PUTTING CERABIEN™ MiLai TO THE TEST

Nowadays, lithium disilicate and highly translucent variants of zirconia are among the most popular ceramic materials processed in the dental laboratory. Their favourable optical properties allow us to opt for simplified finishing approaches such as micro-layering in a great majority of cases. For dental technicians, this means a reduction of the manual workload without compromising the quality of the outcomes.

Recently, Kuraray Noritake Dental Inc. has launched a new set of porcelains and internal stains specifically developed for micro-layering, which works not only with zirconia but also with lithium disilicate. The CERABIEN™ MiLai line-up consists of 16 porcelains and 15 internal stains, which – the manufacturer claims – are easy to select and manage. As the more universal approach with a single porcelain for silicate ceramics and zirconia enables us to streamline inventory management and to standardize layering procedures, we decided to test the new product in the laboratory setting. The following case is a documentation of the first try of CERABIEN™ MiLai on lithium disilicate (Amber Press, HASS Bio).

CONCLUSION

The outcome achieved at the first go with the CERABIEN™ MiLai line-up for micro-layering on lithium disilicate is very satisfying. I feel that we can achieve great results with this system, which is indeed easy to select and manage. The reduced number of shades clearly comes in handy especially for beginners, who will be grateful for the option of creating lifelike restorations with fewer decisions to be made, and less effort involved compared to conventional ceramic line-ups. The possibility of standardizing and streamlining procedures by using a single porcelain system for all micro-layering procedures is likely to improve the life of every dental technician.

Clinical case by Kostia Vyshamirski, DT

Digital technologies for computer-aided imaging, planning, design and manufacturing are valuable tools that support dental technicians in their daily work. Combined with traditional approaches, those digital tools allow us to assess, shape, and finally meet or even exceed patient expectations. The case below is a perfect example: We produced 20 natural bleach restorations made of KATANA™ Zirconia YML and CERABIEN™ ZR Porcelains and of Noritake Super Porcelain EX-3 (Kuraray Noritake Dental Inc.), respectively.

INITIAL SITUATION

The aim was to create a new white, still natural smile. It was decided to replace the old crowns in the maxilla and to create a wider and brighter smile by adding laminate veneers in the maxilla and mandible.

Fig. 1. Initial clinical situation.

DIGITAL SMILE DESIGN AND DIAGNOSTIC WAX-UP

Digital smile design and a diagnostic wax-up are great tools for analysing and planning a new smile. Intraoral scans and portrait photographs of the patient served as the basis for the development of the ideal proportions and shapes. Once the virtual designing of the new restorations was completed (software: exocad DentalCAD), the wax-up models were printed. By transferring the wax-up into the patient’s mouth via an index or matrix, it is possible to test and assess the outcome intraorally. In this step, aesthetic and functional analysis should be the priority.

Fig. 4. Completed virtual wax-up for the maxilla and mandible.

Fig. 5. Wax-up transferred into the patient’s mouth for functional and aesthetic analysis.

Fig. 6. The planned new bright smile.

ALVEOLAR PRINTED MODEL

Precise and functional models are essential for the production of accurate, aesthetic restorations in the laboratory. The model builder software SHERAeasy-model (SHERA) and a 3D printer (ASIGA MAX UV, Asiga) were used to produce solid models and alveolar models with full gingival information and removable dies.

Fig. 7. Alveolar models printed in gingiva and tooth colours.

Fig. 8. Printed models with articulator holding plates and removed dental elements.

REFRACTORY DIE DUPLICATION AND ARTICULATION

The refractory die technique allows for the production of extremely thin-walled restorations and hence supports minimal tooth structure removal. For this reason, the approach seems best suited for all previously untreated teeth without major defects. The printed dies were duplicated in the refractory die material before mounting the models in the articulator for a transfer of the maxillomandibular relations.

Fig. 9. Process of duplicating printed dies in the refractory material.

Fig. 10. Articulating the models.

