Clinical Cases Treatment of a carious lesion with a single posterior shade composite 1 de mar. de 2022 Case by Dr. Nicola Scotti When restoring posterior teeth with resin composite, functional aspects such as tight and anatomically correct proximal contacts and a naturally shaped occlusal surface that is wear-resistant and antagonist-friendly are even more important than a perfect optical integration. This is why every dental practitioner should avoid spending a lot of time on shade selection in these cases and focus on the factors that have an impact on the reliability and longevity of the restoration. Great support in accomplishing this task is offered by CLEARFIL MAJESTY™ ES-2 Universal, a resin composite with a single universal shade (U) for the posterior region that eliminates the need for shade taking and selection. At the same time, it offers good marginal adaptation, low shrinkage stress and high wear resistance needed for great long-term results. Fig. 1.

Treatment outcome immediately after rubber dam removal. The proximal contact is tight and the occlusal anatomy well-shaped for the patient’s individual masticatory dynamics. The margin of the restoration is virtually invisible, while the buccal cusp appears lighter due to dehydration of the natural tooth structure. FINAL SITUATION Fig. 8. Treatment outcome after two months. Conclusion The present case demonstrates that the selected composite is well-suited for simplified restoration procedures in the posterior region. The material handles well, offers the same mechanical properties as other materials from the CLEARFIL MAJESTY™ ES-2 series and blends in harmoniously with the surrounding structures without being too translucent. This way, it is possible to waive the shade-taking process without compromising the treatment outcome. The time saved in this context may be spent on functional aspects – or even on another patient.

Clinical Cases Simplified direct restoration procedure in the lower anterior region 1 de fev. de 2022 Case by Adham Elsayed If we ask dental patients what they expect from direct restorative treatments, they will most probably mention a quick procedure – as nobody wants to sit in a dental chair for a long time – and highly aesthetic outcomes. Reducing the treatment time is also something every dental practitioner should strive for, as their own time is the most precious asset they have. Fortunately, saving time becomes easy when appropriate high-quality materials and techniques are selected, as demonstrated using the following patient case. The patient presented with several small carious lesions in the lower anterior region. In order to save time without compromising the quality of the outcomes, it was decided to opt for a simultaneous direct treatment approach involving the use of a universal adhesive and a universal restorative with a streamlined shade offering. It consists of two shades for the anterior region, which are typically applied in a single-shade approach and have optimized optical properties that allow for a smooth optical integration. The images shown below speak for themselves… Fig. 1. Initial situation. Several caries lesions are detected on the lower anterior teeth. Fig. 2.

News Feature Invisible transition from tooth to composite 28 de out. de 2021 Article by Peter Schouten. We've seen them all: composite fillings that function present clinically, but are too ‘visible’ to be called aesthetic. The much-used term 'white filling' is probably quite appropriate here. In comparison to the tooth structure, these restorations are too opaque, or sometimes too transparent. How much better would it be if the composite helped to create a seamless transition between tooth structure and composite? The so-called 'blending'. But what enables this 'blending’ of composite and tooth structure to occur? The secret lies in utilizing the right mix of different filler particles and resins which give CLEARFIL MAJESTY™ ES-2 its light-diffusing properties. By varying the proportion of light-diffusing particles and the amount of pigment, it's possible to create composites with differing light-scattering properties and opacities. The most opaque variants contain more light-diffusing particles and more pigment. The more translucent ones contain obviously less. All CLEARFIL MAJESTY™ ES-2 variants have the same filler content. This is important, as it means that the mechanical properties of all the CLEARFIL MAJESTY™ ES-2 variants are the same. The more translucent variants contain more barium glass than the more opaque variants. A higher barium glass content can lead to a less workable composite. With CLEARFIL MAJESTY™ ES-2, this is not the case. Kuraray has mastered the silanization process to such an extent that all variants, whether translucent or opaque, have the same filler amount, without compromising on workability. Light diffusion test Light diffusion properties are easy to see if the thin composite slices are placed on a black and white paper background and then held a few millimeters above the paper. Composites with high diffusion properties make the black strip virtually invisible. They blend in more readily with their surroundings.
