Zygomatic implant based oral rehabilitation: State of the art and proposed criteria for success

To overcome the original surgical technique (OST) drawbacks, a novel approach, named The Zygoma Anatomy-Guided Approach (ZAGA), has been coined. With this refinement, no window or slot is opened. A classification describing the variations of the zygomatic buttress anatomy will help the surgeon to choose the osteotomy. Accordingly, the path of the implant body may vary from a total intra-sinus to a total extra-sinus one. The final achievement will be a patient specific therapy. Rehabilitation using zygomatic implants (ZI), especially if those implants are located extra maxillary, is different from regular implant treatment. Currently, the way the results of ZI are reported in the literature lacks of a standardized systematic. Specific criteria to describe success/survival of ZI, including a standardized way to report on rhinosinusal status are necessary. The purpose of this book/thesis is to depict a systematic to provide a patient specific therapy through The Zygoma Anatomy-Guided Approach (ZAGA); to portray the ZAGA results and finally to compare the outcomes of the OST and ZAGA techniques using specific success criteria for ZI, named as the Zygomatic Success Code (ZSC).