PRODUCTION OF THE RESTORATIONS

To achieve the best results, it is essential to select the best material for each specific situation. For the production of the crown frameworks used to restore the six maxillary anterior teeth, KATANA™ Zirconia YML in the shade NW appeared to be the ideal option. Their intaglio surfaces were treated with Esthetic Colorant (Kuraray Noritake Dental Inc.) in the shade OPAQUE to prevent a shining through of the discolourations found on some of the prepared teeth. After sintering of the frameworks in a high-temperature sintering furnace (Nabertherm) at 1,550° C, CERABIEN™ ZR porcelains were applied as illustrated below. For the creation of natural effects inside the restorations – i.e. between the layers of porcelain –, we use the internal stain technique (ILS). This procedure is very predictable and fast. Each step during porcelain build-up and staining was recorded with photos to monitor the entire process and to capture all information on the individual protocol steps. The porcelain veneers (Super Porcelain EX-3, Kuraray Noritake Dental Inc.) were produced on the refractory dies to restore the premolars in the maxilla and central incisors to second premolars in the mandible.

FIT ASSESSMENT AND TRY-IN

When the production process was complete, the restorations were placed on the solid models (printed master casts). This step is very important to validate the passive fit and contact points of each crown and veneer. Afterwards, it was time to try-in and check all the restorations intra-orally.

Fig. 25. Final restorations ready for fit assessment.

DEFINITIVE PLACEMENT AND FINAL OUTCOME

Refractory ceramic veneers were cemented via an adhesive protocol using a resin-based composite. Opaque glass ionomer cement was used to cement the zirconia crowns.

At the recall about one month after restoration placement, we saw amazing gum conditions and a happy, healthy and beautiful smile!

Case by Andreas Chatzimpatzakis

With CERABIEN™ ZR, Kuraray Noritake Dental Inc. offers a whole porcelain portfolio for the finishing of restorations based on zirconia. Originally developed for complex layering techniques, the synthetic feldspathic porcelain powders, liquid ceramics, internal and external stains allow for the creation of beautiful dental artwork. We love to work with the system as it offers consistent handling and mechanical properties, allowing us to produce predictable outcomes.

However, the complexity of the system with its huge number of different shades can pose challenges to less experienced users. This complexity is further increased when different substructure materials are used, as CERABIEN™ ZR works exclusively on zirconia, so that users would need to select and manage a second porcelain system when opting for a lithium disilicate framework, for example.

For dental technicians who would like to keep it smartly simple, the new CERABIEN™ MiLai line-up is certainly a great solution. Specifically developed for micro-layering on pre-shaded, highly translucent substructure materials such as lithium disilicate or a latest-generation zirconia, CERABIEN™ MiLai porcelains and internal stains may be applied in a thin (micro-) layer on restorations with a small (vestibular) cut-back. Just like CERABIEN™ ZR, the new system is based on synthetic feldspathic porcelain delivering consistent properties, but the line-up is reduced to 15 internal stains and 16 porcelains. As the CERABIEN™ MiLai has a firing temperature of 740 °C (1,364 °F), it works on oxide ceramics like zirconia, but also on reinforced silicate ceramics like lithium disilicate*.

*The material should have CTE value within 9.5~11.0×10^-6 /K (50~500 °C)

Consequently, the system may be used as the universal porcelain system for micro-layering on aesthetic ceramics. With its slim portfolio, it fits the philosophy of creating impressive restorations with fewer components, layers and bakes very well, as demonstrated in two different case examples below.

VENEERS BASED ON LITHIUM DISILICATE

Fig. 1. Six anterior veneers made of lithium disilicate (Amber Press LTA2 HASS Bio), designed with a slight cut-back to create the space needed for micro-layering.

Fig. 2. Restorations after the application of CERABIEN™ MiLai Value Liner 1 followed by wash firing and internal staining. This type of porcelain increases the value of lithium disilicate restorations. By staining the core, we control the chroma and add some internal characteristic effects. In this case, we added Cervical 2 to the marginal area and characterized the incisal third with Cervical 2 and Incisal Blue 1 & 2.

Fig. 4. Palatal view of the individualized restoration before the firing process.

Fig. 5. Restoration ready for try-in.

CONCLUSION

The two different cases confirm that CERABIEN™ MiLai works very well on lithium disilicate and zirconia. Despite the reduced number of stains and shades, it is possible to imitate most of the shades and individual effects found in natural teeth, which are important for lifelike outcomes. Hence, the new material is worth a try for everyone who prefers standardized and simplified procedures.

In 2017 Andreas visited Japan where he trained under the guidance of Hitoshi Aoshima, Naoto Yuasa and Kazunabu Yamanda and become International Trainer for Kuraray Noritake Dental Inc..