Clinical Cases Single-shade concept: an adequate option in direct posterior restorations 21 de out. de 2021 Case by Dr. Salvatore Scolavino After decades of developing and improving the matrix chemistry and filler technology contained in resinbased composites, the products available for direct restorative procedures finally seemed technically mature. What remained challenging, however, was the management of the extremely wide range of tooth shades and opacities available for each product: The dentin, body and enamel masses had to be selected and combined in the right way to obtain a perfect colour match and optical integration with the surrounding tooth structure. The difficulties associated with shade selection and calibration of layer thicknesses (particularly the top enamel layer) required to obtain the desired optical (desaturation) effects have now also finally been overcome. The reason is that further improvements of the composites’ optical properties, mainly achieved through a careful selection and combination of fillers, have enabled the production of materials with optimized light diffusion properties. These properties enable the restorations to blend in smoothly with the adjacent tooth structure, thus paving the way for a single-shade concept (SSC). This concept involves the use of a single mass of composite to restore the function and aesthetics compromised by the loss of dental structure. This translates into a significant saving of chair time and a high predictability of aesthetic outcome. A composite material supporting a single-shade technique needs to have medium opacity and a technology ensuring that the incoming light is absorbed, reflected and scattered in the right way to merge effortlessly with the surrounding natural dentition and create a biomimetic effect. The following clinical case reveals how the Light Diffusion Technology used in the CLEARFIL MAJESTY™ ES-2 Universal composite system (Kuraray Noritake Dental Inc.) leads to a highly predictable aesthetic integration obtained using the SSC. Case description The 30-year-old female patient presented for a check-up, during which it appeared that her composite restorations in the second quadrant (the maxillary left first and second molar) needed to be replaced due to marginal leakage (Fig. 1). Once the rubber dam was in place (Fig. 2), the existing composite restorations were removed using a round multi-blade bur, which allowing for a selective removal of composite and carious tissue. The extension of the cavity was performed with a truncated cone diamond bur (fine). Once the cavity preparation was completed (Fig. 3), the enamel and dentin surfaces were cleaned by sandblasting with aluminium oxide (50 μm). Selective etching of the enamel was performed with K-ETCHANT Syringe (Kuraray Noritake Dental; Fig. 4), followed by thorough rinsing and drying of the tooth (Fig. 5). For the adhesive procedure with CLEARFIL™ SE BOND 2 (Kuraray Noritake Dental), the primer was applied first (Fig. 6), rubbed into the tooth surface for 40 seconds and air-dried. The bond was subsequently applied in the same manner (Fig. 7). After several seconds of air flowing to create homogeneous surface the adhesive was light-cured for 40 seconds (Fig. 8). As the last phase of the adhesive procedure, a 1-mm-thick layer of flowable composite (CLEARFIL MAJESTY™ ES-Flow Super Low A3, Kuraray Noritake Dental) was applied to cover the adhesive on the dentin (Figs. 9 and 10).

In the modelling phase, the posterior shade U of the composite CLEARFIL MAJESTY™ ES-2 Universal was placed using the cusp-by-cusp technique (Figs. 11 and 12). In order to improve the optical integration of the restorations, some brown stain (CHROMA ZONE™ COLOR STAIN Dark Brown, Kuraray Noritake Dental) was added to the fissures (Fig. 13). For finishing, we used a multi-blade ball-shaped bur and an Arkansas Flame abrasive stone (Fig. 14). Polishing of the restorations was accomplished with the TWIST™ DIA system (EVE; Fig. 15). After rubber dam removal, the occlusal check was performed with articulating paper (Fig. 16), minimal adjustments were made and the surfaces repolished. The integration of the restorations after 30 days fully meets the clinical expectations (Figs. 17 to 20). Fig. 11. Glossy appearance of the cavities after application of the bond. Fig. 12.

Conclusion The innovative composite system CLEARFIL MAJESTY™ ES-2 Universal, which consists of two shades for the anterior and a single shade option for the posterior region, offers the properties needed for a successful implementation of the single shade technique. Used in the posterior region, the material is sufficiently opaque to mask optical irregularities of the underlying tooth structure, while it is translucent enough to provide for an imperceptible optical transition from the tooth structure to the restoration. Irrespective of the tooth shade, the restoration merges smoothly with the surrounding natural dentition, creating a harmonic overall picture. Dentist: DR.

