Bicon Integrated Abutment Crowns™ / Polyceramic Material Fused to Metal: Bilateral Sinus Floor Augmentation Grafts, the Placement and Removal of Three Immediately Placed and Functioning Implants, the Placement of Eleven Maxillary Implants and their Restoration with Nine Integrated Abutment Crowns™ and a Three-Unit Polyceramic to Metal Fixed Prosthesis
This case demonstrates the sequencing and execution of treatments for the restoration of an edentulous maxilla with bilateral sinus floor augmentation grafts, the placement and removal of three immediately placed and functioning implants, the placement of eleven maxillary implants and their restoration with nine Integrated Abutment Crowns™ and one three-unit polyceramic to metal fixed prosthesis.
