1. An intervertebral implant configured to be inserted into a disc space between a first vertebral body and a second vertebral body and to provide fusion of the first vertebral body to the second vertebral body via biological bone fusion and screw fusion, the intervertebral implant comprising:
a top wall, a bottom wall, and first and second sidewalls, wherein the top wall, bottom wall and first and second sidewalls define a space capable of receiving bone filling for biological bone fusion, the top wall comprising a top surface, a bottom surface opposite the top surface, and first and second side surfaces, the first and second side surfaces configured to face first and second vertebral-bodies when the intervertebral implant is inserted into a disc space;
a first internal screw guide having a first bore extending from a first entry opening to a first exit opening, the first entry opening of the first internal screw guide formed at least partially in the top surface of the top wall such that no part of the first entry opening is formed in the first and second sidewalls and the first exit opening formed at least partially in the bottom surface of the top wall and at least partially in the first side surface of the top wall;
a first screw having a first threaded screw body and a first screw head, wherein the first screw is configured to be received by the first bore of the first internal screw guide at a position where at least a portion of the first threaded screw body projects through the first exit opening and the first screw head abuts a first surface within the first bore;
wherein the abutment of the first screw head and the first surface exerts a force against the first screw head and inhibits backout of the first screw from the first internal screw guide, and
wherein the first and second sidewalls exclude any portion of any entry opening of an internal screw guide.
