Immediate Stabilization and Function / Polyceramic Material Fused to Metal: Placement of Two Immediately Functioning Implants and their Restoration with Two Polyceramic to Metal Crowns and the Restoration of Two Natural Teeth with All-Ceramic Crowns

This case demonstrates the replacement of a four unit maxillary anterior fixed prosthesis with the placement of two immediately functioning implants and their restoration with two polyceramic to metal crowns as well as the restoration of two maxillary lateral incisors with all-ceramic crowns.
