ABSTRACT
Aim of the study The purpose of this work is to study the possibility of manufacturing zirconia restorations in accordance with the properties and characteristics of the materials, correlated with digital technologies. Materials and methods In order to reestablish the aesthetic aspect of a patient who came to our dental office, we had the option to fabricate using CAD-CAM technology, a fixed prosthetic restoration made from a zirconium oxide (ZrO₂) framework – Katana HTML Plus, covered with layered ceramic IPS e.max Ceram, consisting of 4 elements in the anterior area of the maxillary arch, for the incisors – 1.1, 1.2, 2.1, 2.2. Results CAD/CAM technology was used for both main steps – software CAD to analyse and elaborate the design of the Zirconia framework and then, for milling, the CAM machine milled the structure in zirconia disc, followed by sintering and each part of the restoration was covered with layers of ceramic for aesthetic aspect. Conclusions Evaluating and comparing the strength and translucency properties of zirconia allows the possibility to choose the most appropriate treatment option for the patient, for the anterior area of the dental arch, to restore aesthetic and functional aspects.
