In Zirconia, layered or monolithic, the final restoration is a hybrid of metal and zirconia. In the laboratory the metal insert is cemented into the zirconia for a complete metal connection of screw and abutment to the implant interface. This provides a great, cost effective, retrievable option when implant placement allows for both single and multi-unit bridge restorations. Directly screwing the final restoration to the Implant eliminates the possibility of cement being left behind upon insert, which can cause cement peri- implantitis. Retrievability since the crown is not permanently cemented, the restoration can be removed yearly, cleaned, and the tissue can be evaluated.
