Steve Meeze: Passion for Dentistry

Steve Meeze on the passion for dentistry

Steve Meeze definitely has it: a passion for dentistry. Yet, there was a time when he was unhappy in his job as a dental practitioner. Fundamental changes were necessary to lay the foundations for finding personal fulfillment in his work. We spoke to him about his motivation to do things differently and about the path he has chosen and is following down to the present day.

 

Many students of dentistry would like to run their own dental office one day. For you, this dream came true, but you ultimately decided to take a different path. Why did this change seem necessary?

 

After graduation in 1983, running my own dental office seemed to be a great plan: I wanted to be independent, grow my patient base, and become successful, which went very smoothly in the beginning. This economic success, however, did not protect me against starting to feel unhappy and burned-out after several years. Once I began to take my negative emotions seriously and to search for the underlying causes, I realized that is was not merely the workload that troubled me. The truth was that I was missing a sense of purpose in many of my daily tasks. This seemed to be the reason for my lack of energy and motivation to proceed with what I had started. Luckily, I was able to find my personal “why” after some time.

 

Where did you find your own fulfillment or sense of purpose?

 

I ultimately found it in the field of conservative dentistry. The reason is that direct restorative treatments with composite allow me to do amazing things in a non-invasive or minimally invasive way. Doing no harm and always being able to go back simply feels good, and my patients are incredibly grateful for what I do. Their gratitude is my reward. This is why I decided to dedicate myself exclusively to treating patients with composite.

 

How do you do this?

 

In 2009, I sold my own dental office and started working in different practices in Flanders. In this process, I established some highly valuable partnerships with colleagues, who appreciate my skills and refer their patients to me mainly in the course of interdisciplinary treatment. These orthodontists or surgeons need someone who puts the finishing touches to their work. And this is exactly what I do: I create a beautiful smile at the end of an often complex treatment. Other patients approach me on their own accord with fractured or misshaped teeth and the desire for esthetic improvement. In any case, I listen to them carefully before I start planning. Knowing what is on their minds, I can treat them with confidence. The most precious moment for me is when I hand over the mirror and let them evaluate my work. Their positive reaction, the glint in their eyes is what motivates me every day.

 

Is there a specific technique you use in your daily work?

 

Yes, I use the Light Facing Concept I developed to solve esthetic issues in the anterior region. This technique focuses of creating a harmony without the need to sacrifice large amounts of healthy tooth structure. With this concept, a fractured anterior tooth, for example, is restored in three steps: Initially, a single dentin shade of composite of the same color as the fractured tooth is used to create the desired tooth shape and make the fracture line disappear. In this step, shade selection is independent of the final color I would like to reach. Subsequently, I correct the color with an opaque material and try to match the shade of the adjacent teeth as exactly as possible. If necessary, I create mamelons and other individual characteristics in this layer. The final step is carried out on all anterior teeth whenever the appearance of the treated tooth differs from the others: A light facing – i.e. a very thin layer of more or less translucent composite – is added to mask the differences. In cases with minimal shade differences, a composite with a high translucency is used, while a more opaque material is preferable whenever the differences are more apparent.

 

What is your preferred material for the Light Facing Concept?

 

My personal experience shows that the best results are obtained with CLEARFIL MAJESTY ES-2 Premium composite from Kuraray Noritake. It simply offers the best mimetic (chameleon) effect of all composite materials I have tested so far, and I have tested many of them. The material tends to blend in with the surrounding tooth structure, and only four shade combinations are usually sufficient to cover the whole range of my patients’ tooth shades. I love this virtually magical effect!

 

What is your personal conclusion?

 

When I made the decision to start doing what really makes me happy, I could not be sure that I had chosen the right path. Retrospectively, I know that giving up my present career and taking steps towards personal fulfillment has been exactly the right thing to do. I love the fact that I can satisfy my patients’ desires without sacrificing healthy tissue, and my Light Facing Concept implemented with MAJESTY ES-2 make it easy for me to obtain the results they have been dreaming of.

Kiyoko Ban, Technical Consultant at Kuraray Noritake Dental, talking about the development of Noritake Super Porcelain AAA. The product

An interview with Ms. Ban - 30 years of dental ceramics development.

