Case by Dr. Jusuf Lukarcanin

For all cases that require a particularly bright tooth shade – e.g. children or patients with bleached teeth / asking for a bleached effect in their restorations – CLEARFIL MAJESTY™ ES-2 Universal in the shade UW is likely to be the first choice. The young patient aged 28 shown below asked for diastema closure including shape and shade correction: She wanted to have a brighter, more beautiful smile.

Reasons for selecting universal white:

- Cases requiring a particularly high brightness or value

- Restorations in deciduous teeth

- Restorations in bleached teeth

Universal white properties:

- Well-balanced translucency

- High light-scattering effect

CONCLUSION

One universal composite, four shades: In the case of CLEARFIL MAJESTY™ ES-2 Universal, this portfolio is absolutely sufficient for single-shade restorations even in the aesthetically demanding anterior region. Properties such as a nice blend-in effect, a great polishability and gloss retention over time support dental practitioners in creating beautiful restorations. As shade determination may be based on very few criteria instead of a complex shade guide, the whole restoration procedure becomes less stressful and more efficient. Furthermore, with only four shades to stock and usually no blocker needed, the number of materials on stock is reduced, leading to facilitations in stock management as well.

Case by Dr. Jusuf Lukarcanin

In teeth in which the areas to be restored are surrounded by a lot of non-discoloured tooth structure - as may be the case in Class I, II and Class V cavities - the use of CLEARFIL MAJESTY™ ES-2 Universal in the shade U may be an option. The 28-year-old patient, who presented for diastema closure, had teeth with a comparatively low translucency and different shades due to smoking and excessive coffee consumption. As the composite was applied in enamel areas only, the relatively high translucency of the universal shade seemed beneficial in this case.

Reasons for selecting universal:

- Large amounts of underlying or surrounding tooth structure present

- Medium light-scattering desired

Universal properties:

- High translucency

- Medium light-scattering effect

Abrasion and shape correction was also the major reason for this 58-year-old female patient to ask for cosmetic dental treatment. She was unhappy with the appearance of the anterior teeth in the maxilla, which showed signs of tooth wear and discolouration. The selected treatment approach was composite veneering with CLEARFIL MAJESTY™ ES-2 Universal in the shade UD. The shade was selected based on the indication and the somewhat darker shade of the patient’s natural teeth.

Reasons for selecting universal dark:

- For older patients (tooth shades A3 and darker)

- Situations in which light easily passes through the composite (e.g., Class III, Class IV)

Universal dark properties:

- High light scattering effect

- Well-balanced translucency

Case by Dr. Jusuf Lukarcanin

This young patient aged 35 with microdontia presented in the dental office with the desire to have more beautifully shaped teeth. His teeth were almost free of dental caries, but with deficiencies in oral hygiene and signs of gingival inflammation. A deep bite was also evident. After professional tooth cleaning and oral hygiene advice, the teeth were restored with CLEARFIL MAJESTY™ ES-2 Universal in the shade UL.

4 Clinical cases by Dr. Jusuf Lukarcanin

Composites with a universal shade concept, a reduced number of shades that may be selected without any shade guide are a clear trend in restorative dentistry. With specific blend-in properties, these materials can help streamline restorative procedures and reduce chair time, take some pressure off the dental practitioner and contribute to potentially good outcomes. Some users, however, are skeptical about a wide-scale use of the materials, particularly when it comes to restoring teeth in the anterior region. The reasons may be a comparatively high translucency requiring the separate application of a blocker (or opacious shade) in certain situations, or a too limited shade offering.

Personal experience shows that CLEARFIL MAJESTY™ ES-2 Universal is perfectly suitable for a wide range of single-shade restorations in anterior teeth. It offers great polishability and long-term gloss retention and is available in just four shades: One universal shade (U) originally designed for posterior restorations, universal light (UL) and universal dark (UD) as the two major options for anterior teeth and, finally, universal white (UW) for the imitation of any bleached shade. In general, all four options may be used in the anterior and posterior region. As the blend-in ability is due to proprietary light-diffusion technology and not managed via an increased translucency, the application of a blocker is usually not necessary and even larger areas can be restored quite inconspicuously.

