EFFECTIVE FINISHING OF A ZIRCONIA FRAMEWORK WITH CERABIEN™ MiLai

‘Modern concepts are based on the smart combination of different materials.’

The implant-prosthetic restoration of edentulous jaws requires more than functional stability. Modern concepts are based on the smart combination of different materials. In the presented case, a titanium bar provides for a stable connection between the implants, while a zirconia framework offers the necessary strength and fracture resistance. Both materials stand out due to their high biocompatibility, the good soft tissue attachment properties of zirconia being particularly noteworthy. The real challenge in the selected type of restoration, however, begins with aesthetic realization. Micro-layering techniques promise efficiency combined with aesthetics – but this often comes with compromises, e.g. in terms of handling. With CERABIEN™ MiLai (Kuraray Noritake Dental Inc.), a new path is now being taken here.

MDT Andreas Chatzimpatzakis, Athens

The rapid development of all-ceramic framework materials such as zirconia and lithium disilicate calls for new veneering concepts. CERABIEN™ MiLai (Kuraray Noritake Dental inc.) picks up on the strengths of classic powder ceramics and optimizes them for the requirements of micro-layering – the reinterpretation of a classic, so to speak. The basis for this is provided by synthetic feldspathic ceramic technology, in which Kuraray Noritake Dental Inc. has decades of experience. The company developed its first synthetic dental ceramics back in the late 1980s – expertise that is now also used in the low-fusing porcelain system CERABIEN™ MiLai for micro-layering. Unlike natural feldspathic ceramics, the synthetic version provides for consistent properties without the need to adjust the formulation due to altering raw materials. This is reflected in stable coefficients of thermal expansion and a uniform particle distribution; prerequisites for aesthetic results and colour stability. Another decisive advantage is evident during the firing process: the special composition prevents micro-movements in the material during firing, which can lead to inhomogeneities and gray haze effects with conventional ceramics. This property is indispensable for micro-layering, as any irregularity, no matter how small, would be immediately visible in the thin ceramic layers.

INITIAL SITUATION

The presented case illustrates the technical procedure around the restoration of an edentulous maxilla. The prosthetic work was produced after the placement of six implants and their osseointegration. In consultation between the practice team around prosthodontist Dr Georgios Siavikis, laboratory technician and patient, the decision was made to restore the teeth with a bar-supported bridge construction. A CAD/CAM-fabricated titanium bar (Atlantis® BridgeBase, Dentsply Sirona) formed the basis. Due to its high manufacturing precision, it would provide for a passive fit of the reconstruction on the implants. The material of choice for the superstructure was zirconia, which was to be finalized using micro-layering due to the patient’s high aesthetic demands.

Fig. 2. Computer-aided design of the zirconia framework – transparent view revealing the BridgeBase.

Fig. 3. Computer-aided design of the zirconia superstructure.

WHY CHOOSE MICRO-LAYERING?

The decision to opt for micro-layering is based on tangible benefits: In addition to economic efficiency, the thin layer of porcelain provides a high level of safety and significantly reduces the risk of chipping. In addition, the ultra-thin porcelain layer enables a controlled approach to porcelain layering. However, we must be aware that with micro layering, around 80 to 90 percent of the restoration’s final shape is already created in the framework. Although this leads to maximum control during layering, it also places high demands on the selected framework material. With porcelain layer thicknesses in the micro range, the zirconia needs to be convincing in terms of aesthetics and mechanical strength. For our long-span bridge construction, we chose KATANA™ Zirconia HTML Plus (Kuraray Noritake Dental Inc.), a material that combines high strength with natural translucency. We deliberately opted for a disc in the shade A2 – one shade lighter than the desired target shade A3. This strategic choice enabled us to play with the colours during layering and implementation of the internal stain technique.

Fig. 4. Multi-Layered zirconia with a high strength and translucency used as a framework material.

WHY OPT FOR INTERNAL STAINING?

The internal stain technique is no longer an insider tip, but is one of the supreme all-ceramic disciplines. Kuraray Noritake Dental Inc. has perfected the technique over decades together with dental technicians. We particularly value the technique in our day-to-day laboratory work, as it gives restorations an individual touch that sets them apart from standard work. Unlike superficial stains, the internal staining creates a characterization from inside the restoration with a lively play of colours that unfolds naturally in changing light conditions.