The development of ceramic dental materials has a long tradition at Noritake Co., LIMITED (Noritake). It started in 1978, when Kiyoko Ban, who is a Technical Consultant at Kuraray Noritake Dental today, was a member of the teaching staff at the Tokai College of Dental Therapy in Nagoya, Japan. There, she trained her students in producing porcelain-fused-to-metal (PFM) restorations, and encountered the problem of porcelain fractures and cracks that often occurred after the firing process. Her desire to solve this problem resulted in the first dental porcelain development project at Noritake.
Image 1: Kiyoko Ban, Technical Consultant at Kuraray Noritake Dental, talking about the development of Noritake Super Porcelain AAA.

Failure analysis
Kiyoko Ban gives an account of her early activities: “I received many inquiries from dental technicians on why cracks occurred inside veneering porcelains of PFM during firing. I wanted to find out what was causing this problem. Hence, I started analyzing the available materials and manufacturing procedures. In the course of my research, I concluded that in order to obtain better results, it would be necessary to develop a new porcelain material with fundamentally different physical properties. The reason was that the physical properties of the
available porcelain materials were unstable. One problem was that the coefficients of thermal expansion of the porcelain were changing under varying firing conditions, and sometimes fluctuated even if the firing temperature remained constant. Due to the differences in the coefficients of thermal expansion of the metal framework and the veneering porcelain, high stresses inside of veneering porcelain were generated, which ultimately led to the observed cracks.”

Joining forces with Noritake
For support in her research, Kiyoko Ban approached a leading expert in the measurement of residual stress in ceramics, Dr. Hiroshi Inada. He was the Manager of the Research & Development Department at Noritake. Together, they decided to initiate a
joint development project. In the first phase, the market research was conducted in order to define the project aims. “We found that there were three factors that troubled dental technicians fabricating PFM restorations: cracks and fractures in the porcelain layer, limited reproducibility of the natural tooth colors and yellowish discoloration caused by silver in the framework material. Consequently, we decided to develop a crack-free material that was resistant to yellowish discoloration and matched the colors of natural teeth by offering a tooth-like fluorescence,” states Kiyoko Ban. She continues: “The first steps in the development process were relatively easy. We soon were able to ensure constancy of the coefficient of thermal expansion. The most complicated part, however, was to develop different material shades. As understanding and reproducing tooth color is a highly complex task, we collaborated with dentists and dental technicians. They evaluated the optical properties of our trial formulations and helped us improve them until they were satisfied with the outcomes. This process took us three years and finally resulted in the 16 material shades launched in 1987.”

Image  2: The product launched more than 30 years ago: Noritake Super Porcelain AAA.

The name – Noritake Super Porcelain AAA – was suggested by the former Vice President of Noritake and at that time Managing Director, Motoki Nawa. It refers to the three basic needs it satisfies, and expresses that the product aim for becoming class A. Noritake Super Porcelain AAA became available in Japan, where Morita Corporation became the distributor. Soon, a network of instructors was established and training courses were offered to ensure technicians would use the product in the best possible way. Within a very short time, the product got a market share of approximately 30 percent. At this time, Noritake Super Porcelain AAA also started to conquer overseas markets (where it was given the product name Noritake Super Porcelain EX-3). Until today, many dental technicians around the world favor the porcelain material.

Additional shading options
One of the instructors who taught the use of the material worldwide was Hitoshi Aoshima, a representative of Perla Aoshima. He was famous for his excellent technique in the fabrication of porcelain restorations. Kiyoko Ban approached him at the 15th anniversary symposium of the international journal of dental technology in Tokyo in 1988, and initiated what would soon become a fruitful collaboration: “I decided to visit him in his laboratory soon after our meeting and provided him with a complete Noritake Super Porcelain AAA kit. One month later, during my second visit, he suggested developing porcelain stains, which do not generate air bubbles during the firing process even when you stain inside the veneering porcelain. This would enable dental technicians to imitate the complex color of natural teeth easily. We started working on the project immediately. With the support of Hitoshi Aoshima, our efforts came to fruition, resulting in the introduction of the product Internal Live Stain.”