For those asking themselves when to select which shade in the anterior region, the following clinical case examples and comments may provide some useful guidance. The recommendations and practical tips are based on personal experience. All patients were in treatment for diastema closure or shape correction, but the selection criteria are the same for other types of anterior restorations, too.

UNIVERSAL LIGHT: FOR NATURAL RESULTS IN BRIGHTER TEETH

Restoring posterior cavities is a standard task we perform virtually every day. Yet, it is a challenging procedure as access to the affected teeth is often limited. This fact complicates many steps from working field isolation to material application and sculpting. By streamlining procedures and establishing protocols that are followed every time, it is possible to achieve predictable outcomes even in difficult situations, as shown below.

Direct resin composite restorations are a great option for diastema closure, shape correction and even an optical alignment of anterior teeth. The treatment approach is conservative with no or only minimal tooth preparation required, and with the right materials, it is possible to obtain beautiful outcomes, which is decisive in the aesthetically demanding anterior region. In this context, one might assume that a wide range of available shades and a meticulous shade selection process are important preconditions for a successful shade match. The following case examples show, however, that great outcomes can also be achieved in a simplified way using CLEARFIL MAJESTY™ ES-2 Universal, a game-changing resin composite with only two shade options for the anterior region.

Apart from the fact that the procedure is simplified be eliminating the need for shade determination and selection, the workflow is the same as with traditional composites.

„My first reaction to this material was: this is a Game-Changer.“

The results are magical. Smoother and easy handling properties, high-gloss, natural light distribution and the process is simple. Aside from being able to skip the shade selection step, your workflow remains the same as with traditional composites. At first, I might have been a little skeptical about replacing all the different shades of composites we use in office every day. But after a couple of tries I discovered that it indeed works every time, in most cases even without the use of a blocker. Simply ingenious!

Is it possible to fulfil high aesthetic demands by restoring anterior teeth with composite resin? It is – provided that several important factors are respected. One of these factors is the faithful reproduction of the natural tooth morphology, which has a decisive impact on aesthetics and function. Moreover, success is determined by the selection of the right shades of high-quality composite resin and their purposeful combination using proper layering techniques.

Introduction

The aesthetic appearance of direct anterior restorations is affected by proper shade selection on the one hand and the creation of a natural shape and texture on the other¹. Hence, the dental practitioner’s own artistic skills play a decisive role. According to Fahl, information about the tooth morphology and function, and the optical properties of the tooth should be taken into consideration when the most suitable restorative material and shade are selected².

These minimally invasive composite restorations are no longer a temporary solution for the anterior region. Instead, they are regarded as an adequate alternative to indirect restorations, as they are both durable and able to closely imitate the natural tooth structure³⁴.

Clinical case example 1

This 45-year-old female patient presented with a diastema and a disproportion in the size and shape of her maxillary central incisors (Fig. 1). In the first step, a detailed case history was taken and an intra-oral examination was carried out. Subsequently, the initial situation was recorded by taking intra-oral photographs, which would allow for a computer-aided morphological evaluation and treatment planning (Fig. 2).

Fig. 1: Pre-operative image.

Fig. 2: Digital mock-up.

The patient’s second visit started with a professional tooth cleaning procedure followed by isolation of the maxillary anterior teeth. Afterwards, the tooth shade was determined and appropriate composite shades were selected. In this case, the shades A2E, Amber Translucent and A3D of CLEARFIL™ Majesty ES-2 Premium (Kuraray Noritake Dental, Japan) appeared to be most suitable. In addition, a mock-up was created using mock-up resin in order to produce a silicone key.