Until now, it has been challenging to combine the advantages of the internal stain technique with those of micro-layering. Although we have put various approaches to a test and detected solutions that do work, we have always come up against technical limitations. The combination of both techniques – micro-layering and internal staining – places special demands on the porcelain system: It needs to allow characterization from the inside and at the same time be able to be processed in ultra-thin layers. CERABIEN™ MiLai closes the previous gap. As a low-fusing porcelain system, it combines the advantages of the internal stain technique with the efficiency of micro-layering. Being a powder-based porcelain system, the product may be used in the familiar way – only much more efficiently. The possibility of adjusting the consistency to individual needs gives us the precise control we need for minimal layer thicknesses. With 16 porcelains and 15 internal stains, the system remains manageable without compromising on design.

Fig. 5. The low-fusing porcelain CERABIEN™ MiLai is designed for micro-layering on zirconia and lithium disilicate.

FRAMEWORK PREPARATION

After milling and sintering, the framework in its cut-back design was processed systematically: The first step was to treat the zirconia surface with a diamond bur – under water cooling to avoid microcracks. In this phase, it is also possible to incorporate fine anatomical details such as mamelon structures or marginal ridges. To provide for a strong bond, the surface of the framework was then sandblasted with 50 μm alumina particles. In this context, it is important to apply a moderate pressure that conditions the surface without weakening the structure. Framework preparation was completed with ultrasonic cleaning for ten minutes. All this created the basis for a reliable bond between the framework and the veneering porcelain.

Fig. 6. Zirconia framework prepared for finishing.

INTERNAL STAINING MEETS MICRO-LAYERING

Next on the list was internal staining. It is often the smallest details that have the biggest effect – be it a prominent marginal ridge or an intensive cervical colouration. Sometimes, however, less is more. It is often a question of the dental technician’s artistic sensitivity and – of course – the individual situation. In this case, Tissue Red was used for a vivid effect of the gingival areas, while a combination of Cervical 2, Incisal Blue 1 and Mamelon 2 was chosen to give the teeth a three-dimensional depth effect. Subsequent micro-layering was carried out selectively: CCV2 in the cervical area, Creamy Enamel for lighter margins and LT1 for the desired standard translucency and opalescence. The gingiva was given its natural depth through a sophisticated interplay of shades and shapes – with a base of Tissue 1 and 5, while the keratinized areas were given their characteristic appearance with a 60/40 mixture of Tissue 1 and TX.

Fig. 7. Internal staining: Targeted application of the stains on the framework as the basis for the three-dimensional colour effect of the restoration.

Fig. 8. Micro-layering: Ultra-thin layering on the characterized framework gives the restoration its final shape and light dynamics.

What followed was the first bake. CERABIEN™ MiLai is a low-fusing porcelain. Its firing temperature of 740 °C is not only the enabler of its compatibility with various framework materials (zirconia, lithium disilicate), but also reduces the risk of distortion or micromovements causing unwanted changes in shape during repeated firings. Minor shape corrections were made after the first bake. In this step, a particular advantage of powder ceramics in micro-layering becomes apparent: they allow for precise modelling of even the finest structures and textures. The surface structure with its lively textures gives the work its natural appearance. The final glaze firing leveraged the self-glazing effect of CERABIEN™ MiLai.

Fig. 11. Lively surface structure with interplay of concave and convex areas both in the area of the teeth and the gingiva.

Fig. 12. Restoration in situ; edentulous maxilla with an implant-based zirconia bridge. The patient’s wishes regarding individual aesthetics are fulfilled thanks to internal staining and micro-layering (CERABIEN™ MiLai) – effectively, economically and safely.