Eyeing the next step: Research into zirconia
With the growing interest of dental technicians in porcelain materials, Kiyoko Ban was moved to predict that in the future, ceramics would evolve to become the preferred restoration material. She began investigating suitable ceramics and mmanufacturing technologies. In November 1998, Noritake’s Development Division and Noritake Dental Supply initiated a joint project to develop a new dental zirconia. “As a ceramics company with 15 years of experience in the field of industrial zirconia, Noritake foresaw that zirconia was going to be the next leading dental material. Consequently, we started developing the raw materials. Thanks to our high level of know-how in ceramic materials, we were soon able to present a new dental zirconia having less deformed after sintering. We observed the material trends and market needs for a while, and finally decided to go for finer esthetic properties and develop multi-layered disc. The product – KATANATM Zirconia ML – was introduced at the International Dental Show 2013 in Cologne, where it made a spectacular debut. The product received worldwide recognition. Today, three variants of the multi-layered discs are available. They offer different levels of flexural strength and translucency to meet the requirements oof various clinical situations.

Towards the future
More than 30 years after its launch, Noritake Super Porcelain AAA is still the product of choice for many ceramists around the globe. “With satisfied users in approximately 100 countries, I am happy to conclude that we have succeeded in developing a PFM porcelain that is virtually trouble-free,” says Kiyoko Ban. “Due to the success of the development projects, so far, in the field of dental ceramics, we are highly motivated to keep on developing new products that satisfy the needs of dentists, dental technicians and patients alike.” Kiyoko Ban, Kuraray Noritake Dental’s Technical Consultant, is still working hard to help enhance treatment outcomes in dentistry and contribute to an improvement of oral health.

“Simply apply and dry, and you’re done”: CLEARFIL™ CERAMIC PRIMER PLUS

Combining ease of use and excellent viscosity, CLEARFIL™ CERAMIC PRIMER PLUS is a stable and universal prosthetic primer designed for all restorations. By incorporating Kuraray Noritake Dental’s original MDP monomer and a silane monomer, it is able to provide an enhanced adhesive surface for ceramics, hybrid ceramics, composites and even metals. CLEARFIL™ CERAMIC PRIMER PLUS is best used in conjunction with the adhesive resin cement PANAVIA™ V5 to ensure durable restorations.

 

The key to CLEARFIL™ CERAMIC PRIMER PLUS’s performance is in the monomers it possesses. The MDP monomer strongly bonds to metals and zirconia, while the silane coupling agent MPS efficiently adheres to composites and all silica-based ceramics. “What makes CLEARFIL™ CERAMIC PRIMER PLUS different to other primers is its stability,” says Peter Schouten, Technical Manager at Kuraray Noritake Benelux. “Normally, activated silanes are very unstable. However, the well-balanced formula of CLEARFIL™ CERAMIC PRIMER PLUS provides it with a shelf life of three years after production, making it easy and predictable to use.”

 

Procedural simplicity

Every element of CLEARFIL™ CERAMIC PRIMER PLUS is designed to deliver maximal procedural simplicity. It is packaged in an easy-to-squeeze bottle that dispenses the solution easily and accurately. Whereas other similar products need to be left in place for one minute or more, this primer is immediately effective upon application. “CLEARFIL™ CERAMIC PRIMER PLUS benefits the dentists by offering a reliable primer for all materials, without being difficult to apply or use,” says Schouten. “From titanium to zirconia, from lithium disilicate to composite—simply apply and dry, and you're done.”

 

PANAVIA™ V5

A resin cement with unrivalled procedural simplicity and predictability, PANAVIA™ V5 is a member of Kuraray Noritake Dental’s PANAVIA family. It sets a new standard for adhesion, allowing for self-cure dentine bond strengths equal to our gold-standard light-cure bonding agent, CLEARFIL SE BOND. PANAVIA™ V5 offers natural aesthetic stability in shading through its amine-free paste, which is available in five shades and has been scientifically proven to demonstrate a lower level of post-curing colour variance than amine-based cements.

 

CLEARFIL™ CERAMIC PRIMER PLUS and PANAVIA™ V5

Providing strong bonding to not just hydroxyapatite, but to metals and zirconia as well, PANAVIA™ V5 is designed for use in conjunction with CLEARFIL™ CERAMIC PRIMER PLUS. The cementation procedure is efficient and effective: use PANAVIA V5 Tooth Primer for the pretreatment of the tooth, CLEARFIL™ CERAMIC PRIMER PLUS for the priming of the restoration, and PANAVIA™ V5 for the cementation.

