White and pink aesthetics: a distinctive approach using KATANA™ Zirconia Multi-Layered
Finishing of six anterior elements with gingival flange produced from high-strength KATANA™ Zirconia – from surface morphology adjustments to micro-layering.

FOREWORD
Innovative high-translucency, multi-layered variants of zirconia feature well-balanced optical and outstanding mechanical properties. Their use allows for better outcomes of laboratory-based digital workflows and makes it possible to fulfil the increasing functional demands we are facing in the clinical environment. Depending on individual, case-specific needs, laboratory technicians can select a suitable zirconia and the distinctive technical approach delivering the desired outcomes. For this purpose, it is essential to develop a deep understanding of the available materials, their chromatic adaptability and general aesthetic potential, the design and finishing options and their correct technical implementation as well as the most important case-specific selection criteria. In combination with advanced laboratory-based communication skills, this knowledge will enable us to fulfil or even exceed the patient’s expectations by delivering a highly aesthetic, functional restoration.
Let us assume that a six-unit anterior bridge with gum area on implants is needed. For the ideal prosthetic solution, white aesthetics is fundamental, but a perfect harmony will only be achieved if the gingival texture and colour is reproduced in a natural way, as the gingiva is considered the “aesthetic frame” of the dental restoration. Our solution is a monolithic restoration made of KATANA™ Zirconia YML, finished using a 3D micro-layering technique with CERABIEN™ ZR.

OBJECTIVE
In this Master Course, you will acquire the theoretical knowledge needed to select the appropriate zirconia and finishing technique for every individual case and the practical skills required for the finishing of the six-unit bridge with gum area – from surface texturing to 3D micro-layering on teeth and gums.

YOU WILL LEARN TO:

Select the appropriate type of KATANA™ Zirconia ML
Re-finish pre-sintered zirconia
Optimize the sintering process
Re-finish and prepare the zero cut-back elements
Accomplish micro-layering with CERABIEN™ ZR porcelain
Perform mechanical finishing and polishing
