The present invention provides a dental implant jig, a set thereof, a drilling bar, and a set thereof, whereby accurate drilling can be implemented in a safe, easy, and inexpensive manner. In the present invention, the jig is provided to a drilling bar of a dental handpiece in order to guide the position and/or direction of drilling designed to form a hole for embedding an implant fixture, and is integrated into a shank occupying the space between the part where the drilling bar is mounted to the handpiece at one end and the blade part at the other end to form a guide part that rotates about the axis of the shank together with the shank, is concentric with the shank on the outside of the shank, and has a greater diameter than the shank has.