 

Easy cementation with KATANA™ Zirconia Block - interview Dr. Alexandre Pereira Monteiro

In 1983, Kuraray introduced the patented MDP monomer in its PANAVIA™ EX cement. 35 years later, MDP monomer-based resin cements have been scientifically proven to provide the most favourable bond values when cementing zirconia. With the recent introduction of the all-ceramic KATANA™ Zirconia Block, cementation is still best achieved with the PANAVIA and CLEARFIL families of products.

 

Cementation to zirconia

The KATANA™ Zirconia Block possesses a tooth-like translucency and impressive flexural strength, making it a preferable option to lithium silicate glass. For strong and reliable bonding to the existing tooth structure, it is best to use PANAVIA™ V5 Tooth Primer for the pretreatment of the tooth and CLEARFIL™ CERAMIC PRIMER PLUS for the priming of the restoration. Since both of these utilise MDP monomer technology, you can be assured of easy adhesion with the PANAVIA™ V5 system.

Kuraray Noritake offers full-adhesive cementation with PANAVIA™ V5 and self-adhesive cementation with PANAVIA™ SA Cement Plus. Both products are designed for durable cementation of zirconia-based restorations with unparalleled procedural simplicity and predictability. PANAVIA™ SA Cement Plus also incorporates a high concentration of MDP monomer to offer increased chemical reactiveness and adhesion with zirconia.

 

A dentist’s perspective

Dr Alexandre Pereira Monteiro is a dentist who runs his own implant surgery practice in Cessy in France. Dr Pereira’s interests, though varied, lie primarily in aesthetic and CAD/CAM dentistry, and he has used the KATANA™ Zirconia Block since 2018. “I think these new ranges of zirconia have many advantages,” he says. “They combine aesthetic properties with translucency parameters similar to those of lithium disilicate glasses with a much higher resistance to bending and abrasion.”

For cementing restorations made with the block, Dr Pereira likes to use PANAVIA™ V5. “As a user of many adhesive systems, I know PANAVIA™ V5 very well,” he says.

“PANAVIA™ V5 has the benefit of being a system that is very polyvalent in its indications while also being very tolerant. It offers a simple, unique and easily reproducible protocol that will satisfy the majority of practitioners. Special mention must be made of the opaque version, as it is very effective for hiding a metal structure or a strongly dyschromatic tooth.”

KATANA™ Zirconia Block possesses excellent mechanical properties

Manufactured from Kuraray Noritake Dental’s proprietary zirconia powder, new KATANA™ Zirconia Block delivers aesthetic, natural-looking restorations. However, it is not only aesthetic value that this all-ceramic solution provides. Its superior mechanical properties were designed for reliable, repeatable fabrication of full-contour prostheses.

 

Impressive flexural strength

The multi-layered KATANA™ Zirconia Block possesses a flexural strength of 763 MPa, which is far higher than that of lithium silicate (LS) glass-based ceramics. This means that restorations made with the KATANA™ Zirconia Block can be designed to have thinner walls than those made with LS glass. This has now resulted in great mechanical properties and beautiful aesthetics that are now possible for all single-unit anterior and posterior restorations.

 

Fast chairside processing

Thanks to its integration with Dentsply Sirona’s CEREC® CAD/CAM system and SpeedFire™ ovens, the KATANA™ Zirconia Block is perfect for chairside processing and the fabrication of prostheses. Dentists only require 15 minutes for dry milling a crown with the CEREC milling unit and an additional 18 minutes is required for the sintering of the block.

 

A highly precise material

Dr Hendrik Zellerhoff runs a dental practice in Laer, located in the North Rhine-Westphalia district of Germany. As a digital dentistry and CEREC specialist, he has used the KATANA™ Zirconia Block for more than 40 cases in his practice since March 2018 and praises its perfect balance of aesthetics and mechanical performance. “Its strength is a major advantage—the bend strength totals 763 MPa,” says Dr Zellerhoff. “This means that it can even be used to create extremely thin walls, which in turn means minimally-invasive work. In addition, the margins are even more slender than on glass ceramics.” 

 

Due to the fact that zirconia shrinks to the final size during the sintering process, an approximately 25 per cent oversized restoration needs to be milled out,” continues Dr Zellerhoff.