Opting for a minimally invasive procedure, no mechanical tooth preparation using drills was performed after removal of the mock-up. Instead, the enamel was merely etched with 35% phosphoric acid gel (K-Etchant, Kuraray Noritake Dental) to increase the surface roughness. After rinsing and drying, the adhesive agent (CLEARFIL™ Universal Bond, Kuraray Noritake Dental) was applied to the etched surfaces. Composite layering started with the build-up of palatal shells with the aid of the silicone key. Following light-curing of the shells, a small amount of composite in the dentin shade A3D was applied to the proximal surfaces using a thin spatula and a brush. The aim was to reduce light transmission in the area of the dentin core. The restoration was completed with a combination of the composite shades A2E (enamel) and Amber Translucent, which were applied using a modeling brush.

Finishing and polishing was accomplished using flexible rubber polishing discs containing diamond particles (CLEARFIL™ Twist DIA, Kuraray Noritake Dental) with a low-speed handpiece. No additional finishing and contouring was necessary due to the use of a brush during layering, which ensured the creation of a natural shape and surface texture. Figure 3 shows the outcome of the restoration procedure.

Fig. 3: Treatment outcome immediately after polishing.

Oral hygiene training was provided and follow-up examinations were performed after three, six and twelve months (Fig. 4). Healthy hard and soft tissue conditions were observed during these visits.

Fig. 4: Clinical situation at the one-year recall.

Clinical case example 2

This 30-year-old female patient had a diastema, irregularly shaped anterior teeth and showed signs of abrasive tooth wear (Fig. 5). Following a detailed anamnesis and intra-oral examination, the tooth shade was determined and the composite CLEARFIL™ Majesty ES-2 Premium selected in the monochromatic shade Universal A1.

Fig. 5: Pre-operative clinical situation.

Following the isolation of the working field, 35% phosphoric acid etchant (K-Etchant) was applied to the enamel of all teeth between the maxillary right canine and the maxillary left first molar. The surfaces were then treated with a universal bonding agent (CLEARFIL™ Universal Bond) as recommended by the manufacturer. Modeling was carried out with a thin spatula and a modeling brush for composite. Neither a silicone key nor any wetting or modeling resin were used in the procedure. For polishing, the flexible polishing discs CLEARFIL™ Twist DIA were used at low rotational speed. Thanks to the use of the modeling brush, no additional finishing with diamond-coated instruments was necessary. Figures 6 and 7 show the final restoration at baseline and one week after completion of the treatment.

Fig. 7: Clinical situation after one week.

This patient also received oral hygiene training and presented for recalls three, six and twelve months after the treatment. The patient maintained an exemplary oral hygiene behaviour, so that it came as no surprise that the soft tissues were healthy and the restorations were in a perfect condition after one year (Fig. 8).

Discussion

Nowadays, direct composite restorations are becoming increasingly popular. Especially for young patients and all those who do not want to sacrifice large amounts of healthy tooth structure, the technique is an ideal treatment option⁵. In many cases, aesthetic outcomes are possible without mechanical tooth preparation, but a selective etching procedure only⁶.

The clinical lifetime of these restorations depends on many factors. Important prerequisites for high-quality outcomes include the selection of a suitable composite material with the required surface hardness, appropriate finishing and polishing, a good oral hygiene behaviour, and proper maintenance measures during periodical follow-up visits. As a matter of course, the manual skills of the dental practitioner and the use of selected materials according to the manufacturer’s instructions for use also have a direct impact on the long-term success of the restorations⁷⁸⁹. A user’s inability to meet one of these requirements and failure to carry out all working steps correctly may have a direct impact on the quality of the restoration.

Conclusion

Composite resin is a popular material class for the production of aesthetic anterior restorations die to their straightforward use and rapid application, good repair options and high aesthetic potential when used properly . The two case examples illustrate that a treatment with composite resin is often the best treatment option when a non-invasive procedure completed within a single visit is desired.