With improving mechanical properties and evolving (injection-based) techniques, the use of flowable composites is becoming increasingly popular as a permanent solution in the aesthetic zone. Consequently, the originally challenging task of shade matching becomes relevant with this material class as well. That is why Kuraray Noritake Dental Inc. introduces CLEARFIL MAJESTY™ ES Flow Universal – a flowable composite with an intuitive shade-matching concept.

Available in two flowabilities and two beautifully complementary shades, universal (U) and universal dark (UD), CLEARFIL MAJESTY™ ES Flow Universal turns shade matching into an effortless endeavour. Shade U is suitable for almost all posterior and anterior cavities and shades. UD (Universal dark) shows best results in cavities of shade B3 and beyond that are lacking a back wall, such as Class IV cavities. Hence, U or UD are intuitively selected – no shade guide needed. This is feasible due to a smart combination of an enamel-like translucency, dentin-like chroma and unique Light-Diffusion Technology (LDT). The placement procedure is simplified by the clever syringe design that reduces the risk of formation of air bubbles, extruding the composite without dripping, while the low stickiness facilitates handling and sculpting with the syringe tip. Once cured, the material seamlessly blends with the surrounding tooth structure. In this way, minimal effort is involved in the creation of beautiful restorations.

With a flexural strength over 150 MPa, a compressive strength over 370 MPa and high filler loading of 75, resp. 78 wt/%), CLEARFIL MAJESTY™ ES Flow Universal rivals with its mechanical properties those of conventional paste-type composites. Thanks to this, the material is suitable for use even for stress-bearing areas like occlusal surfaces. This opens the door to a wide range of applications, including restorations of all cavity classes, direct veneering, simplified restoration of multiple teeth with the flowable injection technique, and intraoral repairs. In addition, the mechanical properties provide for an easy, time-saving polishing procedure and long-lasting gloss. So well equipped, the material positions itself as a high-performance permanent restoration solution offering both aesthetic excellence and structural reliability.

For those users who would like to maximise their clinical efficiency without compromising on treatment quality, the combination with other high-quality materials of Kuraray Noritake Dental Inc.’s universal portfolio – e.g. with CLEARFIL™ Universal Bond Quick 2 – is highly recommended. Consisting of fewer components and requiring fewer steps, these products reduce the procedural complexity and smooth the way for great outcomes. More information about CLEARFIL MAJESTY™ ES Flow Universal and the whole universal portfolio is available online.

To meet the demands of modern dental practices, Kuraray Noritake Dental Inc. is continually refining existing materials and developing new ones. As part of this commitment, the company introduces CLEARFIL™ Universal Bond Quick 2, the latest advancement in dental bonding technology. Designed to enhance clinical workflows, this adhesive delivers robust performance across a wide range of applications.

The use of CLEARFIL™ Universal Bond Quick 2 provides a variety of benefits, made possible by the combination of proprietary Advanced Rapid Bond Technology, a newly designed filler dispersion method, and seamless integration with other essential products like restoratives and self-adhesive resin cements. Advanced Rapid Bond Technology features three monomers: the original MDP Monomer, Amide Monomer, and Urethane Tetra Methacrylate (UTMA) Monomer.

The Amide Monomer facilitates rapid penetration into the tooth structure,using its hydrophilic properties . This eliminates the need for waiting after application, saving time and minimizing the risk of contamination. This feature makes the product ideal for situations where moisture control is challenging. The newly added UTMA Monomer is a key component in creating a high-strength bonding layer that resists shrinkage forces. Meanwhile, the MDP Monomer, in combination with other well-matched components, ensures a consistent and durable bond to both enamel and dentin.

The new filler dispersion method provides two significant benefits: it enhances the product’s flowability without reducing the filler content, enabling easy application while forming a thin, uniform bonding layer. This minimizes the risk of pooling and helps maintain the original morphology of the prepared tooth.

CLEARFIL™ Universal Bond Quick 2 can be stored at room temperature (max. 25°C) and does not require shaking, making it ready to use at any time. Furthermore, it is well-suited for a variety of clinical scenarios, including direct restoration procedures, cementation of indirect restorations with self-adhesive resin cements, and core build-up procedures. A separate dual-cure activator is not required.

For clinicians seeking to maximize efficiency without compromising treatment quality, combining this adhesive with other high-quality materials from Kuraray Noritake Dental Inc.’s universal portfolio is highly recommended. These products, consisting of fewer components and requiring fewer procedural steps, simplify workflows and pave the way for exceptional clinical outcomes.