 

“This is executed using very fine milling cutters. Therefore, a larger workpiece is processed using smaller instruments. This leads to high-precision margins and occlusal surfaces. Only after this does dense sintering take place. The exact shrinkage factor is stored in the barcode on the block. Almost no rework is required in the occlusal or approximal areas. We even do without a try-in after sintering—we glaze immediately. This fact alone is really fascinating, even for long-standing, ‘pampered’ CEREC users.”

Light diffusion in composites

An important aspect of a direct composite restoration is aesthetics. Choosing the right opacity, chroma and value is an absolute necessity for natural-looking results. However, working with a composite with built-in light diffusion technology will make life much easier. Due to this technology, a composite can blend seamlessly with the adjacent tooth structure.

 

What is light diffusion?

Simply put, light diffusion refers to a material’s ability to scatter and reflect light rays in many different angles. Composites without a form of light diffusion technology are less forgiving and that’s why preparation borders are still often visible through the composite. Alternately, a composite can be so opaque that the filling often stands out from the tooth tissue. With aesthetic composites, the ability to diffuse light in all directions, in a way that emulates these natural teeth, is crucial to their success. With the help of Kuraray Noritake Dental’s Light Diffusion (LD) technology—which incorporates light diffusion particle fillers to augment the opacity of restorations—our CLEARFIL MAJESTY family of composites can do just this.

 

The CLEARFIL MAJESTY family

Both CLEARFIL MAJESTY ES-2 Premium and Classic, as well as CLEARFIL MAJESTY ES Flow, faithfully reproduce the diffusive properties of tooth structure. This means that they show a higher level of light diffusion in the more opaque shades (dentin) and a lower level in the more translucent ones.

 

The actual effect of our LD technology can be clearly seen in the following images. On the laminated Light Diffusion Card there are three discs, each made of a composite material less than 1mm thick. The composite on the left (the CLEARFIL MAJESTY Esthetic) is the most translucent of the three when the card is placed directly on top of another surface—this composite best allows the text to be read through it. However, increasing the distance from the text by inserting a pair of two-euro coins underneath the card reverses this outcome—thanks to the light diffusion properties of CLEARFIL MAJESTY Esthetic, it is the only composite through which the text can no longer be read.

 

When put into practice, the end result is simple: this light diffusion helps create a restoration that merges effortlessly with the surrounding natural dentition. 

Kuraray Noritake highlights KATANA Zirconia Block at Berlin symposium

Kuraray Noritake highlights KATANA Zirconia Block at Berlin symposium

 

Berlin, Germany: Kuraray Noritake Dental invited dental professionals from across Europe on January 26 to a symposium dedicated to the KATANA Zirconia Block, the newest addition to its famed KATANA Zirconia range. Held in the Lecture Hall Ruin of the stunning Berlin Museum of Medical History, the symposium brought together leading experts to discuss their research and clinical experiences with the material so far.

 

Prof. Florian Beuer, Chairman of the Department of Prosthodontics at the Charité University of Medicine in Berlin, welcomed the attendees and guided them through the history and development of zirconia as a dental restoration material. Beuer emphasised the vast difference between the first generation of zirconia, which was relatively opaque and prone to chipping and fracturing, and the highly translucent, mechanically superior zirconia of today. “Today, zirconia is truly applicable for digital workflows,” he stated, highlighting that its ability to be used for single-unit restoration and minimally invasive dentistry “truly helps to save the existing tooth structure”.

 

The morning’s other sessions focused on material research regarding the mechanical and aesthetic properties of the KATANA Zirconia Block. Prof. Marc Schmitter discussed the mechanical properties and fracture toughness of occlusal veneers made with the block in comparison to lithium disilicate, whilst the University of Bologna’s Prof. Paolo Baldissara highlighted the use of Kuraray Noritake’s multilayered zirconia technology, which allows it to effectively mimic the shade gradation of natural teeth. Prof. Cees Kleverlaan also presented his work on tooth enamel erosion, concluding that restorations made with ceramics such as zirconia generally lead to far lower wear rates than those made with materials with large, hard particles and low filler loads.

