In part two of this veneer workflow, Roberto Rossi completes the restoration by applying CERABIEN™ MiLai lusters to the pre-stained and sintered KATANA™ Zirconia YML. Watch as he enhances surface texture, gloss, and lifelike detail through precise finishing techniques.

With just a few simple steps, Roberto creates depth, dynamic light effects, and natural contours that rival real enamel. The process is intuitive and efficient, delivering a high-end finish—culminating in a final self-glazing fire for a polished, natural result.

An intelligent solution for dental technicians seeking efficiency without compromising on aesthetics.

In the first part of this aesthetic veneer workflow, dental technician Roberto Rossi demonstrates how to apply internal stains to KATANA™ Zirconia YML. This crucial step enhances the restoration by adding depth, translucency, and natural character from within.

After refining the anatomy and surface texture, Roberto skillfully blends and applies selected shades such as A+, Fluoro, and Incisal Blue. These shades create depth, opalescence, and inner vitality that radiate through the final restoration.

A must-watch for dental technicians looking to elevate their zirconia restorations with advanced, yet straightforward, internal staining techniques.

EUROPEAN KOLS EXPERIENCE INNOVATION AND CRAFTSMANSHIP IN JAPAN

This September, seventeen of Kuraray Noritake Dental’s Key Opinion Leaders (KOLs) from across Europe—representing nine countries—embarked on a remarkable journey to Japan. The program offered a rare opportunity to experience the heart of Kuraray Noritake Dental’s culture of innovation, craftsmanship, and collaboration.

A JOURNEY OF INSIGHT AND INSPIRATION

The tour began in Tokyo, where the group traveled by bullet train to Nagoya to explore some of Japan’s cultural and professional landmarks. Visits to Nagoya Castle and the historic Noritake Garden provided glimpses into the artistry and heritage that continue to inspire our company’s ceramic technologies today.

That evening, an official dinner in Nagoya brought together the European guests and key members of the Kuraray Noritake Dental team, including Ms. Kiyoko Ban, Mr. Yoshihisa Yamada, and Mr. Kazuhiro Yamada. It was an evening filled with rich conversations, meaningful connections, and a shared vision for the future of dental excellence.

FROM CONCEPT TO CREATION: VISITING THE MIYOSHI AND NIIGATA FACTORIES

The following day, the KOLs visited the Miyoshi Factory, where the company’s ceramic products such as KATANA™ Zirconia are manufactured, and  attended insightful presentations by their European peers — including Jorgen Gad, Sophie Dallem, Dumitru Leahu, Marios Georgoulis, Stratos Chatzichristos, and Kamila Krzepkowska — followed by a comprehensive factory tour and in-depth discussions  with R&D experts on zirconia and dental lab materials, providing unique professional insights.

A CONCEPT EVEN FOR AESTHETICALLY DEMANDING CASES

The micro-layering technique is regarded as a more efficient, streamlined approach used as an alternative for full porcelain layering. It requires aesthetic, high-strength ceramics like lithium disilicate or zirconia as a base and – ideally – a set of porcelains specifically designed for reduced layer thicknesses that allows users to focus on imitating the characteristics of enamel. A high-quality example is CERABIEN™ MiLai (Kuraray Noritake Dental Inc.). Consisting of a set of internal stains and porcelains with a firing temperature of just 740 °C and a coefficient of thermal expansion in the range of 9.5~11.0×10-6/K (50 °C – 500 °C), this product works well on lithium disilicate and zirconia.

Its aesthetic potential is surprisingly high: Depending on case-specific requirements, users are given the choice between maximum efficiency using a single-bake technique and maximum aesthetics achieved with more complex layering. The latter option is demonstrated below using the example of six maxillary anterior veneers.

TRULY BEAUTIFUL OUTCOMES POSSIBLE

This case example reveals that CERABIEN™ MiLai is much more than just a maximum-efficiency solution: With the current line-up of porcelains and internal stains, truly beautiful restorations can be produced. Hence, users are given high flexibility regarding not only the high-strength framework material they prefer, but also the effort and time they would like to invest. This makes CERABIEN™ MiLai a versatile porcelain system that meets many needs and covers a wide range of applications in the dental laboratory.

Kaasaegses hambaravis on suur nõudlus materjalide järele, mis ühendavad käsitsemismugavuse ja efektiivsuse esteetiliste ning vastupidavate tulemustega. Sellised materjalid aitavad hambaarstidel saavutada soovitud tulemusi tõhusamalt, võimaldades neil pühendada rohkem aega patsientidega suhtlemisele.

