ZIRCONIA. CHARACTERISTICS AND TECHNOLOGY FOR FIXED RESTORATIONS

Abstract

Aim of the study For oral rehabilitation, zirconia is a biomaterial material used for veneers, crowns, fixed partial denture, root devices or implants and implant abutments. Materials and methods In order to apply and follow the technological algorithm for the realization of prosthetic works in zirconia, through the CAD/CAM technique, we choose for the rehabilitation of a clinical case, as treatment option, three bridges and a single crown, made of integral zirconia. Results We proceeded to the actual design of the future fixed prosthesis, respectively of the zirconia elements, with the help of the CAD/CAM technology. After scanning the casts, we designed the elements, establishing the limits of the edges, their dimensions and thickness. The completed prosthetic work is saved for a later transmission to the milling machine (CAM technique). Conclusions The characteristics of zirconia materials have as result fixed prosthetic restorations that fulfil both functional and aesthetic requirements, so, the specific technological algorithm require a good professional training.