EFFECTIVE AND FLEXIBLE

In the case presented, we combined the internal stain technique with micro-layering to fulfil the patient’s individual aesthetic demands. However, CERABIEN™ MiLai is just as suitable for micro layering without internal staining – fast, straightforward and effective. And this is precisely the advantage of this system: it offers the flexibility to go your own way – tailored to the respective situation and to the framework material (zirconia and lithium disilicate), eliminating the need to store different porcelain systems. Particularly useful: CERABIEN™ MiLai can be combined with the tried-and-tested CERABIEN™ ZR porcelain. Thanks to the low firing temperature, areas that have already been layered remain stable in shape and colour. The high versatility makes CERABIEN™ MiLai our preferred system for effective micro-layering. MiLai YOUR WAY – we have found our way with it and know that we have the right solution for every case.

‘THE HIGH VERSATILITY MAKES CERABIEN™ MILAI OUR PREFERRED SYSTEM FOR EFFECTIVE MICRO-LAYERING.’

CLEARFIL MAJESTY™ ES Flow Universal WINS RESEARCH AWARD

Kuraray Noritake Dental Inc. has just launched a flowable composite with a simplified shade concept: CLEARFIL MAJESTY™ ES Flow Universal. As published in the January/February 2025 issue of the US-based Dental Advisor, the brand-new product earned a prestigious Research Award for its convincing in-vitro performance.

PROPERTIES IN A NUTSHELL

In Europe, CLEARFIL MAJESTY™ ES Flow Universal was just launched in two viscosities – Low and Super Low, while in the United States, the Super Low variant is available. To provide for an effortless shade selection procedure, the material is equipped with a smart combination of an enamel-like translucency, dentin-like chroma and unique Light-Diffusion Technology (LDT). This leads to exceptional shade-matching abilities and allows for a minimal shade range of just two complementary shades – universal (U) and universal dark (UD). Once cured, the material naturally blends with the surrounding tooth structure.

 
Apart from intuitive shade selection, the flowable composite offers another major advantage: Its exceptionally high strength. With a flexural strength of 152 MPa and a compressive strength of 374 MPa, CLEARFIL MAJESTY™ ES Flow Universal (Super Low) is as strong as many paste-type composites. Consequently, it is suitable for use even in stress-bearing areas and indicated for:

• Direct restorations for all cavity classes, cervical lesions (e.g. root surface caries, v-shape defects), tooth wear, and tooth erosion
• Cavity base / liner
• Correction of tooth position and tooth shape (e.g. diastema closure, tooth malformation)
• Intraoral repair of fractured restorations
• Cementation of ceramic and composite inlays, onlays and veneers with less than 2 mm thickness

STUNNING IN-VITRO PERFORMANCE

The Super Low flowability variant offered the United States was tested in the Dental Advisor Biomaterials Research Center and compared to two other flowable composites. Among the properties evaluated were the materials’ flexural strength, modulus of elasticity, fracture toughness, compressive strength and radiopacity. Moreover, the investigators assessed the shade-matching ability of the materials in the context of restoring Class V cavities in A1, B2, C3, and D4-shaded denture teeth. Finally, they put the radiopacity and flow properties to a test.

 
CLEARFIL MAJESTY™ ES Flow Universal performed very well in all respects. Physical properties turned out to be among the highest of flowable composites and on a similar level as paste-type alternatives. Radiopacity was found to be ideal, as was the viscosity, as the material holds its initial shape after application. And although only two shades are offered, the investigators confirmed that the CLEARFIL MAJESTY™ ES Flow Universal matches a broad range of natural tooth shades.

Case by Andreas Chatzimpatzakis

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).

Fig. 1. Anatomically reduced crown structures made of lithium disilicate (Amber Press LT, shade A2).

Fig. 2. Crowns after the application of CERABIEN™ MiLai Value Liner 1 generally used to increase the value of lithium disilicate restorations, followed by wash firing.

Fig. 3. Situation after CERABIEN™ MiLai Internal Stains: A+ is applied in the cervical area to enhance the chroma, and Mamelon Orange 2 alternating with Incisal Blue 1 are used to imitate the mamelon structures in the incisal area.

Fig. 4. Crowns after the first and second bake with CERABIEN™ MiLai Porcelain LT1 applied in the cervical area to add translucency and opalescence to the enamel, E2 mixed with ELT (ratio: 60/40) to optimize the body area and LTx to boost the incisal translucency and opalescence.

Fig. 7. Natural translucency and internal optical structure revealed in transmitted light.

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.

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.

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.

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. 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.

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.