Direktsete restauratiivsete ravimeetodite puhul mõjutab valitud vaigukomposiit oluliselt nii protseduuride lihtsust kui ka lõpptulemuse kvaliteeti. Seetõttu on universaalsed pastatüüpi komposiidid, nagu CLEARFIL™ MAJESTY ES-2 Universal (Kuraray Noritake Dental Inc.), muutumas üha populaarsemaks. Sama ettevõte on toonud turule ka voolava komposiidi CLEARFIL™ MAJESTY ES Flow Universal, mis pakub sarnaseid eeliseid. Need on esitatud allpool vastustena teil tekkida võivatele küsimustele.

Kuidas saavutada esteetilisi ja vastupidavaid restauratsioone, säilitades samas voolava materjali kasutusmugavuse?

CLEARFIL™ MAJESTY ES Flow Universal on voolav komposiit kahe teineteist täiendava tooniga, mis võimaldavad intuitiivset toonide sobitamist ja sobivad mitmesugusteks restauratiivseteks protseduurideks. See ühendab praktilised voolavusomadused, suurepärase toonide segunemise võime ning silmapaistvad mehaanilised omadused.characteristics with advanced shade-blending ability and outstanding mechanical properties.

Mis on CLEARFIL™ MAJESTY ES Flow Universal?

CLEARFIL™ MAJESTY ES Flow Universal on valguskõvastuv röntgenkontrastne komposiit, mis on ette nähtud kasutamiseks erinevates kliinilistes olukordades ning on saadaval kahes viskoossuses ja kahes toonis. See põhineb nanotäiteosakeste tehnoloogial, mis tagab kontrollitud voolavuse, hea läike püsivuse ja loomuliku välimusega restauratsioonid. Komposiidi sulandumine hambastruktuuri saavutatakse tänu emaililaadse läbipaistvuse, dentiinilaadse värvsuse ja valgusdifusiooni tehnoloogia (LDT) nutika kombinatsiooni abil. Emaililaadne läbipaistvus võimaldab valgusel materjalist läbi tungida, parandades selle värvi sobitumist ümbritsevasse hambastruktuuri. LDT muudab restauratsioonid valguse hajutamisel sarnaseks emaili ja dentiiniga. Koos täpselt tasakaalustatud värvsusega aitavad need omadused tagada materjali sujuva optilise sulandumise ümbritsevasse hambastruktuuri.

Kus saab CLEARFIL™ MAJESTY ES Flow Universali kasutada?

See voolav komposiit on ette nähtud väga erinevateks restauratiivseteks kasutusvajadusteks. Võimaldades kõike alates I–V klassi restauratsioonidest kuni aukude ja fissuuride sulgemise ning parandusteni sobib see materjal nii konservatiivseteks kui ka ulatuslikeks raviskeemideks.

CLEARFIL™ MAJESTY ES Flow Universali saab kasutada järgmistel juhtudel.

• Direktseteks restauratsioonideks kõikide kaviteediklasside korral ning hambakaela kahjustuste (nt juurepinna kaaries, V-kujulised defektid), hammaste kulumise ja erosiooni raviks.
• Kaviteedi aluskihina / lainerina.
• Hammaste asendi ja kuju korrigeerimine (nt diasteemi sulgumine, hammaste väärareng).
• Murdunud restauratsioonide suuõõnesiseseks parandamiseks.

Kuidas toimub toonide valik?

CLEARFIL MAJESTY™ ES Flow Universaliga on sobiva tooni leidmine ülimalt lihtne. Kaks üksteist täiendavat tooni – universaalne (U) ja universaalne tume (UD) – võimaldavad toone sobitada lihtsalt ja intuitiivselt, ilma et toonijuhendit oleks vaja kasutada. Toon U sobib enamikeks esi- ja tagahammaste restauratsioonideks. UD annab parima tulemuse tumedama tooniga hammaste puhul (B3 ja tumedamad), kui ümbritsevat hambakude on vähe, sealhulgas III ja IV klassi kaviteetide korral. Saate valida kõige sobivama tooni kaviteedi klassi ja patsiendi vanuse põhjal.

Värvi sobitamine esi- ja tagahammaste restauratsioonidega.

Mis on CLEARFIL™ MAJESTY ES Flow Universali toime taga?