 

After a hearty lunch that featured falafel and currywurst – a Berlin sausage-based specialty – a variety of highly renowned experts in dentistry took to the stage to present their clinical experiences with the KATANA Zirconia Block. President of the ISCD (International Society of Computerized Dentistry) Dr. Klaus Wiedhahn went through his experiences integrating the block into his CEREC-based digital workflow, stating that “with the KATANA Zirconia Block, aesthetics are no longer a weak point”.

 

Drs Nicola Scotti, Rodolphe Acker and Hendrik Zellerhoff then presented their own clinical experiences with this new product in Italy, France and Germany, respectively. Each dentist commented on how the speed with which the block can be milled and sintered with the CEREC system allowed them to see how full-contour zirconia restorations can now be considered to be a true chairside solution. “Thanks to this block, you can create something really amazing without much effort,” said Scotti, who only began using it in April 2018 but was soon impressed with the block’s aesthetic qualities and ease of cementation with PANAVIA V5.

 

Dr. Alessandro Devigus and MDt. Daniele Rondoni, two active members of the European Academy of Esthetic Dentistry, capped off the symposium by discussing the possibilities of the KATANA Zirconia Block for restorations in the aesthetic zone. Both dentists emphasised the importance of fluorescence in this regard and showed, through a number of clinical cases, that the block’s excellent translucency and impressive shade selection make it ideal for this purpose.

 

Overall, the symposium effectively demonstrated the potential of Kuraray Noritake Dental’s KATANA Zirconia Block as a material for single-visit chairside restorative dentistry.

Create natural gloss instantly with CLEARFIL MAJESTY™ ES Flow

An ideal composite material should satisfy three basic requirements: function, aesthetics and biocompatibility. A member of the CLEARFIL MAJESTY family, Kuraray Noritake Dental’s CLEARFIL MAJESTY™ ES Flow combines excellent handling, polishability and mechanical strength to provide a solution for all cavity classes. This universal flowable composite employs silane and filler technologies to maximise both its procedural and aesthetic outcomes, allowing dentists to create long-lasting restorations with reduced chairside time.

 

A new standard for flowable composites

Traditionally, a composite’s flowability has been inversely related to its filler content. When flowable composites were first introduced in the mid-1990s, their lower viscosity was enabled by a filler level much lower than that of conventional composites. This, however, meant that these flowables fared poorly in a clinical setting, demonstrating inferior mechanical properties when compared to traditional hybrid composites.

 

With CLEARFIL MAJESTY™ ES Flow, dentists can now use a flowable composite with mechanical properties comparable to those of conventional alternatives. Thanks to Kuraray Noritake Dental’s silane technology, millions of submicron filler particles fit into the composite, reliably adhering to the resin and maintaining long-term stability. CLEARFIL MAJESTY™ ES Flow possesses a scientifically tested flexural strength of over 150 MPa, similar to that of a universal nano hybrid composite, making it suitable for use in Class I and II restorations.

 

Aesthetic restorations

However, the small, durable particles of CLEARFIL MAJESTY™ ES Flow provide more than just mechanical reliability. Special cluster fillers provide a light diffusion effect that is similar to that of natural teeth, meaning that the material blends effortlessly with the existing tooth structure. Unlike other flowables, CLEARFIL MAJESTY™ ES Flow is glossy immediately after curing. This gloss can be improved with remarkable simplicity—simply wipe the cured resin with an ethanol-moistened gauze or cotton roll to produce a smooth surface that is proven to maintain its gloss over time.

 

Ideal handling

CLEARFIL MAJESTY™ ES Flow’s low viscosity monomers ensure that it has excellent handling characteristics, promising better sculpting for the dentist. The flowable composite does not stick to the needle tip or to any instruments, only adhering to the area to which it is applied, while the proprietary design of the syringe itself minimises air bubbles when dispensing. Once dispensed, the paste possesses great consistency with its non-slumping formula, ensuring that it can maintain its shape. A truly universal composite, CLEARFIL MAJESTY™ ES Flow allows dentists to create highly aesthetic restorations with ease.

 

Obtain results in four simple steps

Creating aesthetic and durable restorations has never been more achievable. Simply prepare the cavity and apply bonding, dispense and sculpt the CLEARFIL MAJESTY™ ES Flow, light-cure and, finally, polish. It’s as easy as that.
