Nuove soluzioni riabilitative mediante corone su impianti in zirconia

Abstract

Objectives To describe an easy, rational and ergonomic method to obtain crown restorations on zirconia implants. Materials and methods The peculiar feature of this new solution is building simultaneously a structure that is both abutment and framework. From the diagnostic wax-up of crowns, the technician makes for any crown a wax structure that simulates both the form of the abutment and that of the future framework. This wax structure is processed by the Procera Piccolo scanner and the data obtained are sent to the firm laboratory in Sweden where the corresponding zirconium oxide structure is produced. Then the structure is sent back to the dental technician who will finish the ceramic work. Results This new system allows to simplify and to standardize the production reducing the operator-linked variability and the time necessary to build a prosthesis. Conclusions In comparison to the traditional two-steps techniques (i.e. production of the abutments and production of the prosthesis), this new system allows to obtain in the same time a single structure while reducing time and saving money necessary to build a prosthesis.
