Dentistry is currently experiencing an interesting evolution. While dentists are becoming increasingly specialised, the demand for products that can be used for all indications continues to grow. These systems and materials are part of a universal trend in dentistry—a trend that Kuraray Noritake Dental is extremely well suited to accommodate.

Advancing adhesive dentistry

As the technology has developed, dental adhesives have progressed from no-etching to total-etching and then self-etching systems. In 1978, Kuraray Noritake Dental introduced CLEARFIL™ BOND SYSTEM-F, the world’s first total-etching adhesive system. More than four decades later, the company is still setting standards with CLEARFIL™ Universal Bond Quick, a one-step dental bonding agent that can be used in total-etching, self-etching and selective-etching modes.

Combining Kuraray’s original MDP monomer with hydrophilic amide monomers, CLEARFIL™ Universal Bond Quick is designed to be less technique-sensitive than other one-step solutions and has been proved scientifically to deliver stronger, more stable bonds.

It is not just bonding agents that are becoming universally applicable either. A dental cement like Kuraray Noritake’s PANAVIA™ SA Cement Universal builds upon the success of previous generations of PANAVIA™ to deliver optimal bonding to dental tissue as well as to metal and zirconia materials. This self-adhesive resin cement always requires the same procedure, even when bonding porcelain, lithium disilicate and composites, without the need for a primer. The reason? It’s the addition of a unique long carbon chain silane.

Universal composites and cleaners

The silane technology behind PANAVIA™ SA Cement Universal can also be found in CLEARFIL MAJESTY™ ES Flow, a universal flowable composite suitable for all cavity classes. Its small, durable filler particles help to ensure excellent flexural and mechanical strength, while special cluster fillers provide a light diffusion effect similar to that of natural teeth. Creating aesthetically natural and reliable restorations is easier than ever with CLEARFIL MAJESTY™ ES Flow.

As the latest addition to the CLEARFIL MAJESTY™ ES series, CLEARFIL MAJESTY ES-2 Universal offers a smart and easy-to-use system that will work for the vast majority of your daily cases. Its light-cure, radiopaque restorative material which provides accurate color matching, high polishability and excellent physical properties, makes the product ideal for both anterior and posterior restorations. What makes this Universal series truly special is that the shades cover all shades of the VITA classical A1-D3 shade standard with a limited number of syringes/PLTs depending on the cavity class. If you opt for CLEARFIL MAJESTY™ ES-2 Universal, just a few shades will do the trick.

And when considering Kuraray Noritake’s forays into universal solutions, let us not forget the new KATANA™ Cleaner, a non-abrasive cleaner that, unlike other options on the market, can be used both intra- and extra-orally. Backed by extensive scientific research, the KATANA™ Cleaner comes with a single-handed delivery cap and an extremely straightforward method of application: simply apply with a rubbing motion for at least 10 seconds, rinse with water and air-dry before cementation.

Making dentistry more streamlined

The modern dental practice is often multidisciplinary in its nature, which can result in the need to store many more products than there might be space for. Through these universal products and others, Kuraray Noritake is aiming to make dentistry simpler and more efficient.

This case was conducted by Dr Davide Cortellini, owner of Studio Cortellini in Riccione in Italy, and dental technician Angelo Canale, owner of Canale dental laboratory in Rimini in Italy.

This patient came to the clinic to improve her chewing ability and aesthetic level. The physical examination revealed the presence of several endogenous erosive lesions that made chewing difficult, in addition to partly affecting the esthetics due to decrease in enamel thickness and the presence of dyschromic composite restorations. The possibility of using the new types of both tetragonal and cubic multilayer zirconia made it possible for us to plan the complete covering of all the elements with extremely conservative crowns with thicknesses between 0.5 and 1 mm in the axial and occlusal areas and up to 0.2 mm at the margin.

VERTICAL PREPARATIONS

Very conservative vertical preparations were carried out in the enamel without anesthesia. In the upper arch, the front group was prepared for full-veneer crowns, while the lower front group was treated with conventional lithium disilicate veneers without interproximal separation. In this case too, vertical preparations were carried out without finishing line. The impression was made using a 3Shape TRIOS intraoral scanner. The technician modeled the zirconia restorations that were then completed by the ceramist.

Knife Edge Preparation

SCANNING SEQUENCE

Digital DV models of temporary teeth

The three different materials were selected on the basis of the specific positions inside the mouth:

• UTML for the anterior teeth
• STML for the premolars
• HTML for the molars

The final result shows excellent integration between the 3 different types of zirconia and a good natural feeling.

MINIMAL PREP KATANA™ (KATANA™ MICRO LAYER)

HARMONIC OPTICAL INTEGRATION

The full-mouth rehabilitation procedure using three different types of zirconia led to a functional and beautiful treatment outcome. The optical integration between the materials is excellent and the high translucency especially in the anterior region creates a true-to-life appearance.

APPROACH WITH MINIMAL INVASIVE PREPARATIONS - REPORT ON THE SELECTION OF MULTI-LAYERED ZIRCONIA

Dental zirconia is no longer just the opaque framework material introduced two decades ago. Nowadays, it offers the high strength needed for long-span bridges, dentin-like translucency and strength perfect for thin-walled posterior crowns, or enamel-like optical properties for beautiful anterior restorations - depending on its composition and structure. Kuraray Noritake offers three types of dental zirconia - three with a multilayered structure created using patented powder coloring technology. They differ with regard to their optical and mechanical properties, which makes it possible to choose an ideal material for every clinical situation.

Zirconia, Oral scanner, feather edge preparation: the “winning triad”

The introduction of digital technology associated with the development of the latest zirconia materials offers the clinical and the dental technician a wide range of solutions to achieve aesthetics and function in a simple, predictable and above all conservative way. A further type of vertical preparation called "Minimally Invasive Vertical Preparation" has been introduced, applicable to numerous prosthetic clinical situations including cases of aesthetics. Minimally invasive vertical preparations, new type of zirconia and intraoral scanners represent a “winner triad” for today's prosthetic therapy.
