure on the index should be maintained from the moment the material is injected until polymerisation.

 

 

 

Various modifications of the silicone index can be used to limit its mobility and reduce the risk of uncontrolled pressure on the tooth. Such an example is the index made on the interlip ("one yes one no") model, which provides a very high degree of stability as well as working safety.

 

 

WIDTH OF THE INJECTION HOLE

Another cause for getting air in the restoration is the width of the injection hole. If the hole is too tight, the index can be moved by the application tip during insertion or application. To avoid this problem, the hole could be widened to allow free insertion as well as manipulation of the tip during injection. A wider opening also allows any air to escape during dispensing. Most important , however, is to apply the material at continuous pressure and avoiding pulling out and reinserting the tip into the index. This may result in a non-uniform composite layer.

Versatile flowable composite for everyday dental challenges

AWARD WINNING PRODUCT

For the 9th year in a row, CLEARFIL MAJESTY™ ES Flow (Low) has been named a Top Product by Dental Advisor, which announced in its JAN/FEB 2024 issue its choices for dental materials and equipment found to deliver the best practice-based performance based on the publication’s annual review of such products.

 

ABOUT THE PRODUCT

CLEARFIL MAJESTY™ ES Flow, which is available in three different levels of flowability, was the Top Product honoree in the Direct Restorative Category and was also given Editor’s Choice award for its medium viscosity version - Low.

 

Rather than limit practitioners to a single viscosity that might not be ideal for all flowable composite indications, CLEARFIL MAJESTY™ ES Flow comes in one version firm enough to stay in place when applied, another malleable enough to fashion a specific shape, and a third runny enough to flow into every corner or undercut. The practitioner would thus be able to select the best version for the job at hand—choosing the high flowability variant for cavity linings and as a resin coat in immediate dentin sealing (IDS) procedures, but instead, the super low flowability option for direct veneer procedures and for the build-up of cusps, etc.

Beyond its handling advantages, this universal flowable composite, which incorporates Kuraray Noritake Dental Inc.’s Light Diffusion Technology, is highly esthetic, with optical properties that enable the practitioner to fashion lifelike restorations that integrate seamlessly with the surrounding tooth structure.

 

EVALUATION

The flowable composite tested by the 29 DENTAL ADVISOR consultants in 909 uses in their dental practices was the medium flowability variant CLEARFIL MAJESTY™ ES Flow (Low). Their evaluations focused on properties including placement/handling, esthetics, viscosity, and polishability, and they rated all these key features to be “excellent”. This led to a recommendation rate of 100% and a 98% overall clinical rating.

 

REMARKS FROM EVALUATORS

Among their comments were: “The material blended so well with the tooth structure that you had to really look to find the interface.”. “Readily apparent on radiographs.” and “One of the best flowable composites I have used.”.

How to polish a composite restoration in posterior area?

By Dr. Aleksandra Łyżwińska, Warsaw, Poland.

 

Every dentist aims to polish to a high gloss without damaging the freshly modeled occlusal surface. Firstly, use high-quality polishing rubbers. The plural form is not accidental (Fig. 1). In my opinion, a single rubber systems are not capable of achieving an impeccable gloss in a safe manner. Be patient and gentle. Polishing requires time and a delicate touch.

 

Fig. 1.

 

Immediately after polymerization the composite is covered with an oxygen inhibition layer (Fig. 2). It is imperative to remove it by a brush and any polishing paste or a prophylactic sandblaster. The next step is to remove excess composite using abrasive discs, burs and firm polishing rubber points.

 

Fig. 2.

 

During polishing without water cooling, the rubber leaves crumbling on the composite surface (Fig. 3). These fragments can be spread across the restoration surface using a fine nylon brush. This allows for the polishing of each fissure and pit (Fig. 4).

 

Fig. 3.

 

Fig. 4.

 

The key to long lasting shine is polishing with gradation. Time to change a rubber point to the dark blue TWIST DIA for Composite rubber, which is more abrasive than light blue one (Fig. 5). Remember to apply gentle pressure and maintain a maximum speed of 8000 revolutions per minute. This way, you will achieve fine particles without the risk of overheating the pulp. The particles were once again spread over the entire surface. The thinner the bristle, the better the polishing effect in the grooves (Fig. 6).

 

Fig. 5.

 

Fig. 6.

 

Third round: use the light blue TWIST DIA for Composite rubber for a mirror-like gloss (Fig. 7). A beautiful gloss emerges beneath the particles. An alternative to thin nylon brushes is brushes made from natural goat hair (Fig. 8).

 

Fig. 7.

 

Fig. 8.

 

Polishing is not only a matter of aesthetics but, above all, function. The adherence of bacterial biofilm to a polished composite is significantly lower than to a rough surface (Fig. 9). My recipe for achieving a mirror-like gloss polish: high-quality diamond rubber points with gradation, used with sensitivity over an extended period (Fig. 10).