News Feature Light diffusion technology – key to the success of your composite restorations 12 de out. de 2021 With CLEARFIL MAJESTY™ ES-2, the shade transition from composite to tooth is virtually invisible. The secret to this lies in light diffusion technology. How does this work? Before we discuss the technology in detail, here are some more information about our CLEARFIL MAJESTY™ ES-2 composites. All CLEARFIL MAJESTY™ ES-2 composites are suitable for both anterior and posterior applications. The different variants within the ES-2 family are characterized by supreme handling and a long working time, and the fact that they do not slump during modeling. A key feature of these composites is the ease with which restorations blend into their surroundings. This results in durable and aesthetic restorations. In CLEARFIL MAJESTY™ ES-2 composites, two types of fillers are used. Barium glass particles form the basis of the filler. Alongside this, advanced prepolymerized filler particles are added. The latter type is called light diffusion filler, since it is primarily these filler particles that achieve a light-scattering effect within the composite. The way in which a restoration 'adjusts itself', to the shade of the tooth to be restored, is not the same for all composites. Most composite manufacturers make use of the so-called 'chameleon effect'. A composite that is sufficiently translucent allows light to pass through. Light is reflected off the walls of the cavity, whereby the composite restoration assumes the shade of the adjacent tooth structure. In cavities that aren't too large with a sufficient amount of surrounding tooth structure, this chameleon effect works well enough. However, with larger cavities or in the absence of underlying tooth structure, as is often the case with anterior restorations, the aesthetic blending effect is limited. The brightness is far from satisfactory, and the restoration looks gray. At Kuraray Noritake Dental Inc., we do things differently. Besides the optimized translucency in CLEARFIL MAJESTY™ ES-2 composites, it's the light diffusion technology that makes the restoration blend seamlessly with the adjacent tooth structure. Thanks to the combination of these two parameters — translucency and light diffusion — the capabilities are far more extensive than with just translucency. The different dental tissues have different opacities. Enamel is more translucent than dentin. However, the degree of translucency/opacity of both tissues is not always the same. Age, thickness of the structure and various intrinsic and extrinsic factors all play a role. Depending on the desired end result, the most appropriate member(s) of the CLEARFIL MAJESTY™ ES-2 family is/are selected for the restoration. In aesthetic restorations in which opacity differences need to be considered, a layering system is necessary. More uniform restorations are easily constructed with a composite that has broad shade and opacity coverage. CLEARFIL MAJESTY™ ES-2 Premium for highly esthetic restorations. CLEARFIL MAJESTY™ ES-2 Universal for routine aesthetic restorations involving few or no opacity differences.
Clinical Cases Re-establishing a stable occlusion in a tipped second molar 5 de out. de 2021 Case by Dr. Salvatore Scolavino The establishing of a stable occlusal relationship is one of the biggest challenges dental practitioners are facing when restoring posterior teeth with resin composite, but it is a task with a decisive impact on the integrity of the masticatory apparatus. A poor static and dynamic occlusion may have a negative effect on the restored tooth, the periodontal apparatus, and also on the opposing dentition.1 Ideally, the occlusal anatomy of direct restorations is designed in a way that occlusal forces are directed along the long axis of the tooth, which is achieved when each cusp tip in occlusal contact touches a flat surface. Horizontally directed forces, on the other hand, should be avoided, as they tend to cause tipping and increase the risk of cuspal fracture, tooth mobility etc. In cases concerning improper occlusal relationship involving tipping of restored teeth, it may be possible to stabilize the situation by replacing the restoration and re-establishing a proper occlusion. If carried out correctly and early enough, this restorative approach may be a way around orthodontic treatment. The following clinical case is used to demonstrate how to create a functional occlusal surface right away – without larger adjustments. The whole restorative procedure is simplified by the use of a universal composite with a single posterior shade that eliminates the need for shade determination and shade selection, while it produces lifelike treatment outcomes. Case description This patient presented with direct composite restorations in the mandibular left first and second molar that were lacking an elaborated occlusal morphology (Fig. 1). The second molar appeared to be tipped mesially towards the first molar (Figs. 2 and 3), which resulted in improper occlusal relationships and a decreased position of the mesial marginal ridge. In order to verify the clinical and radiographic observation of an improper occlusal relationship, the occlusal contacts were recorded with articulating paper (Fig. 4). As expected, there was an uneven distribution of occlusal contacts, which were exclusively located in the distobuccal area on the second molar, and not matching the tooth-restoration interface on both molars. Fig. 