Screw-retained crowns are a safe and predictable implant option in comparison to traditional cement-based crowns. They ensure success for every implant case by eliminating the primary cause of implant failure, which is excess cement left below the margin during oral surgery. Screw-retained crowns use a screw instead of wet cement to secure a crown to the abutment. and base. These screws do not interfere with esthetics, because the screw access hole is filled after surgery. They are easily retrievable for maintenance by clinicians.
