CATEGORY 62 AUSTRALASIAN DENTIST CLINICAL (all Ivoclar Vivadent, Liechtenstein). The occlusion check-up was conducted using 12 μm articulating films (Bausch, USA). Necessary arrangements were done using a high-speed handpiece, after which the occlusal surfaces were polished using a two-step ceramic polishing system (OptraGloss, Ivoclar Vivadent, Liechtenstein). The final profile of the happy patient can be seen on picture 22. Conclusion Metal-free ceramics are used worldwide as a synonym for aesthetic restorations. However, in addition to aesthetic requirements, functional demands often require high-strength materials, which can withstand high occlusal forces in certain areas. In this context, wide-span bridges, with two pontics or splinted bridges place high demands on metal-free ceramic restorations. Fortunately, the mix of 3Y-TZP and 5Y-TZP zirconia powders enables an intriguing combination of strength and aesthetics. Involving GT-Technology, materials such as IPS e.max ZirCAD Prime provide a reliable and highly aesthetic alternative to old fashion metal-ceramic reconstructions. u The dental restorations were made by DT Ivan Unfeter Fig. 18: Final 3Y/5Y zirconia restorations on the model, in combination with layering composite in gingival area.

About Prof. Dr Danimir Jevremović 2001 Graduated School of Dentistry, Uni Belgrade 2002 Assistant Uni Belgrade 2005 MSc, Uni Belgrade 2007 Specialization Dental prosthodontics 2008 PhD, Uni Belgrade 2009 Assistant professor, School of Dentistry Pančevo 2014 Associate professor, School of Dentistry Pančevo 2017 Professor, School of Dentistry Pančevo 2019 Vice Dean for Science, School of Dentistry Pančevo 2022 Vice Dean for international cooperation, School of Dentistry Pančevo Dr Danimir Jevremović was born in November 1978. He graduated from the Faculty of Dentistry with all the highest marks and became the youngest and the best graduate on the University of Belgrade, Serbia. During his master studies (2005), specialization (2007) and doctoral thesis (2008) he dealt with modern all-ceramic systems, adhesive restorations and principles of minimally invasive dentistry. Known for his artistic understanding of dentistry, he derives prosthodontics as an intervention of smile beauty and team talent. In 2009 he became an assistant professor at the University Business Academy, School of Dentistry, Pančevo. He broadened his ideas through exchange visits to Liechtenstein, Switzerland, Germany, England and Wales. In 2015, he became an associate professor, and in 2017, he received the title of professor at the same faculty. Since 2017, he has been the chairman of the Dental Prosthodontics Clinic, the head of the Ethics Committee and the head of the Department of Clinical Dentistry at the Faculty of Dentistry in Pančevo. Since 2019, he has been Vice Dean for Science at the Faculty, and since 2022, he has been Vice Dean for International Cooperation. He is the author of one book, two monographs and a practical notebook for dental students. He is the author and co-author of numerous scientific publications, a participant in international projects, and a lecturer and demonstrator at national and international symposia. To achieve both high strength and high aesthetic requirements, IPS e.max ZirCAD Prime was used (Ivoclar Vivadent, Liechtenstein). The IPS e.max ZirCAD Prime discs are the material of choice for this type of indication. In addition, this material offers the option of layering on the substructure, in this case, with pink composite to achieve red aesthetics in the gingival area (SR Nexco, Ivoclar Vivadent, Liechtenstein). The aesthetic properties of the final restoration can be seen in the pictures 18 – 20. The single crown was also made out of the IPS e.max ZirCAD Prime, while the premolar veneer was facricated out of the lithium-disilicate glass ceramic IPS e.max CAD (Ivoclar Vivadent, Liechtenstein). Due to its light-optical and other material properties, this material is ideal for the production of veneers, among other restoration types. All restorations were cemented with Variolink Aesthetic DC (Ivoclar Vivadent, Liechtenstein). The purpose of using a composite cement for cementing zirconia crowns is to achieve a reliable, aesthetic marginal adaptation, rather than just high retention properties (Fig. 21). The zirconia restorations were pretreated with Monobond Plus, the etchable lithiumdisilicate veneer was treated using Monobond Etch&Prime, while the teeth surfaces were treated with Adhese Universal Prof. Dr. Danimir Jevremovic University Business Academy School of Dentistry Žarka Zrenjanina 179 26000 Pancevo, Serbia
