Clinical cases rehabilitated with different kinds of zirconias. (A) 3Y-TZP infrastructures fully veneered with feldespathic ceramic in a tooth-supported upper arch rehabilitation including single-crown and three-unit fixed dental prostheses (Clinical case conducted by Benalcázar-Jalkh EB, and Pegoraro LF, and Dental Technician M. Portaluppi). (B) Partially veneered monolithic zirconia used for full-arch implant-supported prosthesis. The buccal aspect of the teeth and gingiva were veneered to achieve esthetic results, while occlusal and palatal aspects were designed in monolithic zirconia to reduce the risk of porcelain chipping (Clinical case conducted by Laura Firmo de Carvalho and Dental Technician Marcos Celestrino). (C) 5Y-PSZ, or “ultra-translucent” zirconia, was used to manufacture an implant-supported single crown over a Ti-base abutment (Clinical case conducted by Raphaelle SM de Sousa and Dental Technician/DDS Ricardo Tanaka). (D) Full-arch tooth-supported prosthesis manufactured in a monolithic multilayered zirconia (3Y-TZP/5Y-PSZ) and stained to achieve esthetic results (Clinical case conducted by Benalcázar-Jalkh EB, Bonfante EA, and Dental Technician M. Celestrino).
