Made for lithium disilicate 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.

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. Dental technician: ANDREAS CHATZIMPATZAKIS Andreas graduated from the Dental Technology Institute (TEI) of Athens in 1999. During his studies he followed a program at the Helsinki Polytechnic Department of Dental Technique, where he trained on implant superstructures and all ceramic prosthetic restorations. As of 2000, he is running the ACH Dental Laboratory in Athens, Greece, specialized on refractory veneers, zirconia and long span implant prosthesis. 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.. 13. mai 2025 Dental Technician Kuraray Noritake Prosthodontics Clinical Case CERABIEN MiLai Prosthetic dentistry Lab Dental Ceramics CZR FC Pastestain CERABIEN ZR FC Paste Stain Vaata toodet CERABIEN MiLai Vaata toodet Uudiskirja tellimine
