An anterior cervical plate system is provided. The plate is configured to receive bone screws for attachment to and immobilization of adjacent vertebrae of the spine. The system includes a cup retained inside a through hole of the plate by a cup retainer. A bone screw is retained inside the cup by a lock that is movable between a locked position and an unlocked position. The cup is permitted to angulate forward and backward with respect to the plate and the bone screw is permitted to angulate conically with respect to the cup to provide a plate system with extreme angulation for the bone screw.