1. Pre-operative clinical situation: Occlusal view. Fig. 2. Pre-operative clinical situation: Lateral view revealing the tipping of the second molar. Fig. 3. Pre-operative bite-wing radiograph confirming the tipping issue. Fig. 4. Checking of the occlusal contacts. Planned approach As orthodontic treatment was not an option, it was decided to replace the composite restorations, thereby treating the Class I cavity of the second molar as if it were a Class II cavity. This would allow us to increase the height of the mesial marginal ridge and establish the proper occlusion. Preliminary measures Once the rubber dam was placed (Fig. 5), the existing composite restorations were removed and the cavity slightly extended with a diamond chamfer bur (Fig. 6). The result of this procedure is shown in Figure 7. In order to provide an anatomical build-up of the mesial wall, a sectional matrix was mounted with the aid of a wooden wedge and a separator ring (Fig. 8). Fig. 5. Isolation with rubber dam, held in place with a clamp and a wedge. Fig. 6. Tooth preparation with a diamond chamfer bur. Fig. 7. Appearance of the teeth after preparation. Fig. 8. Sectional matrix, wedge and separator ring in place. Adhesive procedure After selective etching of the enamel (K-ETCHANT GEL, Kuraray Noritake Dental Inc.) (Fig. 9), the enamel bonding surfaces had a chalky-white appearance, which indicates properties that are favourable for bonding (Fig. 10). The adhesive procedure was performed with CLEARFIL™ SE BOND 2 (Kuraray Noritake Dental; Fig. 11). In the first step, the primer of the system was applied and actively rubbed into the surface for 40 seconds, and air-dried. Subsequently, the bond was used in the same manner. After complete evaporation of the solvent, the bonding surface was light-cured for 40 seconds to ensure proper polymerisation. The cavity floor was then covered with a 1 mm thick layer of flowable composite (CLEARFIL MAJESTY™ ES FLOW SUPER LOW A3, Kuraray Noritake Dental). Fig. 9. Selective etching of the enamel. Fig. 10. Chalky-white enamel surfaces. Fig. 11. Glossy appearance of the bonding surfaces after application of the tooth primer and bond. Restoration procedure Before starting to elevate the mesial wall of the second molar using the centripetal build-up technique2 (Fig. 12), we analyzed the height of the marginal ridge and anatomical details of the contralateral tooth, while the adjacent molar provided orientation as well. In general, knowledge not only about the tooth’s typical anatomy, but also about the patient-specific anatomical details of the adjacent and contralateral teeth as well as the antagonist is very useful for designing the occlusal anatomy. In addition, remaining anatomical structures should be read and used. In this particular case, the restorations were completed with CLEARFIL MAJESTY™ ES-2 Universal composite (Kuraray Noritake Dental) in the posterior shade U, using the cusp-by-cusp technique (Figs. 13 to 15). In most areas, it was possible to follow the inclination of the remaining cusps and the orientation of the grooves to produce an ideal surface anatomy. For those who would like to speed up the procedure, the simultaneous modeling technique3 may be an option. In this technique, the cusps are built up simultaneously from separate increments, which remain out of contact to each other until light-cured in a single curing cycle. Fig. 12. Mesial wall built up with composite. Fig. 13. Application of the first increment for cusp build-up. It is useful to limit the size of the increments for controllability. Fig. 14. Cusp-by-cusp build-up completed on the second molar. Fig. 15. Molars with restored occlusal surfaces. In order to improve the already great optical integration of the restorations, some stain (Dark Brown, CHROMA ZONE™ COLOR STAIN, Kuraray Noritake Dental) was applied to the fissures. A multi-blade ball shaped bur and an Arkansas Flame abrasive stone were used for finishing. Final polishing was accomplished with the TWIST™ DIA system (EVE). The immediate treatment outcome is shown in Figure 16. The patient was released after rubber dam removal, checking the static and dynamic occlusion, and conducting a control radiograph (Fig. 17). The optical integration was even better at the recall after one month due to the rehydration of the surrounding tissues (Fig. 18), while the functional integration was excellent and no occlusal adjustments were required. Fig. 16. Immediate treatment outcome with a nice optical integration of the restorations providing for a stable occlusal relationship. Fig. 17. Control radiograph taken after the direct restoration procedure. FINAL SITUATION Fig. 18. Treatment outcome at recall after 30 days. Conclusion The presented case example reveals how important it is to strive for occlusal stability when restoring posterior teeth with composite. Furthermore, it demonstrates how it is possible to re-establish a stable occlusal relationship, even if some tipping has already occurred. In order to get it right the first time, it is essential to make use of the remaining anatomical structures, which guide the way toward an occlusal surface that ensures a favourable distribution of occlusal forces, and therefore provides optimal conditions for a long life of the freshly restored teeth. The combined use of the presented restorative techniques with innovative materials like CLEARFIL MAJESTY™ ES-2 Universal will make the procedures simpler and even more efficient.
